                    <title>Background</title>
                    <p>This paper analyzes the mechanism of the proliferation and disappearance of graphical characters in the manga 
                        <italic toggle="yes">Dragon Ball</italic>, a globally successful media franchise. 
                        <italic toggle="yes">Dragon Ball</italic> was serialized by Japanese manga artist, Toriyama Akira (1955&#x2013;2024), in 
                        <italic toggle="yes">Weekly Shonen Jump</italic> magazine between 1984 and 1995. The manga, published in 42 volumes, was animated for TV from 1986 to 1996 as 
                        <italic toggle="yes">Dragon Ball</italic> and

                    <title>Methods</title>
                    <p>In support of the arguments on animation, such as Susan Napier&#x2019;s metamorphosis, Sergei Eisenstein&#x2019;s plasmaticity, and theories on characters in anime and manga studies, this paper analyses visual properties of characters in Toriyama&#x2019;s 
                        <italic toggle="yes">Dragon Ball</italic>, with a special focus on the graphical and biological reproduction.</p>

                    <title>Results</title>
                    <p>This paper found that characters in 
                        <italic toggle="yes">Dragon Ball</italic> operate as a vessel for the shape-shifting fluidity of ink lines. The free kinetic movement of lines results in the graphical proliferation of characters and reproduction devoid of sexual expression. This is a version of the &#x201c;abjection&#x201d; &#x2014; a reaction of the subject to reject familiar things as something horrific &#x2014; that Napier argued regarding metamorphosis in turn-of-the-century Japanese anime. In 
                        <italic toggle="yes">Dragon Ball</italic>, muscular men&#x2019;s battles hide the potentially grotesque graphic/biological proliferation of the characters. What stops this medium-specific proliferation of images is light as the lack of ink, a media-aesthetic element inherent to manga and anime. It is not flesh-and-blood combat but energy waves that inflict death on the villains who resurrect even from a single cell, just as lines drawn in ink multiply endlessly.</p>

                    <title>Conclusions</title>
                    <p>These findings offer rich insights into the history of visual popular media in post-war Japan. The glow of the energy waves expressed by the lack of ink echoes the repeated motif of mass destruction in the history of Japanese anime and manga, which reminds us of the extinction of lives in the atomic bomb explosions.</p>

                <label>Revised</label>
                <title>Amendments from Version 1</title>
                <p>This revised version of the article addresses comments raised by two peer reviewers. The primary changes are as follows. First, a footnote has been added in Section 2 engaging with Thomas Lamarre's concept of animetism (
                    <italic>The Anime Machine</italic>, 2009). While Lamarre's framework addresses the moving image and the layering technology of cel animation, the note situates the present study's focus on the static medium of manga in productive relation to this influential body of work. Second, an additional chapter reference has been added in Section 3.3 to strengthen the grounding of the visual argument in the primary source material. Third, the conclusion has been expanded to articulate more explicitly the broader stakes of the paper's analytical framework: the methodology developed here&#x2014;tracking how the medium-specific properties of ink and line become encoded as graphical reproduction&#x2014;is transferable to other manga and anime in which bodily transformation and destruction are central motifs, and connects the formal analysis to Japan's postwar visual imagination more directly than the previous version.</p>

            <title>1. Introduction</title>
            <p>Several initial volumes of the 
                <italic toggle="yes">Dragon Ball</italic> manga series are adventure stories in a multispecies world with an oriental and sci-fi touch. Modeled after 
                <italic toggle="yes">Journey to the West</italic> &#x2014; a 16
                <sup>th</sup>-century Chinese novel depicting the legendary Buddhist monk&#x2019;s pilgrimage to Central Asia and India &#x2014; the manga series follows Son Goku, a monkey-tailed boy. The wild boy who grew up in the countryside meets Bulma, a city girl who embodies the sci-fi elements of 
                <italic toggle="yes">Dragon Ball.</italic> With a father who is an inventor and president of Capsule Corporation, which develops and manufactures Hoi-Poi capsules that allow various machines to be carried around in the form of small capsules, Bulma shows off high technologies to the boy who has never even met a girl before. They travel the world in search of the seven Dragon Balls, which are likely to grant a wish of the possessor. This idyllic adventure storyline in a world filled with demi-humans, aliens, and animal people who understand human languages gained relatively little popularity; however, in response to readers&#x2019; expectations, the genre was gradually switched to battle manga, which emphasized combat with evil antagonists (
                <xref ref-type="bibr" rid="ref25">Watanabe, 1995</xref>, 262-264). The battle element and muscular characters, rather than the early adventures, supported the worldwide popularity of 
                <italic toggle="yes">Dragon Ball.</italic>
            </p>
            <p>The question of where the source of 
                <italic toggle="yes">Dragon Ball</italic>&#x2019;s global popularity lies demands precise discussion. The change of genre from adventure to battle can explain that the main attraction of this work is the fight between muscular men. For example, Bounthavy 
                <xref ref-type="bibr" rid="ref21">Suvilay (2018, 250-267)</xref> points out that 
                <italic toggle="yes">Dragon Ball</italic> expresses unique masculinity through the influence of the sports manga narrative tropes and kung fu stars such as Jackie Chan and Bruce Lee, although not intact by comical elements. Bandai, which manages the copyrights, has developed an abundance of figures of muscular soldiers and fighting video games. Inexpensive figures have been available on 
                <italic toggle="yes">gachapon</italic> vending machines in Japan since the 1980s when the manga was serialized in the weekly magazine. Presently, the franchise offers expensive, realistic figures for adults through a sales promotion strategy called 
                <italic toggle="yes">Ichiban Kuji</italic>. On the side of consumers and fans alike, Dragon Ball draws upon the appeal of massively muscular characters. Several male athletes and rappers who sell their masculinity express themselves as fans (
                <xref ref-type="bibr" rid="ref10">The Know, 2019</xref>). However, the story of 
                <italic toggle="yes">Dragon Ball</italic> is not simply a battle of bloodthirsty men. For example, Piccolo and Vegeta, who were enemies in the first half of the story, awaken to fatherhood, and Gohan, the strong son of the protagonist, hates fighting and tries to avoid it (
                <xref ref-type="bibr" rid="ref18">Oya, 2023</xref>, 257-269). Hence, what place do the fights between muscle-bound men, which are a significant part of the work, have in the overall world of 
                <italic toggle="yes">Dragon Ball</italic>?</p>
            <p>To answer this question, this paper analyzes the images in the 42 volumes and examines the complex potential of this text. By focusing on the visual representation of the manga, rather than on the narrative, this paper reveals that biological reproduction and the fear of it are embedded in the muscular battles in 
                <italic toggle="yes">Dragon Ball.</italic> Cell, one of the major villains of the manga series, gives birth to seven organisms, called Cell Juniors, to match the number of warriors on the side of the protagonists (
                <xref ref-type="fig" rid="f1">Figures 1</xref> and 
                <xref ref-type="fig" rid="f2">2</xref>) (Toriyama, Ch. 407). Cell is an artificially created life form whose sex is not explicitly stated and does not seem to reproduce sexually through the male-female binary. Cell was created to defeat Goku; therefore, the manga foregrounds the battles with the men on the protagonist&#x2019;s side. Thus, if viewed emphatically, Cell&#x2019;s metaphorical &#x201c;delivery&#x201d; scene is discordant with its hungry-for-a-fight masculinity, an undeniable attraction of 
                <italic toggle="yes">Dragon Ball.</italic> By analyzing the graphic elements whose meanings are irreducible to the story, as in the case of Cell, this paper finds that biological reproduction challenging the appeal of fighting muscular men appears inconspicuously everywhere.</p>

            <title>2. Methods: Metamorphose, plasmaticity, and sexuality in anime and manga studies</title>
            <p>This study mobilizes discussions in both manga and anime studies to analyze Toriyama&#x2019;s 
                <italic toggle="yes">Dragon Ball.</italic> The two media have different specificities: manga constitutes ink line drawings on paper, while animation is the continuous display of pictures to indicate movement. However, both media use line drawings. The lines drawn by human hands contain temporality and motility through the movement of hands. During the early film era of the 1890s and 1910s, there existed a mode of performance known as lightning sketch, in which an artist would draw a picture in front of an audience and show how the picture gradually changed (
                <xref ref-type="bibr" rid="ref9">Klein, 1993</xref>, 23). This mode of performance embodies the embeddedness of kineticism and temporality in the experience of viewing line drawings. One of Edison&#x2019;s early films including elements of the lightning sketch, 
                <italic toggle="yes">the Enchanted Drawing</italic> (1900), embodies the media continuum between still line drawings and early animation. The first half shows an unedited shot of an artist drawing a bald, middle-aged man, a wine bottle, and a glass on a canvas placed in front of the camera. In the second half, the camera&#x2019;s position does not move, but cut editing is used to express a trick effect. The artist takes the drawn wine bottle and glass as real objects and gives the wine to the drawn image of the middle-aged man, causing his expression to change to laughter. 
                <italic toggle="yes">The Enchanted Drawing</italic> reveals the kinetic qualities of line drawings, regardless of media and the spectators&#x2019; ability to perceive them.</p>
            <p>The importance of such kineticism gradually increased throughout Toriyama&#x2019;s career, from 
                <italic toggle="yes">Dr. Slump</italic> (1980-1984) to 
                <italic toggle="yes">Dragon Ball.</italic> From the beginning of 
                <italic toggle="yes">Dr. Slump</italic>, Toriyama&#x2019;s drawings have been an excellent balance of meticulously drawn machines, such as motorcycles and robots, and pop-deformed humans, which was exceptional by the standard of Japanese manga in the early 1980s. This visual sensibility was already evident in his reflections on the craft: in a manga published in 1982&#x2013;84 that teaches how to draw manga, Toriyama engages with Tezuka Osamu&#x2019;s manga semiotics, in which characters are created by combining symbols (
                <xref ref-type="bibr" rid="ref23">Toriyama and Sakuma, 1985</xref>), touching on concepts of perspective and motility, albeit briefly.</p>
            <p>However, unlike 
                <italic toggle="yes">Dragon Ball</italic>, 
                <italic toggle="yes">Dr. Slump</italic> does not represent the relative positions of several figures in the three-dimensional space and the kinetic dynamism between them. The latter half of 
                <italic toggle="yes">Dragon Ball</italic>, which shifted to the battle genre depicting the physical confrontation of characters, does not bother with where the battle occurs. The battles take place in an abstract, featureless space, such as some wilderness and the Chamber of Spirit and Time. This can be seen in the fight between Goku and Jackie Chun, a disguise of Kame-Sen&#x2019;nin, in the early episodes (
                <xref ref-type="fig" rid="f3">

