The Hero, Ganta is a Mistaken for Murderer and imprisoned in Deadman Wonderland after his entire school class were massacred by the "Red Man". Implanted with the Red Man's Branches of Sin, Ganta earns the nickname Woodpecker, becoming a Deadman. Wishing to gain freedom, Ganta meets the cheery Shiro, a long lost childhood friend, and tries to survive in the prison against the other inmates, Deadmen and the Red Man.Tropes associated with Ganta:
The Atoner: The Reveal about Shiro and Ganta's mother has left Ganta blaming himself for Wretched Egg existing. He is now determined to make things right.
Also subverted. He struggles with his feelings of love and his hatred for the monster that she is, and in their fight he is alternating between a heartfelt plea and trying satisfy his rage by ripping her to shreds.
Awesome, but Impractical: His Ganta Gun turns his blood into bullets. The thing is, while all the other Deadmen's fighting styles let them recycle blood easily, Ganta's does not. Meaning he shoots out his own blood to fight, without getting it back. Though this has obvious consequences early in the series, see Difficult but Awesome for its true potential. Leaving that aside, though, the crystal in his chest that is the source of his powers is slowly killing him.
Took a Level in Badass: An incredible leap right before Chapter 56, where he is skilled with his branch of sin and powerful enough to destroy, absolutely obliterate, level, shred and sink the island Deadman Wonderland is on. The entire time, Shiro is doing the same thing to him, which he deflects.
Batman Gambit: He frequently tries to distract his foes while getting ready to attack them. When working with Senji against someone else, they both rely on each other taking certain openings when they're available.
Cast from Hit Points: Well, when you are using your blood as ammunition that you shoot at other people, your hit points are litteraly your ammo. Ganta learns this the hard way during is second fight with Crow.
Combat Pragmatist: Very good at using the environment to his advantage, and throws in headbutts and such. When fighting the Wretched Egg towards the end of the manga, he actually gets up close to exchange blows.
Covered with Scars: He accumulates quite a few scars over the course of the series. Not surprising given the hell he goes through. By the end, his own scaring looks pretty similar to that of Shiro and Hagire. Yes, this is symbolic.
Determinator: In the words of Shiro, "Ganta always gets back up."
Deadpan Snarker: Though "deadpan" is an exaggeration most of the time, in the anime especially he has some smartass moments.
Destructive Savior: The Woodpecker analogue. The recurring song is that the woodpecker's beak is full of poison and it goes around boring holes in trees, eventually destroying the forest and everything it loves in the process. Close to the ending of the manga validates him as such.
Difficult but Awesome: Ganta's ability is one of the most powerful single Branches of Sin. However, the shots can't be recycled, so he has to make them count. If he concentrates, he can use tiny droplets of blood, which are faster, less costly, and more destructive. He can do the opposite and charge the shots to be explosive. This, combined with the long reach means that his power is extremely versatile in addition to being powerful. Unfortunately, the high cost and the inability to aim his shots after firing means he typically has to attack from close range or aim really well. Thankfully, Ganta is very good at choosing his shots.
Comes to a head in the epic Chapter 56, where he counters Shiro's many incredible powers with precise powerful shots, though he can't get a bead on her.
Expy: Fourteen year old boy who starts off as a crybaby and takes multiple levels in badass afterward out of necessity? Check. Fourteen year old love interest who knew him from a long time ago that he doesn't remember and has a totally crazy, iftragic side to her? Check. Only sane man in a crazy, dangerous, game-like world that drew him in against his will and keeps trying to kill him? Check. Starts going semi-crazy mid-way through the series? Check. One-eyed, one-armedbadass elder best friend who starts off as an enemy but becomes a sort of surrogate elder sibling? Aforementioned love interest asks him to kill her towards the end of the series? Check. Gee, where have we seen this before?
The authors worked on the Eureka Seven manga before, which may explain why Ganta is also reminiscent of Renton Thurston.
Flipping the Bird: He flips off the audience of the Carnival Corpse when they demand that he kill his defeated opponent.
Good Old Fisticuffs: Will eschew his blood powers to physically attack his foes if he has an opportunity. Makes sense, since he needs to conserve as much blood as possible. He actually attacks the Wretched Egg up close and does pretty well for himself, forcing the Wretched Egg to retreat.
