    Diclonii in General 

A race of pink-haired superhumans with horns, who have the ability to extend telekinetic vectors. Because of their powers, they are feared by all humans.

  • Always Chaotic Evil: It's repeatedly stated in-universe that Diclonii are genetically programmed to hate humans and want them dead. Of course, how much of this is true is called into question by the fact that many Diclonii only became that way because humans kept treating them badly.
  • Animal Lover: Diclonii are more friendly with animals than humans.
  • Ax-Crazy: A particularly violent Diclonius can wreak havoc using their vectors.
  • Badass Adorable: The majority of Diclonii are cute young girls, and their powers are extremely deadly.
  • Bee People: They have no physical insectoid traits, but their caste system works similar to a beehive. Their species consists of a single fertile queen (Lucy), a large number of sterile workers (Silpelits), and a single male drone whose only purpose is to fertilize the queen (Lucy's brother).
  • Because You Were Nice to Me: Although most Diclonii have been treated badly by humans and thus hate them, they can grow to care for and love a human who shows kindness to them. And if someone dares harm a human or animal that a Diclonius has bonded with...well, a very messy death is most likely in short order.
  • Bizarre Alien Reproduction: Diclonii reproduce by infecting human males with their vectors, causing any children he sires to be Silpelit Diclonii.
  • Horned Humanoid: The distinguishing feature of a Diclonius is a pair of white horns that resemble cat ears.
  • Human Subspecies: The Diclonii, or Homo Diclonius, are the result of mutant ovaries. They have neko ear-like bone horns and enlarged pituitary glands; besides that, they're a cross between humans (most of what they are), social insects (for Silpelits in how they age), viruses (how they reproduce, for the most part) and gods (the vectors).
  • Mind over Matter: All Diclonii have telekinetic vectors, invisible hands that they can use for various purposes. That purpose usually involves killing humans.
  • One-Gender Race: Only female Diclonii are ever seen, and the Diclonii Research Facility reports that Diclonii can only be female. This is ultimately subverted with the introduction of Lucy's half-brother, the only male Diclonii in existence. The only reason he's male is because he shares a mother with Lucy and was born as a fertile Dicolinus who ages normally, unlike the sterile Silpelits.
  • Oni: Several of their motifs are based on the mountain beast. There's obviously the horns and monstrous strength (albeit as vectors), but they also follow Oni conceptually: Oni are described as the antithesis of humanity and are born when a human gives in to their evil desires, and thus are Always Chaotic Evil. Diclonii give in to their murderous desires and too can never go back to normal, and are fundamentally against humanity.
  • Our Elves Are Different: Being that the series is called Elfen Lied ("elf song" in German), Diclonii have some traits of fantasy elves, being a mysterious, superpowered, beautiful and inhuman race that turns children into their own species. Even their horns are evocative of the traditional pointy elf ears.
  • Then Let Me Be Evil: Diclonii are mistreated and considered monsters by humans because of their destructive abilities. This usually leads to them becoming human-hating Omnicidal Maniacs.
  • Unskilled, but Strong: Most Diclonii have no knowledge of fighting techniques. They have little need of them when they have the ability to rip people apart in the blink of an eye.
  • Touched by Vorlons: When a male human is infected by a Diclonius' vectors and then goes on to impregnate a female human, the result is a Silpelit Diclonius.
  • Traumatic Superpower Awakening: Many Diclonii only realize they have vectors after they use them to kill someone, accidentally or not. At one point in the manga, a special response team arrives at a home and finds a severed human head in the basket of a tricycle, next to a crying three-year-old Diclonius. They're forced to gun her down after her vectors rip a policeman apart.
  • The Virus: If a male human is infected with the Diclonius virus, any children he fathers will be Silpelit Diclonii. This is the Diclonius' primary method of reproduction.
  • Woobie, Destroyer of Worlds: The majority of Diclonii have been mistreated and abused by humans, and are prone to lashing out in destructive fits with their vectors as a result.
  • Younger Than They Look: Silpelit Diclonii age twice as fast as humans.

Maple House Residents

    Lucy & Nyu 
Voiced by: Sanae Kobayashi (JP), Kira Vincent-Davis (EN, series), Carli Mosier (EN, OVA), Alondra Hidalgo (Latin American Spanish)

The main character of the series.

General tropes

  • Adaptation Dye-Job: Somewhat. In the manga her hair is bright pink, but the anime has it as a notably darker shade of pink. Also, in the manga she has green eyes, while the anime gives her red ones.
  • Animal Motifs: Bovines. Nyū sounds similar to gyūnyū, which is milk in Japanese. An alternative word for the Japanese word ushi (meaning cow) is gyū, which Nyū's name also sounds similar to, and milk comes from cows. Being that it's also a slang word for breasts, this also alludes to Nyū's tendency to grope people's breasts, and her often appearing full-frontal naked. Additionally, during her childhood, the bullies would call her an ox due to her horns. It's also worth noting that that Satan is typically depicted as having red skin and bovine features, and is also the patron demon of the Sin of Wrath, which its representative animal is the bull.
  • Artistic License – Biology: Lucy/Nyu's nipples are placed very inconsistently; they're always somewhere on her breast, but "where" depends on the artist.
  • Betty and Veronica: Veronica (darker, dangerously unstable, and telekinetic mutant) to Yuka's Betty (lighter, sane, and normal human). Kouta has feelings for both, but he could never hope to have a normal, peaceful romance with Lucy/Nyu, unlike with Yuka.
  • Blonde, Brunette, Redhead: In the manga, she's the redhead (although her hair is closer to pink) to Mariko's blonde and Nana's brunette (purple hair).
  • Body Horror: Towards the end of the manga, her body starts decomposing due to overusing her powers. Before Kouta kills her, she has been reduced to a pile of goo.
  • Cute Monster Girl: Her horns look like cute cat ears. Tragically deconstructed.
  • Forgotten First Meeting: Kouta initially met her in his childhood after she killed her first victims. Unlike everyone else, he found her horns fascinating and forged a strong bond of friendship with her, thus keeping her murderous Diclonius instincts repressed. However, he erased her from his memory after she brutally killed his father and sister right in front of him because he neglected to specify his cousin's gender.
  • Godiva Hair: Her hair is sometimes depicted this way.
  • Good Angel, Bad Angel: Near the end of the manga, Lucy vehemently rejects the advice of her DNA personality, who has been suggesting to her to exterminate humanity since she was a child. She even states that subconsciously, Nyu has been telling her they can live peacefully with humans ever since Nyu was first created as a personality.
  • Good Eyes, Evil Eyes: Just contrast the innocent Nyu persona's wide, bubbly eyes with the narrow, hateful, tortured eyes of the Lucy persona. It's notable that Lucy's often drawn with nearly the same soft, cutesy expression as Nyu when she's around Kouta, at which point the audience (and Kouta) can only figure out that something's up when Nyu suddenly starts speaking coherent sentences.
  • Hide Your Otherness: She's occasionally given a head accessory like a hat or ribbons to hide her horns.
  • I Cannot Self-Terminate: Toward the end of the manga, the Lucy/Kaede and Nyu personalities beg Kouta to kill her now that her homicidal Diclonius instincts personality has finally taken over, and she must depart their ruined body, leaving the DNA voice in control, not to mention agony.
  • Important Haircut: Lucy/Nyu chops off her hair in order to impersonate Kouta's younger sister Kanae, which signifies Lucy's guilt over murdering her. Coincidentally, it also makes her resemble her younger self.
  • Interspecies Romance: She is a Diclonius and Kouta is a human.
  • Light Feminine and Dark Feminine: Nyu is the Light Feminine (innocent, childlike, and cheerful), Lucy is the Dark Feminine (cynical, cold, and murderous).
  • Literal Split Personality: At the end of the manga, the Lucy and Nyu personalities appear to become two separate people after reincarnating, as it's implied they're the twins Kouta's daughter is friends with.
  • Monster Roommate: A mass murdering superhuman with horns and invisible telekinetic Combat Tentacles ends up crashing at a random family inn owned by Kouta and Yuka, although they aren't made aware of it at first.
  • Ms. Fanservice: Just about every other scene has her showing off her fairly toned figure.
  • Naked First Impression: Kouta and Yuka find Nyu naked on a beach. This is averted for Kouta, however, as he first met Lucy when they were younger.
  • Naked on Arrival: She's completely naked save for a helmet as the series opens.
  • Only Known By Her Nickname: The names "Lucy" and "Nyu" were given to her by other people. It's until the end of the manga that we find out her real name; Kaede.
  • Power Makes Your Hair Grow: Manga only. After the Time Skip, Nyu has shoulder-length hair. The first time Lucy awakens after the Time Skip, her hair grows and reaches her back. It stays at this length for the rest of the series.
  • Reincarnation: In the manga epilogue, it's implied Lucy/Kaede and Nyu are eventually reborn as twins and reunite with Kouta years later.
  • Split Personality: One has the mental capacities of a small child, the other's an insanely powerful killer out to take out a significant portion of humanity. She holds the current page image. There's a third personality that acts as a personification of her basic, murderous instincts, which was named The Voice by Lucy.
  • Split-Personality Switch Trigger: The switch between Lucy and Nyu and back is triggered by either a nasty injury (usually a blow to the head) or a very traumatic memory.
  • Split-Personality Takeover: The shift between Lucy and Nyu; Lucy knows when Nyu has been in control, but doesn't try to stop it from happening. Add in Kaede, her original personality, and the DNA Voice, which only takes over at the end.
  • Star-Crossed Lovers: She and Kouta have... so many issues between them that it's a miracle they still love each other at all.
  • Tragic Dream: Her love for Kouta extended to wanting to marry him, which Kouta only finds out towards the end of the final chapter years after her death in the letter she left for him.

Warning! Unmarked spoilers from this point onward!

Lucy has 4 vectors in the anime and around 12-15 (though one panel near the end shows her with 28) in the manga with a limited range of two meters. However, she demonstrates prodigious control over her vectors and can be swift and lethal within that range in addition to being able to use nearby objects as high velocity projectiles to kill at greater distances. She is also capable of stopping or deflecting most standard ammunition. Her great skill and murderous intent have caused her to be regarded as the most dangerous of the Diclonius.

Lucy hates humans mainly because of how she was treated by her human peers as a child. Consequently, she discounts non-Diclonii, claiming they are not real people, to the point of stating that she has "not killed anyone yet". She seems to lack empathy, kills without much concern, and acts sadistically. Despite this lack of concern for human life she will not harm Kouta, as he was her only childhood friend.