            <p>Rather than discussing the story of 
                <italic toggle="yes">Dragon Ball</italic>, this paper analyzes it as line-drawing images in which kineticism is embedded. In this regard, Susan Napier&#x2019;s 
                <italic toggle="yes">Anime from Akira to Princess Mononoke: Experiencing Contemporary Japanese Animation</italic> (2001) and its updated edition, 
                <italic toggle="yes">Anime from Akira to Howl&#x2019;s Moving Castle</italic> (2005) are important studies discussing metamorphosis in Japanese anime. The books are intended as a systematic approach to the various Japanese animations of the time, using Napier&#x2019;s three modes &#x2014; &#x201c;apocalypse,&#x201d; &#x201c;festival,&#x201d; and &#x201c;elegy&#x201d; &#x2014; as a rough classification framework (
                <xref ref-type="bibr" rid="ref16">Napier, 2005</xref>, 12-13). Across these modes, Napier discusses metamorphosis in animation. Based on Paul Wells&#x2019; 
                <italic toggle="yes">Understanding Animation</italic>, Napier emphasizes the importance of metamorphosis in animation as follows:</p>
            <disp-quote>
                <p>[A]nimation&#x2019;s emphasis on metamorphosis can be seen as the ideal artistic vehicle for expressing the postmodern obsession with fluctuating identity. What animation scholar Paul Wells describes as &#x201c;the primacy of the image and its ability to 
                    <italic toggle="yes">metamorphose</italic> into a completely different image&#x201d; is a function of animation that has powerful resonances with contemporary society and culture (

            </disp-quote>
            <p>Napier&#x2019;s argument connects the ability of animation to metamorphose with changing identities in postmodern Japanese society at the turn of the century. Therefore, she discusses metamorphoses in Japanese animation films and TV programs, such as Tetsuo&#x2019;s collapsing body in 
                <italic toggle="yes">Akira</italic> (&#x014c;tomo Katsuhiro, 1988), the protagonist&#x2019;s transformation to battle form in

                <italic toggle="yes">Ranma 1/2</italic> (1989-1992), the tentacled monster in pornographic animation, and the shape-shifting entities in Miyazaki Hayao&#x2019;s works. Vivian

                <xref ref-type="bibr" rid="ref4">Bukatman (2012)</xref> started their arguments with metamorphoses or the free movement of lines, making Napier&#x2019;s argument common in the English-speaking world.</p>
            <p>Napier&#x2019;s argument inevitably connects with the discussion of &#x201c;plasmaticity&#x201d; in animation. The word &#x201c;plasmaticity&#x201d; was proposed by the Soviet film director and theorist Sergei Eisenstein. He referred to the plastic transformation of Disney film characters of the 1920s into indefinite shapes as &#x201c;plasmatic.&#x201d; Eisenstein appreciated the free-kinetic nature of animation, such as Mickey Mouse piloting the steamboat without permission, being chastised by Captain Pete, and having his torso stretch and contract in ways that would be impossible if he were a human being in 
                <italic toggle="yes">Steamboat Willie</italic> (1928), the world&#x2019;s first talkie animation. Although plasmaticity has been considered a medium specificity of animation, Eisenstein originally explained it by referring to manga-like line-drawn illustrations. He listed illustrations accompanying 
                <italic toggle="yes">Alice in Wonderland</italic> and woodblock prints depicting Japanese yokai &#x2014; supernatural beings in Japanese folklore with necks and noses that stretch and contract &#x2014; as examples of unexpected character deformation (
                <xref ref-type="bibr" rid="ref6">Eisenstein, 2017</xref>, 18-19).</p>
            <p>Unlike Eisenstein, Napier does not simply celebrate the possibility of the transformation as an expression of freedom because for her metamorphosis is deeply related to themes, such as sex, sexuality, and childbirth. In 
                <italic toggle="yes">Ranma 1/2</italic>, the protagonist metamorphoses between male and female; however, the overall story follows the order of the male-female binary. In pornographic anime, metamorphosis is often shown in tentacles sex linked to female ecstasy. After pointing out the connection between metamorphosis and sex and sexuality, Napier discusses &#x201c;abjection&#x201d; in Tetsuo&#x2019;s collapsing body in 
                <italic toggle="yes">Akira</italic> based on Julia Kristeva&#x2019;s argument. Napier describes Tetsuo&#x2019;s transformation as a grotesque birth scene, as follows:</p>
            <disp-quote>
                <p>Tetsuo&#x2019;s transformations can be viewed as a particularly gruesome form of combined primal and birth scenes: The phallic tentacular arm that expands and contracts ultimately seems to lose itself into an oozing feminine pinkness, which in turn becomes a gigantic baby. This horrifying &#x201c;birth scene&#x201d; echoes cinema theorist Barbara Creed&#x2019;s statement that the act of birth is seen as grotesque &#x201c;because the body&#x2019;s surface is no longer closed, smooth, and intact, rather it looks as if it may tear apart, open out, reveal its innermost depths (
                    <xref ref-type="bibr" rid="ref16">Napier, 2005</xref>, 45).&#x201d;</p>
            </disp-quote>
            <p>Compared to this description of Tetsuo&#x2019;s transformation by Napier, Cell&#x2019;s metaphorical birth scene is not grotesque or horrific. Cell seems to easily create his Juniors without the slightest twinge of pain or significant identity change. This paper argues that the ease, paradoxically, exemplifies that the issues discussed by Napier are concealed in 
                <italic toggle="yes">Dragon Ball</italic>, where the characters are metamorphosed and their sexuality is obscured.</p>
            <p>Sexuality, specifically, sexual interest in the female body, is in fact expressed in the adventure part of 
                <italic toggle="yes">Dragon Ball.</italic> In the first volume, Bulma shows substantial nudity. Goku, who had never met a woman before, particularly notices the lack of a penis by tapping the crotch of the female characters. When Goku and Bulma encamp at the very beginning of the story, Goku discovers that Bulma has no penis, which astonishes him more than when fighting a strong enemy (Toriyama, Ch. 2). Yumcha, Goku&#x2019;s rival, a desert bandit in the early stages of the story, has a neurotic reaction whenever he sees Bulma because he is unaccustomed to communicating with women (Toriyama, Ch. 8). Yumcha joins Goku and his friends on their journey to find the Dragon Balls to fulfill his wish to become accustomed to women. The other major early characters, such as pig human Oolong and Goku&#x2019;s master Kame-Sen&#x2019;nin, are portrayed as lustful individuals, willing to stare at women&#x2019;s naked bodies (Toriyama, Chs. 4, 5, 12). The following is an important plot point: when all the Dragon Balls are collected to summon Shen Long, the magical dragon that grants wishes, Oolong cries, &#x201c;Give me a gal&#x2019;s panties,&#x201d; thwarting the villains&#x2019; ambitions for world domination (Toriyama, Ch. 20). Thus, when 
                <italic toggle="yes">Dragon Ball</italic> was an adventure rather than a fighting manga, several references to female bodies as objects of sexual desire were present. Such depictions were not without controversy: although the original series was serialized in a magazine targeting pre-teen to teenage boys in Japan, references to sex and sexuality sparked significant debate in the United States (
                <xref ref-type="bibr" rid="ref2">&#x201c;Viz explains,&#x201d; 2000</xref>; 
                <xref ref-type="bibr" rid="ref1">&#x201c;Maryland School,&#x201d; 2009</xref>).</p>
            <p>However, in the latter half of the series, the focus shifts to muscular men&#x2019;s battles, and the issue of sexuality remains untouched. In 
                <italic toggle="yes">Dragon Ball</italic>, the main characters become couples and have children without depicting romance. Perhaps conforming to the norms of sh&#x014d;nen (boy) manga, the main character, Son Goku, is too ignorant about sex. In this manga world, reproduction takes place by replicating characters without depicting their romance, sexuality, and childbirth. Therefore, in discussing sexuality in

