Cocon dépeint la lutte pour la survie d’un groupe directement inspiré de l’escadron Himeyuri composé de jeunes filles enrôlées comme infirmières à Okinawa pendant la Seconde Guerre mondiale. Ces jeunes filles voient leur quotidien d’écolières, déjà chamboulé par la guerre, complètement anéanti lorsque leur travail en tant qu'infirmières commence. L’histoire est centrée sur le personnage de San, entre l’horreur de son quotidien et l’apaisement que lui procurent ses souvenirs des jours de paix relative. Cocon fait partie de ses œuvres qui ne cherchent pas à décrire la Seconde Guerre Mondiale mais le ressenti de ceux qui l’ont vécu. La douceur du trait et des aquarelles de Machiko Kyô ne font que révéler davantage l’horreur de la guerre avec une terrible authenticité.

A stunning, enthralling, and tragic tale of war-torn Japan. I’m so appreciative that I had the chance to read this account and step into the lives of these girls, whose voices might have otherwise been forgotten. The way their struggles are portrayed is both raw and haunting, a reminder of the human cost of war that history books often gloss over.
It’s not an easy read emotionally—it’s incredibly depressing and unflinchingly tragic—but that’s what makes it so powerful. The resilience, the pain, and the quiet moments of humanity shine through even in the darkest chapters. This book doesn’t just tell a story; it leaves an imprint.
What the actual fuck? Quoting from the book, "We have so much more freedom in this camp . . . Never imagined we'd living like this month ago. But even so, we're still prisoners." The author is leaving the story off on a 'happy note' with them in a prison camp? I had to go back and read it several times to make sure I wasn't mistaken.
Besides that, although the illustrations are amazing, there is so little dialoue and/or text that half the time the reader doesn't know what's happening. I had been going back and forth between a three and four star until I got to the end of the book. That's just crazy.
I received this book in a goodreads giveaway. My review is voluntarily given, and my opinions are my own.
“La crisálida de los suelos me reguardó de la muerte que ahogaba mi realidad.”
El manga nos contará la historia de unas chicas que están en el instituto y tienen que ir a la guerra a prestar ayuda médica.
Amé que el dibujo sea tan simple y que al mismo tiempo te transmita varias cosas. Me encantaron las metáforas y el final fue demasiado, no me lo esperaba.
La simplicidad de los dibujos le da cierta ternura, pero al mismo tiempo varías escenas llegan a ser fuertes y crudas.
En cuanto a la puntuación, la historia va muy rápido y me hubiera gustado que profundice más cosas. Igualmente en la última parte la autora hace unos comentarios que complementan el manga y en que está basada la historia.
A beautiful, heartbreaking, holy crap manga about a group of girls being drafted as nurses during the WWII in Japan. We see the events through the eyes of San and Mayu (though San is the real MC). How the girls are at first quite eager to do something for their country but quickly wishing to go home, to be safe, to go to their families. We see friends die in gruesome ways, we see the girls nurse people and have to help with sawing off legs and all that, we see bombs go off, we read that people are being told to commit suicide to avoid capture by the Americans who are coming (yes, really, and apparently they are even killing their own to make sure of that), and we see the girls running away when things go totally terrible. I was actually crying during many of the scenes as the girls are dying one by one. I was so hoping that San would survive, and Mayu as well. I didn't want everyone to die. It was pretty horrific at times and at times my stomach was clearly not amused with what was going on. Also another warning, attempted (or actual) rape. Oh, btw, I had a suspicion about Mayu. The ending was wow, that is all I will tell. Despite the gruesomeness, the fact this will break your heart, I would recommend this book.
I received an advance reader copy of this book to read in exchange for an honest review via netgalley and the publishers.
Cocoon is a manga graphic novel set in Japan during World War 2 and follows a group of young Japanese girls being drafted as nurses during the war. This was such a harrowing read but an important one as it draws a light on girls and women during the war who's story's aren't shared enough. The girls are keen to join the war effort and treat soldiers to do their bit but they never dreamed what horrors they would be facing. I would advise to check the trigger warnings on this before reading as it does contain topics that may be triggering for some. The illustrations are in black and white (as an ARC) and although done in manga style they are as harrowing as the story.
Difficile dare una valutazione in sè a questo manga. E' molto forte e crudo, con argomenti belli pesantucci ma che allo stesso tempo non sono da lasciare in disparte.