Hand Cannon: The upgraded form of his Branch of Sin is this. By the end of the series, it's a full-blown Wave Motion Gun that totally levels Deadman Wonderland while fighting the Wretched Egg.
He goes back to being one in the epilogue, though he visits Shiro in the prison hospital every single day, and brings her candy.
Parental Abandonment: After realizing how dangerous the situation with Shiro was getting, Ganta's mother sends him off on a van while she stays behind. There's also no mention whatsoever of his biological father.
Chapter 53 reveals that she did this so that she could finish the Mother Goose System. She killsherself shortly after, both to prevent Hagire from learning how to turn it off, and out of guilt for what she did to Shiro.
Chapter 54 also reveals that before giving birth to Ganta, that she was as heartless as Hagire ever was and had even planned on using her then unborn child as their needed test subject. After his birth, however, motherly instinct kicked in and she gave him to the care of a male doctor who was leaving the facility to save Ganta from the fate that she herself had given him prior.
Person of Mass Destruction: Holy God, chapter 56. He and Shiro destroy Deadman Wonderland, as in sinking it after razing the amusement park to the ground, merely by the crossfire of their attacks.
Unstoppable Rage: The death of his friends at the start of the series is an incredible source of anger for him. It's enough to make him hate Shiro with murderous, homicidal rage. Though he alternates between that and incredibly strong love.
Ultimately subverted. When push comes to shove in Chapter 56-b, he can't bring himself to finish Shiro off, and instead wants her to come live a normal life with him.
You Will Not Evade Me: At one point when he fights the Wretched Egg, he lands a vicious hook to her head. She nimbly flips away, but Ganta reflexively turns, reaches out and grabs her leg to yank her back.
A mysterious but cheery Albino girl, Shiro becomes Ganta's closest friend in the prison. A bit of an airhead with a child-like mind and love for eating bread and candy, Shiro is actually Ganta's Forgotten Childhood Friend. Actually the Wretched Egg responsible for killing Ganta's friends, the upbeat Shiro being one side of her personality. Her antics as the Wretched Egg in her and Ganta's youth traumatized Ganta into forgetting she ever existed.Tropes associated with Shiro:
Broken Bird: Dear lord, is she ever. Her resentment for Ganta living a privileged life and the dehumanizing experiments she was put through clinches it. She could seriously be a candidate for Goddess of this trope.
Brought Down to Normal: Without her powers, she spends most of the final chapter in a coma in prison, though she does eventually wake up.
Death Seeker: Very much so. She caused the Tokyo earthquake in an attempt to force an RROD on herself.
And even this too is a lie as revealed in 56-b. She wants to be a normal girl but since that's highly unlikely to happen, death is her Plan B.
Despair Event Horizon: Chapter 55 reveals that she crossed this after finding out from Ganta's mother's journal that she was a replacement subject for Ganta. And she was still a little girl when this happened...
Does Not Like Shoes: As a child, she was always barefoot. In the present, she wears a jumpsuit that covers part of her soles, but her bare toes and heels stick out.
Also of note is the fact that the lieutenant general of Unit 731, a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that operated during WWII, was named Ishii Shiro. This was a hint at her origins as a human experiment.
Perhaps more of a coincidence than intentional, but there is also a type of Indian sweet called Shiro, which fits in well with her love of candy.
Obfuscating Stupidity: Chapter 55 proves she blows even Minatsuki out of the water for being a good actress. Everything from her Cloudcuckoolander antics to her Split Personality were not only faked, but a ploy to make Ganta strong enough to kill her, both physically and emotionally. The only person who didn't seem to be fooled was Hagire, and even that is debatable.
Pet the Dog: Kinda. While she doesn't kill the lamb that the crazy evil scientists put out for her to use her branch of sin on, she brutally massacres all the scientists. However, considering how much they deserve it...
Split Personality: Played with. Her Wretched Egg "personality" first appeared for her to deal with the trauma of being experimented on as a child. If Chapter 55 is anything to go by though, there was never a split personality to begin with.
Split Personality Takeover: Played with. In the later chapters of the manga, her Wretched Egg "personality" supposedly takes complete control and we don't see her more tender, child-like side reappear for a while. Chapter 55 reveals this to not be the case. In her own words: "It's the same as that coin you have. From two identical faces... there is only one Shiro."