                <title>3.1 Plasmatic flesh: Proliferation of temporal and differential change</title>
                <p>The characters in 
                    <italic toggle="yes">Dragon Ball</italic>, regardless of protagonists or antagonists, transform. The Saiyans, playing an essential role in the story, typically have black hair and eyes. However, when transforming into Super Saiyans, they change to blond hair and blue eyes (Toriyama, Ch. 307). The three major villains who appear in the manga&#x2019;s latter half transform multiple times. The protagonists always find new battle forms and become stronger to defeat the villains, repeating the basic plot pattern of 
                    <italic toggle="yes">Dragon Ball.</italic> The transformation of a character&#x2019;s appearance is a recurring motif and a significant plot driver in 
                    <italic toggle="yes">Dragon Ball.</italic> Therefore, we analyze character transformations in 
                    <italic toggle="yes">Dragon Ball</italic> regarding metamorphosis and plasmaticity and argue that Toriyama&#x2019;s plasmatic motility and fluidity-oriented authorship are embodied by the characters, although this is not always apparent.</p>
                <p>Napier&#x2019;s metamorphosis covers different media-aesthetic qualities because some of the anime, she argues, are based on manga. For example, temporal and differential changes, such as the minute changes in Tetsuo&#x2019;s arm, are in accordance with the medium specificity of animation as a temporal art form. On the contrary, Ranma&#x2019;s sex/gender switching when he/she is exposed to water is not depicted with such temporal and differential change. In the original manga of 
                    <italic toggle="yes">Ranma 1/2</italic>, Ranma&#x2019;s change occurs momentarily between one panel and the next. The experience of reading manga is temporal, but the medium of manga is not accompanied by temporality. Thus, the metamorphosis in 
                    <italic toggle="yes">Ranma 1/2</italic> is different, in terms of media aesthetics, compared with the other cases that Napier discusses.</p>
                <p>Contrarily, Eisenstein&#x2019;s plasmaticity is similar to the temporal and differential changes of Napier&#x2019;s metamorphosis. In his words, plasmaticity is &#x201c;the rejection of the constraint of form &#x2026; freedom from ossification, an ability to take on any form dynamically (
                    <xref ref-type="bibr" rid="ref6">Eisenstein, 2017</xref>, 101).&#x201d; In other words, plasmaticity, ideally, is not bound to a particular form. Thus, Eisenstein cites the flame as an example of plasmaticity because it is constantly changing. However, the Disney works Eisenstein refers to are tied to specific forms: in 
                    <italic toggle="yes">Merbabies</italic> (1938), an octopus arranges its tentacles to look like an elephant. Unlike Ranma&#x2019;s instant and complete change, the octopus has not turned into an elephant. The octopus remains an octopus as a substance, but by changing the shape of its tentacles, it metamorphically appears to the audience as an elephant. Therefore, as Doi Nobuaki argues, providing animation with a doubled perception in the viewer&#x2019;s consciousness is important (
                    <xref ref-type="bibr" rid="ref5">Doi, 2009</xref>, 57-110). According to Eisenstein and Doi&#x2019;s arguments, plasmaticity is defined as the status of the viewer&#x2019;s perception in which expression in animation is not fixed in the particular form represented by the line but is possibly open to another state. The idea of plasmaticity is not necessarily about what is specifically depicted by the ink. However, as Eisenstein cites Disney animated characters from the 1920s, his plasmaticity is almost the same as the temporal and differential changes in Napier&#x2019;s metamorphosis.</p>
                <p>This emphasis on the moving image is shared by another influential framework from which the present study must distinguish itself. Thomas Lamarre&#x2019;s concept of animetism (
                    <xref ref-type="bibr" rid="ref26">Lamarre, 2009</xref>) offers a productive account of the aesthetics of cel animation, distinguishing anime&#x2019;s multiplanar compositing from cinema&#x2019;s depth illusion (cinematism). Lamarre&#x2019;s framework, however, is predicated on the moving image and the technology of layered cel production. The present study, by contrast, addresses the ontological properties of line-drawn characters in manga as a static medium, where, as the following sections argue, plasmaticity is expressed not through temporal movement but through the graphical proliferation of 
                    <italic toggle="yes">kyara</italic> across panels. The two frameworks thus operate on different terrain, even as both foreground the medium-specific properties of Japanese visual culture.</p>
                <p>Returning to the distinction between temporal and non-temporal media, we can reclassify transformation into two categories: 1) temporal and differential change, readily expressed in a temporal art; and 2) instantaneous and complete change, expressed in an art form without temporality. Both types are found in the manga 
                    <italic toggle="yes">Dragon Ball.</italic>
                </p>
                <p>In 
                    <italic toggle="yes">Dragon Ball</italic>, as a non-temporal art of manga, instantaneous and complete transformation is found in many places. Characters, such as Oolong and Pu&#x2019;er, can transform into various creatures and inanimate objects as the story demands. With the Hoi-Poi capsule, structures such as vehicles and dwellings are transformed into small, portable capsules. Further, the main characters transform repeatedly to empower themselves. Saiyans transform into a big monkey form when they see the full moon (Toriyama, Chs. 21, 208, 233, 240). Super Saiyans transform into different fighting forms, such as Super Saiyan 2 and 3, with extended muscles and hair. In addition, all three villains in the work&#x2019;s second half &#x2014; Frieza, Cell, and Majin Buu &#x2014; transform multiple times. Frieza changes his form thrice using his power. Cell transforms from its insect-like shape by absorbing the energy of living organisms through needles in its buttocks. Majin Buu, who is born with a fat body, gets fitter by absorbing others.</p>
                <p>Characters not only transform but also fuse with each other. Piccolo is originally an amnesiac Namekian who evacuated to Earth due to famine. After learning that the Namekians have mysterious powers, Piccolo fuses with a Namekian warrior on the planet Namek and gains significant power-ups (Toriyama, Ch. 295). Later, he regains his power by merging with the God of the Earth and returning to his original self (Toriyama, Ch. 360). In the very last stage of the story, the characters merge, even if they are not Namekians. Goku learned a technique called &#x201c;fusion&#x201d; from the Metamorans, which powers up characters of equal strength by fusing them. Goten and Trunks, Shin and Kibito, and Goku and Vegeta fuse to become new characters to counter Majin Buu (Toriyama, Chs. 480, 501, 503). These examples embody the instantaneous and complete change in character-focused Japanese manga culture.</p>
                <p>At some moments, the transformation or fusion breaks down the character&#x2019;s outline and exposes the temporal and differential moments. The most prominent example is Majin Buu, who becomes the last villain in the main story of the original manga. Toriyama was tired of drawing battles with strong villains in 
                    <italic toggle="yes">Dragon Ball</italic> when he was working on the Buu arc. Majin Buu does not meet the reader&#x2019;s expectations of a muscular, strong opponent and defies such expectations to allow Toriyama to experiment with the pleasures of free-line movement. Majin Buu is born from smoke and has a non-masculine body in the first form, which can separate and transform at will. Even when Majin Buu is shredded into fine pieces, the pieces transform into smaller Majin Buus, and they merge and resurrect in their original form (
                    <xref ref-type="fig" rid="f4">
Figure 4</xref>) (Toriyama, Ch. 468). In other words, Majin Buu&#x2019;s shape-shifting flesh embodies the temporal and differential qualities of metamorphosis and plasmaticity, which can loosen the boundaries of character.</p>

                <p>Both types of transformations appear in the every corner of the manga 
                    <italic toggle="yes">Dragon Ball.</italic> If we examine the entire story according to these two categories of transformation, the instantaneous transformation of Oolong, Pu&#x2019;er, and Hoi-Poi capsule in the early episodes resurfaces as a temporal and differential dynamism of plasmatic flesh in Majin Buu in the final arc. Here, Toriyama&#x2019;s play with the free movement of the line, which cannot be reduced to elements such as stories or battles, is revealed. Apart from the superficial narrative of the clash of men&#x2019;s muscles, Toriyama explored the kinetic freedom of line with ink and paper and his play is actualized as a temporal and differential transformation of the characters.</p>

                <title>3.2 Graphic line-drawn characters as vessels of transformations</title>
                <p>Eisenstein&#x2019;s discussion on fluid plasmaticity focused on the concreteness of the Disney characters. This, ironically, means that the plasmatic fluid character requires a fixed basic form. In this sense, Eisenstein&#x2019;s and Napier&#x2019;s arguments for exalting indefinite mobility and metamorphosis cannot be divorced entirely from the argument on character images.</p>
                <p>Marc Steinberg&#x2019;s discussion of the transmedia proliferation of Japanese anime characters explain this. He argues that relatively simple line drawings of characters allow for the transmedia diffusion of characters in the early history of Media Mix, a Japanese version of transmedia storytelling (
                    <xref ref-type="bibr" rid="ref20">Steinberg, 2012</xref>, 45-64). For example, he has conducted a transmedia analysis of 
                    <italic toggle="yes">Astro Boy</italic> (manga, Tezuka Osamu, 1952-68; TV anime series, 1963-66) and highlighted the phenomenon of the distribution and diffusion of 
                    <italic toggle="yes">Astro Boy</italic> characters beyond the media boundary. His research revealed that flat characters, drawn as line drawings, can permeate people&#x2019;s daily lives using complimentary stickers in chocolate candy boxes. Characters carry what Steinberg calls &#x201c;dynamic immobility (2012, 6),&#x201d; a static nature that conversely enables transmedia motility, and, in this sense, the characters have ontological properties that confine motility. The line-drawn characters are, thus, a prerequisite of the plasmatic transformation in 
                    <italic toggle="yes">Dragon Ball.</italic> Even though the characters&#x2019; appearance changes fluidly in 
                    <italic toggle="yes">Dragon Ball</italic>, the existence of the original characters is assumed.</p>
                <p>Whether it is Napier&#x2019;s metamorphosis or Eisenstein&#x2019;s plasmaticity, 
                    <italic toggle="yes">Dragon Ball</italic> characters are filled with such fluidity. This study emphasizes that a character is a vessel that contains fluidity at various levels. Both Napier and Eisenstein discuss the transformation through specific characters. Eisenstein devotes ample time to describing flames, but flames do not appear in specific works. Therefore, the characters that host such fluidity, whether metamorphosis or plasmaticity, become important.</p>
                <p>Japanese animation and manga studies have discussed the ontological properties of characters depicted in line drawings. The issues of transformation, metamorphosis, and fusion of characters necessarily echo the arguments in these studies. It&#x014d; G&#x014d; distinguished between 
                    <italic toggle="yes">kyara</italic> (proto character), the aspect of human representation in the fictional world of manga as an image drawn with simple lines, and 
                    <italic toggle="yes">kyarakut&#x0101;</italic> (character), the personality behind the 
                    <italic toggle="yes">kyara</italic> images (
                    <xref ref-type="bibr" rid="ref8">It&#x014d;, 2014</xref>, 110-127). Although each image in the individual panels of the manga is distinct, the readers perceive them as a unified personality. In other words, 
                    <italic toggle="yes">kyara</italic> refers to individual images in the individual panels of manga, and 
                    <italic toggle="yes">kyarakut&#x0101;</italic> refers to the coherent personality behind these images that readers assume (
                    <xref ref-type="bibr" rid="ref24">Watabe, 2023</xref>, 98-99). For example, in 
                    <italic toggle="yes">Ranma 1/2</italic>, the male and female Ranma are graphically different, but the readers know that a consistent personality exists behind these different iconographies according to the narrative development. While the 
                    <italic toggle="yes">kyarakut&#x0101;</italic> is important for understanding the story, it is the nature of the 
                    <italic toggle="yes">kyara</italic> that supports the transmedia spread of character culture, as pointed out by Steinberg.</p>