  • Adaptational Badass: Played with. While certainly powerful and competent, Lucy in the manga is as likely to kick ass as she is to get her own ass kicked and usually relies on clever tricks or diversions to get the upper hand. Her anime counterpart however seems to bulldoze through everyone casually without the slightest bit of effort, only meeting her match with Mariko. The difference is that most of her anime counterpart foes end up being a lot weaker or less competent than their manga counterparts and the fact that even before her vectors get longer, manga Lucy has shown more vectors and a much more vicious and merciless nature.
  • Adaptational Nice Guy: Heavily Downplayed. While still a murderous Villain Protagonist, Lucy is considerably less sadistic and Ax-Crazy in the anime than in the manga, where she was prone to Evil Laughs and Slasher Smiles while literally tearing people to shreds.
  • Aloof Big Sister: She kills her half-brother along with his father, Director Kakuzawa. It's a Mercy Kill, since her brother was born specially for impregnating her and he's controlled by Director Kakuzawa. She does express remorse over killing him.
  • And Your Little Dog, Too!: Inverted, Lucy does it to the antagonist and Kouta.
    • Played with early on when Lucy comes across Mayu's little dog, Wanta. She looks down at the dog, which is barking frantically at her but unable to run away because it's tied to a leash, and we're treated to what seems like a Gory Discretion Shot as we hear Lucy use her powers. When Mayu comes outside, the audience's expectations are subverted when it's revealed that Lucy actually cut the dog's leash. It's our first hint that Lucy's not as bad as she seems, or at the very least, sees lines that she absolutely will not cross.
  • Animal Lover: She rarely shows open affection to humans or animals, but will absolutely not kill the latter; her personal tragedy with her own puppy in childhood likely reinforces this trope for her.
  • The Antichrist: A near-literal example because of her horns and her name being the female version of Lucifer, a demon.
  • Anti-Hero: Part of her Character Development involves graduating into one, both in the anime and manga. Says a lot about the series that being an Anti-Hero is preferable to what she used to be at the beginning.
  • Ape Shall Never Kill Ape: Subverted with Nana when the latter tries taking her back to the research facility. She admits that she didn't really want to kill another Diclonius and tried to simply let her off with a warning, but that goes out the window when Nana refuses to back down, and she ends up gleefully turning poor Nana into a quadruple amputee and only stops short of killing her thanks to outside interference. Since every Diclonius she fights (including Nana) is working for people trying to recapture her, this reluctance never really comes into play.
  • Apocalypse Maiden: Toward the end of the manga, her homicidal Diclonius instincts personality finally takes over and starts killing humans everywhere on the world at rates that would make the deadliest WMDs look like mere fireworks in an attempt to destroy humanity in a spiteful decision that since Diclonii, and mainly her, can't rule the world, she'll destroy it.
  • Arch-Enemy: To Kurama. At first, he (reluctantly) follows orders to have her recaptured by the facility rather than killed, but that changes pretty soon. Partially to end the threat he recognizes that she poses to the world, but also because Lucy is paying him back in blood for Aiko's death, killing his secretary, dismembering and almost killing his adopted daughter, and (in the manga) being the reason for Mariko's death, and then directly killing two of her clones in front of him.
  • The Atoner: As things go along, you'll find that Lucy really does regret her actions, and she tries her damnedest to make amends for it several points in her history, because ultimately, she's content to live with Kouta and would rather stop killing (hence why she doesn't do so in front of him). Unfortunately, this being Elfen Lied, fate just keeps trying to pull the rug under her feet anyway. At the very end, when she has her Superpower Meltdown, she atones in the only way she can - by convincing a very reluctant Kouta to Mercy Kill her.
  • Ax-Crazy: In the manga, Lucy doesn't just nonchalantly tear people to pieces, she does it with a huge grin on her face and a really Evil Laugh.
    • A point could be made that Lucy is simultaneously more and less unstable than she was in the past. While she now takes obvious joy in slaughtering humans, she doesn't randomly kill everyone she comes across unless they've actually wronged her.
  • Badass Adorable: When she starts defrosting, she builds up an immense reservoir of cuteness. And at the same time, she - at her weakest - is considered a terrifying killer capable of killing dozens of armed guards with nothing on. By the end of the manga she's capable of destroying islands, cities, and nearly taking out the entire planet.
  • Barbarian Long Hair: Meant to emphasize on how tough, murderous, antisocial and uncontrollable she is.
  • The Baroness: The Sexpot type but with the fear factor of the Rosa Klebb type turned Up to Eleven.
  • Because You Were Nice to Me: Kouta was the first person to treat her kindly and befriend her despite knowing she's different. Her days with him are her only happy memories, which is why Lucy fell deeply in love with him and he's the only human she refuses to harm.
  • Beleaguered Childhood Friend: She and Kouta were very close friends when they were kids. In the present, he has conflicting feelings about her since she's now a mass murdering sociopath in the run not to mention she's responsible for the deaths of his father and sister. In the end, he has to reconcile his lack of ability to forgive her with his lack of ability to hate her (no matter how much he says otherwise).
  • Blank White Eyes: In the anime, when her right horn gets ripped off during the fight with Mariko. She appears to be in shock or comatose for several minutes.
  • Blessed with Suck: She has powers far beyond that of any ordinary human, which unfortunately has made her a popular target for those who see her as nothing more than a monster to be slaughtered. As a child she hated her horns for making others view her as a freak of nature, and when pushed too far she let go of all reservations in using her unique abilities to kill anyone who dared to cross her. Unfortunately, this also had the dual effect of costing her the trust of the one person to treat her with genuine kindness, which leads to her single biggest regret in life. Suffice to say, even though she's a sadistic killer, Lucy hates what she was born in to.
  • Blinding Bangs: Another sign of when Lucy is in control; Nyuu's bangs tend to be parted whereas Lucy's tend to almost completely cover her eyes, taking on a dagger-like appearance as they conceal her face.
  • Blood from the Mouth: The initial signs of her Superpower Meltdown before she literally starts melting.
  • Blood Is the New Black: Frequently ends up being covered in blood after attacking people with her psychic powers.
  • Broken Bird: Treated like crap by most humans, bullied relentlessly during her childhood... yeah, Lucy's about as broken as it's possible to get.
  • Byronic Heroine: Morally neutral, to put it mildly. She's also largely concerned with personal interests, disrespectful of common authority, defined by conflict, and is a cynical, jaded, brooding, spiteful loner who has intense passions that drive the story.
  • Childhood Friend Romance: She has been in love with Kouta since her childhood.
  • Clingy Jealous Girl: Downplayed, surprisingly. Shortly after we see the flashback where she dips into mass murder out of jealousy, she smacks a vector in Yuka's face (probably the least harmful form of aggression she can display with her vectors) in response to seeing Kouta and Yuka holding hands, and when Kouta expresses concern for Yuka appearing to just fly backward for no reason, Lucy calmly accepts that he's "taken" and never even considers laying a finger (visible or invisible) on Yuka again.
  • Combat Pragmatist: Her vectors can't reach beyond two meters... so she'll just throw a boat at you, as Bando learned the hard way. Not to mention stealing the gun off of a dead soldier when he tries to shoot her from a safe distance, after which he looks like a deer caught in the headlights before she shoots him.
  • The Comically Serious: Some of her funniest moments involve her saying something either really snarky or really odd while in a complete deadpan. Some of it is played for Black Comedy.
  • Contralto of Danger: In her Nyu persona, she is like an innocent young girl. When she switches to her Lucy persona, she has a much lower voice to match her dangerous and threatening nature.
  • Curb-Stomp Battle: Any "fight" she takes part in, although this is reversed in the battle between Lucy and Mariko, but only in the Anime. And also completely Inverted in her second fight with Bando in the Manga. Averted by her duel with Nana, which is more or less an even match; Nana gets the advantage, but Lucy wins because she's far more willing to hurt Nana than vice versa.
  • Dark Action Girl: Fits both the "dark" and the "action" parts with emphasis.
  • Dark Is Evil: In the only other outfit she's most seen in, she wears a black teddy. Spells out that she's not a pleasant person.
  • Deadpan Snarker: A particularly cruel snarker. This exchange stands out:
    Nana: I'm not scared of you! It doesn't hurt at all!
    (Lucy rips off one of her arms, Nana screams in agony)
    Lucy: So does it hurt now?
  • Deconstructed Character Archetype: Of the Magical Girlfriend and Cute Monster Girl. For the former, her powers are negative in nature, being that they can dismember, infect humans, and nearly destroy the planet, and they also add to her ax-craziness. For the latter, her being different from the humans was what caused her to be persecuted, and said persecution ultimately drove her insane and made her into a killer.
  • Defrosting Ice Queen: Most of her arc in the anime. "Defrosting" also includes being slightly less murderous.
  • Desperately Craves Affection: It's her greatest strength and her Fatal Flaw, because it pushes her to commit atrocities if she felt betrayed.
  • Determinator: No matter how many people oppose her. She will find Kouta and she will apologize to him, and anyone who gets in her way will die. Horribly. Also, if your name is Kurama, don't ever let your loved ones near her. She will kill every last one of them. And there's nothing you can do to stop her.
  • Did You Just Punch Out Cthulhu?: Lucy "single"-handedly took out the giant precog monster Director Kakuzawa made Anna into.
  • Don't Make Me Destroy You: In her first meeting with Nana, Lucy initially doesn't want to fight her and tries to just scare her off, telling her to go home. When Nana persists, Lucy gives in and attacks.
    Lucy: I was going to let you go. After all, there aren't many of us out there. But you're just such a pain in the ass.
  • The Dreaded: Being a mass murdering girl who can rip apart armed soldiers and wants 99% of the people she sees dead will do that. Practically the only people who don't end up wetting themselves when she's near is Kakuzawa Senior who gets his head ripped off and Bando who gets mutilated. Though Bando at least is capable of putting up a good fight the second time.
  • Dull Eyes of Unhappiness: A trademark identifier of Lucy, in contrast to Nyu, is her dim and narrow eyes sadness.
  • The Eeyore: Particularly in the anime, where damn-near every moment of screen time has her as a Perpetual Frowner.
  • Escaped from the Lab: She escapes from the lab in first episode, taking out 23 guards in the process.
  • Even Evil Has Standards: She has no qualms against killing... but avoids committing such acts in front of Kouta as much as possible. She also doesn't harm animals, as seen in her interactions with Wanta.
  • Evil Cannot Comprehend Good: When she faces Nana for the second time, she is genuinely confused when Mayu hugs her in a desperate attempt to stop her from harming Nana, during which she pleads for "Nyuu" to stop fighting. It only stops her momentarily, but she at least does not harm Mayu for it. When she tries again to confront Nana, Mayu screams for her to stop, causing Lucy to revert back to Nyuu.
  • Evil Is Hammy: Loves setting up cruel Mood Whiplashes in particularly creepy ways, to the point where she may even be Trolling the readers. Loves laughing on the dead bodies of her victims. Always boasts and taunts about her power whenever she meets a foe she hates. And yet can somehow find a reservoir of cuteness whenever she's near Kouta and boast about why she loves him.
  • Evil Laugh: Manga-only. On some pages, it is rendered with an extremely thick font.
  • Evil Redhead: Though she is more specifically a hot-pink head, and it's more specifically her DNA Voice that's truly evil.
  • Evil Sounds Deep: Lucy's voice is low, deep, and quite ominous in comparison to Nyu's chirpy, childish, high-pitched voice.
  • Face Death with Dignity: In the anime finale, she shares a Last Kiss with Kouta before calmly going to face a Bolivian Army Ending, though the final scene implies she survived.
  • Fatal Flaw: Her desperate need for affection. She wants someone to love her so badly that if she even suspects a betrayal, heads will literally roll.
  • Fiery Redhead: She is one you would not want to provoke, or you would be dead.
  • Friendless Background: She spent her childhood in an Orphanage of Fear where she had no friends and was frequently bullied by the other children for her horns and emotionlessness. The one person who it seemed like she was gonna become friends with at the orphanage later betrayed her and sold her out to the boys that had been bullying her. She then made two more attempts to reach out to someone else and become their friend. The first ends with her feeling betrayed once again, while the second ends in her new friend being killed and her being captured. After that it's sort of understandable why she stopped trying.
  • From Nobody to Nightmare: In the backstory, she was a shy, kind-hearted Diclonii who lived in an Orphanage of Fear. Then, she eventually became a human-hating killer after her Start of Darkness.
  • Full-Frontal Assault: The fact that Lucy has nothing on but a helmet in the first scene of the anime does not stop her from taking on and killing dozens of soldiers as she fights her way free from a military facility.
  • Ground Punch: The manga has Lucy using her vectors to strike the ground in order to jump long distances, they even leave hand marks and small craters behind.
  • The Heavy: The DNA Voice, which cannot directly posses her, is the one who commands her, but she is the one directly killing people.
  • Hellish Pupils: Only in the manga, but she does not have them always.
  • Heroes Love Dogs: Well, not exactly a hero, but she clearly has a soft spot for dogs. It was the brutal murder of a puppy that she cared for that finally made her snap.
  • Heroic Self-Deprecation: Villainous version. She puts herself down very often, usually when it involves Kouta.
  • Hidden Eyes: Quite often, although very prominent when she's just reverted back to Lucy.
  • Human Shield: Used a poor office girl at the laboratory as one when she escaped. The girl didn't even know what was going on before Lucy ripped her head off.
  • Implacable Woman: Go ahead. Keep throwing shit at her. She will always plow through it to get to you.
  • The Juggernaut: Lucy's vectors can be used for defense and are capable of stopping really intense firepower. What's more, they are invisible at all but the highest frequency, so she can slowly stalk her latest target despite them emptying clip after clip against her.
  • Kick the Dog: Many, many times.
    • Slicing off Nana's limbs after the threat she posed was completely neutralized.
    • Trying to kill Mayu after Mayu tried to help her. However, this is partially negated by Lucy's own regret at even considering it.
    • Killing an entire family in a house, both so she could crash for the night and because she was jealous at how the family was having a happy life. This event was meant to really show just how bitter the world made her.
    • She keeps attacking Alicia and Barbara who are trying to save Nousou while they are helpless and she kills one of them. It's not like they didn't see it coming, since they took her home.
  • Kill All Humans: If it wasn't for Kouta, she would've done this long ago.
  • The Last Dance: Kouta has a fatal gunshot wound, Lucy's body is already at limits from a abortive attempt at avenging the aforementioned fact on a global scale, and JSDF air and maritime forces are already scrambling to take her out with their full firepower. What does Lucy do? She proceeds to sing the Elfen Lied poem while patching up Kouta's body on a cellular level and blasting the JSDF forces out of both sky and sea, ''simultaneously. She knows full well that she's going to end up with a fatal Superpower Meltdown.
  • Last Kiss: In the anime, Lucy kisses Kouta shortly before confronting the soldiers who have been assigned to kill her. Her fate, however, is left ambiguous.
  • Limp and Livid: Quite a lot. Whenever Nyu flips over to Lucy her head drops so her hair covers/shades her eyes.
  • Love Martyr: For starters, it was her love of Aiko that made Lucy subject herself to years of human experimentation - tantamount to a living hell, yet she was fine with it as long as Aiko survived... and when she was told Aiko didn't survive, Lucy was crushed. When she gets free, she spends the rest of her life trying to find Kouta so she could apologize for what she did to his family, even though she knows she can't atone for it. When that happens, and he flat out says that he hates her for what she did to his family, she still embraces him when he accepts her into his house in exchange for not killing anymore. When he takes the bullet for her from Kurama, it was her love of Kouta that drove her to heal him at the cost of a Superpower Meltdown.
  • Made of Iron: She survives taking an anti-tank slug to the head in the first episode. To be fair, though, the thing barely grazes her, she's wearing a helmet, and she has her vectors to protect her. She still does survive falling hundreds of feet off a cliff into the ocean without drowning immediately afterwards though.
  • Make It Look Like an Accident: On the occasions that Lucy feels like being subtle, she simply pops a vessel in the victim's brain or heart. However, her flashback with Aiko shows that Kurama was still able to track her down when an area had too many deaths by sudden heart attacks or cerebral hemorrhaging to be a coincidence.
  • Meaningful Name:
    • Can be seen alternatively as a female version of Lucifer (the devil, which fits her role as an evil mass-murderer), and also sounds like "lucid," which could refer to Nyu only initially talking in full sentences when Lucy is at the wheel.
    • Lucy is also the name of a protohomonid skeleton with an upright gait and small brain capacity, suggesting a missing link between the great apes and modern humans. Lucy, being the first of her kind capable of "proper" reproduction, could also potentially serve as a missing link between humans and some future Diclonius race.
