Manga: Cage of Eden

Cage of Eden (original title エデンの檻, Eden no Ori) is a Manga by Yoshinobu Yamada which can be summarized as "LOST, but as a manga."

A class of Japanese high schoolers are on their way back from a trip to Guam when the plane hits a freak turbulence and crash-lands on an unknown island. The place turns out to have an ecosystem stuck some 50 million years in the past, with all manner of dangerous megafauna.

Class clown Akira, who had initially found himself isolated, manages to gather a small group of survivors—a flight attendant, his childhood friend, a reclusive geek, and a friendly delinquent. Together they try to survive in the hostile environment.

However, the most dangerous creatures on the island may turn out to be of the bipedal kind...

There is now a Character Sheet that could use some love.

The manga has now ended with 185 chapters, something that was announced on December 21st 2012.


Contains examples of:

  • The Ace: Yarai. He's not completely perfect, though, thanks to poor leadership skills and a complete inability to take anyone else's orders...both of which traits, coincidentally, also prevent him from hogging too much of the limelight.
  • A Child Shall Lead Them: A group of adult survivors is under the leadership of a 10-year-old girl. Who's, uh, not actually a girl...
  • Action Girl: Miyauchi, full stop. The other girls aren't quite at her level, but they hold themselves pretty well for people without formal training.
  • Adults Are Useless: With the single exception of Oomori, who has useful first aid skills.
    • Also, the vast majority of the male adults are creepy perverts. The school boys are perverts too but the adults are far more likely to take it too far. The age difference between luster and lusted-after often doesn't help in the creepiness stakes.
    • Kokonoe Ugen, the science teacher, is an exception to both the "creepy pervert" and "useless" rules. Although he hasn't had too much time to show off, he has used his skills to make a few good explosives.
  • Altum Videtur: "Isurugi Miina, Requiescat In Pace" (Rest In Peace). Anyone who has played the Assassin's Creed series will see this straightaway.
  • Alternate Timeline: While it had been heavily implied that they were actually in the future, Chapter 166 provides the biggest proof of this so far in the series, when Segawa notices the real Miina's drawings of one of the creatures, and realizes she's holding an old and weathered version of it that she had found somewhere else in the island. In Chapter 169, Rei realizes that one of the cars in the final tower is a Yotsubishi, but can't recognize the specific car. Chapter 182 confirms it.
  • Anachronism Stew: It's noted early on that the extinct animals encountered are from too far apart in the fossil record both chronologically and geographically (the very first chapter has fauna both from 57 million years ago and from 2 million years ago; by volume 5 there's been everything from recently-extinct birds to Triassic-era mammalian reptiles and amphibians except dinosaurs) to make sense on its own. This is something that gets discussed in-universe as well, when trying to figure out the nature of the island. Justified. As of recently it is discovered that all of the extinct animals were actually genetically engineered by humans of various nationalities.
  • And the Adventure Continues: The manga ends with them sailing off to whatever's left of Japan.
  • Animal-Eared Headband: Yarai makes Kurusu wear some, telling her they'd protect her from animal attacks, which she believed at first (he reveals the deception soon enough, though).
  • Anyone Can Die: Many, many characters, most notably Zaji and now Tooru have been abruptly killed off.
  • Apocalyptic Log: Eiken's video camera serves as exposition to what the rest of the survivors had been up to since the plane crashed. It spoke for itself.
  • Arc Villain: Nishikiori of the second to final arc.
  • Attempted Rape: Being a beautiful girl is unlucky in Cage of Eden where there's a chance a horny bastard wants to rape them. And when Kotomi's Sanity Slippage gets worse, she... doesn't exactly take Akira's refusal to have sex with her very well.
  • Back from the Dead: Subverted with Kouhei on the “cursed mountain”.
    • Though a recent chapter reveals he wasn't as dead as previously assumed.
  • Bad Ass: Yarai. He once had to fend off three chalicotheres. While carrying someone over his shoulder. With car keys. The only damage he took was from being smashed into a tree to stop them from attacking the rest of his group. It broke three of his ribs. His response was roughly "Pfft, only three ribs"? He made them run like pansies by ripping off one of their claws.