                <title>3.3 Graphical and biological reproduction</title>
                <p>By considering the character as a vessel drawn with lines that confine fluid life, the character theory encounters the issue of reproduction. It&#x014d;&#x2019;s discussion indicates that drawing characters in simple lines allows their graphical reproduction in multiple panels and contexts outside the work (
                    <xref ref-type="bibr" rid="ref8">It&#x014d;, 2014</xref>, 126). The above-mentioned proliferation of Majin Buu symbolically expresses the reproductive nature of 
                    <italic toggle="yes">kyara.</italic> In other words, unlike the temporal art of animation, manga cannot express plasmaticity as a fluctuation of indefinite shape like a burning flame. Instead, manga expresses plasmaticity in the form of a numerical proliferation of 
                    <italic toggle="yes">kyara</italic>, or static image that confines the fluidity. Enclosing plasmaticity in characters, then, causes the theme of dual reproduction &#x2014; the reproduction of images and life &#x2014; in

                <p>Double reproduction is evident in the scene germinating Saibaimen. In the Saiyan arc, Goku&#x2019;s side confronts Vegeta and Nappa, two Saiyans attacking the Earth. Seeing Goku&#x2019;s side as inferior, Vegeta instructs Saibaimen to fight in his place. Saibaimens, meaning &#x201c;cultivation man&#x201d; in Japanese, are improvised combatants that rapidly grow when planted in the ground (
                    <xref ref-type="fig" rid="f5">
Figure 5</xref>). Since Vegeta has the same number of Saibaimen seeds as the number of people on Goku&#x2019;s side, he uses the remaining seeds to create six graphically identical Saibaimen (Toriyama, Ch. 214). The almost instantaneous process of transformation from seed to humanoid embodies plasmatic change. However, such an explosive transformation of matter is fixed in multiple graphically indistinguishable characters.</p>

                <p>Several similar graphically identical individuals are depicted on other occasions. In the Majin Buu arc, Buu can split its irregularly shaped body into multiple graphically identical smaller bodies (see 
                    <xref ref-type="fig" rid="f4">
Figure 4</xref>). Similarly, Gotenks &#x2014; the fused form of Goten and Trunks &#x2014; uses the Ghost Kamikaze Attack technique to create 10 self-explosive ghosts with the same Gotenks head on an irregularly shaped body (Toriyama, Ch. 491). These graphically identical duplicates are also found in the Tien Shinhan, who splits into four bodies (Toriyama, Ch. 183), and seven Cell Juniors. Cell&#x2019;s &#x201c;delivery&#x201d; explicitly connects the graphic reproduction of line-drawn images and reproduction as an organism.</p>
                <p>Piccolo also expresses dual reproduction. After being beaten by Goku, King Piccolo used all his remaining power to spit an egg (Toriyama, Ch. 161). The egg produced a juvenile that resembled the Demon King, who later took the pseudo-name Majunia when participating in the World Martial Arts Tournament (Toriyama, Ch. 167). After the tournament, Goku and his fellows simply called him Piccolo. King Piccolo was originally an evil part separated from the God of Earth. However, Piccolo, born from the Demon King, later merged with the God of Earth. Thus, the story logically treats King Piccolo and Piccolo (Majunia) as the same character. Piccolo&#x2019;s fusion with the God of Earth after fusing with Nail shows that fusion does not change Piccolo&#x2019;s identity at all. The storyline produces multiple Piccolo characters with nearly identical images.</p>
                <p>In 
                    <italic toggle="yes">Dragon Ball</italic>, the transformation and fusion of characters exemplify Toriyama&#x2019;s play with free lines. In other words, the kinetic freedom of lines is anchored in the line-drawn characters. The characters drawn in lines are indeed a foundation and a condition that generates fluidity, leading to the graphical reproduction of characters. Characters&#x2019; graphical replication in Toriyama&#x2019;s authorship is, thus, potentially connected to narrative-intrinsic biological reproduction. Here, the issues of fear of reproduction and childbirth that Napier discussed re-emerge.</p>

                <title>3.4 Abjection of sexuality</title>
                <p>Initially, sexuality was frequently specified in 
                    <italic toggle="yes">Dragon Ball.</italic> However, as the manga series became increasingly about battles, references to female bodies as objects of sexual desire almost disappeared, and biological reproduction was foregrounded. The main male characters on the protagonist&#x2019;s side, Goku, Vegeta, and Krillin, married and had children without the depiction of romance, family life, and delivery. Toriyama&#x2019;s dislike of the romantic comedy genre (
                    <xref ref-type="bibr" rid="ref22">Toriyama, 1984</xref>, 130) and the fact that the series was published in an adolescent boy magazine explains the near-complete absence of romance and family life. The proliferation and reproduction of human characters are instead imprinted on various levels in Toriyama&#x2019;s drawings.</p>
                <p>The depiction of Android 18 is a good example of reproduction through a body that lacks sexuality. In the Android arc, Cell is an artificial life made entirely of artificially created organisms, while Androids 17 and 18 are human beings enhanced with artificial organic parts. Toriyama represented Cell and the two Androids as beings of flesh and blood, rather than completely mechanical beings, so that Cell could absorb the two Androids to gain power. Later, Cell ejects Android 18 when Cell is significantly damaged and cannot keep her within him. The ejection of Android 18 is not depicted or foregrounded as a grotesque childbirth in the battle manga context. Such a metaphorical childbirth scene is actualized as a real childbirth lacking specific description in the main plot. Android 18&#x2019;s reproductive organs and functions, which are unnecessary for fight, mysteriously remain as they are even after she is converted to an Android. She marries Krillin, one of Goku&#x2019;s companions, and gives birth to a daughter (Toriyama, Ch. 426). A romantic relationship leading up to the birth of the daughter is not depicted at all, as if 
                    <italic toggle="yes">Dragon Ball</italic> is trying to &#x201c;abject&#x201d; the sexuality and childbirth as a result of romance by making battle the central theme of the manga.</p>
                <p>Even heterosexuality, such as references to female bodies as objects of sexual desire, is not represented in 
                    <italic toggle="yes">Dragon Ball</italic> after the transition to the battle genre. Instead, biological reproduction is presented, which is cohesive with the existence of Namekians. Piccolo dies in a fight with Vegeta and Nappa, and the Dragon Ball disappears. The God of Earth &#x2014; the creator of the Dragon Ball &#x2014; also dies with its counterpart, Piccolo, the evil part of the God of Earth. However, a conversation between Vegeta and Nappa reveals that Piccolo is a Namekian, and the protagonists travel to the Namek planet to resurrect the dead with the power of another Dragon Ball that the Namekians possess. They discover that the Namekians, threatened with extinction, have recovered their population to about 100. The only surviving eldest has given birth to all the Namekians, who live in several settlements around the elders. The word &#x201c;Namek&#x201d; is derived from the Japanese word &#x201c;
                    <italic toggle="yes">namekuji</italic>,&#x201d; which means &#x201c;slug,&#x201d; and the main Namekian characters, Dende and Nail, are named after &#x201c;
                    <italic toggle="yes">denden</italic>mushi,&#x201d; another Japanese word for slug, and the English word &#x201c;snail,&#x201d; respectively. Namekians are hermaphrodites and do not feel love in the manner that humans do.</p>
                <p>The &#x201c;delivery&#x201d; of Cell is not exceptional in 
                    <italic toggle="yes">Dragon Ball</italic> manga. At the beginning of the Buu arc, Android 18 gives birth to a child of Krillin, repeating the motif of childbirth (Toriyama, Ch. 426). Goku and Chichi, and Vegeta and Bulma also have children, but the manga does not depict their romance. In this respect, the Namekians, who reproduce monogenetically, not heterosexually, have ontological characteristics similar to graphically reproducing line-drawn characters. As symbolized in Cell&#x2019;s &#x201c;delivery,&#x201d; symbolic and graphic characters are transformed, fused, and replicated considering plasmatic movement from within. Thus, 
                    <italic toggle="yes">Dragon Ball</italic>, except for the initial adventure part, presents graphic and biological reproduction without sex.</p>
                <p>Kristeva&#x2019;s abjection that Napier indicates for Japanese animation in the 1990s seems to operate in the work to make the issues more invisible in 
                    <italic toggle="yes">Dragon Ball.</italic> Abjection refers to a reaction in which one tries to dismiss the horrifying yet familiar thing approaching one&#x2019;s body. It is an ambivalent feeling expressing such a state or action, with the nuance of being horrified at the idea of exposing oneself to it. In 
                    <italic toggle="yes">Dragon Ball</italic>, Cell&#x2019;s &#x201c;delivery&#x201d; and the multiplication of flesh in the form of Saibaimen are masked in their horror by being framed in the vessel of the character: what is horrific is the unknown powerful enemies, not the reproduction of life. Through the proliferating characters, the readers can appreciate a double reproduction while remaining oblivious to the horror of childbirth. This is exemplified by the fact that the protagonist, Goku, is utterly unaware of sexual issues throughout the story.</p>
                <p>This argument recalls that plasmaticity is related to forgetting for Eisenstein. Theodor Adorno and Max Horkheimer believed that Disney films turned people away from real problems in a capitalist society, as evidenced by Donald Duck being sadistically smashed (
                    <xref ref-type="bibr" rid="ref3">Adorno and Horkheimer, 2002</xref>, 110-111). Contrarily, Eisenstein believed that the audience of Disney films would obliterate the capitalist social system but provide a fleeting release (
                    <xref ref-type="bibr" rid="ref6">Eisenstein, 2017</xref>, 19). Oblivion is the opportunity to forget the world&#x2019;s de facto order and be open to the possibilities of an alternative. The fluidity and forgetfulness in Disney films acclimated people to capitalism, as per Adorno and Horkheimer, and were a brief release from capitalism for Eisenstein. Discussing characters in Japanese anime and manga studies within this context can allow us to reinterpret the issues of fluidity and forgetting in 
                    <italic toggle="yes">Dragon Ball</italic> as sexuality. In the manga, the free line proliferates and has a fluid presence as plasmatic flesh. However, this plasmatic flesh is to be actualized on the vessel of the characters to replicate the characters as icons. The reproduction of the characters is expressed as devoid of concrete rawness related to sex, sexuality, and childbirth. Thus, in the sexually oblivious world of 
                    <italic toggle="yes">Dragon Ball</italic>, a masculine struggle between men is depicted on the surface, with a fluid world of endless dual reproduction behind it.</p>