  • Memento MacGuffin: Lucy's letter to Kouta. It also reveals her true name.
  • Monster Progenitor:
    • She's not the first diclonius by a long shot, but her vectors are capable of spreading the diclonius condition to the gametes of humans she touches with them.
    • And how can we forget that she's the only fertile female of her species.
  • More Than Mind Control: Turns out Lucy was Driven to Murder in part, by the manipulations of an Omnicidal Maniac Split Personality within her (born from either snapping at the constant abuse, her own genetic drive to Kill All Humans, or both).
  • Murder Is the Best Solution: If you even slightly irritate or wrong her in any way, shape, or form, you're dead. Justified to a degree, as her... not-so-happy life prompted this as a defense mechanism for her.
  • My Greatest Failure: Killing Kouta's father and little sister is perhaps the one murder she feels any guilt over, and clearly hates herself for the grief she caused him. She knows she cannot truly earn forgiveness for her actions no matter what she does, and indeed is brought to tears when confronted with this fact.
  • Mysterious Waif: It's what got Kouta and Yuka to adopt her into the family at first.
  • Nominal Hero: Given how completely messed up and outright evil many of the characters are and the fact that she is one of the main characters, Lucy can be seen as heroic at times. However, all she cares about is going to Kouta attempting to seek forgiveness from him (which fails) and although Kouta can maintain her somewhat stable when he's near her, she's perfectly willing to do horrible things to those who get in her way.
  • Not So Stoic: In the manga, whenever she's on a killing spree, she's happier than a kid high on weed.
  • Off with His Head!: More precisely, "Off With Their Heads!". Decapitation is her preferred method of killing people she hates. It's swift, fast, bloodless, and efficient. Everyone else (including Bando) fall under Ludicrous Gibs.
  • Omnicidal Maniac: Understandable, since she had been put through so much abuse that she gave in to the DNA Voice's orders to butcher all humans.
  • One-Woman Army: She's known for gaining a massive headcount.
  • Pay Evil unto Evil: Downplayed. Though she is more sadistic towards people who deserve it. She'll kill anyone, but she'll torture people like Bando half to death.
  • Peek-a-Bangs: She has one eye covered by her hair, though not when she's in her alternate personality Nyu, and not during flashbacks either.
  • Perpetual Frowner: In stark contrast to Nyu, Lucy almost always has a sullen and menacing frown unless she's with Kouta. An exception is reserved for when everybody else is unhappy.
  • Person of Mass Destruction:
    • An order of magnitude more dangerous than the other Diclonii, due to being fertile.
    • She also has the power to destroy the Earth. At the cost of her own life. Not that she matters much by the time she wants to put it into effect.
  • Pet the Dog: Her moments of compassion are rare, but very poignant, because it shows that she still has some humanity left in her fractured mind. As time goes on, both in the anime and the manga, the more these moments pile on, the more humanity ultimately returns to her.
    • The first instance that shows she still has a heart came in the form of her meeting Mayu's dog in a cage. While it looks like she killed the puppy, it turns out that she actually cut the rope that kept him restrained and allowed him to reunite with Mayu.
    • Lucy actually took the time to protect Mayu from a fight with another Diclonius, and that was when they first met. She literally had no reason to even acknowledge Mayu's existence, but she went out of her way to protect her anyway.
    • She may be a mass murdering sociopath fueled by her hatred of humans, but her ability to love is powerful. The shit that she allows herself to suffer through, purely for the sake of her loved ones, is her single greatest trait. See Undying Loyalty below.
    • Nothing will excuse her Kick the Dog moments, but she has shown that she can (and does) learn from her mistakes if given a chance. In particular, after the incident with Kouta's family, she refuses to kill Aiko's asshole dad purely because she'd rather not make Aiko sad; she encourages and actively tries to get Aiko to reunite with her mother; she offers to take the blame after Aiko accidentally killed her father; she doesn't commit infanticide after what happened with Kanae (and feels bad about trying it with Mayu so Kouta wouldn't have to relive his memories of Kanae); and she refrains from killing anyone in Kouta's presence, no matter how much she personally hates her targets.
    • She was surprisingly regretful at the idea of killing Mayu (most likely an attempt to keep Mayu from triggering Kouta's own memories as a result).
    • She hated her mother for all her life... but when she finds out the truth of what her mother went through, Lucy forgives her.
    • She clearly doesn't think much of Yuka, and would've killed her years ago if Kouta hadn't begged her to stop. When she and Kouta hold hands as she expresses concern over Nyuu's well-being, Lucy smacks her across the face with her vectors. Kouta helps her back to her feet and Lucy recognizes Kouta's love for his cousin, and from then on we don't see her ever try to harm Yuka again under any circumstances.
    • Her genuine grief over her murders of Kouta's father and sister. That was awful, but it was nice to see Lucy herself show remorse for once. She knows she can't fully atone for it, but she still wants to atone anyway, which says a lot about how much it was eating her up inside.
    • When she accepts his offer to stay with him on the condition that she doesn't kill again, it shows that, yes, she really would rather just stop killing altogether if it meant living a normal life.
    • When the Maple House is attacked, and Nyu holds off much of the invasion force, Lucy wakes up, and notices that Kouta had regained his memories of her killing his family. Perhaps resigned to the fact that she and Kouta could never be together, the first thing Lucy does... is to ask Nana to care for the Maple House and its residents. Furthermore, she even asks Yuka to take care of Kouta.
    • In the anime, after Kurama and Mariko's suicide, she tells Nana to live with Kouta, an act that leaves Nana completely baffled but nonetheless grateful. Somehow, Lucy found it in herself to abandon her animosity towards Nana, recognizing what she had come to mean to Kouta and expressing the hope that Nana, who was now without a home would be better family to him than she could ever be. Nana then becomes a permanent resident of the Maple House.
  • The Power of Love: At the very end, it is her love of Kouta that eventually enables her to beat her Enemy Within.
  • Pre-Mortem One-Liner: Before killing Tomoo and the orphanage boys in the backstory, Lucy says, "You know who's not human...? You know who's not human?! PEOPLE LIKE YOU!"
  • The Promise: Lucy and Kouta agree to meet at the stone behind the festival terrain on the last day of the summer festival.
  • Put the "Laughter" in "Slaughter": Whenever she's butchering someone, she's always cackling.
  • Red Eyes, Take Warning: In the anime. In the manga, they're green according to the cover art.
  • Rei Ayanami Expy: It could be said that she's a rather extremely dark take on the archetype. She has pale skin, unnatural hair and (in the anime) eye color, indeterminate origins, isn't entirely human, has a very cold demeanor (even after defrosting) unless she's killing someone, serves as a Love Interest to the main male lead Kouta, and is single-mindedly devoted to him. However, her single-minded devotion to Kouta had lead to deadly consequences for everyone involved. She also suffers a significant injury by getting shot in the head in the beginning, is the key to the Big Bad's plans, and, closer to the original take, serves as an Apocalypse Maiden in the climax. Will all of those facts, she's one of the few examples who actually stays true to the original character's Unbuilt Trope nature.
  • Retired Monster: Yes and no. By the time the series starts, Lucy has murder as the only option regarding humans, but she seems to limit her present-day killings to unsavory people. She does get better, though, ala Defrosting Ice Queen.
  • Sanity Slippage: A chapter dedicated to her childhood shows she got so unstable and murderous through this trope.
  • Satanic Archetype: She was considered a social outcast, having been abandoned by her parents since birth and born a diclonius and subsequently ostracized by many because of it, not unlike Lucifer being cast from the heavens. She is also the first and the Queen of her species, further strengthening her association with Satan. She even has the Biblical Motifs to go with it, such as being shot in the head but surviving parallelling the mortal wound to the head the Beast survived in the Book of Revelation. Aside from that, she has the pink hair, her name is Lucy, and she wants to rebel and destroy humanity. Even her Animal Motif goes hand-in-hand, as her representative animal (bovines) are used in contemporary depictions of Satan, and the bull is the representative animal of the Deadly Sin of Wrath, whose patron demon is Satan.
  • Sean Connery Is About to Shoot You: When Bando decides to kill Lucy by shooting the grenade next to his dead teammate, he forgot an important object: the teammate's automatic machine rifle. It went to hell from there.
  • Senseless Sacrifice: Before her capture (sometime after she killed Kouta's father and sister), she turns herself in as a final attempt to give humanity a chance and to save her new friend, Aiko's life. She later finds out when being bound in the very place first seen that Aiko died from her wounds and that practically drove Lucy to cross the Despair Event Horizon. The epilogue reveals that Aiko survived all along, which means Kurama had lied to Lucy and they were going to experiment her anyway.
  • Serial Killer: She's killed people ever since she was young, ranging from having a place to eat and sleep for a couple of nights to the person looking at her the wrong way. The news reports even label her as such.
  • Seven Deadly Sins: Lucy seems to embody them, as part of her being the series' squivalent of The Antichrist.
    • Wrath: Lucy is defined by her Unstoppable Rage, being hellbent on Kill All Humans.
    • Envy: Lucy has displayed intensely jealous behavior towards Kouta, and murders his father and sister to spite him for having seemingly left her for Yuka, and has contemplated murdering Yuka. Additionally, Lucy has killed numerous families because she was jealous at how they were living a happy lives while she was ostracized for her powers and appearance.
    • Greed: Lucy has killed numerous families so she can have a place to stay.
    • Gluttony: Lucy has murdered people excessively, well beyond her supposed targets.
    • Sloth: Lucy rarely does any work in the Maple Inn and is usually seen loafing around, instead having Nyu do the work.
    • Pride: Sees herself as superior to humans, and DNA Voice believes it has the right to lord over everyone else.
    • Lust: Lucy has shown to enjoy murdering and torturing her opponents far more than she lets on.
  • Shameless Fanservice Girl: Unlike Nyu, she does know that being naked is a problem, but she often has other things on her mind. Her conversation with Director Kakuzawa is the only time that she showed the urge to cover herself.
  • Shoot the Dog: It isn't clear if she truly meant to kill Mayu or if it was a fakeout by the author, but her closeness to Mayu after fighting Bando a second time suggests she meant to kill her.
  • Sibling Murder: In the manga, she has a younger half-brother, the first male Diclonius. Upon meeting each other, she kills him. She doesn't hate him, but she did it because their kind can't exist anymore and the fact he was being controlled by Kakuzawa, making it a Mercy Kill.
  • Single Woman Seeks Good Man: She falls for Kouta because he is the first person to be genuinely kind to her and not shun her because she is different (he even finds her horns cool). Even though she gets, to say the least, deranged and murderous later in life, she continues loving Kouta for his virtues and refuses to harm him.
  • Slasher Smile: When she's killing folks, but only in the manga.
  • Sociopathic Hero: She does show lack of regard for human life and has shown empathy for other people (namely Aiko) in the past, but by the time Elfen Lied starts, she's too far gone in her hatred of humans.
  • The Stoic: When outside of a fight, but mostly in the anime which takes away her Slasher Smile.
  • Stringy-Haired Ghost Girl: Tends to have this appearance whenever she reverts back to her Lucy persona from her Nyu persona.
  • Sugar-and-Ice Personality: Cold and deeply cynical, but only because she's been hurt so badly every time she lets her guard down. She can be very genuinely caring and insanely loyal towards those she becomes attached to. She may slaughter humans without hesitation or remorse, but her capacity for love is still very real.
  • Super Strength: In the manga, she rips Kisaragi's head effortlessly with her bare hands.
  • Superpowered Evil Side: She's it, except there's an even more evil side that's essentially her basic instincts.
  • Superpower Meltdown: Toward the end of the manga, Lucy goes into a literal meltdown due to abusing of her telekinetic powers while destroying some planes and then for saving Kouta.
  • Sympathetic Murderer: Even being a mass murderer with a penchant for Slasher Smiles and Cold-Blooded Torture isn't enough to keep her from being sympathetic; her backstory is just that crappy.
  • Tears of Remorse: In the final volume, she can finally apologize to Kouta for killing his father and sister. Her tears show her regret is genuine.
  • Theme Music Power-Up: In the manga, Lucy sings the German song "Elfenlied" while taking on an entire army from thousands of kilometers away. Apparently, the more thematic the song, the bigger the powerup.
  • Then Let Me Be Evil: She's a member of a race genetically predisposed towards the destruction of the human race. Which was only ever triggered because the humans she met all treated her like shit. Nice going there.
  • Token Evil Teammate: In the main cast (consisting of herself, Kouta, Nana, Yuka, and Mayu), she's easily the most unhinged and villainous of the bunch.
  • Tortured Monster: Yes, she's a bitter, mass murdering bulldozer, but she went through some serious tragedy in her life that she'd done nothing to deserve.
  • Tragic Bigot: Lucy strongly believes Humans Are the Real Monsters, and considering all she'd been through because of humans' cruelty, one can't honestly blame her.
  • Tragic Villain: A very tragic one at that. A broken little girl who became a murderous monster after she snapped at the world's relentless cruelty and her own budding insanity.
  • Tranquil Fury: In the anime, where she kills without a change in her facial expressions.
  • Transhuman Treachery: Is a Diclonius, gets treated horrible because of that, and becomes a homicidal maniac and hates humans as a result.
  • Tsurime Eyes: Her eyes are narrow, tortured and focused, in contrast to Nyu's bright and happy Tareme Eyes.
  • Uncertain Doom: In the anime, Lucy most likely survived the officers shooting at her but she loses one of her horns in the process.
  • Undying Loyalty: If her Fatal Flaw is that she Desperately Craves Affection, then her greatest quality is her insane devotion to the people she loves. In fact, her loyalty is arguably greater than her desire for affection, because she willingly puts herself in harm's way for the people she cares about, frequently sacrifices her own betterment in exchange for theirs and absolutely refuses to abandon them or hate them even if they treat her badly.
  • The Unfettered:
    • She will find Kouta, and she will express how awful she feels about killing his family. No way you'll ever stop her from doing that. No way she'll let you stop her from that single goal.
  • Ungrateful Bitch:
    • It is implied she once tried to kill Mayu right after Mayu saved her from being killed, but it isn't clear whether she truly intended to kill her or if it was just a fakeout. Granted, Lucy did have her vectors close to Mayu after she dealt with Bando (who tried to save Mayu as a result), so one could argue this was at least partially attributed to her being a Combat Pragmatist.
    • She also dislikes Yuka, who she hoped to kill in the past after taking her jealous rage out on Kouta's family, an act she abandoned only after a traumatized Kouta begged her to stop. In the present Yuka gives Nyu constant care and affection in spite of her jealousy of Nyu, but this doesn't stop Lucy from slapping her down with her vectors when she sees her and Kouta hold hands, and this was when they were searching for her after she vanished from Professor Kakazawa's lab. However upon seeing how much Yuka means to Kouta, Lucy never tries to harm her again.
  • Unstoppable Rage: About ninety percent of the time. Even trained assassins, other diclonii, and an army of soldiers can't so much as lay a hand on her when she wants them dead and she's pissed off.
  • Used to Be a Sweet Kid: She started out as a kind-hearted, but shy little girl, but through enough torment, crippling loneliness, and a psychotic inner voice, became an Ax-Crazy mass murderer bent on killing all humans.
  • Villain Protagonist: She has killed armed men and innocent children, for reasons ranging from "trying to kill me" to "You killed my dog" to "I envy your happy, normal life, and I need a place to crash" to "It Amused Me" to "I'm going to destroy the world because I'm about to die."
  • Violently Protective Girlfriend: If she sees you as a threat to Kouta, you will die. Period.
  • Vomit Discretion Shot: During her breakdown at the summer festival we hear her vomit with the back to the audience (Strangely, tons of severed heads and oceans of spilt blood are not as bad as a small pool of vomit).
  • Weak, but Skilled:
    • She's actually not that powerful compared to some of the other diclonii; Nana has longer vectors and can hold her at bay, while Mariko is an outright nuke. Lucy is a far more experienced killer, and when Nana tries to go easy on her, Lucy rips her limbs off.
    • Subverted in the end of the manga where her vectors can split islands and have a reach of at least hundreds of kilometers.
  • Woobie, Destroyer of Worlds: Several characters think that it's her natural instinct to eradicate humanity, but given her past, her experiences alone would be enough to make her what she is. She truly believes that she's doing all those atrocities out of instinct, so if we look at the nurture aspect, we come to the conclusion that she Mind Raped herself (with a little help from nearly everyone around her and an inner voice/alternate personality that wants to eradicate all life) into believing that she was, in her own words, "born to wipe out mankind".
  • Would Hurt a Child: Would kill them, actually.
  • Your Head A-Splode: She goes for this when she wants to make a quick kill. But she has other ways of torturing you if she really wants to make you suffer.