  • Bald of Evil: The artist's utterly bloody terrifying impression of the extinct giant ape, Gigantopithecus.
  • Barbie Doll Anatomy: The girls are frequently drawn naked, but lack nipples or pubic hair.
  • Batman Gambit: Akira pulls one off in order to find out who hit Miina and left her to die.
  • Bears Are Bad News: Especially when they're gigantic with long arms and legs.
  • Beauty Is Never Tarnished:
    • Kurusu-sensei doesn't suffer any permanent damage from the eye disease despite being the first to contract it.
    • Averted many times over the course of the manga, though; many of the girls take bruises and cuts during battles with the wildlife, and many more are killed in horrible fashions.
  • Big Damn Heroes: Yarai vs Cerberus
  • Big Eater: Akira.
  • Bittersweet Ending: At the end of the manga, there have been several casualties for the passengers (including Zaji and Tooru). Their parents and relatives died, believing their loved ones died on a plane crash. But the group is still alive and strong, ready to set sail from the island to return to the outside world.
  • Bland-Name Product: Yotsubishi Heavy Industries is a spoof of an actual Japanese heavy machinery company, Mitsubishi (it also does a lot of other things). Hence the logo with four diamonds ("mitsu" = three —> "yotsu" = four).
  • Broken Ace: Kouhei would be a classic example, a smart, athletic, good-looking, and all around wonderful guy who starts off by killing the pilot during a mass panic and slowly goes off the deep end from there.
  • Buxom Is Better: Several of the characters have large bosoms. Especially considering that most of them are in high school.
  • The Cassandra: Subverted with Mami. Her own group doesn't believe her real premonition and is revealed to be a fake to Akira's group. Certain "coincidences" are starting to change everyone's opinions about her.
  • Character Development: Lots of characters get this treatment. Especially Akira. Starts off as the class clown, but grows to be a highly effective leader.
  • Chaste Hero: Despite Kotomi undressing and flat out attempting to force him to have sex with her, Akira refuses, simultaneously putting Kotomi in her place, while also wondering about what Rion would think if she were to walk in on them in the meanwhile. He's arguably a full blown Chivalrous Pervert but he's trying to stay loyal to his crush and childhood friend Rion. It helps that they've made it pretty clear to one another that they like each other, from as early as the first 10 chapters no less.
  • Chekhov's Gunman: Miina (or her body double) wasn't even properly introduced, yet the double can be seen running, back toward the camera, during Eiken's video recording of the airplane riot.
  • Clingy Jealous Girl: Rion doesn't like the fact that other girls are attracted to Akira as well.
  • Clueless Chick Magnet: Akira, as highlighted in chapter 167.
    • Mariya too, surprisingly enough. When the girls had a little game where they said which boy they'd like to spend the night with, he got six votes out of sixteen.
      • Though there are hints that Mariya was a 'dummy vote' or 'non-answer', from the reactions of the girls. Considering he's one of the few guys to not perv and have no romantic moments whatsoever, this would make sense.
  • Crapsack World
  • Cruel and Unusual Death: Several characters meet this end. Such as Towa, who was gang raped to death by the people she was trying to help.
  • Darkest Hour: They have finally have a decent plan to stop Cerberus and another monster appears. Kouhei prevents said monster from ruining the plan by dragging it underground (though no one sees him properly and the people used as bait are burning their shirts to get Cerberus's attention back.
  • Death by Flashback: Tooru.
    • Akira's mother and Miina's grandfather.
  • Death World: The island.
  • Delinquents: Both friendly and unfriendly ones.
  • Determinator: Akira, and his team by extension.
  • Dirty Coward: Suzuki. Though he seems to be getting better, if Chapter 150 is any indication.
  • Dojikko: Oomori was one at the beginning of the series, but has since Took a Level in Badass.
  • Dropped a Ceiling on Him: Tooru.