Considering reproduction as a matter of life, there is practically no death because the power of the Dragon Balls can resurrect the dead. The dead characters have angel rings and are trained in martial arts under supernatural beings in the afterlife. They even appear in the real world marked with angel rings for the story&#x2019;s development. The characters do not consider death seriously. Goku and other characters repeatedly say, &#x201c;They will come back to life because we have Dragon Balls (Toriyama, Ch. 473).&#x201d;

                <p>Consequently, is there no death in this world of 
                    <italic toggle="yes">Dragon Ball</italic>? &#x014c;tsuka Eiji argues that manga characters, being mere line drawings, are theoretically invulnerable, similar to Mickey Mouse with a flexible torso in 
                    <italic toggle="yes">Steamboat Willie.</italic> According to &#x014c;tsuka, Tezuka Osamu&#x2019;s depiction of a character who was shot and injured by machine gun fire in his pre-debut study, &#x201c;Until the Day of Victory (Sh&#x014d;ri no Hi Made)&#x201d; introduced the idea of vulnerable characters into manga (
                    <xref ref-type="bibr" rid="ref17">&#x014c;tsuka, 2009</xref>, 133-145). &#x014c;tsuka introduces the realism of the character&#x2019;s vulnerability as the ethical starting point of postwar manga. Following &#x014c;tsuka&#x2019;s perspective, the issue of character immortality in 
                    <italic toggle="yes">Dragon Ball</italic> can be tied to Toriyama&#x2019;s preference for American culture. 
                    <italic toggle="yes">Dr. Slump</italic>, Toriyama&#x2019;s other manga, which gained popularity before 
                    <italic toggle="yes">Dragon Ball</italic>, refers to a lot of American popular culture. The proliferation of lines with motility in 
                    <italic toggle="yes">Dragon Ball</italic> appears to be an obliteration of death in Americanized postwar Japan.</p>
                <p>Catherine Malabou&#x2019;s discussion of &#x201c;plasticity&#x201d; provides insight into the issue of lack of death in 
                    <italic toggle="yes">Dragon Ball</italic> and, by extension, &#x014c;tsuka&#x2019;s aforementioned argument. The French philosopher used the concept of &#x201c;plasticity&#x201d; to reinterpret Hegel&#x2019;s dialectic. In Hegel, as read by Koj&#x00e8;ve and Heidegger, temporality is nullified, and the future is absent. However, by introducing the concept of plasticity, which can both gift and receive forms, it re-finds the self as open to the contingency of the future (
                    <xref ref-type="bibr" rid="ref12">Malabou, 2005</xref>, 5-20).</p>
                <p>What Malabou refers to here as &#x201c;plasticity&#x201d; is different from Eisenstein&#x2019;s plasmaticity. Plasticity embraces the irreversibility of change and is essentially different from plasmaticity, the idea of not being fixed in a particular form. Malabou applies the concept of plasticity to analyze cinematic and literary works that exemplify this. For instance, Marguerite Duras who &#x201c;was young for only a very short time (
                    <xref ref-type="bibr" rid="ref13">Malabou, 2012</xref>, 56)&#x201d; and finds herself decisively transformed in her autobiographical novel, 
                    <italic toggle="yes">The Lover</italic> (1984), and the female protagonist in Alain Resnais&#x2019; 
                    <italic toggle="yes">Hiroshima Mon Amour</italic> (1959), who has been thrown out of her hometown because of her romance with a Nazi officer during WWII, revive their memories and start a new life. Thus, the plasticity of Malabou is about the decisive and irreversible transformation of human beings and is not directly related to the free dynamism of line drawings in animation.</p>
                <p>Malabou&#x2019;s concept of &#x201c;plasticity&#x201d; is applicable to analyzing manga when she finds a third meaning in the idea: &#x201c;form blasting,&#x201d; which is different to the gifting and acceptance of the form. With the invention of the plastic bomb in the 20
                    <sup>th</sup> century, the word &#x201c;plasticity&#x201d; was given a third meaning &#x2014; the instantaneous destruction or annihilation of forms (
                    <xref ref-type="bibr" rid="ref14">Malabou, 2009</xref>, 70-77). The meaning of &#x201c;plasticity&#x201d; as a destruction of form is quite different from the ability of the medium of plastic art to receive form, such as viscosity or marble, or the ability to provide form, such as education or biological adaptation. In this third sense, the form is destroyed instantly, causing explosive change.</p>
                <p>This third sense of plasticity is expressed in 
                    <italic toggle="yes">Dragon Ball</italic> in the form of the energy waves emitted by the characters, as represented by Kamehameha. In the early story, Goku&#x2019;s master, Kame-Sen&#x2019;nin, uses a 
                    <italic toggle="yes">Kamehameha</italic>, which releases latent energy from both hands, to extinguish the flames &#x2014; the very object that Eisenstein considered to be plasmatic &#x2014;burning the castle of the Ox King (
                    <xref ref-type="fig" rid="f6">
Figure 6</xref>) (Toriyama, Ch. 14). Following the same, the characters in the film perform techniques that emit various energy waves to annihilate their enemies. The characters engage in physical combat and attack by releasing energy waves, mainly from their hands. This energy wave annihilates the three main villains. For instance, Cell and Buu embody plasmatic motility to revive themselves from a single cell and cannot be destroyed in hand-to-hand combat. Goku&#x2019;s son Gohan releases the 
                    <italic toggle="yes">Kamehameha</italic> that extinguishes Cell to the last piece (Toriyama, Ch. 416). In the case of Buu, Goku releases 
                    <italic toggle="yes">Genkidama</italic>, which destroys Buu entirely (Toriyama, Ch. 516). Regardless of the intra-narrative life and death of the characters, this light of annihilation can destroy the plasmatic movement and proliferation of cells.</p>

                <p>Light poses a real crisis for the characters. The glowing light of the annihilating energy wave is technically an absence of ink on paper. Thus, the lack of ink imparts death to the characters, which graphically proliferate with the plasmatic flesh movement, exemplifying the medium specificity of manga as ink on paper.</p>
                <p>The pure white glow is the counterpart of light when considering animation as a medium of light, which is analogous to live-action film. The unfolding of the characters&#x2019; deaths by light positions 
                    <italic toggle="yes">Dragon Ball</italic> in the genealogy of Japanese popular culture. Several examples in Japanese popular animation series show that light not only deletes an organism but also causes its ontological annihilation. For instance, the great explosion of Neo-Tokyo caused by the psychic Akira&#x2019;s uncontrolled abilities in 
                    <italic toggle="yes">Akira</italic>, the vaporization of human bodies by beam rifles, mega-particle cannons, and nuclear explosions in the 
                    <italic toggle="yes">Gundam</italic> series (1979-), and the heat and destructive rays spewed by giant monsters in the Godzilla series (1954-) utilize light as a means to give characters death. Many post-1980 celluloid (cel) anime, like 
                    <italic toggle="yes">Dragon Ball</italic> and 
                    <italic toggle="yes">Dragon Ball Z</italic>, utilized &#x201c;transmitted light (
                    <italic toggle="yes">t&#x014d;kak&#x014d;</italic>).&#x201d; When creators sought to create a striking light image, they started by producing cel images with certain masked areas. These masked cels were then exposed to a strong backlight. By multiple-exposing the strong light image with normally filmed animated images, they created anime that had a brighter glow than those using paint to express light (
                    <xref ref-type="bibr" rid="ref7">Goshima, 2017</xref>). In this sense, celluloid anime practically used light to bring annihilation to the medium of anime.</p>
                <p>These scenes of catastrophic destruction are inevitably associated with the atomic bomb explosion in Japanese cultural history. While discussing the &#x201c;invisible light&#x201d; throughout the modern history of Japanese culture, Akira Lippit discusses the atomic bomb as a &#x201c;violent photography directly onto the surfaces of the human body&#x201d; by stating the following:</p>
                <disp-quote>
                    <p>The catastrophic flashes followed by a dense darkness transformed Hiroshima and Nagasaki into photographic laboratories, leaving countless traces of photographic and skiagraphic imprints on the landscape, on organic and nonorganic bodies alike. The world a camera, everything in it photographed. Total visibility for an instant and in an instant everything rendered photographic, ecstatic, to use Willem de Kooning&#x2019;s expression, inside out. The grotesque shadows and stains &#x2014; graphic effects of the lacerating heat and penetrating light &#x2014; the only remnants of a virtual annihilation. (
                        <xref ref-type="bibr" rid="ref11">Lippit, 2005</xref>, 109)</p>
                </disp-quote>
                <p>Lippit considers the traces of organic material baked by the light and heat of the atomic bomb as the photographic effect. His argument parallels the characteristics of 
                    <italic toggle="yes">Dragon Ball</italic> that this paper has discussed so far. The movement of the lines drawn by the ink gains characters as vessels and multiplies, but the light expressed by the lack of ink demolishes them. The light that causes immense destruction obliterates the problem of flesh, which is forgotten in Japanese popular culture, just as heterosexual reproduction and childbirth are concealed in 
                    <italic toggle="yes">Dragon Ball.</italic>
                </p>
                <p>By comparing this understanding with &#x014c;tsuka&#x2019;s ethical critical position already discussed, 
                    <italic toggle="yes">Dragon Ball</italic> can be seen as one of the turning points in postwar Japanese manga culture. From the perspective of &#x014c;tsuka, who begins his historical account of postwar Japanese manga, &#x201c;vulnerable body&#x201d; inescapably leads to the damage caused by the atomic bomb in the Japanese context. Hence, the manga 
                    <italic toggle="yes">Barefoot Gen</italic> (Nakazawa Keiji, 1973-87), which depicted many victims of the atomic bomb explosion over Hiroshima whose skin does not regenerate and whose bodies melt down due to radiation, would be the ideal postwar Japanese manga. In