Not a separate character in the strictly technical sense, Nyu is the split personality of Lucy that developed after a .50 BMG round grazed the metallic helmet protecting her head. Nyu has a childlike personality, an infantile knowledge of the world, and lacks spoken language skills, only able to say "Nyu" and "Kouta" most of the time. Nyu is innocent and incapable of violent acts, a foil to the normally cold and sadistic Lucy; she is the manifestation of Lucy's "good side".

When Nyu is attacked violently, she regresses into Lucy; likewise, when Lucy is treated with love and kindness or wants to hide herself from Kouta, she will switch back into Nyu. While Nyu exists first due to trauma, it is believed that Lucy subconsciously encourages her presence due to her feelings of guilt towards Kouta.

  • All-Loving Heroine: Nyuu doesn't seem to hate anyone, and loves all around her.
  • Alternate Identity Amnesia: She has no memories of her past or what her Lucy side does.
  • Ambiguously Bi: She loves Kouta, but that doesn't keep her from groping other girls. Even after she becomes intelligent, she wonders why she wants to Skinship Grope Yuka, likely due to her former self's influence.
  • Amnesiacs are Innocent: Because she can't remember all the awful things that happened to her, Nyu is sweet and trusts others.
  • The Atoner: In the anime, as she starts seeing more of Lucy's memories, she feels great regret for her other self's actions. In one scene, she impersonates Kouta's sister Kanae so she can forgive him for the things he said before she was murdered, apologizing profusely for said murder before she reverts back to her usual state.
  • Beware the Nice Ones: Let's just say that putting her in danger, hitting her on the head hard enough, or getting her drunk or drugged will make her revert to her Lucy persona.
  • Big Bad Friend: To Nana, in a sense - Nana hates Lucy, but is good friends with Nyu, even though they are two different personas of the same person.
  • Blank Slate: She has no useful speech abilities, latches emotionally on to the first people she meets, and frequently doesn't seem to understand what's going on. The anime cuts off before Lucy is reduced to an extended coma and Nyu is allowed to develop. She is even able to talk in full sentences, and is, at that point, a full personality that directly contrasts Lucy perfectly. She still keeps her Verbal Tic, though.
  • Bungled Suicide: She tries to cut her wrist when she learns of her Lucy personality and gets terrified that her other self has been killing people.
  • Buxom Is Better: Nyu likes groping bigger breasts and is disappointed of Mayu's small ones.
  • Covert Pervert: She prefers groping bigger boobs than small ones like Mayu's. She also does not grope Kouta because she explains that men have no boobs. Though, she prefers that he would grope her.
  • Double Standard: Rape, Female on Female: She is constantly molesting the other girls that live at the inn. She isn't portrayed as a disgusting creep because she doesn't understand the gravity of her actions, and is only (for the most part) copying things that she's seen others doing.
  • Driven to Suicide: In the manga, when she finds out that she's a mass murderer, she tries to kill herself, but cannot do it.
  • Dumbass No More: In the manga, Nyu develops average intelligence and speech after the six-month Time Skip. She gets embarrassed when her friends talk about how she behaved like a toddler before.
  • Forced Kiss: She steals a kiss from Yuka and Nozomi.
  • Genki Girl: Much more prominent in the manga. After being able to form sentences, she has such a happy personality that the manga looks like a Reconstruction of an Unwanted Harem anime.
  • Helpless Good Side: Lucy is a psychotic murderer. Her other personality Nyu is an innocent amnesiac girl who initially doesn't even know how to use a restroom. She's not so helpless when she's able to use her vectors herself.
  • I Am a Monster: In the manga, when she finds out she's actually a dangerous Serial Killer, she reacts to the truth about as well as you'd expect, and nearly kills herself for it.
  • Innocent Fanservice Girl: She's frequently seen naked or in partial dress, usually due to her childlike personality. That said, she has no concept of privacy or modesty, and it takes some effort before she figures out how to dress herself properly.
  • Innocently Insensitive: She cheerfully breaks the seashell Kanae gave to Kouta, which greatly infuriates him. Yuka tries to defend Nyu, saying that maybe she broke the seashell because she thought it made Kouta sad.
  • Instant Expert: When Nozomi teaches Nyu how to sing, she chooses her favorite song Elfenlied, a German song in old German. Nyu is able to sing it fine and has no trouble with the language at all.
  • Mysterious Waif: Unlike most examples, we more-or-less know from the beginning how she ended up on a beach.
  • Nice Girl: One of the biggest contrasts to her alter ego is her kindness and friendliness.
  • No Sense of Personal Space: She constantly glomps Kouta, and fondles Yuka's breasts on more than one occasion. Not to menton Nozomi's crotch.
  • One-Word Vocabulary: She initially has a very limited vocabulary with "Nyu" being the only word she can say. She slowly learns to say more words. After the 6-month Time Skip in the manga, Nyu can speak full sentences.
  • OOC Is Serious Business: Whenever Nyuu speaks in coherent sentences, it usually indicates something far more serious is going on.
  • Potty Failure: When Kouta and Yuka first bring her to their house, Nyu wets herself because her toddler mentality prevents her from knowing how to use the bathroom.
  • The Prankster: In the manga, she tries to play a prank on Kouta as revenge for scolding at her (and maybe for stopping her Attempted Rape on Nozomi) by surprising him. The timing of her prank is really bad, as the person she surprise turns out not to be Kouta, but Nana, who attacks her because of Lucy dismembering her.
  • Rose-Haired Sweetie: She's innocent, cheery and optimistic in contrast to Evil Redhead Lucy.
  • Skinship Grope: She enjoys groping the breasts of the other women at the inn. She recognizes this behavior as unacceptable due to Kouta's mishap.
  • Suddenly Bilingual: Nyu has no trouble to sing the German song "Elfenlied" for the first time.
  • Tareme Eyes: A contrast to Lucy's Tsurime Eyes, Nyu's eyes are bigger and rounder to make them look cuter.
  • Verbal Tic Name: When Kouta and Yuka find her, she can only say "Nyu" due to the brain damage caused by a bullet to the head. Kouta then names her after the only word she can speak at first.
  • Womanchild: Nyu is essentially an infant in an adult body. Averted later on in the manga.


Kaede is the original personality of Lucy and Nyu. She was once a gentle soul who never knew her parents but had some hopes for the world. That changed when some kids at her orphanage decided to bully her...

  • Blessed with Suck: She was born with powers well beyond anything a normal human can counter, manifested in her distinctive horns. She clearly despises them for all the abuse and mockery thrown in her direction because of her appearance, and her innate hatred for humans has made her cold and distant to most, which only earned her more unwanted attention. That's to say nothing of the absolute hell she endures after killing her best friend's family.....
  • Bloodbath Villain Origin: After she snaps and commits her first murder, the room she's in is almost totally covered with the blood of her victims.
  • Bully Magnet: She was relentlessly bullied by the other children at the orphanage due to her emotionless demeanor and her horns.
  • Clingy Jealous Girl: In the most frightening way imaginable. Her jealousy involves murdering Kouta's family because he went to the festival with Yuka instead of her. She spared Yuka's life only because Kouta would hate her if she killed her.
  • Disproportionate Retribution: She killed Kouta's little sister Kanae and his father in cold blood because he lied to her about the gender of his cousin Yuka. She was eventually aware of this.
  • The Dog Bites Back: She snaps and slaughters her bullies after they take the puppy she'd been caring for and beat it to death right in front of her.
  • Enfant Terrible: She began her killing spree at a young age.
  • Forced to Watch: Her Start of Darkness was when a group of bullies beat the puppy she had started caring for to death while making her watch. They don't survive the consequences.
  • Freakiness Shame: She hated her horns since she was bullied because of them. Kouta was the only kid who thought her horns are cool.
  • Freudian Excuse: Lucy's Kill All Humans mentality began because of the loss of Kaede's puppy at the hands of some very cruel kids, got worse when she felt betrayed by Kouta later on, and practically crossed the Despair Event Horizon after finding out that the human she tried to spare when she turned herself in dies from her wounds.
  • Good Girl Gone Bad: She was a good girl, until a group of orphans beat her puppy to death, the only being in the world she actually cared about. They found out about it from a girl who pretended to be her friend, the first human she was beginning to trust. That's when her murder spree began, although it was put down eventually thanks to Kouta. However, after he lies about his cousin's gender and she finds out the truth, she's gone for good.
  • Hide Your Otherness: Kouta gave her a watch cap to hide her horns because she told him she hated them.
  • Kick the Dog: Many times.
    • When she goes on her rampage in the festival, she kills a woman because she showed concern for her. In this case, however, it's slightly justified in that Kaede was... not exactly in her right mind at the time.
    • Brutally murdering Kouta's father and little sister without any provocation was so horrible and over the top that that even Kaede herself agreed that there was no atonement for that.
  • Kick the Son of a Bitch: The cruel kids at the orphanage, along with Bando (the first time around), the Unknown Man, and Kakuzawa (Junior and Senior), all had it coming.
  • Lost Pet Grievance: She got emotionally attached to a little puppy. Said puppy was practically her Only Friend due to how all the other kids bullied her because of her horns. When the other kids find out about the puppy, they beat it to death and forced her to watch, causing Lucy to reach her Rage-Breaking Point and slaughter all of the kids in the orphanage.
  • Meaningful Name: Kaede refers to a kind of Japanese maple tree, and the Latin Acer is the name for the genus of maples to which it belongs. Acer means "sharp" or "piercing," referring to the bladelike leaves of the maple tree. Fitting given Lucy's personality and her...well, tendency to slice things up.
  • Murder the Hypotenuse: A subverted example. Though she plots to murder her love rival Yuka, Kouta tearfully begs her not to kill more of his loved ones.
  • My God, What Have I Done?: Her murders of Kouta's father and little sister. They're the only kills she actually feels any remorse over.
  • Orphan's Ordeal: She grew up in an Orphanage of Fear where the kids treated her like freak because she isn't human.
  • Start of Darkness: Episodes 8 & 9 show Lucy's backstory as Kaede, along with the only happy day she spent while with Kouta when they were kids. The manga does this sooner, at the time of episode 6.
  • The Stoic: She shut off her emotions in order to deny her tormentors the joy of seeing her in pain, which then became another reason why she was despised, reinforcing the original bigotry and egging to make her react.
  • Traumatic Superpower Awakening: Her vectors first activated after the bullies at the orphanage killed her puppy and made her watch.
  • Tsundere: She pretended she didn't care about Kouta and didn't want to be friends with him or anything, but she still felt happy and blushed when he came to play with her.
  • Walking Spoiler: Her existence revolves around Lucy/Nyu's backstory.
  • Woman Scorned: She killed Kouta's father and sister right in front of him because he took another girl to the festival. She would have killed Yuka too if Kouta haven't begged her to stop.
  • Yandere: She killed Kouta's father and sister because she was angry at Kouta for going to a festival with Yuka instead of her. Disproportionate Retribution at the worst, although she seriously regretted it later, to the point that the thought of eventually apologizing to him gave her the will to survive.