Stepford Smiler: Her bubbly, happy-go-lucky personality turns out to be a facade. She knows full well that she is also The Wretched Egg, and feels utterly broken because of it.
Chapter 55 brought this Up to Eleven. She resents Ganta for being able to live a privileged life while she was stuck in Hagire's hellish experiments. She thus went after Ganta's school to express her sheer jealousy to her childhood friend.
Badass Normal: Is the only one of the main characters who isn't a deadman, but uses his kleptomania to disable a giant terrifying robot and is a very cunning liar.
Big Brother Instinct: Yoh is in Deadman Wonderland to earn the freedom of his sister, Minatsuki, who killed their father.
Brother-Sister Incest: Minatsuki accuses him of this on a regular basis after her fight with Ganta. This is even Played for Laughs. It's otherwise left ambiguous as to whether there is any substance to those claims.
The first Deadman who Ganta meets, Senji is known as Crow. He uses his Branches of Sin to form blades extending from his forearms. Enjoying a good fight, Senji supports Ganta after he defeats him in a fight in the Carnival Corpse.Tropes associated with Senji:
Tattooed Crook: He has the initials DSMK tattooed above his right eyebrow, which represents the names of his dead friends in the police force.
Took a Level in Badass: He was already a badass, but when confronting Mockingbird, who has dozens if not hundreds of powers, and his two agile, gun-wielding guards, Senji is able to hold off all of them with his close range blades, eventually killing the guards and giving Mockingbird a hell of a fight. This after being trashed by the Mockingbird earlier.
Yoh's sister, also known as Hummingbird. A Combat Sadomasochist, Minatsuki is a bit of a psychopath and enjoys harming others, caused by the abandonment of her mother during the Tokyo earthquake ten years ago. Yoh looks out for her, although she believes he is obsessive. She has a fondness for flowers, and her Branches of Sin extend from her hair.Tropes associated with Minatsuki:
Fridge Logic dictates that there probably isn't, with her accusations being a way for her to "rationalize" Yoh's caring for her to fit in with her trust and attachment issues: "I betray people before they can turn on me."
Chained by Fashion: Goes around with her wrists loosely chained together for no apparent reason. Evidence seems to suggest it's because she likes it.
Cluster F-Bomb: When her first episode was aired on Toonami, there were twenty-two censor bleeps. Nineteen came from Minatsuki. Although even Leah Clark was surprised "Why don't you jack off in a bottle of formaldehyde and call it our firstborn?!" made it through unedited.
Combat Sadomasochist: Gets off on the feelings of pain and betrayal she causes in others. She's not totally uncomfortable with being hurt herself, either.
Combination Attack: Did one of these with Peacock: A thorn-covered whip they used against Uzume Sumeragi. Yes, it's as badass as it sounds.
Evil Counterpart: To Ganta. Ganta was framed for a murder he didn't commit, while Minatsuki was convicted of murder for a clear-cut case of self-defense. They were railroaded by the same court and the same crooked defense attorney. Both were abandoned by their mothers. The difference? Minatsuki reacted to all this by becoming completely insane. Becomes Fridge Horror when you consider that Minatsuki has been in Deadman Wonderland in general and G-block in particular a lot longer than Ganta, and so it's a distinct possibility that Ganta is headed down the same road and it just hasn't set in yet.
A key difference between Ganta and Minatsuki, though, is Minatsuki was already crazy before coming to Deadman Wonderland due to the trauma with her mother leaving her to die. This shows in both her admitting to Ganta that she was crazy before she came to Deadman Wonderland and that she lied to her brother about her Dad raping her, so that her brother would kill her father. Her reason? A mixture of For the Evulz and the fact that she gets off on betraying, manipulating and being cruel to others. Granted, this past is highly questionable due to Minatsuki being an Unreliable Narrator.
Evil Cannot Comprehend Good: She goes ballistic upon learning that Yoh knew she was lying all along, and still cared for her as a sister.
The Fake Cutie: Was this in the beginning, until she dropped the act all together.
Freudian Excuse: During the earthquake, she was shaken off and abandoned by her mother as their home collapsed around them. Taken Up to Eleven in the anime, where her mother turns around and picks up a shattered pot of friggin ""primroses"" right next to where she's trapped under a pile or rubble and runs off with the flowers.