            <p>This study places 
                <italic toggle="yes">Dragon Ball</italic> within a theoretical trend in anime and manga studies that emphasizes and analyzes the kinetic nature of the line. Drawing on the work of Susan Napier and Sergei Eisenstein, the study discusses the presence of a tendency toward a certain extent of freedom of line motility in 
                <italic toggle="yes">Dragon Ball</italic>. However, the mobility shown in the manga does not always open the audience&#x2019;s perception to the possibility of other forms, as Eisenstein argues, but rather represents limited freedom within the confines of the graphic characters. Being trapped in this frame of character creates a double reproducibility in 
                <italic toggle="yes">Dragon Ball</italic>. The motility of the line is absorbed into the framework of the characters and aims to multiply. In the world of 
                <italic toggle="yes">Dragon Ball</italic>, which avoids facing up to sex and sexuality, the proliferation of lines is represented as graphic reproductions of characters. Therefore, the sexual elements that Napier emphasized are suppressed and obscured in 
                <italic toggle="yes">Dragon Ball</italic>. This study contends that through this double reproducibility, characters multiply to the extent that the death of characters is nullified. With energy waves, like 
                <italic toggle="yes">Kamehameha</italic>, represented by the lack of ink, protagonists can kill the major villains who have plasmatic bodies that can be resurrected even from a single cell. Only the light produced by this lack of ink can annihilate the characters. The annihilation of prolific characters through light replicates the image of the atomic bomb explosion in Japanese popular culture.</p>
            <p>The title of this paper, &#x201c;Crush of Plasmatic Flesh,&#x201d; is intended to enact this double logic. &#x201c;Crush&#x201d; carries two meanings simultaneously: the violent collision of bodies in battle, and the unspoken romantic longing that 
                <italic toggle="yes">Dragon Ball</italic> systematically displaces and represses. Just as the manga conceals the horror of biological reproduction beneath the spectacle of masculine combat, the title conceals its erotic connotation beneath the surface of physical destruction&#x2014;performing, in miniature, the same act of abjection that the paper describes. To read this double meaning is already to practice the methodology the paper proposes.</p>
            <p>That methodology&#x2014;attending to what is suppressed beneath the surface of the visual text, and tracking how the medium-specific properties of ink and line encode cultural logics that the narrative works to conceal&#x2014;is not limited to 
                <italic toggle="yes">Dragon Ball</italic>. It offers a transferable framework for reading other manga and anime in which bodily transformation and destruction are central motifs, and for understanding more broadly how Japanese popular visual culture processes the historical trauma of the postwar period.</p>

            <p>This paper includes images from the digital editions of Akira Toriyama&#x2019;s 
                <italic toggle="yes">Dragon Ball</italic> (Shueisha) and Keiji Nakazawa&#x2019;s 
                <italic toggle="yes">Barefoot Gen</italic> (Choubunsha). These citations comply with the conditions for quotation as stipulated in Article 32 of the Japanese Copyright Law. When noting the source of an event in the 
                <italic toggle="yes">Dragon Ball</italic> story, the manga chapter number was considered. This is because the chapters in each volume differ in Japan between the 42-volume manga in the standard edition and the 34-volume complete edition. In the English-speaking world, the first 16 volumes of the 42-volume Japanese series have been published in book form as 
                <italic toggle="yes">Dragon Ball</italic>, and the latter 26 volumes as 
                <italic toggle="yes">Dragon Ball Z</italic>. To avoid confusion caused by such differences between versions, we have decided to indicate chapter numbers.</p>

        <body>
            <p>The present article is an exciting new contribution to both scholarship on 
                <italic>Dragonball </italic>and to manga theory. It examines the use and absence of line as a semiotic tool that denotes the fluidity and plasticity of bodies, seemingly presented as hard-edged, defined, and masculine, but actually frequently transforming, merging, splitting, and reproducing themselves. Ingeniously, the author points out that light, depicted as the absence of ink, is what destroys these bodies and stops their plasmatic reproduction.</p>
            <p> The article is a welcome contribution to the field, and its analysis is intriguing. I only have a couple of suggestions: 
                <list list-type="order">
                    <list-item>
                        <p>The article argues that reproduction happens in 
                            <italic>Dragonball </italic>without depiction of sexuality, romance, delivery, or &#x201c;family life.&#x201d; (Section 3.4) While the point about lack of sexuality and romance is well taken, in fact the series does depict family life, even if it is peripheral to the battles. This is significant because the family life rendered in 
                            <italic>Dragonball</italic> transforms strong female warriors into mothers and housewives; e.g., Chichi transforms from a capable fighter into an &#x201c;education mama,&#x201d; Android 18 transforms from a terrifying and powerful villain into a wife and mother who, notably, loses to the pathetic Mr. Satan to support the household finances. In the spinoff material, Videl also becomes devoted to motherhood. In other words, while there might be a lack of sexuality or romance, the gendered family (the social site of reproduction) and its roles for women are still very much present and powerful, which the article might acknowledge.</p>
                    </list-item>
                    <list-item>
                        <p>The article mostly treats 
                            <italic>Dragonball </italic>as a case study for examining manga line, ink, and the lack thereof. This is a fantastic analysis, but it would be nice if the article could also clearly state, perhaps just in the conclusion, how this analysis challenges or transforms our reading of 
                            <italic>Dragonball</italic> itself.</p>
                    </list-item>
                </list> Despite these minor suggestions, the article is analytically rigorous, participates in the ongoing scholarly discourse, and is a welcome and timely contribution to the field.</p>
            <p>Is the work clearly and accurately presented and does it cite the current literature?</p>
            <p>Yes</p>
            <p>If applicable, is the statistical analysis and its interpretation appropriate?</p>
            <p>Not applicable</p>
            <p>Are all the source data underlying the results available to ensure full reproducibility?</p>
            <p>No source data required</p>
            <p>Is the study design appropriate and is the work technically sound?</p>
            <p>Yes</p>
            <p>Are the conclusions drawn adequately supported by the results?</p>
            <p>Yes</p>
            <p>Are sufficient details of methods and analysis provided to allow replication by others?</p>
            <p>Yes</p>
            <p>Reviewer Expertise:</p>
            <p>Modern Japanese literature, manga, anime, Japanese pop culture, postmodernism.</p>
            <p>I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard.</p>

        <body>
            <p>This article presents an original and theoretically ambitious analysis of 
                <italic>Dragon Ball</italic>, examining the relationship between graphical transformation, biological reproduction, and abjection through the frameworks of Susan Napier, Sergei Eisenstein, and Japanese manga studies. Rather than approaching 
                <italic>Dragon Ball</italic> primarily as a narrative or cultural phenomenon, the author focuses on the medium-specific properties of manga itself, arguing that the fluidity of ink lines and the reproduction of graphical characters form the basis for a distinctive aesthetic of transformation. The article further proposes that this graphical reproduction parallels biological reproduction while simultaneously suppressing explicit representations of sexuality, culminating in an insightful discussion of light, annihilation, and postwar Japanese visual culture.</p>
            <p> One of the major strengths of the paper is its interdisciplinary engagement with animation theory, manga studies, philosophy, and media aesthetics. The author successfully combines established theoretical perspectives with close readings of 
                <italic>Dragon Ball</italic>, producing an interpretation that is both original and intellectually stimulating. The discussion of plasmaticity, kyara theory, and graphical reproduction is particularly compelling, and the article offers a valuable contribution to scholarship on manga and Japanese visual culture.</p>
            <p> The manuscript is also well grounded in the primary source material. Numerous examples from 
                <italic>Dragon Ball</italic> effectively support the theoretical claims, and the revised version has further strengthened these connections through additional references and clarifications. The conclusion clearly articulates the broader applicability of the proposed analytical framework beyond 
                <italic>Dragon Ball</italic>, increasing the paper's relevance for future research in anime and manga studies.</p>
            <p> The manuscript is generally well written and logically structured. The progression from theoretical foundations to textual analysis and finally to broader cultural implications is coherent and easy to follow despite the conceptual complexity of the subject.</p>
            <p> I have only a few minor suggestions that could further strengthen the manuscript: 
                <list list-type="bullet">
                    <list-item>
                        <p>Some of the theoretical sections are particularly dense and introduce multiple conceptual frameworks in rapid succession. Adding a few brief transitional sentences summarizing how each framework builds upon the previous discussion would improve readability for readers who are less familiar with anime and manga theory.</p>
                    </list-item>
                    <list-item>
                        <p>The connection between the concepts of plasmaticity, reproduction, and abjection is convincing, but occasionally the transitions between these concepts could be made slightly more explicit, particularly when moving from medium-specific analysis to broader cultural interpretations.</p>
                    </list-item>
                    <list-item>
                        <p>The discussion of postwar memory and the atomic bomb imagery is thought-provoking. A brief acknowledgment that this represents one interpretative framework among several possible readings would further reinforce the scholarly balance of the argument.</p>
                    </list-item>
                </list> These suggestions are intended only to improve clarity and accessibility. They do not affect the originality, methodological soundness, or scholarly value of the manuscript.</p>
            <p> Overall, this is a thoughtful, innovative, and well-researched contribution to manga and anime studies. It advances an original theoretical perspective on 
                <italic>Dragon Ball</italic> while engaging critically with existing scholarship. I believe the manuscript is scientifically sound and suitable for indexing after minor revisions addressing the points above.</p>
            <p>Is the work clearly and accurately presented and does it cite the current literature?</p>
            <p>Yes</p>
            <p>If applicable, is the statistical analysis and its interpretation appropriate?</p>
            <p>Not applicable</p>
            <p>Are all the source data underlying the results available to ensure full reproducibility?</p>
            <p>No source data required</p>
            <p>Is the study design appropriate and is the work technically sound?</p>
            <p>Yes</p>
            <p>Are the conclusions drawn adequately supported by the results?</p>
            <p>Yes</p>
            <p>Are sufficient details of methods and analysis provided to allow replication by others?</p>
            <p>Partly</p>
            <p>Reviewer Expertise:</p>
            <p>Japanese Anime, Religion, Interreligious and Intercultural Communication, Philosophy.</p>
            <p>I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard.</p>