Mi sono trovata a leggerlo molto velocemente, complice il fatto della non troppa presenza di testo. Le immagini parlano da sole e sono più che sufficienti per narrare la storia da sole. Il tratto è molto particolare e devo dire che ci ho messo un pochino ad adattarmici. Non è tra i più dettagliati, nè tra i più fini. E' un tratto quasi abbozzato, stilizzato, ma che riesce comunque nel suo intento.
Una lettura che consiglio a tutti per gli argomenti trattati e come sono stati trattati. Una storia forte che vale la pena di leggere fino all'ultimo.
Me habría gustado que este tomo fuese más extenso para poder profundizar más en cada capítulo, personaje y situación, pero aun así es increíblemente duro y triste.
Me ha impactado bastante más de lo que me esperaba y por suerte ha superado mis expectativas, que tampoco eran muy altas. És un manga con la crudeza y el punto de vista de obras como "La tumba de las luciérnagas" o "En este rincón del mundo" y hasta ahora nunca había leído nada que me desgarrara tanto por dentro como lo hacen este par de películas.
El dibujo es simplista y a veces un poco confuso pero va acompañado de una muy correcta narrativa. Machiko Kyo a veces nos regala alguna doble página memorable, como la del capítulo de los campos en llamas.
En resumen, es una lectura dura pero ligera que plantea diferentes ideas de la autora sobre las consecuencias de la guerra a través de un recorrido hacia el infierno.
Muy bueno. La guerra desde el punto de vista de una niña que pierde a sus amigas es devastadora. Además de todos los temas que también toca, como el abuso sexual por parte de los soldados y la presión de serle útil a la patria. Tiene momentos devastadores en un estilo tan sencillo y bonito.
Very touching story and beautiful artwork. I did find the artwork sometimes interfered with clearly portraying what was happening in the story. The style is very loose and sketchy so at times it was hard to make out what you’re looking at.
A disclaimer at the beginning to indicate you’re supposed to read it like manga would also help the reader. Besides that, the story was very touching and harrowing at times. Definitely worth the read.
Thank you to NetGalley for providing me with an ARC in return for an honest review.
I requested this one from NetGalley on a whim. I liked the cover. I didn’t read the summary. I was not prepared for the psychological trauma that book brought on. In this story, there is a war and war has horrific costs. In this graphic novel, the horrific costs are laid bare. School is on hold because of the war and girls are recruits to be nurses to help aide the injured.
7.5/10 The Himeyuri were Japanese high school girls used as nurses during the battle of Okinawa, one of the last and most tragic episodes of WWII. Most of them did not make it to the end. Those not killed by diseases or the American bombings immolated themselves (with grenades), not to fall into the enemy hand, victims first and foremost of a foolish nationalism turned into madness. This book is fictional, but provides a most horrifically realistic depiction of the Himeyuri misfortunes, as maybe only a fictional book can. Machiko Kyo is renewed for her art style, capable of combining the aggressiveness of simplified lines to a very elegant sense of shapes. Her art feels sketchy, but soft. Hence, it fits well the underlying theme here, i.e., the tension between the emotional softness of teen age and the macabre of a war that turns young girls into pieces of flash and fluids scattered along an indifferent sunny beach. The pace is set by the format, as the story was serialised in fifteen monthly instalments, of twelve pages each. So, every twelve pages a new horror unfolds, as the girls are mowed one after the other. The lyricism of the author is strong but does not completely take over the tone of the book, which remains a no frills depiction of human butchery, how war should be depicted. Speaking of which, as I was finishing reading this news came out that they are making an anime adaptation, I assume in a style inevitably more realistic than the sketchy lines of Kyo. How are they gonna pull it? Visually, this is a terrifying story. One last thing. I know it would have been unrealistic to produce (at the pace of one chapter per month), but I would have loved to see this story fully coloured, because Machiko Kyo is a great watercolorist.
"If I was a silk-worm, I wouldn't come out in a world like this. I would stay safely inside my cocoon and in my imaginary cocoon, I would slowly die away but, truthfully, none of us wanted to die."
"My cocoon broke open and I emerged transformed. I may have wings, but I'm unable to fly which is why... I decided to live instead."

“Si fuera un gusano de seda, no querría volver a vivir en este mundo. Me quedaría en mi crisálida, donde nadie pudiera hacerme daño. Iría muriendo poco a poco dentro de mi capullo de sueños. Aunque... creo que en realidad... nadie está preparado para morir.”