Genre Savvy: Acts like an innocent Damsel in Distress in order to get a wannabe Knight in Shining Armor (like Ganta) to protect her and go easy on her if they are picked to face her. So when she drops the act and literally stabs them in the back, they won't see it coming. It's not the first time she's pulled this particular gambit.
Innocent Flower Girl: Inverted. She acts shy and sweet and grows flowers, but her nice personality is just an act.
Lovable Sex Maniac: A more deadlier version. In her fight with Ganta, she says she gets off by looking at the faces of people in pain. But she seems to have stopped this.
Makes Us Even: In the anime, she repays Ganta for having the Penalty Game rigged to let her off with a haircut instead of the usual Organ Theft by slaughtering a squad of Undertakers after they cornered him while he was en route to the confrontation with Genkaku. She makes it clear that this doesn't mean she wants anything to do with Scar Chain, and only did this because she felt like she owed him. This didn't happen in the manga.
Moe: Invoked; Minatsuki introduces herself as the perfect moe archetype at first, small, shy, cute, meek, virginal, and afraid to hurt a fly. This is inverted when she reveals that the whole "moe" act is just a facade, and that she's really a sadistic sociopath who likes fighting, can and will kick your ass and torture you to turn her on, and is, on the whole, a Combat Pragmatist who is really not inexperienced with pain. Even after her defeat with Ganta and she mellows out a bit, you still only piss her off if you have a death wish.
Mommy Issues: Her cruel nature comes from her mother leaving her to die in the Great Tokyo Earthquake.
Never Be Hurt Again: To keep anyone from abandoning her the way her mother did, she deliberately acts as crass and cruel as she can so that no one will ever get close to her.
Traumatic Haircut: Lost most of her hair during a Penalty Game after losing to Ganta.
Unreliable Narrator: Minatsuki lies a lot, using her lies to get sympathy often. This puts her past into question quite often.
Villain Decay: More or less dropped all antagonism after Ganta defeated her in their fight, and joins the heroes in their ventures afterwards. All of her more disturbing traits are increasingly downplayed, as well.
Combination Attack: Does this with Minatsuki against Uzume Sumeragi, one of the Complete Forgeries. They combined their Branches of Sin to create a whip covered in thorns, and promptly handed her ass back to her just as she was about to use her finishing move.
Epic Flail: Peacock's Peak, her Branch of Sin. They resemble miniature morning stars.
Femme Fatalons: Averted. She has long nails, but she's not a bad person.
Known as Condor, Idaki claims all of his actions are told to him through his dead daughter who "speaks" to him through the headphones he wears. He believes he is responsible for his daughter's death.Tropes associated with Idaki:
The chief guard of the prison, Makina takes nonsense from nobody and is more than willing to wound an inmate who gets on her bad side. She has a firm disliking for Tamaki, and investigates the true purposes of Deadman Wonderland.Tropes associated with Makina:
Handicapped Badass: Wheelchair-bound after fighting Wretched Egg. She gets better in the epilogue, though.
Heel-Face Turn: Surprisingly, her simplistic view of justice allied her with the heroes, instead of against them.
Hero of Another Story: Her Knight Templar tendencies forced her to try and uncover the conspiracy surrounding Deadman Wonderland on her own from the other side of the fence, as it were.
Jerk Ass: In her introduction she is harsh to the inmates and (non-lethally) slices Yoh's chest when he interrupts note and also because she caught him stealing Ganta's candy and he wouldn't admit to it when she ordered him to give it back. However, her rather one-dimensional view of justice inadvertently sided her with some of the more moral prisoners against the warden, after which she was a useful ally. She just kind of settled down after that.
Kaiju Defense Force: Formerly a JGSDF special forces soldier. She learned how to use a katana from her time there.
Mysterious Past: The anime gives away one hint about her background during the closing credits: she's shown as a student at Nagano Middle School, with Idaki as her teacher and Rokuro as a fellow student.
Nice Girl: Especially when compared with her boss and the other guards.
The childish but intelligent assistant warden and promoter of Deadman Wonderland, Tamaki believes he is the mastermind behind the prison and its secrets. A Villain with Good Publicity, Tamaki is seemingly allowed to get away with all of his vile actions due to his status... for a while.Tropes associated with Tamaki:
The true antagonist of the series. Toto Sakigami, or Mockingbird, has been missing since he won the previous Carnival Corpse tournament but reappears claiming to know Shiro. Seemingly a nice guy, he is actually evil, with a diet of Branches of Sin.Tropes associated with Toto:
Adorkable: And at the same time, incredibly creepy.