Diclonius DNA Voice
”You should know by now, that it is my destiny to take human life.”
A fourth, hidden personality within the protagonist, she is the one who drives Lucy to murder. She is the reason that Diclonii are driven to kill humans, and she has the ultimate goal of replacing humanity with her species.
  • Apocalypse Maiden: Towards the end of the manga, she finally takes over and starts killing humans everywhere on the world at rates that would make the deadliest WMDs look like mere fireworks in an attempt to destroy humanity in a spiteful decision that since Diclonii, and mainly her, can't rule the world, she'll destroy it.
  • Big Bad: At the end of the series, she takes over as the main antagonist after decapitating Kakuzawa.
  • Big Bad Duumvirate: The voice teams up with Kakuzawa to destroy all humanity.
  • The Corrupter: To Lucy and possibly the other Diclonii.
  • Cute Is Evil: More so than any other character.
  • Enemy Within: Lucy has a pretty complicated mindset. Ultimately, however, it is the voice, the embodiment of her basic instincts, that is the undisputed, unambiguous villain who pushes her to do everything horrific onscreen.
  • Final Boss: After killing Kakuzawa, she becomes the main threat to Kouta and his friends.
  • The Heartless: She's the result of all the abuse Kaede suffered.
  • Hive Queen: Implied to be influencing all the diclonii, not just Lucy.
  • Manipulative Bitch: Plays on Lucy’s insecurities and fears to get her to kill.
  • More Than Mind Control: Inflicts this on Lucy and possibly the other Diclonii by influencing them to kill humans.
  • Non-Action Big Bad: She’s the one trying to destroy humanity, but as pointed out, she cannot directly posses a body- hence she has to rely on Lucy and the other Diclonii to do the killing. Subverted in the finale when she finally does seize control of Lucy.
  • Satanic Archetype: Even more so than Lucy, as she has everything Lucy does and is the one corrupting her.
  • Split Personality: The hidden fourth one, who manages to be worse than Lucy.
  • Suicidal Cosmic Temper Tantrum: Towards the end of the manga, she takes over after realizing that she and the Diclonii can't rule the world so she will kill as many humans as she can before she finally expires.
  • Superpowered Evil Side: Even more so than Lucy.
  • Taking You with Me: She decides to do this to the entire world once she can’t rule it.
  • The Unfettered: She has no reservations about doing anything in her considerable amount of power to kill all the humans and replace them with her species.
  • Walking Spoiler: Her mere existence is a major reveal.
  • Woman Behind the Woman: To Lucy; she’s the one telling her to kill people.

An 18-year-old student who arrives in the Kanagawa Prefecture to attend college. He is the male lead and Deuteragonist of the series. Kouta lives in a closed-down inn with his cousin, Yuka, while attending university.

Kouta has repressed traumatic memories of witnessing, firsthand, the deaths of his father and sister. He ended up in a psychiatric ward for over a year following the event, but eventually made a full recovery. As a result, he is particularly sympathetic towards girls in trouble and is extremely generous to and protective of the girls around him. He is very kind and gentle as well, offering to shelter the various suffering characters he and Yuka stumble across, and treating them as part of his family. He and Yuka both initially meet Lucy as she washes up on the shore of a nearby beach.

  • Accidental Pervert: Yuka slaps him a lot for this. The first time it happened, Nyu had been out in the rain and her clothes were soaked. Kouta tried helping her change with his eyes closed, but his cousin walked in at just the right moment for his honest explanation to be hardest to believe.
  • Adoptive Peer Parent: He and Yuka both adopt Mayu despite the fact that they're both university students and Mayu is 14.
  • Angst Coma: In the backstory, he spent an entire year in a coma after watching his little sister Kanae and his father get slaughtered right in front of him by Lucy.
  • Animal Lover: Kouta loves animals and he studies biology to work with animals.
  • Babies Ever After: The Distant Finale shows him going to the place where he first met Lucy/Kaede to wait for her with his daughter Nyu, who resembles Yuka.
  • Badass Normal: He's not a fighter by any means, but he'll never hesitate to defend his loved ones or those in dire need of help, no matter how outmatched he is.
  • Chick Magnet: He attracts a teenaged, mutant girl with horns on her head and his own cousin! Also Nozomi, but she does not fall for him that hard like the others.
  • Childhood Friend Romance: He was friends with Lucy/Nyu for a short time in their childhood until she killed his father and little sister for taking another girl to the festival. The trauma caused Kouta to erase her from his memories. His current feelings for her are complicated even though he does feel attracted to her.
  • Classical Anti-Hero: Kouta is a protagonist with no superpowers, has some psychological issues and not any talents. He's also a student in a rather low-leveled university.
  • Dark and Troubled Past: He watched the girl he befriended go into a Yandere rampage that killed his father and little sister. He was so traumatized that he changed his own memories.
  • Death Glare: To Lucy, right after he regains his memories in the manga.
  • Deuteragonist: He's the second most important character over here, due to his relationship with Lucy.
  • The Dulcinea Effect: Only slightly, but Kouta is undeniably more inclined to go the extra distance to help out a girl in need.
  • Easily Forgiven: In the anime, he forgives Lucy for killing his family. In the manga? Not at all.
  • First Friend: To Lucy, or rather, Kaede. Before meeting him, Lucy's only true friend was a puppy she secretly took care of at the orphanage. After a girl who stood up for her betrayed her secret and got the pup killed by Lucy's bullies, Kouta would become the first human to truly reach out to her, making him Lucy's Morality Pet.
  • First Kiss: Stolen by Yuka.
  • Forgotten First Meeting: In actuality, Kouta met Lucy in his childhood after she killed her first victims. Unlike everyone else, he found her horns fascinating and forged a strong bond of friendship with her. However, he erased her from his memory after she brutally killed his father and sister right in front of him because he lied to her about his cousin's gender.
  • Freaky Is Cool: He was the first person to think that Lucy's horns are cool.
  • Hospital Epilogue: Even after being healed by Lucy's vectors around the end of the manga, he still had to be admitted to the hospital.
  • Interspecies Romance: With Lucy, since she's a Diclonius.
  • I Will Wait for You: At the end of the manga, he goes to the place where he first met Kaede and waits for her every year on the last day of the summer festival, even though he knows she won't come because he killed her with his own hands. Although, the twin reincarnations of Lucy and Nyu eventually come to meet him.
  • Kissing Cousins: He is attracted to his cousin Yuka, as the temple scene indicates, but then there's Lucy/Nyu muddying things up. In the final chapter of the manga, it's implied they end up together. If Kouta's daughter's resemblance to Yuka is any indication. The manga also implies that his feelings for Yuka were always stronger than for Lucy/Nyu, judging from his many scenes with Yuka.
  • Living Emotional Crutch: To Lucy. His very existence is the only reason Lucy hasn't completely snapped after all the torture humans put her through. She still loves him and one of, if not the only thing that gives her the will to go on is the thought of one day finding Kouta again and apologizing to him for killing his father and little sister.
  • Loves My Alter Ego: He tells Lucy he loves both her and Nyu.
  • Maybe Ever After: He promises Yuka to never leave her again at the end of the manga. In the Distant Finale, his daughter resembles Yuka.
  • Morality Chain: If Lucy haven't met him, she would have given in to her Diclonius impulses and decided to kill all the human race long ago.
  • Morality Pet: To Lucy; he's the only reason she ascended to anti-hero after her start of darkness.
  • Nice Guy: Though not always, but case in point: he was the first human to ever treat Lucy with an ounce of human decency.
  • Nice Job Breaking It, Hero: Lying about the gender of the cousin he was going to the festival with leads to Lucy slaughtering his sister and father in a fit of jealousy.
  • No Good Deed Goes Unpunished: When they meet as children, he is genuinely kind to Lucy. Then, she kills his sister and father.
  • Non-Action Guy: Kouta isn't very strong, smart, has no powers, weapons or anything except some cool friends. Although he has a knack for solving his problems by slapping/punching people in the face.
  • Not What It Looks Like:
    • Played straight when Kouta tries to change Nyu's wet clothes, as she doesn't know how to do it herself.
    • Subverted once when it's exactly what it looks like. Kouta is most definitely groping Nyu, mostly because she made him. Yuka is not exactly convinced by his explanation.
    • Happens again when Mayu sees him and Nyu in the bathtube.
  • Only Friend: To Lucy. She even admits that the times they spent together are the only happy memories she has.
  • Ordinary High-School Student: Kouta is just a normal university student with no speciality.
  • Parental Hypocrisy: He tells his daughter Nyu to not play in the mountains, despite the fact he used to play in the same mountains with Lucy/Kaede when they were little.
  • Parting Words Regret: His last words to his little sister Kanae were a threat that he'd "hate her forever" unless she apologized to his friend Lucy, who Kanae had just accused of murdering people at the festival they were at. Kanae is then bifurcated in front of him... by Lucy herself. He shows clear regret in present times for fighting with her just before she died.
  • Please Put Some Clothes On: When an angry Kouta finds Lucy on the beach near the end, he tosses her his coat.
  • The Promise: Lucy and Kouta agree to meet at the stone behind the festival terrain on the last day of the summer festival.
  • Repressed Memories: Kouta eventually finds out that his father and sister did not die from an accident and an illness, respectively. Instead, they were both murdered in front of him by Lucy, and the trauma of witnessing this caused him to block the memories out.
  • Secret-Keeper: He accidentally discovers Nozomi's embarrassing secret when he catches her checking her dirty diaper. He then throws her into water so the other girls at Maple House don't see her peeing herself.
  • Spell My Name with an "S": Kouta, Kohta or Kota?
  • Star-Crossed Lovers: The murder of his family at her hands really puts a huge problem for his relationship with Lucy.
  • Sympathy for the Devil: Though he can't condone or forgive Lucy's actions by his own admission, Kouta just can't bring himself to hate her.
  • Team Dad: He's sometimes referred to as the "Father" of the group, and he acts like it. Despite looking like a typical Nice Guy, he can be surprisingly strict and gruff when he needs to be.
  • This Is Unforgivable!: He does not forgive Lucy for killing his family, but he's still conflicted with his feelings for her.
  • Tragic Keepsake: The seashell Kanae gave to him on the day of her death.
  • Trauma-Induced Amnesia: A significant part of the plot, as it's about Lucy killing his father and sister in front of his eyes.
  • Unlucky Everydude: Very unlucky. He is constantly found in compromising positions with female characters by... other female characters, and is given a lot of flack for this by Yuka. Not to mention his entire family ends up being killed because of one white lie.
  • Unreliable Narrator: We rapidly learn that Kouta's trauma has rendered him this, when relating how his father and younger sister died.
  • Would Hit a Girl: Not necessarily brutal, but he has no problems slapping women when they upset him. Not to mention that he hits Nyu with a slipper because she was going to, er, have her way with Nozomi.

Kouta's cousin, who is around 19 years old and planning to attend the same university as Kouta. She moves in with him at the inn after having not seen him in many years. Having had a crush on Kouta since childhood, she still harbors strong feelings for him, and is openly jealous of Kouta's attention to Nyu, to the point of being irrational.

Despite her brash tendencies, Yuka is genuinely as kind and caring as Kouta. Though she is hesitant and reserved, she is accepting of Kouta's decision to use their inn to shelter those in need.