Estoy destrozada. Completamente. En pedacitos. No me sentía así desde que ví La tumba de las luciérnagas, y esto es como esa peli pero duplicado. Hay escenas que me dieron náuseas de lo crudas que eran, aunque entiendo que ese era el propósito, mostrar los horrores de la guerra lo más crudo y directo posible. Creo que igual tiene un punto importante al mostrar como las propagandas de los gobiernos hacen que los jóvenes se entusiasmen con "entregar un servicio a su país" en la guerra, cuando al final los bandos pasan por ser una ilusión y los soldados de su propio país pueden ser monstruosos. No hay honor en la guerra, solo sufrimiento, horror y pérdida, y eso se deja claro.
Hay algunas cositas que sentí que faltó profundizar, especialmente la historia de Mayu, aunque la autora explica todo en la nota que deja al final.
En fin, es un manga que, en mi opinión, se puede leer una sola vez. Nunca lo volvería a leer, no lo soportaría🥹
I don’t really know what I want from fictional stories that cover the Battle of Okinawa anymore. I’ve read or watched a lot of war-related media where the protag is bright-eyed and committed to their side of the war, wanting to do their all. It’s not a tired story, it’s necessary, it’s a song that must be sung over and over and over cause same reality keeps happening and happening and happening.
But, I wish I knew more about the characters outside of their war-time lives, the before and after—the manga covers that all the girls were attending a school similar to the Himeyuri students, but their lives are narrowed to prominent shoujo tropes. I just get their pain, which, should be known, but not just their pain. Unfortunately, when narratives focus on just the war, readers just might not get how much was truly lost by the war, may struggle to understand the land, the people, or culture when it’s not tied down to violence and power. I’m always shocked when I see pre-wartime photos of Okinawa, when you see trains running or whole neighborhoods divided by limestone/coral walls.
The only war-time media that meets what I yearn for is In This Corner of the World / この世界片隅に.
Un manga desgarrador que retrata una época horrible. Me ha gustado sobre todo como todo se va degradando cada vez más y a más velocidad y llega un punto en el que es casi doloroso seguir leyendo. Muy interesante.
Cocoon és la història d'unes nenes que han de donar suport al cos d'infermeria durant la segona guerra mundial. La crueltat de la guerra es palpa a cada pàgina. 😔
Muy representativo. Es una historia clara, bien contada. Te lo cuenta "rápido", sin entrar en detalles en ocasiones, pero creo que a veces no es necesario porque ya te lo imaginas.
When the Cocoon Breaks, the Wings Do Not Save Her Machiko Kyo’s “cocoon” turns girlhood fantasy, wartime nursing, and the Himeyuri shadow into a manga of failed shelter and stubborn survival. By Demetris Papadimitropoulos | July 9th, 2026
Drawn first as a fantasy of snow by a girl who has never seen it, the cocoon in Machiko Kyo’s “cocoon” begins as an image almost too fragile to trust. Breath turns to silk. Voices weave white thread. A child imagines protection as something the mouth might make. The image is perilously pretty until the manga starts asking what such a fantasy can hold: a voice, a friendship, a body under orders, a body under fire.
Every household object in “cocoon” comes back with war inside it. Soap begins as a mother’s rationed kindness and reappears beside burning flesh and rubble. Milk, that nursery-white promise, becomes poison. Cake becomes dirt and birthday hallucination. Flowers become belated rites. Wings arrive, then decline their assignment. Machiko Kyo’s achievement is not that she contrasts innocence with horror. Many war stories do that, and some do little else, ringing the same solemn bell until the reader can hear the rope. Her sharper insight is that innocence is active: it invents spells, routines, songs, parties, and cocoons. It works until it breaks.
Mobilized from a girls’ school on Japan’s southern islands, San, Mayu, and their classmates are sent into the war effort as assistant nurses. The book is a fictionalized work rooted in the Himeyuri student nurses of Okinawa, but Kyo is not offering a documentary account or a substitute for testimony. The pages move by fracture and return: soap, milk, cake, pen nib, repeated phrases, hands that carry, bandage, and refuse to let go. History enters first as smell, then touch, then sound, then the image that will not leave.
Early on, San admires Mayu, a transfer student from Tokyo who has become the “prince” of the school, tall, beautiful, and slightly out of reach. San’s attachment is girlish, comic, adoring, and eventually life-keeping. Mayu is friend, spell-caster, protector, beloved mystery, and finally the person San will name as her cocoon. Their bond keeps the grief attached to a body, a voice, a hand. It keeps the book from becoming a thesis with casualties arranged around it.