Deadly Upgrade: For the final battle, Hagire installs caps all over Toto's body that allow him to hemorrhage blood with little effort, turning him into a walking armory of Branch of Sin. He loses blood at such a high rate that he's practically mummified himself before the other Deadmen finish him off.
Dead Person Impersonation: A lot of people actually did think he was Toto Sakigami for a while, although they noticed the drastic change in his personality before realizing he was Hagire.
He could also very well be an expy of Franken Stein, albeit an even more psychotic version of him. They even have the same thin features and glasses, at least when Hagire was in his original body, as well as the same compulsive need to dissect things... including themselves.
Hagire, however, could definitely be considered one to Chan and En, and arguably to a lesser extent, Shiro (after Sorae's death) as well. He just won't be winning any Father of the Year awards any time soon.
Power Copying: After doing it enough times, it more or less resolves into an all purpose Shapeshifter Weapon made from his blood anywhere on his body. Wings, tentacles, blades, wings made out of blades, etc.
Though, there are a few he can't copy; specifically, Ganta's Ganbare Gun (though he can copy the original ability, Ganta Gun), and Shiro/Wretched Egg's Branch of Sin. Word of God also stated he wouldn't have been able to copy any of the Forgery Branches of Sin in the series' guidebook, The Irational World.
Rasputinian Death: In his first showdown with the Deadmen, he loses two limbs. At the start of the final battle, he's a hobbling, dessicated shell that spews weaponized blood in all directions. Finally, he's whipped into the air, Frankensteiner'd onto a bed of spikes, lit on fire, and then blown to shreds by Ganta's enhanced Ganta Gun.
Self-Surgery: Does this an awful lot. There's a reason the seams and stitches all over his body are eerily similar to those of Shiro, and why he exhibits many of the same symptoms she had early on in her experimentation...
Theres No Kill Like Overkill: Deservedly ends up on the receiving end of this in chapter 53. Nearly every member of Ganta's crew has their fun beating the bastard to a bloody pulp before Ganta fittingly deals the finishing blow.
What Is This Thing You Call Love?: Toto doesn't shut up about it. Hagire doesn't understand the concept at all, but mentally associates it with violence against Shiro - hence why his ultimate goal is to get a body that can fight and kill her over and over again until he knows what it is.
Yandere: Hagire, to Wretched Egg. To an obscene degree.
Battle Axe Nurse: The good variant, of course. Though her friends think the occupation is at odds with her nature, her aspirations to Proper Lady-hood would make it an obvious career choice. The "Battle Axe" part is sadly just Karako being herself.
Oddly enough, in practice she appears to be an expert trauma surgeon, despite being specifically noted to be a nurse.
Good Old Fisticuffs: Her Branch of Sin hardens her blood around her hands and feet, giving her blows increased strength.
Good Thing You Can Heal: Not quite in the same way Shiro's Healing Factor works, but after she was stabbed by Genkaku, she used her Branch of Sin to crystalize the blood caused by the wound, stopping the bleeding and most likely saving her life.
Number Two: To Nagi. Before becoming the Number One.
Proper Lady: Likes to claim to be one, though most people beg to differ.
Super Toughness: She's able to use her Branch of Sin for defensive purposes, covering herself in crystallized blood, giving her a shiny, defensive coat reminiscent of Emma Frost. It's not clear just how tough it is, though she can apparently survive being doused in boiling acid sprayed by Necro Macro with it and walk away unscathed.
Fake Memories: Averted oh so cruelly. During his torture, Nagi screams that the memories of him going on a rampage were planted by Genkaku's injections, but they weren't. He just repressed them under stress. The drugs actually brought out the real memories.
Made of Iron: Survived Hibana's little ling chi session and ripped out his left arm once it's slice off with little to no reaction. Might be a hint that he's a lot tougher than he looks, with that Superpowered Evil Side locked inside him.
Unstoppable Rage/Roaring Rampage of Revenge: Had an incident like this after his wife was killed, and after Genkaku reveals that he not only killed Nagi's wife, but also their unborn child, he goes on another one.