  • Adoptive Peer Parent: She and Kouta become the legal guardians of the abused Mayu. Yuka is 19 and Mayu is 14, so she's only five years older than her adopted daughter.
  • Armor-Piercing Slap: Yuka gives such a hard one to Kouta early in the anime that in the next scene you can still see her hand imprint on his cheek.
  • Betty and Veronica: Betty to Lucy/Nyu's Veronica, since Yuka is a normal, sane girl and not a psychotic murderer. It's obvious which of the two is the one Kouta feels more at ease with.
  • Clingy Jealous Girl: She gets easily jealous whenever she catches Kouta and Nyu having a "moment", especially in the anime.
  • Cool Big Sis: She's a caring older sister figure to all the younger girls living with her.
  • Cross-Popping Veins: Happens to Yuka twice, once when Kouta was about to mention that her cooking wasn't special, and when his little sister teases her in the flashback.
  • Cry Cute: She tearfully admits to Mayu that she loves Kouta and is greatly jealous of Nyu because of the attention she receives from him.
  • Double Standard: Abuse, Female on Male: Yuka tends to get pretty violent on Kouta several times.
  • First Kiss: With Kouta. In the manga, it's a French kiss.
  • Kissing Cousins: She is infatuated with her cousin Kouta. Kouta is also attracted to her, as the temple scene indicates, but then there's Lucy/Nyu muddying things up. The ending of the manga implies Yuka does eventually marry Kouta and has a daughter with him.
  • Impossibly Tacky Clothes: Some of her outfits that she lends to Nyu tend to really stand out, to say the least. They certainly suit the plucky and childlike Nyu just fine, but they contrast drastically with Lucy's vengeful and apathetic persona.
  • Innocently Insensitive: She gets mad at Kouta for not being able to remember a promise due to his sister and father getting violently murdered in front of him about twenty minutes after making said promise in some rather guilt-inducing circumstances. Granted, she has no idea that he repressed his memories of that day, and she regrets her earlier reaction once she figures this out.
  • Jerkass Realization: After reflecting on why Kouta felt the need to take in Nyu and the other girls who were left with nowhere else to go, Yuka saw herself as a terrible person for how much she scorned Kouta through all they've been through, realizing that she was being selfish in her feelings.
  • Jizzed in My Pants: To her embarrassment, she wets her panties whenever she has an arousing moment with Kouta or Nyu.
  • Let's See YOU Do Better!: During the festival flashback, Yuka is constantly breaking the clay animals at one of the stands. Kouta says that she's terrible at it, so Yuka tells him to do it if he's so awesome at it. Then he does and manages to get the animal shape out of it, and she promises to get better at it.
  • Love Confession: When Yuka confesses to Mayu how jealous she gets whenever Kouta pays attention to other girls, Mayu gently asks Yuka if maybe the reason she gets so jealous is that she loves Kouta. Yuka tearfully admits she's right.
  • Maybe Ever After: Kouta promises Yuka to never leave her again at the end of the manga. In the Distant Finale, Kouta's daughter resembles Yuka.
  • Misery Poker: She spends so much time fuming over the fact that she can't get close to Kouta when everyone else has been to hell and back.
  • Ms. Fanservice: See Reluctant Fanservice Girl below.
  • Only Sane Woman: She is the only main character without any serious traumatic event in her backstory. The fact that she is a typical Tsundere in a world where every main character has serious mental disorders makes her the most normal of all them.
  • Please, Don't Leave Me: In her final scene in the manga, she tearfully asks Kouta to never go anywhere without her again.
  • Reluctant Fanservice Girl: Takes up the Ms. Fanservice role rather unwillingly, due to her being a frequent victim of Nyu's antics or getting Panty Shots that are seen by Kouta.
  • Strong Family Resemblance: Her daughter, Nyu Jr., looks exactly like Yuka.
  • Team Mom: As the oldest of the girls, she is sometimes referred as the "mother" of the group in the anime.
  • Tsundere: Sweet type. She's usually a sweet girl, but she can be violent and harsh towards Kouta.
  • Vitriolic Best Buds: With Nyuu; she gets along civilly with her but admits she is jealous of the affection Nyuu constantly receives from Kouta, feeling she has been cast aside by her own cousin. Nyuu meanwhile loves her company and constantly feels the need to grope Yuka, much to her dismay. However, Lucy holds very clear contempt towards Yuka in spite of the care she receives from her and would've killed Yuka years ago if not for the guilt she felt over Kouta's sister and father. Luckily, this guilt means Lucy cannot bring herself to kill another one of Kouta's friends or family, and after the one time she pushed her with her vectors she quietly resolves not to harm Yuka again. In the manga, she trusts Yuka to care for everyone at the Maple House.

A 14-year-old girl, neglected by her mother and a victim of sexual abuse by her stepfather. She eventually runs away and is homeless at the start of the series, living on the beach and subsisting on bread crusts from a local bakery under the pretense that they are for the small puppy, Wanta, that accompanies her. She ends up living with Kouta and Yuka as her legal guardians, and later befriends Nana and tries to take her under her wing.

  • Attempted Rape: She was very nearly raped by the Unknown Man in the manga.
  • Broken Bird: She was badly traumatized by her stepfather's sexual abuse and her mother's indifference.
  • The Conscience: She tries to talk Nana down from killing Lucy and keep the peace between them.

  • Does Not Like Men: Her traumatic experience with her stepfather has soured her on men in general, and finding Kouta in the bath groping Nyu doesn't help. Bando is the only man she's never afraid of.
  • Faint in Shock: She passes out from the shock of seeing Nana's prosthetic leg fall off.
  • Happily Adopted: By Kouta and Yuka. They later track down Mayu's mother, who signs over legal guardianship to them without any complaint (she didn't want Mayu in her life anyway).

  • Intergenerational Friendship: She bonds most closely with Bando who is at least ten years older than her.
  • Interrupted Suicide: Heavily implied in the anime, after running away from home. She leaves her shoes on the shoreline and starts to wade out into the ocean, but turns back when she hears a puppy barking. Supplementary materials confirm that Mayu cannot swim.
  • Interspecies Friendship: With Nana. Mayu is careful to protect Nana and her true nature as a Diclonius.
  • Let Them Die Happy: When Bando lies dying after Taking the Bullet from Lucy for Mayu, he asks what happened to Lucy. Before Nana can tell Bando she got away, Mayu says that Bando's last bullet killed her, so he can die believing he finally got his revenge on Lucy. Subverted when Bando turns out to be alive in the last chapter.
  • Little Miss Snarker: In the manga, she shows some moments of genuine wit and sass, sometimes making sarcastic remarks in response to Kouta's Accidental Pervert antics.
  • Morality Pet:
    • Her relationship with Bando is one of his most humanizing traits. He generally treats her like crap just as he does with everyone else, but she's the only person he goes out of his way to protect.
    • In the anime, when Lucy is fighting Nana at Maple House, Mayu tries to give her a Cooldown Hug, and Lucy immediately stops using her vectors to avoid hurting her.
  • Nice Girl: Mayu is very friendly considering her Dark and Troubled Past. She does her best to see the good in everyone, Lucy and Bando included.
  • Parental Neglect: Mayu's mother didn't care about her new husband sexually abusing her daughter. Later, she willingly gives up custody of Mayu to have her stay with Kouta and Yuka at the Maple House.
  • Plucky Girl: Mayu's got bravery to spare when she's pushed to it, as she shows when Bando tries to threaten her into revealing Nyu's location and she has the presence of mind to call him out to his face.
  • Precocious Crush: She develops feelings for Bando who is old enough to be her father. She confesses her feelings by kissing him after he's torn in half by Lucy.
  • Rape as Backstory: She was sexually abused by her stepfather.
  • Rape as Drama: Mayu is an unfortunate victim of Rape as Backstory and Attempted Rape.
  • The Runaway: After enduring sexual abuse at the hands of her stepfather, Mayu decided enough is enough and ran away from home. She then lived at the beach until she was taken in by Kouta and Yuka who let her move into Maple House with them.
  • Sailor Fuku: She wears this as a school uniform after moving in permanently with Kouta and Yuka.
  • Shrinking Violet: Due to being homeless and having a traumatic backstory, Mayu is withdrawn and timid in the beginning.
  • Tears of Joy: Tears from her eyes when Kouta and Yuka welcome her to live with them, letting her know she isn't a burden to them.
  • Trauma Button: Mayu was sexually abused by her stepfather on a regular basis, leading to her running away. When the Unknown Man attacks Maple House and tries to rape her, Mayu flashes back to her stepfather doing so and flips out.
  • Trauma-Induced Amnesia: Mayu does this to a lesser extent regarding her witnessing Lucy's brutal dismemberment of Nana.


A puppy that Mayu found when she was helpless. He is a lost dog belonging to a woman who named him "James", but he runs away from her to stay with Mayu and lives together with the Maple House citizens.

  • Balloon Belly: He gets one after being overfed by Nana.
  • Canine Companion: Mayu rarely goes anywhere without Wanta.
  • Heroic Dog: Both supported and subverted in Mayu's dog Wanta. His loyalty to Mayu (even over a woman who claimed to be his true owner) and the others is stellar. But like his human and otherwise friends, his ability to save them is way limited, and he is nearly killed by the vicious Unknown Man.
  • Precious Puppies: He's a little, adorable white puppy and one of Mayu's best friends.
  • Small Role, Big Impact: He comes into Mayu's company after she runs away from home, and it's his sudden appearance that renews her will to live. Together, they eventually find a new life for themselves in the Maple House.

Also known as Number 7, she is a young Silpelit (Diclonius born from a human) girl who has the physical appearance of being 14 years old. Most Diclonius babies are euthanized at birth, but Nana was one of a handful kept alive for use as a test subject. Nana was a stand-out subject among the Diclonius for being able to effortlessly repress her murderous instincts. Accordingly, she has never used her vectors to harm humans (or anything for that matter). Chief Kurama sees her as his daughter and cares very much for her.