The first chapters are full of air: island warmth, school chatter, postcards, flowers, soap, teasing, the solemn absurdity of adolescent alliances. This is not a sunny prelude before the “real” story begins. Kyo needs the vocabulary of girls who still expect desks to matter because the war will soon get into it. “Cake,” “soap,” “school,” “country,” “home,” “useful” – all will be repurposed by the battlefield. The catastrophe does not merely take their lives. It tampers with their words.
Rather than making San precociously wise, Jan Mitsuko Cash’s translation preserves a spare, panel-sized verbal texture. Sentences are short, often fragmentary, built for quick exchanges and sudden stops. The diction moves between schoolgirl chatter, patriotic slogans, medical horror, sensory memory, and cries of pain. The prose does not decorate the wound. Here the words stay close to the girls: practical, repetitive, frightened, sometimes funny because they have not yet learned not to be.
Inside the gama, the Okinawan cave hospital, the pages close in. The girls enter a space that should protect them and find instead a ward, a morgue, a military asset, a mouth that will not keep them. They nurse wounded soldiers in darkness, carry water, witness amputations, and handle blood, maggots, fever, and corpses. San’s fear of men becomes the spell of “white shadows,” a way to make male bodies less threatening by making them less real. It is a child’s spell, which is to say both fragile and serious. It lets her keep moving until one man becomes too real.
Panels that once had air begin to compress. “cocoon” moves from sunlit openness into black fields, blank exposure, tight interiors, and fractured motion. The linework is thread-fine, almost airy, which makes the bodies inside it seem unbearably small. Kyo’s softness is not a cushion. It is where the injury shows. The page itself behaves like a shelter – then shows, panel by panel, where the walls give way.
Art, in this book, is never merely an escape hatch. Hina, malnourished and increasingly removed from ordinary nursing work, keeps drawing. The repeated scratch of her pen nib becomes one of the book’s most quietly devastating sounds. SKRTCH, SKRTCH, SKRTCH: the pen keeps going after sight becomes unbearable. When San thinks Hina is lucky because she no longer has to witness reality, the thought is monstrous, merciful, childish, and plausible all at once. The pen keeps a small room open. It cannot make the room clean.
Propaganda moves through the girls less as lesson than as drilled reflex. They want to help their country. They want to be useful. They want fathers, brothers, teachers, and imperial abstractions to be proud. That desire to be good is one of the book’s crueler materials. “cocoon” is exact about obedience before the army ever gives its orders. The girls do not become expendable by accident. Their discipline, purity, service, and school pride have already prepared a channel through which the military state can pour them into danger.
At the structural center, the deactivation order clicks shut. The nursing unit is disbanded, not because the girls are being rescued, but because the army needs the caves. They are told to leave before daybreak, rely on their own judgment, and abandon the wounded if necessary. It is a reversal of everything they have been made to do. They were recruited to tend bodies; now they must save themselves by leaving bodies behind. This is not rescue, only eviction in the grammar of command.
During that final night in the gama, the girls sing. Their voices seem to make the ceiling glow white, as though they were protected by the snowy cocoon San imagined at the beginning. Kyo refuses to let the image become simply false. The song does protect something: a shared rhythm, a last schoolroom togetherness, a little dignity before dispersal. It does not protect them from shells, hunger, assault, flame, or tide. It protects about as much as a song can, which is less than a life and more than nothing.
In the flight chapters, reality begins to flicker: fire, schoolroom, hunger, beach, dream. “Sweet Milk” turns fairy-tale appetite into poisoned mercy-killing. “Sea of Flames” gives Etsuko’s pain a terrible clarity as San answers it with fantasies of tea, sweets, school, and harvest festival. “Sweep the Sand” slides into dissociation, translating battlefield terror into school cleaning, dates, and the hope of going home soon. The mind is not lying exactly. It is sweeping sand over what cannot yet be looked at.
Mayu’s role deepens as the book approaches sexual terror and the collapse of the white-shadow spell. A Japanese soldier threatens or assaults San; the danger is not only the enemy the girls have been taught to fear, but one of their own. Later, the Camellia Group chooses suicide under the pressure of chastity, honor, imperial devotion, and fear of violation. Purity here is not a virtue floating above violence. It is one more enclosure, and the girls are being asked to die inside it.