                <bold>Overall Assessment</bold>
            </p>
            <p> This article presents a critical and nuanced analysis of the mechanisms of reproduction and character transformation in Dragon Ball through the lens of animation theory and visual cultural studies. By employing Eisenstein&#x2019;s concept of plasmaticity, Napier&#x2019;s metamorphosis, and Kristeva&#x2019;s theory of abjection, the author successfully frames Dragon Ball as a text that not only depicts physical battles but also explores the tension between fluid identity and absolute destruction.</p>
            <p> </p>
            <p> The intellectual strength of this paper lies in its ability to connect the aesthetics of manga as a medium with broader cultural and historical dimensions, particularly in referencing post-war Japan and the visual legacy of the atomic bomb. Thus, this article has the potential to become a significant reference in manga and anime studies, as well as in broader discourses on visual culture and media theory.</p>
            <p> </p>
            <p> However, there are certain methodological and analytical aspects that require further elaboration and justification to elevate the arguments to a higher level of academic rigor.</p>
            <p> </p>
            <p> 
                <bold>Strengths of the Article</bold>
            </p>
            <p> 1. Rich and Interdisciplinary Theoretical Framework</p>
            <p> The author integrates theories from diverse fields&#x2014;animation studies, semiotics, Japanese cultural studies, and psychoanalytic theory&#x2014;in a complex yet structured manner. The use of Eisenstein&#x2019;s plasmaticity and the application of Kristeva&#x2019;s abjection theory to&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;demonstrate the author&#x2019;s ability to conduct a deep reading of visual texts.</p>
            <p> </p>
            <p> 2.&#x00a0;In-Depth Aesthetic and Narrative Analysis</p>
            <p> This article offers a fresh interpretation of&#x00a0;
                <italic>Dragon Ball</italic>, shifting the focus from conventional readings that view it as an action manga to a conceptual mapping of dual reproduction. By linking character transformations to the fluidity of ink in manga, the author successfully illustrates how the technical aspects of the medium shape cultural and ideological meanings.</p>
            <p> </p>
            <p> 3.Contextualization within Japanese Cultural History</p>
            <p> One of the greatest strengths of this paper is its ability to connect motifs of destruction and light in&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;with Japan&#x2019;s visual history, particularly in the shadow of post-Hiroshima. The discussion of energy explosions in anime and manga as echoes of wartime tragedies adds a broader dimension to the discourse, making the article more relevant to contemporary Japanese cultural studies.</p>
            <p> </p>
            <p> 
                <bold>Weaknesses and Suggestions for Improvement</bold>
            </p>
            <p> 1.&#x00a0;Lack of Empirical Data or Case Studies Supporting Claims.</p>
            <p> While the article is rich in theoretical analysis, some claims regarding audience reception and cultural implications are made without sufficient empirical support. For example, the argument that&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;reflects Japan&#x2019;s collective fear of fluid identity and post-war destruction requires additional references from audience reception studies or visual cultural history.</p>
            <p> Suggestion
                <bold>:</bold>
            </p>
            <p> The author is advised to include reception studies, fan interviews, or at least reference existing research discussing the reception of&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;in Japan and globally to strengthen the validity of their arguments.</p>
            <p> </p>
            <p> 2.&#x00a0;Lack of Comparative Analysis with Other Anime and Manga Texts.</p>
            <p> The article discusses&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;in depth but does not sufficiently compare it with other works featuring similar themes of character transformation, such as&#x00a0;
                <italic>Akira</italic>,&#x00a0;
                <italic>Neon Genesis Evangelion</italic>, or&#x00a0;
                <italic>Parasyte</italic>. Such comparisons could provide a more critical perspective on how&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;differs from or aligns with narratives of transformation and destruction in anime culture.</p>
            <p> Suggestion:</p>
            <p> Adding comparisons with other manga or anime that also focus on bodily and identity transformations would reinforce the argument that the phenomena discussed in this article are not isolated but part of a larger trend in Japanese visual culture.</p>
            <p> </p>
            <p> 3.&#x00a0;Imbalance Between Visual and Narrative Analysis.</p>
            <p> Although the article emphasizes the importance of manga aesthetics in shaping meaning, discussions on visual aspects are often overshadowed by more abstract theoretical analysis. For instance, references to specific manga panels in&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;are limited, weakening the reader&#x2019;s ability to directly observe how the described phenomena are translated into the formal aspects of the manga itself.</p>
            <p> Suggestion:</p>
            <p> Incorporating more close readings of specific panels in&#x00a0;
                <italic>Dragon Ball</italic>, with discussions on how linework, negative space, and panel composition contribute to meaning-making, would strengthen the article&#x2019;s central arguments.</p>
            <p> </p>
            <p> 4.&#x00a0;Overemphasis on Sexuality While Neglecting Masculinity Issues.</p>
            <p> The article discusses how&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;erases sexuality and replaces it with asexual and mechanistic reproduction. However, the aspect of masculinity highlighted in the narrative of muscular male fighters is not explored in sufficient depth.</p>
            <p> Suggestion:</p>
            <p> The author could expand the analysis by linking masculinity in&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;to theories of hyper-masculinity in Japanese popular culture, as discussed by scholars such as Sharon Kinsella or Patrick Galbraith. This would create a more balanced analysis, moving beyond the erasure of sexuality to examine how&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;shapes masculine identities in anime culture.</p>
            <p> </p>
            <p> 
                <bold>Conclusion and Peer Review Decision</bold>
            </p>
            <p> Overall, this article is a valuable contribution to anime and manga studies, offering an innovative perspective on&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;as a complex visual text. The theoretical approach is robust, and the discussion of dual reproduction and the erasure of sexuality is a discourse that deserves further attention in Japanese cultural studies.</p>
            <p> However, certain methodological and analytical aspects could be improved to elevate the article to a higher academic standard:</p>
            <p> -&#x00a0;Including empirical data or reception studies to support cultural arguments.</p>
            <p> - Adding comparisons with other manga or anime with similar themes.</p>
            <p> - Strengthening visual analysis with more close readings of manga panels.</p>
            <p> - Expanding the discussion on masculinity to balance the analysis of sexuality.</p>
            <p> </p>
            <p> 
                <bold>Peer Review Decision:&#x00a0;</bold>
                <bold>Accepted with Revisions</bold>
            </p>
            <p> This paper has a strong foundation and is worthy of publication after addressing the suggested improvements. With reinforced empirical evidence, broader comparative analysis, and more detailed visual references, this article has the potential to become a key reference in anime and manga studies within the context of Japanese visual culture.</p>
            <p> </p>
            <p> Here are my comments regarding the questions above:</p>
            <p> </p>
            <p> 1. Is the work clearly and accurately presented, and does it cite current literature?</p>
            <p> Answer:&#x00a0;Partly</p>
            <p> 
                <bold>Comment:</bold>&#x00a0;The article is written in a deeply theoretical and philosophical style, but its presentation can sometimes be convoluted and difficult for non-specialists in cultural theory or body philosophy to follow. Key concepts such as "abjection," "dual reproduction," and "plasmaticness" are discussed with references to major figures like Kristeva and Eisenstein, but there is a lack of engagement with contemporary literature&#x2014;particularly in current manga studies or modern narrative theory. Some references are also rather dated and do not reflect the latest discourse in the field.</p>
            <p> </p>
            <p> 2. Is the study design appropriate, and is the work technically sound?</p>
            <p> Answer
                <bold>:</bold>&#x00a0;Partly</p>
            <p> 
                <bold>Comment:</bold>&#x00a0;This study is more conceptual than empirical or quantitative, so a discourse analysis/visual criticism approach is appropriate. However, the conceptual framework is not systematically explained, making some arguments appear academically unsound in terms of analytical rigor. The hermeneutic approach to manga like&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;is valid but could be strengthened with a more explicit and consistent theoretical framework.</p>
            <p> </p>
            <p> 3. Are sufficient details of methods and analysis provided to allow replication by others?</p>
            <p> Answer
                <bold>:</bold>&#x00a0;Partly</p>
            <p> 
                <bold>Comment:</bold>&#x00a0;Since the article is theoretical and discourse-based, it does not involve empirical methods that can be replicated. However, it lacks clear methodological explanations for visual analysis&#x2014;such as how manga panels were selected, how conceptual categorizations were made, or how the text was semiotically coded. This makes it difficult for other researchers to replicate or expand upon the study.</p>
            <p> </p>
            <p> 4. If applicable, is the statistical analysis and its interpretation appropriate?</p>
            <p> Answer
                <bold>:</bold>&#x00a0;Not applicable</p>
            <p> 
                <bold>Comment:</bold>&#x00a0;The article does not involve any statistical analysis. It is interpretive and philosophical in nature.</p>
            <p> </p>
            <p> 5. Are all the source data underlying the results available to ensure full reproducibility?</p>
            <p> Answer
                <bold>:</bold>&#x00a0;Partly</p>
            <p> 
                <bold>Comment:</bold>&#x00a0;The primary data consists of&#x00a0;
                <italic>Dragon Ball</italic>&#x00a0;manga material, but the article does not provide sufficient specific panel references or visual citations to support each argument. Some references to visuals or narratives are too general, lacking image support or exact chapter locations, making it difficult for readers to verify the evidence themselves.</p>
            <p> </p>
            <p> 6. Are the conclusions drawn adequately supported by the results?</p>
            <p> Answer