  • Adaptation Dye-Job: Her hair is purplish-blue in the manga, but is purplish-pink in the anime. Also her eyes were green in the manga rather than rose-pink.
  • Adaptational Jerkass: In the manga, when she offers to help Bando up only for her arm to fall off, she's hurt when he accuses her of doing it on purpose. In the anime, she instead laughs and asks, "So you figured it out?", which suggests that she actually did do it on purpose. This is changed in the dub, where she apologizes.
  • Adaptational Wimp: In the anime, she's completely curb-stomped by Mariko. This also happens in the manga, but there Nana fights back and gets even the upper hand. Actually, she wins and might have killed her if Kurama has not appear there.
  • Afraid of Needles: She's scared of injections.
  • An Arm and a Leg: The end result of her fight with Lucy ends with Lucy tearing off all of her arms and legs one by one.
  • Artificial Limbs: She gets realistic prosthetic arms and legs to replace the ones Lucy ripped off.
  • Badass Adorable: Nana is one of the sweetest characters in the series. However when pushed she is more than capable of kicking ass, especially if someone threatens Kurama.
  • Benevolent Monsters: Even though she's a Diclonius and was tortured most of her life, Nana harbors no ill will towards humanity, loves her human adoptive father and lives peacefully with the humans at Maple House. Overall, she's also totally harmless unless someone threatens the people she cares about, especially Kurama.
  • Beware the Nice Ones: The few times said cutie-persona/psychological-defense-mechanism is broken through. During Nana & Bando's first meeting on a moonlit beach, Bando pushes her too far and she snaps on him, gaining the same dead look in her eyes that Lucy almost-constantly has and trying to kill him (and coming very close) until a .50-caliber bullet grazing her head knocks her back to her senses. Later in manga Chapter 74, the Unknown Man threatening Mayu and casually killing Number 28 right in front of Nana is enough to set her off again. Unfortunately, he blasts her before she can attack, taking her out of the fight.
  • Blemished Beauty: Lucy rips off all her limbs and they're replaced with prosthetics. She still looks cute.
  • Blonde, Brunette, Redhead: In the manga, she's the brunette to Mariko's blonde and Lucy's redhead. In the anime, they all have pink hair.
  • Broken Tears: She breaks down in tears when Kurama rejects her for not being Mariko.
  • Can't Catch Up: Despite smarts in battle and ever-increasing savvy, she has a good showing but always gets curbstomped by opponents.
  • Cassandra Truth: Nana knows about Nyu's alternate personality Lucy, but no-one else believes her.
  • Curb-Stomp Battle:
    • Finds herself at the end of these, most noticeably against Mariko. However in the manga she often ends up returning the favor, often to the person who was just beating the living crap out of her as Mariko can attest.
    • She also casually beats the clone of Mariko, Barbara, senseless until the latter takes Kurama hostage.
  • Cute Clumsy Girl: Combine with Artificial Limbs that are quite prone to popping out and, well...
    • It's much rarer in the manga which mostly consists of her limbs falling off when fighting.
  • Cyborg: She gets four prosthetics and they're not as strong as flesh-and-blood limbs, but Nana gets creative with combining their detachable nature and her vectors.
  • Death Faked for You: After she fails to kill Lucy, Director Kakuzawa order Nana to be disposed of. Kurama couldn't stand to let that happen, so he instead puts Nana to sleep and sends her away from the research lab in an escape capsule where he leaves her money that should let her feed off for herself somewhere else.
  • Despair Event Horizon: Between the loss of her limbs at Lucy's hands, Kurama releasing her to fend for herself for the sake of her own survival, and finally witnessing her "father's" suicide, Nana seems to be a frequent victim of this. Justified though as she is the only Diclonius not to be a sadistic killer and like Lucy has lived a hellish life sheltered inside the facility; unlike Lucy though she has never stepped foot into the outside world, and thus struggles to find the peaceful life she desires.
  • Detachment Combat: Prosthetic limbs plus vectors equals projectile appendages!!!
  • Determinator: She's on the receiving end of several Curb Stomp Battles, but still gets up for the next one.
  • Disability Superpower: Lucy rips out Nana's limbs, but Nana later uses her prosthetics as part of her fighting style.
  • Even the Loving Hero Has Hated Ones: Nana is nice to almost everyone and actively defies being a killing machine, unlike most Diclonii. However, she loathes Lucy for being murderous and ripping her limbs off.
  • Evil Wears Black: Averted. She wears black, yet she is the most moral and pure out of all the characters, especially given the morality of the series.
  • Extremely Protective Child: She's usually the most harmless Diclonius, but threaten her papa Kurama and she'll show you she can be fierce too.
  • The Fettered: She's the only Diclonius with strong morals that keep her from becoming a killing machine like other members of her species.
  • Fingore: In the anime, Lucy chops off all of the fingers on her right hand before ripping her right arm off.
  • Good Counterpart: Nana can be seen as the exact opposite of Lucy. While Lucy's default personality is serious and cold, Nana's is fragile, friendly, and kind. Nana's default personality is very similiar to Nyu and she also has an endearingly immature knowledge of the world.
  • Handicapped Badass: Having all of her limbs ripped off and replaced with prosthetics doesn't stop her from taking on Bando and winning.
  • Hellish Pupils: In the manga, whenever she acts like an evil Diclonius. This is true of the anime as well, where she gains these whenever she senses Lucy's presence. In her first meeting with Mayu, she cannot sense Lucy but when told about Nyu she gains these upon realizing they are in fact the same person.
  • Hero Antagonist: To Lucy. While she does work for the Research Containment Facility, she works for Kurama and she's got to be the most straight-up heroic character in the series.
  • Heroic Willpower: Otherwise, she would have become just as homicidal as all the other Diclonii.
  • Imaginary Friend: Cruelly subverted. Nana tries to tell the others that Cute Mute Nyu has a murderous Superpowered Evil Side named Lucy, but they think that it's just this.
  • Incorruptible Pure Pureness: Everything dumped on her only makes her sweeter and more heroic, not less.
  • Interspecies Romance: Implied with Kurama at the end of the manga.
  • Last of Her Kind: She very well could be the last Diclonius following the development of the vaccine.
  • Lethal Chef: Given that she was raised in a lab, this isn't all too surprising (especially in the OVA: first, she burns some in a pan, then she's too enthusiastic cutting the lettuce, her prosthetic arm comes of and the knife nearly hits Mayu).
  • Love Martyr: When she finally sees Kurama again after he's missing for six months, he's too focused on grieving Mariko's death and dismisses Nana as a "mere test subject" who isn't even his real child. Nana feels angry at Kurama's coldness to her even though she had been waiting for him and worrying the entire time he was gone. Despite that, Nana still loves him and chooses to be with him even if he rejects her. Her love eventually helps Kurama recover from his depression.
  • Made of Iron: She takes a bullet to the face from Bando, and all it does is knock her back to her senses and freak her out from the sight of the blood.
  • Money to Burn: A variation; she's so clueless over the concept of money that she uses the yen Kurama left her with for kindling.
  • Morality Pet: Even though he's dedicated to the elimination of the Diclonius species, Chief Kurama truly cares about Nana as his adopted daughter and defies Director Kakuzawa's direct orders to ensure her survival.
  • Ms. Fanservice: There are TONS of scenes of her naked throughout the series.
  • Mundane Luxury: To someone who was raised as a test subject like she was, a simple hot bath is a luxury.
  • My Name Is Inigo Montoya: Nana invokes this one constantly, usually just after she's been dealt a severe injury in combat, with "This doesn't hurt at all!" Also usually, the trope is horrifically subverted. Occasionally the reverse occurs, and Nana goes on to triumph in the encounter (albeit, usually, temporarily).
  • My Species Doth Protest Too Much: Diclonii are genetically driven to murder, right? Not this one.
  • Naked on Arrival: Like any other Diclonii, she's introduced completely naked. Chained to a wall and covered in blood.
  • Nice Girl: She is kind and sweet to just about everyone. She only ever loses her temper when it comes to Lucy, for understandable reasons.
  • No Social Skills: She knows absolutely nothing about the world outside the complex where she used to live, to the point of burning a "bunch of papers" that turned out to be money. And being gullible enough to believe that the money when kept together would attack her in her sleep.
  • No-Holds-Barred Beatdown:
    • Lucy keeps dismembering her limbs even if she's already defeated.
    • Receives a brutal one from Mariko. In the manga however, Mariko makes the mistakes of threatening Kurama. Nana's response is to punch her senseless and disable her vectors before threatening to kill her.
  • No Longer with Us: Nana just felt like being melodramatic for some reason...
  • Only a Flesh Wound: Subverted in her battle with Lucy; after she gets her leg and fingers chopped off, she insists it doesn't hurt... only to drop the tough girl act and scream in agony when Lucy takes off one of her arms.
  • The Pollyanna: Admirably and heroically. Under ridiculously brutal circumstances that turned other Diclonii into killers. Choosing not to be one of the series' unstoppable killing machines, Nana maintains an unshakable positive outlook, anchored by her belief that everything will be OK when she can be with papa again.
  • Power Nullifier: She can use her vectors to temporarily disable other Diclonius's vectors. This is how she disarms Lucy, unfortunately only after losing all her limbs for her troubles.
  • Pro-Human Transhuman: Even though she is a Diclonius, she has maintained her faith and trust in humanity in spite of the extreme odd stacked against ther.
  • Raised in a Lab: She has spent her entire life in the Diclonius research facility where she was raised as a test subject.
  • Redemption Equals Life: If you count simply being a Diclonius as a state in dire need of redemption, Nana definitely qualifies. She is one of the kindest characters in the series, meaning she staunchly rejects the inherent, ingrained desire to eradicate all humans. She never takes a single life throughout both the anime and manga and is amply rewarded by being the only Diclonius to survive the manga.
  • Reluctant Monster: She's the only known Diclonius to be able to effortlessly repress her murderous instincts.
  • Replacement Goldfish: Kurama kinda adopted her to make up for trying to kill and abandoning Diclonius biological daughter Mariko, since Nana isn't anywhere as dangerous as Mariko. Later in the manga, however, Kurama and Nana agree she can't be a replacement to Mariko after Mariko's death. Nana then decides she'll become Kurama's wife in the future so they can be a family.
  • Rocket Punch: Bando lured her on the beach, where she couldn't use anything as a projectile to throw at him. She used her artificial arm. She later uses her arms this way again.
  • Rose-Haired Sweetie: She has pink hair in the anime like all other Diclonii. Unlike other Diclonii, Nana is a sweet and friendly girl.
  • Self-Harm: She once tries to hit her head until she bleeds, in hopes she'll lose her memories and powers like Lucy/Nyu.
  • Self-Proclaimed Love Interest: In the manga, after her father figure Kurama says Mariko is his only daughter, Nana starts calling herself his wife out of wish to become a real family with him. Kurama never says he agrees, but he does assure Nana that he won't leave her again.
  • Seven Is Nana: Nana is Diclonius subject Number Seven.
  • Shameful Strip: Mariko humiliates her by subjecting her to Clothing Damage with her vectors, while disabling her artificial limbs, leaving her a helpless, screaming, crying mess while Mariko simply starts giggling innocently.
  • Slasher Smile: Even she has these kind of smiles, mostly when she fights other Diclonii and has the upper hand.
  • Thou Shalt Not Kill: She's the only Diclonius to have never killed a person, even when she's at her worst.
  • Token Good Teammate: Unlike the Diclonius research institute and the entire Diclonius species, Nana is a peaceful Diclonius who never kills a person in the entire series.
  • Token Heroic Orc: She's the only known Diclonius who isn't a sadistic killer.
  • Took a Level in Badass: After her defeat by Lucy, Nana becomes better in battles. Often because of her Artificial Limbs she can throw as projectiles and other quick surprise attacks. Also, in every battle with Mariko and her clones, Nana gets the upper hand at least once per battle, depending on the occassion.
  • Too Incompetent to Operate a Blanket: She was raised in a lab, and thus, unable to even cut a cabbage with an ordinary knife. When she first meets Mayu, she is completely clueless over the concept of money and uses the yen Kurama left her with for kindling.
  • A Tragedy of Impulsiveness: Kurama explicitly told her not to engage Lucy when he found her, but she chose to do so anyway in an attempt to make him proud. It ends badly.
  • Tranquil Fury: Bando makes the exceedingly foolish mistake of pushing Nana too far the first time they meet, and she lapses into this: he even gets a flashback of Lucy looking at her like this.
  • Upbringing Makes the Hero: Despite her brutal life as a test subject, her adoptive father Kurama treated her with genuine kindness and concern. This is likely the reason why she's the only Diclonius who has a benevolent nature and didn't develop murderous impulses.
  • Vitriolic Best Buds: With Nyuu; she despises Lucy for having ripped off her limbs, a battle that nearly killed her. However, she eventually warms up to Nyuu despite their first meeting, who takes her in to their home with open arms.
  • Younger than She Looks: Silpelits age at about double the rate of normal humans. Nana looks 14 and is really only around seven years old, she also ACTS like her real age too.

A 18 year old girl who's Yuka's best friend and kohai, she aspires to become a famous opera singer.

Due to her father's rather... violent opposition of her dream, Nozomi developed a psychological trauma that makes her wet herself whenever she becomes too nervous. Despite this, she tries to get into a music high school, secretly training at the Maple Inn, which Yuka invited her to, during her free time and moving there permanently after getting accepted.

  • Adapted Out: Despite being a main character, she was written out of the anime.
  • Beautiful Singing Voice: Kouta and Yuka believe she has the skill to become a singer.
  • Book Smart: According to Yuka, Nozomi usually takes first place on the mock exams. Later, it's mentioned she's the third in the country at mock exams.
  • Cute Mute: In chapter 83, her throat gets crushed by a soldier, leaving her unable to speak until the final chapter.
  • A Day in the Limelight: She has a special chapter in the manga depicting her past.
  • Dream-Crushing Handicap: A defied example. She has a throat defect that will eventually make her lose her voice if she strains it too much. Her father desperately tries making her give up on her dream of becoming a singer out of fear that she'll also lose her voice and possibly kill herself like her mother did. Nozomi still decides to not give up and pursues her dream anyway.
  • Hime Cut: She's a borderline Yamato Nadeshiko and so she has a borderline hairstyle associated with them.
  • Jizzed in My Pants: When having a moment with Kouta, she thinks she peed herself again. When she checks, she realizes she didn't wet herself with pee this time...
  • Potty Failure: Played for Drama. Due to her father's abuse, she's developed a bladder control problem that causes her to wet herself whenever she gets too nervous. It actually happens to the extent that she has to wear diapers.
  • Pursuing Parental Perils: Nozomi's mother is an opera singer who lost her voice due to a vocal cord defect, which leads to her being Driven to Suicide. Even though her father warns her about this, Nozomi chooses to still try and become a singer.
  • The Runaway: While she didn't really run away in a direct way like Mayu, she still kind of qualifies as an Abused Runaway.
  • Sacred First Kiss: Her first kiss is stolen by Nyu. It's a Forced Kiss.
  • Shrinking Violet: She's very shy and soft-spoken thanks to her father's abuse.
  • Textile Work Is Feminine: She's confident of her sewing skills.


A baby bird that falls out of its nest, and is found and taken care of by Nyu.

  • Adapted Out: It does not appear in the anime.
  • Irony: While watching Nyu tenderly cradle Piyopiyo in her hands, Nana wonders what would happen if she knew that she had slaughtered dozens of innocent people in unimaginably gruesome ways.
  • Ridiculously Cute Critter: It is a tiny baby bird whose delicate state immediately wins over Nyu's heart.
  • Verbal Tic Name: Piyopiyo is the Japanese onomatopoeia for a bird's chirping.
  • What Happened to the Mouse?: It does not appear again after Chapter 73, so its fate is unknown. The Maple House residents may have continued to take care of it or returned it to its mother in the garden.


Diclonii Research Facility

    Director Kakuzawa 
Voiced by: Kinryu Arimoto (JP), Andy McAvin (EN), Pedro D'Aguillón, Jr. (Latin American Spanish)

The director of the Diclonius research facility. He is a repulsive, power-hungry man lacking any sense of morality and will do whatever it takes to achieve his goals.