  • Easily Forgiven:
    • Never mind that Kouhei kills a good number of other teens in his group and has others in the group adopt his same mentality and kill the rest, Akira still sees him as his friend. Then Akira's inner monologue reveals that he considers Kouhei's actions to be unforgivable; the malaise and conflict that would have inevitably resulted from the cognitive dissonance had Kouhei (who despite being aware by that point of how much he fucked up was still an insane, brain-damaged murderer) joined the group was thus conveniently resolved. Once the reader discovers that Kouhei is still alive, he doesn't feel he deserves to show himself to Akira.
    • The list for this goes on and on. While quite a few Jerkasses die Karmic Deaths, any that do survive are typically forgiven, regardless of how horrible they were.
    • Lampshaded at one point by Rion as she complains about letting some of Nishikiori's men walk around freely, even though they tried to rape the students. Mariya replies that if they punished them, they would hold a grudge against them, aggravating even more conflict. While they did despicable things, they had to work with each other in order to survive.
  • Eldritch Abomination: Most of the extinct animals on the island. But especially the failed hybrids.
  • Everything's Better with Dinosaurs: Averted. They're pretty much the only set of extinct species that don't show up.
  • Everything Is Trying to Kill You: On this island, even the flora is dangerous. Plants almost killed the group twice.
    • One of the biggest dangers to the group of humans is themselves. People who land on this island tend to become insane and lose all sense of humanity for no explained reason.
  • Eye Scream: The characters fall victim to a disease that causes their eyes to become bloodshot, and in the terminal stages to become so swollen with blood that they burst.
    • The giant bird rips out and eats the eye of its still living prey.
  • Fan Disservice: Kurusu, down to her underwear, for her makeshift surgery.
  • Fate Worse than Death: Several people meet grisly fates on the island. But the worst one was arguably Oomori's senpai getting gang raped to death by 17 men, the very people she was trying to help.
  • Friend to All Living Things: Well, there's not exactly very many friendly beasts on the island. But the one species so far that hasn't tried to kill the humans, the little flying squirrel things, really like Oomori, to the point that one has willingly become her pet.
    • Also, Akira and the alpha wolf of the resident wolf pack seem to have reached an understanding of sorts—the wolves don't hurt the humans, the humans don't hurt the wolves, and they all work together to stop the bears. Well, they would, naturally.
  • Gainax Ending
  • Genius Bruiser: Yarai himself.
  • Get a Hold of Yourself, Man!: Mami to Yarai, after Yarai has a Heroic BSOD. It snaps him out of it.
  • The Glomp: Whenever Rion wants to express her happiness for finding out that Akira is still alive, she does this by jumping onto his upper body.
  • Gone Horribly Wrong: Turns out the whole island used to be a large research facility dedicated to reviving extinct animals.
  • Half-Identical Twins: The Narumi twins, Kairi and Airi.
  • Hallucinations: What happened to Akira and most of his group due to acute mountain sickness.
  • Harmful to Minors: Miina (the fake one) witnessed her group's assault and murder of Towa.
  • Hot Teacher: Miss Kurusu. Kokonoe isn't all that hard on the eyes, either.
  • Huge Guy, Tiny Girl: Kouichi Yarai, the school delinquent, and Motoko Kurusu, the teacher, who has effectively become his tag-along. Played up when he carries her in chapter 19 and the Japanese cover for volume 8.
  • Humans Are Bastards: Reconstructed. Several of the passengers do horrifically terrible things when put under the stress of being stranded on an unknown island. But when Akira leads the survivors, they become a cooperative, functioning group that risks their lives in order to protect each other.
  • Improvised Weapon User: Yarai's specialty, with particular favourites being his set of car keys and collection of five-hundred-yen coins.
  • Infinite Laptop: Mariya's laptop never runs out of juice, even though he spends most of his waking hours using it. In chapter 54, it is finally subverted when the mystery of its power source is revealed to be a simple foot pedal peripheral that Mariya conveniently took to Guam instead of power plug adaptors. Where he kept the power adapter is another question.
  • Intimate Healing: Rion gets an unconscious Akira to ingest the remedy to the eye disease by chewing it and regurgitating it into his mouth.