Master of Disguise: He was the one who posed as Ganta in the leaked video in the first episode, which made everybody in the courtroom want to kill him. Maybe. Rokuro is seen to be very capable of editing footage, so he might have just digitally fabricated this.
Mood Whiplash: And how, at first he acts calm in episode ten but then he completely loses it in under five seconds.
Obviously Evil: Well, given that he was pretty mean to Ganta right off the bat, and that he shows his true colors as soon as things don't go his way, you'd think someone would of suspected him of something earlier.
Villainous Breakdown: He did not take the sight of survivors very well, mainly because it messed up his calculations. It gets even further when Senji showed up and threw his math off even further by improvising a move to bypass the Worm Eater.
What Happened to the Mouse?: In the anime he's left in the Scar Chain hideout, and is never mentioned again, while the manga he's seen on a bus leaving the prison...but is never seen or mentioned again. Not even the ending.
Leader of the 1st Undertaker Platoon. A self-proclaimed "super monk", he kills people under the belief it will free them from their suffering. He wields a guitar which doubles as a pair of machine guns.Tropes associated with Azuma:
Hey, It's That Voice!: His English voice is done by the same guy who voices Claude Faust from Black Butler. This becomes hilarious when you realize that his love interest is voiced by the guy that plays Sebastian Michaelis from the same series.
Impossibly Cool Weapon: He has a freaking guitar that can turn into two machine guns. It later gets upgraded to point where it can blow a football-sized hole through a man's torso. Spine included.
Save the Villain: An interesting variant. In the anime, taking a Ganbare Gun to the face is probably preferable to what almost happened to him considering he's confirmed alive in the manga; right before Ganta's Marked Change, Shiro went Wretched Egg, and would have slaughtered Genkaku and probably everyone else in room except Ganta had he not taken the initiative... without realizing what had just happened to Shiro, of course. This didn't happen in the manga.
Abusive Parents: Her mother was a psychotic cult member who inflicted downright hellish punishments on her for minuscule things like bedwetting and vomiting, and would abuse her for just about anything simply because she could. She completely deserved her death at the hands of her own daughter.
On the other hand, the ending credits in the anime seem to indicate that her father might not have been such a bad guy.
Obliviously Evil: She doesn't actually understand the concept of proportional response. All that torture she endured from her mother convinced her that extreme acts of violence were the appropriate punishment for misbehavior.
Broke Your Arm Punching Out Cthulhu: Delivered a successful Snake bite to Wretched Egg. Even though it didn't really do anything to her due to her Healing Factor, it still made her hesitate. Wretched Egg then curiously asked Azami if she really was Ganta's friend. Right when it looked like Azami might actually be getting through to her... Hagire decapitates her and asks what's taking Wretched Egg so long.
Cool Mask: ... well, at least it looks cool. What it actually does isn't cool at all.
A Deadman, and the 'older sister' of Toto Sakigami in G Block. She is neither related to, nor even older than Toto. She takes part in the mission to return to Deadman Wonderland.Tropes associated with Yosuga:
Anti-Villain: Types II and IV. She doesn't agree with Hagire's goals - and in fact makes it pretty clear she doesn't like Hagire himself at all - but damn it, she is not going to let her 'brother' die, and wants nothing more than to have her Toto back.
Brother-Sister Incest: Played with. She tells Ganta she was in love with Toto, but despite them having 'adopted' each other as surrogate siblings and are for all intents and purposes serious about it, they're Not Blood Siblings.
Death Seeker: Prior to becoming Toto's new official 'Nee-chan'. To the point where she actually questioned if her Branch of Sin was keeping her alive against her will.
Although, she does point out that Hagire didn't completely rewrite Toto's personality, and still has many of his mannerisms. And the fact that he didn't just attack her on sight like he did pretty much everyone else who set foot in Deadman Wonderland speaks volumes.
Thicker Than Water: Somewhat subverted in the sense that Toto isn't really her brother. Her entire motivation for returning to Deadman Wonderland was to protect Toto from the other Deadmen despite knowing full well why they felt he needed to be stopped. Even though he's Hagire now, she believed until the very end that her Toto was still in there, somewhere.
A pair of Creepy Twins who work for the Director. Both are Deadmen.Tropes associated with Chan and En:
Brain Uploading: Their Branch of Sin lets them do this. Prior to Hagire turning them into cyborgs, the damage they did to Japan's electronic infrastructure made the government think they were being targeted by professional cyberterrorists. Utilizing their Branch of Sin in this way was also how Hagire was able to Body Surf.