In one of the book’s sharpest revisions of its title image, Mayu rejects the suicide logic by saying that silkworms do not use hand grenades. They break through their cocoons on their own. The line nearly tips into motto, but it survives because it arrives amid panic rather than lecture. The cocoon changes meaning. It is no longer only hiding, dreaming, or waiting. It becomes the painful work of emergence, which is not the same as escape.
The book’s most treacherous motif may be soap. That seems almost perverse in a story full of caves, fire, corpses, and wings, but soap is where Kyo’s sensory intelligence is most exact. San’s mother gives her the last bar from their rations, knowing her daughter wants not to use it but to smell it. The scent clings to home, hands, cleanliness, girlhood. Then the same smell is laid beside burning flesh and molten glass. By the time rubble smells of soap, the object has stopped behaving like a symbol. It has become a trapdoor in the body.
Repetition gives the manga its spellwork and its occasional strain. The cocoon, silkworm, white snow, wings, and emergence language are named often, and readers allergic to overt patterning may feel the frame under the cloth. The author note also explains the motif system more directly than the pages require. There is a cost, too, to the dream-blurred approach: while the Himeyuri origin gives the work gravity, the symbolic atmosphere softens some Okinawan specificity. “cocoon” should not be asked to do the work of testimony.
One cost of this method is also what makes the book strange. Kyo is making a dream after history has entered the imagination. Her form depends on dislocation: school, cave, beach, hospital, birthday party, and battlefield keep collapsing into one another. If “Barefoot Gen” by Keiji Nakazawa burns with direct witness, and “In This Corner of the World” by Fumiyo Kouno gathers wartime pressure through domestic continuity, “cocoon” makes catastrophe feel like a nightmare built from a child’s remaining words.
Placed beside San’s need for shelter, Mayu becomes the book’s most delicate question. The author note says her story draws on a newspaper account of a boy raised as a girl to avoid conscription. That detail helps explain why Mayu stands at the crossroads of protection, gender, usefulness, purity, and violence. In the manga itself, though, Mayu remains more than a key to interpretation. She casts spells, keeps San moving, protects her, kills for her, loves her, breaks. When she kills to protect San, the cocoon is no longer a dream image. It has blood on it.
One reason the ending works is that it refuses the butterfly logic its own imagery appears to invite. A lesser book would let metamorphosis become consolation with wings attached, a tidy bargain from the symbolism department. San survives into a prisoner camp and discovers, bitterly, that the enemies she was taught to fear may be kinder than her own side. She reunites with family, but the world is rubble. Her school friends are gone. Mayu, “my cocoon,” has broken. San has emerged, but even with wings, she cannot fly.
Under the plot runs the book’s cruelest distinction: being protected is not the same as possessing an image of protection. San’s fantasies are not foolish. Mayu’s spells are not empty. Hina’s drawings are not distractions. The side story “Birthday Cake” makes this plain by giving Hina a celebration made from hunger, dirt, and dream. Birthday cake made of dirt is still, for one instant, a birthday cake. Kyo grants imagination its dignity and denies it a magical pardon.
Little here decorates suffering for atmosphere’s sake. Flowers, waves, birds, hands, cakes, and black panels return stained by what has happened around them. Hands may be the quietest ethical motif: holding hands, carrying, bandaging, refusing to let go, failing to keep hold. Against imperial language and military orders, a hand is the book’s smallest practical truth. It cannot stop history. It can still decide, briefly, not to release another hand.
One can admire “cocoon” deeply without calling it flawless: 88/100, which translates under my rubric to 4/5 stars. The score marks a work just short of the top tier, not because its feeling is thin, but because the gears of the metaphor are sometimes visible and its dream logic leaves some history blurred at the edges. Still, its finest pages understand something more difficult than despair. They understand the shelter that holds for one song, one hand, one breath – and then tears.
So when San says she has decided to live, the sentence does not arrive as triumph. It is smaller, plainer, and more exact. The cocoon has failed as rescue but survived as trace. It has preserved enough of her to continue without pretending continuation is flight. Kyo leaves us not with a butterfly, not quite, but with a girl standing in the world after the thread has torn, wings present, useless, and still somehow part of the body.
I went into this manga thinking itd be a fun, pleasant, feel good story. So to be hit with quite the opposite did make me a bit traumatized but.. still good to learn about different stories