  • Jerk Ass: Suzuki, to the point where fans were actually happy when he was attacked by the bird.
    • Several fans were disappointed in chapter 93 when he was attacked by ANOTHER species of bird, but was then spat out.
  • Karma Houdini: So, so many. A couple of the biggest examples may be Hades and Kouhei. Somewhat averted because they exile themselves from the rest of the group and have to fend for themselves. But they don't really suffer that much punishment for the large number of people they killed.
    • To a degree, Nishikiori. He did lose control of his slaves, got beaten pretty badly, and lost a leg. But at the end, it's shown that he's still allowed to live with the group freely. Despite killing several people and enslaving/terrorizing others.
  • Kiss of Life: After rescuing Rion from drowning, Akira has to practice mouth-to-mouth resuscitation on her.
    • Rion later returns the favor by giving him the antidote to a poisonous berry through mouth-to-mouth.
  • Laser-Guided Karma / Karmic Death: It’s a sound tactic when surviving in Cage of Eden to not do anything evil. Cases include:
    • Yoshimoto and Mukouda steal the raft in order to reach a distant island, leaving everyone to die. Turns out it was just a mirage, and they’re quickly eaten.
    • A group of men that raped and killed Oomori’s senpai get their just deserts when several groups of giant predators devour them all because they were attracted by the blood of the people they just killed a few minutes ago.
    • Kouhei. invoked After realizing he has crossed the Moral Event Horizon, he goes on a killing spree and convinces four of his group to adopt the same mentality as he did. Once he meets Akira, he regrets what he has done. As a flash flood threatens everyone’s safety, the group of followers disregard his advice and drown. Kouhei leads Akira and his group to safety, and subverting the trope, he chose to stay behind.
    • Kotomi. Manipulates men and attempted to choke Akira to death after he rejected her. She falls off the cliff behind Akira and dies.
    • Ryouchi. Manipulates women and attempted rape. Gets manhandled by giant condors.
    • Nakamura, Mami the Clairvoyant's manager, and the rest of their group. They make sure their leader's predictions come true by killing some of Akira's group. Then after their attempts to slow down Akira's group and leave them to die, all of them are eaten by crocodiles, exactly as Mami predicted.
  • The Leader: Akira's a mix of Type III and IV. He often preaches by example, and one character even explicitly tells him (in confidence) that he actually induces courage in others.
  • Left Hanging: The Manga abruptly ended after 182 chapters. While the mystery of the island was solved, HOW the survivors wound up there was never explained. Kouhei and Hades's fate was, likewise, left in the air (though it's implied that they were simply left behind on the island, perhaps symbolic of how they can't rejoin civilization).
  • Let's You and Him Fight: Yarai and Sengoku, which we have Nishikori to "thank" for.
  • Like Brother and Sister: Akira and Rion, though the UST between them is obvious to everyone else. They have displayed outright affections for each other very early in the story, with each initiating their own kiss scene (even if it was to save the other's life, its easy to tell that they wanted it). Its just that, whenever asked directly, they deny it. Both are starting to acknowledge their feelings for each other in later chapters.
  • Living on Borrowed Time: Kurusu-sensei, thanks to Mortal Wound Reveal — she's supposedly unaware of it.
  • The Load: Mostly averted in Akira's group, as no one wants to slow down Akira and are all willing to do whatever they can to contribute. However as Tooru pointed out, the lack of someone to go "I'm tired, let's stop walking," almost took the lives of everyone in Akira's group when they attempted to climb a mountain too fast.
  • Loads and Loads of Characters
  • Lolicon: More than a few on the island—all Played for Laughs. There's the perverted monk, who lusts after the schoolgirls (and became a monk in the first place to dodge an Enjo Kosai scandal), but won't even look at the college girls or adults. Then there are three of Nishikori's men, who are convinced to turn on their boss because Fake Miina flashed his panties at them. Miina claims that most of the world's perverts are lolicons, so "He who controls the lolicons controls the world."
  • Lost World: What the heroes have to survive in.
  • Love Letter Lunacy: Let's just say that a group of delinquents mistook a locker that they thought was Yarai's and go on from there.