Cyborgs: Their backstory showed that they were born with half a brain each, and the only reason they were even alive (despite being in a vegetative state) was due to their Branch of Sin compensating for their missing brains. Hagire took them in, and gave them a cybernetic implant to replace the missing halves of their brains via their Branch of Sin. This caused them to become Single-Minded Twins, and is also the reason for their Undying Loyalty.
Dance Battlers: In terms of combat, they're some of the most acrobatic fighters in the entire series. What's more, due to them having a single mind, their attacks were perfectly synchronized with one another, making them able to attack from multiple directions at once. However, Senji was able to exploit this, because their synchronized style of fighting also made them predictable.
Transferable Memory: Their Branch of Sin was the key to Hagire's Body Surf tactic. They essentially linked Hagire and the victim to a type of computer, and then downloaded Hagire's memories into the new body, essentially rewriting their personality with Hagire's. Though it was later revealed that this method wasn't COMPLETELY flawless...
Motherly Scientist: When she was alive. Specifically this to Shiro while growing up, being one of the only people to treat her like both a little girl and a person. Sorae also seemed to be the only scientist that Shiro sort of liked.
Without the mask. Didn't see THAT coming, did you?!
The true identity of the Red Man who killed Ganta's classmates and the origins of the Branches of Sin. The other side of Shiro's personality, created through brutal experiments on Shiro as a child, her unlocked power causing the Tokyo earthquake.Tropes associated with The Red Man:
Blood Knight: Played with. She makes it seem like this was her sole motivation for her partnership with Hagire, stating that he can fully satisfy her bloodlust and desire for chaos and destruction, despite the fact that Hagire is one of the two main reasons she suffered so much in her childhood. In reality, she literally needed him, because he was her best shot at shutting down the Mother Goose System.
Fan Disservice: Depicted naked more than once in the Return to DW arc, though the context under which it happens takes a lot away from the scenes.
Fille Fatale: Shows shades of this towards Hagire in Chapter 43. The fact that she tolerated being touched by him as much as she did, while naked, says a lot, though it's seriously doubtful she's doing anything beyond simply using what she knows Hagire wants in exchange for shutting down the Mother Goose System.
From Bad to Worse: After Hagire's death, she destroys the MacGuffin that powers the Mother Goose System. The one thing restraining her full power is now gone.
Green-Eyed Monster: The reason she killed Ganta's classmates is because she was jealous of them.
Pet the Dog: A heartwarming (if curious) moment happens in Chapter 55. Even though she loathes sweets, the Wretched Egg also knows that her Shiro personality loves sweets and misses Ganta. She consumes the unfinished pudding, making Shiro believe that Ganta visited her cell while she was out.
Power Floats: Appears to be the only Deadman capable of flight without a Branch of Sin that involves wings.
Suicidal Cosmic Temper Tantrum: The Great Tokyo Earthquake was her trying to use her Branch of Sin to such a degree that it would destroy her own body faster than it could regenerate. Subverted because, obviously, it didn't work.
Super Empowering: The source of the Nameless Worm that gives deadmen their powers.
Superpowered Evil Side: Played with. Turns out it was just Shiro expressing her masqueraded resentment for Ganta and her thirst for revenge against those responsible for her experimentation all along.
Woobie, Destroyer of Worlds: Once you consider her backstory, she is most definitely this. Even Ganta seems to agree, according to Chapter 54. Their Ferris Wheel Date Moment has Ganta apologizing profusely for not being there to save Shiro, and it ends with him promising to 'end her suffering.'
Worthy Opponent: Seems to view Ganta as one. Most likely because she remembers just how much of a Determinator he was as a child, actually proving her wrong when she called him weak. Keeping in mind her insane cynicism borne of endless torture, Ganta was probably the only spark of humanity that ever got through to her. Though it inspired fascination more so than hope.
Oh, it inspired hope, too. Chapter 55 reveals that Ganta's unique Branch of Sin was actually designed by Sorae, and that it's the only Branch of Sin that is capable of killing her.
Yandere: Flat out admitted to Ganta in Chapter 55 that the only motivation for her butchering his entire classroom was sheer, unadulterated jealousy.