            <body>
                <p>I thank the reviewer for the careful and constructive reading of the manuscript. Below I respond to each of the four points raised.</p>
                <p> </p>
                <p> 
                    <bold>1. Lack of empirical data or reception studies</bold>
                </p>
                <p> The reviewer suggests adding reception studies or fan interviews to support arguments about audience perception and cultural implications. I appreciate this suggestion; however, the present study is intentionally designed as a medium-specific formal analysis of the manga text rather than a reception study. The paper examines the visual and graphical properties of 
                    <italic>Dragon Ball</italic> as a media object, drawing on animation theory and manga studies rather than audience ethnography. Incorporating reception data would require a substantially different methodological framework and is beyond the scope of this study. I have clarified the paper's scope in the Methods section to make this boundary more explicit.</p>
                <p> </p>
                <p> 
                    <bold>2. Lack of comparative analysis with other anime and manga texts</bold>
                </p>
                <p> The reviewer suggests broader comparison with works such as 
                    <italic>Akira</italic>, 
                    <italic>Neon Genesis Evangelion</italic>, and 
                    <italic>Parasyte</italic>. I note that 
                    <italic>Akira</italic> already plays a significant comparative role in the paper: Tetsuo's transformation in 
                    <italic>Akira</italic> is discussed at length in Section 2 as a counterpoint to the abjection dynamics in 
                    <italic>Dragon Ball</italic>, and the Neo-Tokyo explosion is referenced in Section 3.4 in the context of light and annihilation in Japanese anime. The paper thus does situate 
                    <italic>Dragon Ball</italic> within a broader landscape of Japanese visual culture. A systematic comparison with additional titles would, however, shift the paper's focus away from its core argument about the medium-specific properties of 
                    <italic>Dragon Ball</italic> as a manga text. I have added a brief note in the conclusion to clarify how the analytical framework developed here might be extended to other works.</p>
                <p> </p>
                <p> 
                    <bold>3. Imbalance between visual and narrative analysis</bold>
                </p>
                <p> The reviewer suggests more close readings of specific manga panels. I have added a further chapter reference in Section 3.3 to strengthen the grounding of the argument in the primary source material. I would also direct the reviewer's attention to Figures 1&#x2013;7, each of which is accompanied by detailed analytical discussion in the main text, and to the extensive chapter-specific citations throughout Sections 3.1&#x2013;3.4. The paper's analytical approach is to treat selected panels as evidence of broader medium-ontological patterns rather than to perform exhaustive panel-by-panel commentary; I believe the existing visual apparatus adequately supports this approach.</p>
                <p> </p>
                <p> 
                    <bold>4. Overemphasis on sexuality while neglecting masculinity</bold>
                </p>
                <p> I respectfully suggest that this comment reflects a misreading of the paper's argument. The paper does not simply emphasize sexuality; rather, its central argument is precisely that 
                    <italic>Dragon Ball</italic> systematically 
                    <italic>suppresses</italic> sexuality and romance in favor of an asexual, graphical mode of reproduction. The surface narrative of muscular masculine combat is acknowledged&#x2014;and indeed foregrounded in the Introduction&#x2014;as the mechanism through which this suppression is effected. In other words, the paper treats masculinity not as an absent topic but as the surface ideology that renders the underlying logic of dual reproduction invisible. Adding a separate analysis of hyper-masculinity along the lines suggested by the reviewer would duplicate rather than complement the paper's existing argument.</p>

            <p>While this paper holds an interesting premise, and approach - combining as it does the vastly popular manga Dragonball with a theory of 'line' that builds on previous work by the likes of Napier (as well as chiming neatly with the themes raised in the British Museum exhibition on manga, for example), the end result feels muddled, and overly intellectualized. While the theory may be solid, the delivery is scattershot - continually claiming to avoid narrative and focusing on the line itself, but ultimately spending more time on explaining character elements of the manga, than a convincing unpacking of the drawings themselves.</p>
            <p> </p>
            <p> There is definite academic merit here with a solid theoretical basis, but in its current state, it is not an enjoyable read - the textual analysis could do with substantial editing to clarify the points it is making, and all in all, aim toward a more direct presentation of its findings. As it is, it just feels like a self-reflective exercise in academic intellectualism. There needs to be much more done to make the analysis convincing - why should we care about all this? There is some hint of this at the end of part 3.4 with the discussion of Eisenstein, but it doesn't go deep enough in specific relation to manga/anime. More recent work by the likes of Dennison, Lamarre etc may help find links between this study and convincing arguments of anime's relevancy as a global media property. The conclusion claims the study forms part of a 'trend' in anime/manga studies, but ultimately relies too heavily on Napier only - the citation base is solid, but could be broadened.</p>

            <body>
                <p>I am grateful to the reviewer for such an engaged and perceptive reading of the manuscript. The reviewer's comments have been genuinely helpful in clarifying the paper's argument and improving its presentation. I respond to each point below.</p>
                <p> </p>
                <p> 
                    <bold>On the overall presentation and argument</bold>
                </p>
                <p> The reviewer's observation that the paper feels "muddled" and that it claims to focus on the line while spending more time on character elements is a valuable one, and I understand why the paper can read this way. I have revised the conclusion to make the theoretical logic more explicit: the paper's core claim is that in the static medium of manga, plasmaticity 
                    <italic>cannot</italic> be expressed as pure line movement but must pass through the vessel of the character (
                    <italic>kyara</italic>)&#x2014;and it is this necessary mediation that generates the "dual reproduction" central to the argument. I hope the revised conclusion makes clearer why the paper moves between line and character, and why this movement is the argument rather than a distraction from it.</p>
                <p> </p>
                <p> 
                    <bold>On "why should we care"</bold>
                </p>
                <p> The reviewer is right to press on this point, and I appreciate the sharpness of the challenge. I have added a passage to the conclusion that more directly articulates the broader stakes of the analysis: the paper's framework for reading how medium-specific properties of ink and line encode cultural and historical meaning offers a transferable methodology for manga and anime studies more broadly, and connects the formal analysis to Japan's postwar visual imagination in ways that I hope will resonate with readers beyond the immediate field.</p>
                <p> </p>
                <p> 
                    <bold>On Lamarre and Dennison</bold>
                </p>
                <p> The reviewer's suggestion to engage with Lamarre and Dennison is well taken and has pushed me to think more carefully about how to position this study within current debates. I have added a footnote in Section 2 that engages with Lamarre's concept of animetism (
                    <italic>The Anime Machine</italic>, 2009). As the note explains, Lamarre's framework focuses on the moving image and cel animation technology, whereas the present study addresses the static medium of manga&#x2014;but the footnote acknowledges the productive tension between the two approaches and situates the present study more clearly in relation to this influential body of work. Regarding Dennison's 
                    <italic>Anime: A Critical Introduction</italic> (2015), her focus on transnational genre history and industrial circulation is somewhat outside the formal and medium-specific scope of the present paper; I have addressed this point in the response rather than in the text itself, but I am grateful to the reviewer for prompting me to consider how the paper's argument might speak to those broader debates.</p>
                <p> </p>
                <p> 
                    <bold>On over-reliance on Napier</bold>
                </p>
                <p> The reviewer's point about Napier is well taken. Napier is necessarily central to this paper because her account of metamorphosis and abjection in Japanese animation provides the direct theoretical foil for the argument about 
                    <italic>Dragon Ball</italic>; without that interlocutor, the paper's contribution would be harder to define. That said, I take the reviewer's point that the conclusion's claim to situate the paper within a broader "trend" in anime/manga studies should be better substantiated. The addition of the Lamarre footnote, together with the existing engagement with Steinberg, It&#x014d;, &#x014c;tsuka, Bukatman, and Lippit, I hope, goes some way toward demonstrating that the paper is in dialogue with a wider field. I have also revised the relevant passage in the conclusion to frame the paper's position more carefully.</p>
                <p> </p>
                <p> 
                    <bold>On the citation base</bold>
                </p>
                <p> I am grateful for the reviewer's encouragement to broaden the citation base. The Lamarre footnote represents the most substantive addition in this regard. I believe the existing bibliography&#x2014;spanning English-language and Japanese-language scholarship across animation studies, manga studies, film theory, and philosophy&#x2014;reflects the interdisciplinary scope of the argument, and I hope the revised version demonstrates this more effectively.</p>