  • Mad Scientist: Kokonoe Ugen, the science teacher. He was known for blowing up his classroom on a regular basis.
  • Male Gaze
  • Mega Corp.: Spiral.
  • Meganekko: Kusuru-sensei.
  • Morally Ambiguous Doctorate: Nishikiori, full stop. Except he doesn't have a doctorate, nor is he a doctor.
  • Murder Makes You Crazy: This is what breaks the ace, Kouhei. This combined with a head injury that damages his ability to feel responsible for his own actions... After killing the pilot during a panic, he feels incredibly guilty and paranoid. When one of the girls he's traveling with claims she saw him murder the pilot, he kills her to protect his secret, and then told that she had been manipulated into saying that and hadn't known all along. Realizing that he'd murdered her pointlessly, combined with the brain damage which made it impossible for him to 'feel people looking at him', makes him go off the deep end and kill more people, even when it serves no purpose. He even bullies and tricks the other students with him into doing the same thing so that they end up crazy like him (minus the head injury).
  • Never Found the Body: Zaji. Kouhei as well, although there's a reason for that.
  • No Romantic Resolution: The final chapter doesn't give any clear indications of romance.
    • This is applied to Akira and Rion. At the last chapter, it's cleverly drawn that it looks like they might be holding hands. Even then, it's very unclear and can't be considered a "resolution."
  • Obfuscating Stupidity: Oomori, who can apparently read Latin, something even Mariya can't but hasn't told anyone due to self-confidence issues.
  • Older than They Look: Several of the students. Especially Yarai.
  • Outdoor Bath Peeping: Akira gets a glimpse of Oomori bathing in a river. He later gets a clear view on Mami, as well.
  • Panty Shot: Rion and Oomori frequently expose their panties.
  • People Jars/Designer Babies: All the extinct animals in the island.
  • Pedophile Priest: Seigou, though he's technically more of an ephebophile (and a relatively harmless one at that).
  • Photographic Memory: Hatsuse Shizuka
  • Poor Communication Kills: Averted; as Yarai's group begins to succumb to illness, he has his lackeys force Akira's group out of the cave that the latter group had discovered and were both sharing. Akira, however, realizes that Yarai is trying to quarantine his own group to prevent the spreading of the sickness, and has his people move out of the cave obediently. Turns out the sickness isn't exactly contagious, though...
  • Ragtag Bunch of Misfits
  • Rape as Drama: Oomori's senpai's fate is a particularly nasty one.
  • Recycled IN SPACE!: LOST: The Manga, at least at first glance. This is in no way detrimental to the series however.
  • Rescue Romance: Isurugi Miina seems to have started falling for her body double, the boy typically referred to as Miina after being saved by him more than once. Akira and Yarai also tend to attract admirers this way.
  • The Resenter: Shuu Hikime.
  • The Reveal: They're about 50-60 years in the future, in a timeline where they died... And the fake Isurugi Miina's name is Heijirou
  • The Rival: Kouhei and Yarai both fit. Kouhei especially, when he teams up with Akira to become Back-to-Back Badasses.
  • Sacrificial Lion: Zaji.
  • Screw This, I'm Outta Here!: Two new characters who showed up to Akira's camp act this way towards their previous group, after being completely disgusted in the actions  of their new leader, who they call a tyrant.
  • Schoolgirl Lesbians: Oomori became a flight attendant so she could be with her former senpai, whom she had a crush on in school. She claims it was because she went to all girls schools and is now interested in males.
  • Science Is Bad: Subverted. Turns out all the extinct animals were revived via genetic experiments. It's at first implied that they broke out and killed the researchers there, but it's later revealed that things didn't go wrong until the researchers were poisoned and the animals were released (since nobody was guarding them anymore). It's implied that the killers did this because they felt like they had intruded on God's territory. So it's less of science being bad, and more like fanatics believing that it is.
    • Also worth mentioning is that even after the animals were released, they were on a relatively uninhabited island. It didn't really do anything bad until the plane crashed there.
  • Secretly Dying:
    • Inverted, only those close to Kurusu-sensei know that she's dying, but Kurusu-sensei does not. It is revealed later on that she might know that she's dying.
    • Tooru is crushed by a collapsing ceiling and feigns being alright to keep Rei happy, and secretly asks Sengoku to look after her before dying.
  • Serial Escalation: The new monster that appeared AFTER cerberus.
  • Sexy Stewardess: Oomori.
  • The Short Guy with Glasses: Mariya
  • Shoutout: Possibly unintentional, but recently, a girl on the kendo team, named Kirino, has been introduced.
  • Shown Their Work: Everywhere. In addition to the extremely well-researched extinct animals, the author displays extreme medical knowledge in the character's injuries. What's more, the villains take advantage of groupthink and other psychological tricks to control their followers. The characters even reference numerous real-life historical events when trying to explain things to the others.
  • Straw Nihilist: Several of the survivors treat their predicament as a chance to practice survival of the fittest. Hades beats them all.
  • Sugar and Ice Personality: Yarai, see Jerkass Façade.
  • Tap on the Head:
    • Happens to Akira on at least two occasions.
    • Averted elsewhere. More than one character has received brain damage from "taps."
  • Teacher/Student Romance: Appears to be one between Kurusu-sensei and Yarai.
  • These Hands Have Killed: Kouhei, after stabbing the pilot.
  • Time Skip: nearly every chapter towards the end
  • Took a Level in Badass: Everyone, and especially Oomori (who at first was scared of a very small furry animal, and later takes a stab wound from Kouhei and then tries to write it off like it's nothing.) She willingly swims out to save Mariya from drowning.
    • Mariya, after Zaji's death.
    • Pretty much the whole entirety of the large group of students the main characters meet and join. They do start off making a nice fort to live in but are clearly not good at the proper surviving part. Overtime, though, they all become tougher, learn to work better as a team and casualties drop severely, to the point that almost all of them make it to the end of the story alive.
  • The Unreveal: The manga never explains if they're actually clones, used technology to bring them into the future, or them ending in that future was just a mere coincidence.
    • Hades's identity.
  • Unwanted Harem: From Rion's perspective: every single female character admits to having romantic feelings for her Akira in chapter 167, much to her horror.
  • Used to Be a Sweet Kid: Yarai.
  • The Vamp: Kawana Kotomi
  • Victorious Childhood Friend: Rion....maybe.
  • Waif Prophet: The real "Miina"
  • WHAM Chapter:
    • Chapter 61: It's not an island
    • Chapter 82: Zaji dies, Morita Makoto (the guy with the camera) and the real Isurugi Miina are still alive, and their group is heading to a structure Morita saw in one of his photos...a seemingly manmade structure...
    • Chapter 127: The entire island was a research facility.
    • Chapter 136: The island is part of Japan, and closer to mainland Japan than they thought.
    • Chapter 143: Something was hibernating under the tower with traps and it's now awake and hungry. What is is? A giant mutant Cerberus.
    • Chapter 147: The fake Miina is swallowed alive by the Cerberus.
    • Chapter 149: There is more than one mutant.
    • Chapter 150: Someone's taking care of the second mutant. It's KOUHEI. If that wasn't bad enough, HADES is also back.
    • Chapter 161: Nishikiori is not really a Doctor.
    • Chapter 166: The island might not actually be close to Japan.
    • Chapter 182: They're in the future.
    • Chapter 184: It's at least 40 years into the future, and they might be clones.
  • What Happened to the Mouse?: The manga ends after a three-year timeskip and leaves several plot points unresolved.
  • What You Are in the Dark: It soon dawns on the group (and the readers) early on that the animals aren't the only beasts they should be scared of.
  • Wholesome Crossdresser: "Isurugi Miina".
  • Why Did It Have to Be Bugs?: Maya Miyauchi, normally a Badass Action Girl does not take well to giant dragonflies.
  • The Wiki Rule: Eden no Ori Wiki
  • Your Mind Makes It Real: The hallucination was so powerful for Akira that signs of being strangled showed up on his neck.
  • Zettai Ryouiki: Rion.