  • The Bad Guy Wins: In the anime only, he succeeds in killing Lucy. However, the story ends on a Cliffhanger of epic proportions due to the manga being far from finished at the time. Subverted in the manga where he is killed by Lucy and his plans ultimately fall apart. He does however come damn close.
  • Bald of Evil: He's actually bald and wears a wig because he has horns. He's also the Big Bad.
  • Batman Gambit: Starting immediately after the point where the anime cuts off, Kakuzawa initiates the second part of his plan: a missile launch with the Diclonius virus that would spread into the Japanese population, and, later, the world; in other words, the population of Japan would have their future children Diclonius, without them knowing of it. An attempt to actually stop this from happening does not work, and the gambit proceeds as planned. It would have worked if it wasn't for Arakawa and her knowledge of the Diclonius virus, so it gets foiled later on. The rest of the manga is spent attempting to make sure the scenario does not proceed into even worse territory.
  • Big Bad Ensemble: He works together with the DNA Voice to destroy humanity. Kakuzawa runs the horrific research facility and is Lucy’s greatest enemy, definitely moreso in the manga, at least until the DNA Voice offs him and becomes the main threat at the end of the series.
  • Blasphemous Boast: "Not even God can stop me now!"
  • The Chessmaster: Manga only. Kakuzawa makes numerous plans to achieve his goal, from Diclonius virus missiles, to his goddess daughter Anna to a male Diclonius. Things seem to fall into his very hands and he runs circles around those trying to stop him. If it wasn't for a combination of unforeseen circumstances, most notably Arakawa's vaccine, he would have won even after being killed.
  • Dirty Old Man: He misuses Shirakawa as his sex slave and is a very creepy rapist. And his youngest son, he male Diclonius is born to impregnate his half-sister Lucy. Yes, this man wants a girl in her late teens to be pregnant as soon as possible.
  • Disc-One Final Boss: He may have been killed by Lucy, but all that's left at this point is her DNA Voice.
  • Equivalent Exchange: He believes that Kurama must trade Mariko's life, which is Kurama's daughter for working with him.
    A human has no more than two hands. To take something, one must drop what one's holding.
  • Evil Is Hammy: He really loves to say his plans out loud.
  • Evil Is Petty: Considering he's just a normal person with some genetic abnormalities, his desire to Take Over the World with Diclonius is ultimately either a giant ego trip over a delusion of being something he never was, or simply the spiteful machinations of a man who knew he was nothing special.
  • Evilutionary Biologist: His "diclonius" efforts. Too bad for him that pissing off the crux of his plans (Lucy) slaps him with the Too Dumb to Live label.
  • Final Boss: He is the last enemy that Lucy confronts, though not the last enemy overall.
  • Godhood Seeker: His ultimate goal is to become the god of a Diclonius-ruled world.
  • Hate Sink: He is responsible for all the horror the Diclonii suffer, and the living embodiment of Humans Are the Real Monsters.
  • Hide Your Otherness: He wears a wig to hide the horns in his head.
  • Hoist by His Own Petard: Satisfyingly killed by Lucy in the manga.
  • Horned Humanoid: He has small horns in his head that he sees as proof that he's a Diclonius. However, Lucy reveals he's a human and his horns are just a skull deformity.
  • Human All Along: He believed he was descended from Diclonius ancestry that has been watered down by inter-breeding with humans. However, Lucy doesn't sense any Diclonius genes in him and concludes the horns in his head are a mere deformity.
  • Idiot Ball: His plans involve making it so that all children except Lucy's are born slipelits, which are sterile, thereby reducing the Earth's population to one breeding pair (Lucy and himself) plus his male Diclonius son, which will almost certainly result in extinction of the Diclonii as well even if Lucy cooperates.
  • Large and in Charge: According to the full-cast shot in the last chapter, he is taller than the rest of the cast by a notable amount.
  • Macho Masochism: Doctor Nousou has at one point developed a way to control the violent silpelites via brain chips, and, when prompted by Director Kakuzawa, demonstrates their complete obedience by ordering one of them to stab herself in the arm. Kakuzawa's reaction? He pulls his gun and shoots himself in the hand, remarking disappointedly that pain is no guarantee for obedience.
  • Medical Rape and Impregnate: A very creepy and disturbing example, as he found, captured and impregnated Lucy's mother in order to have a Diclonius male heir that he intended to mate with Lucy, the boy's half-sister. Even when the mother manages to kill herself in captivity, he has her dissected and tries to harvest her reproductive organs and materials. To cap it off, when he tells all this to Lucy, he regards these actions as now making them related. Lucy notably and memorably disagrees with this.
  • Mole in Charge: He half-heartedly puts up a front of wanting to protect the human race from the diclonii, the stated purpose of the research facility he runs, while really wanting the diclonii to wipe out and replace humans.
  • A Nazi by Any Other Name: His beliefs that the Diclonius are Master Race intended to wipe out and replace humanity are eerily similar to the Nazis' beliefs of the Aryan Master Race. It's really telling when the project that will kickstart it all is called "Lebensborn".
  • Non-Action Big Bad: He relies on his henchmen and Diclonii to fight for him. Best shown when Lucy kills him in one shot.
  • Only One Name: In contrast to the other Kakuzawas, his first name is not revealed.
  • Outliving One's Offspring: His son tries to capture Lucy and ends up murdered by her.
  • The Reveal: During his final confrontation with Lucy, it is made known that his family were never true Diclonius, merely Humans with a minor genetic mutation who invented legends and eugenic myths to cope with the persecution they faced in medieval times. The strife he caused our heroes and the world takes on a whole new light.
  • Slasher Smile: Pulls off a few. Despite this most of his expressions are actually quite stoic.
  • Stalker with a Test Tube: A rare male example.
  • The Stoic: More so in the manga. A few hammy speeches and smirks aside, he always remains calm and collect only ever showing the slightest surprise a very few times.
  • Stupid Evil: He taunts Lucy over what he did to her mother, which predictably results in his own defeat.
  • The Unfettered: His goal is to wipe out the human race, replace it with the Diclonius, and be worshiped by them as their new "God".
  • Utopia Justifies the Means: His goal is to destroy the human race and produce more Diclonii using Lucy, the only fertile female Diclonus, to replace them. He doesn't want to do this for any moral reason, though, but only so that in 100 or 200 years he can be worshipped as the god of the new species.
  • Villainous Parental Instinct: Subverted, despite appearing to love his daughter Anna in the manga, it is clear he only sees her as a tool for the advancement of his plans. Although, it's implied he did something that returned her to her original human form after Lucy destroyed her mutated head. Ultimately, Anna is left thinking her father did care about her a little.

    Dr. Kurama 
Voiced by: Osamu Hosoi (JP), Jay Hickman (EN), Gerardo Reyero (Latin American Spanish)

The chief of research of the Diclonius children in the research containment facility.

  • Arch-Enemy: He has the extremely dubious honor of being the human Lucy seems to hate the most - the one who's still alive, at least. He was the one who oversaw her initial capture, but more importantly he didn't keep his promise to save Aiko if Lucy would surrender, putting him on the same short list as Kouta of humans Lucy will not kill, but for very different reasons. Which makes it sort of fitting that towards the end of the manga, Kurama accidentally shoots and nearly kills Kouta right in front of Lucy in a way similar to Aiko's death.
  • An Arm and a Leg: Lucy cuts his arm off. It was self-defense.
  • Badass Bookworm: A scientist who punches Lucy out without fear for what she did to Nana.
  • Beard of Sorrow: After the Time Skip of the manga, Kurama has grown a beard as he has spent months in a state of shock and depression because of Mariko's death.
  • Blatant Lies: Implied. At the end of the manga it's revealed Aiko did survive her bullet wound. It's implied he lied to Lucy that she was dead so she won't pursue her again.
  • Broken Tears: In the manga, he has a tearful breakdown after Mariko dies. And again when one of Mariko's clones dies in his arms.
  • Byronic Hero: Kurama is a stern, no-nonsense man who is devoted to his job, in spite of the horrible atrocities that were being carried out. As the series goes on, he has plenty of sympathetic moments due to his conflicts about what he believes must be done to protect humanity from the Diclonii children and his own morals.
  • Cradle of Loneliness: After one of Mariko's clones dies in his arms, Kurama keeps holding the body for days.
  • Death by Adaptation: He dies in the anime, but he stays alive in the manga.
  • The Dragon: To Director Kakuzawa in the first half of the manga, as well as in the whole anime.
  • Dying Declaration of Love: In the anime, Kurama tells Mariko that he and her mother loved her before the bomb inside Mariko kills them both.
  • Easily Forgiven: He tried to strangle a newborn Mariko to death and when he couldn't do it, he had her locked up in a top-security prison for her entire life. Despite of that, Mariko almost instantly forgives her father to the point she doesn't hesitate to die for him after he hugs her and admits he does love her after all.
  • Excessive Mourning: His immense grief over his biological daughter Mariko's death causes him to neglect his adopted daughter Nana for a while.
  • Final First Hug: He embraces his daughter Mariko for the first and only time shortly before she dies protecting him from Lucy. It's even more depressing in the anime where Kurama hugs Mariko to die with her just as the bomb inside her explodes.
  • Fond Memories That Could Have Been: In the anime, right when the bomb inside Mariko detonates and kills them both, Kurama imagines himself, his wife and Mariko being a happy family as he realized that life could have been possible if he had accepted his Diclonius daughter.
  • A Glass in the Hand: Thinking about Kisaragi and her death at Lucy's hands causes him to feel such anger and angst that he breaks a glass he was holding in his hand. The bleeding in his hand doesn't compare to the pain he feels inside.
  • The Heavy: Why does Lucy do what she does? A friend (and her only one) took a bullet for her not knowing Lucy could deflect it so Lucy gave herself in to try and save the friend when Kurama offers to help if she comes quietly. Later Kurama flatly informs Lucy the friend died. She now wants to make him suffer.
    • In the anime, merely informing Lucy her friend died was enough to set her sights on Kurama. In the manga version, Kurama twists the knife by casting aspersions on the girl he killed, and saying that all this was Lucy's fault for not surrendering and the Diclonius' refusal to co-exist with Humans. Needless to say, this inverted accusation has no appeal for Lucy, and explains her single-minded hatred all the more.
  • Heroic BSoD: Mariko's death leaves him shell-shocked for half a year. It takes Nana nearly being killed by a Mariko clone to snap him out of his funk.
  • I Did What I Had to Do: He executes baby diclonius and justifies his actions by convincing himself the babies must be killed before they grow up into murderers.
  • Interrupted Suicide: In the manga, he tries to shoot himself after Mariko dies. He's stopped by Bando who gives him shelter at the beach where he also lives for several months.
  • Living Emotional Crutch: To Nana, who could only withstand all the experiments conducted on her by becoming attached to and wanting to please her "papa".
  • Moral Myopia: He hates most diclonious for their psychotic tendencies and hatred of humanity as a whole, but completely turns a blind eye to the brutal, horrific, and inhumane treatment and experimentation they endure that makes them this way.
  • Necessarily Evil: He sacrifices children and adult women for the sake of saving the human race.
  • The Needs of the Many: He's willing to terminate innocent children and not-so-innocent adult women alike, for the sake of saving the human race.
  • Nice Job Breaking It, Hero: Him shooting Kouta in Lucy's presence was what caused her to almost destroy the world in a callous combination of Revenge and Taking You with Me.
  • Noble Top Enforcer: Unlike Director Kakuzawa who is just evil and plans to make Diclonii take over the world, Kurama participates in the research because he sincerely believes Diclonii are a threat to the world. He also does feel remorse when torturing and killing Diclonii.
  • Offing the Offspring: Kurama was initially in charge of terminating Diclonus children because he was the only one who could do it with no signs of regret. That is, until, his own daughter Mariko turns out to be one as well...
    • Zigzags. Ultimately subverted in the anime, when Kurama dies with Mariko because Mariko explodes rather than him doing anything to her. Eventually played straight-ish in the manga, though Kurama only kills a clone of Mariko and not the real article, with the clone vehemently insisting on not being treated as Mariko.
  • Opaque Lenses: We usually can't see his eyes through his glasses.
  • Outliving One's Offspring: After trying to kill her own daughter several times, Kurama ultimately can't do it. Instead, he watches as Mariko is killed when the bombs implanted inside her blow up while she protects him from Lucy.
  • Parental Substitute: He is the surrogate father of Nana.
  • Red Oni, Blue Oni: A cold and pragmatic Blue to aggressive and hot-blooded Bando's Red.
  • Revenge Myopia: Towards the end of the series, he comes at Lucy with a gun, after she promised not to attack humans anymore, for all the grief she gave him, but then who captured her, locked her up in a vault, and not only had her undergo horrific experiments, but is directly responsible for sending an army at her and killing her best and only friend in front of her eyes when she was a child, and blamed her for it?
  • Scary Shiny Glasses: He's shown with them very often.
  • Sensitive Guy and Manly Man: Him and Bando. Though, Kurama is a Badass Bookworm on par with Bando's Badass Normal.
  • Sharp-Dressed Man: He always wears a suit, except during the time of his Heroic BSoD.
  • The Starscream: He secretly tries to prevent Director Kakuzawa from becoming the god of Diclonii.
  • The Stoic: Initially, although less and less as the plot progresses.
  • Together in Death: He attempts this in the manga where he intends to die crushed by a missile with his daughter Mariko in his arms. However, both survive and then he watches Mariko blow up while protecting him from Lucy. In the anime, however, he succeeds to die with Mariko when he holds her in his arms as the bombs inside her explode.
  • The Unfettered: Kurama's goal is to save the human race, even if it involves terminating innocent children and women alike.
  • Villainous Rescue: In the anime, he saves Lucy from a No-Holds-Barred Beatdown by Mariko.
  • Would Hit a Girl: He slaps Lucy with enough force to knock her off her feet. Given that she had just dismembered Nana, it's justified.
  • Would Hurt a Child: Considering that he's tasked with euthanizing diclonius newborns.

Kurama's young, clumsy secretary who has worked for him for at least five years and admires him. She's killed by Lucy early in the series, just to mess with Kurama.

  • Bulletproof Human Shield: While escaping during the first episode, Lucy decapitates Kisaragi and uses her corpse to block a hail of 9mm bullets. In the manga, Kisaragi is made Lucy's human shield even before her decapitation.
  • Cute Clumsy Girl: Messily deconstructed. Despite being one of the few characters with any significant dialogue in the first episode, she gets her head ripped off ten minutes in.
  • The Ditz: Deconstructed.
  • Misplaced Kindergarten Teacher: She's akin to this; she's clearly out of her depth working in the facility she does and doesn't seem to understand the magnitude of what she's involved with, if her delayed reaction to a naked, rampaging Lucy is anything to go by. Kurama's affections aside, how she lasted as long as she did on the job before her fatal encounter with Lucy is a mystery.
  • Off with Her Head!: Courtesy of Lucy.
  • Too Dumb to Live: The moment she saw the devastation that was being caused one would have expected her to realize that a noncombatant like herself should do the smart thing and get to the exit ASAP. Then again, this being Lucy, it wouldn't have been useful at all...
    • This is not the case in the manga version, where Kisaragi comes across Lucy before seeing any devastation and death from her, and is thus at the wrong place at the wrong time when Kurama and his guard squad arrive on the scene. Cue Bulletproof Human Shield and Off with Her Head!.

  • Half the Woman She Used to Be: Lucy rips her in two in the anime.

  • The Mole: Preceded the Agent in this regard, sending enough information to her superiors for them to realize the gravitas of the situation and send in the second.
  • Subordinate Excuse: To Kurama.
  • Sex Slave: In the manga, she's a sex slave to Director Kakuzawa to get information from him.
  • Sexy Secretary: To Kurama. Director Kakuzawa even usees her as a sex slave.
  • Unbalanced by Rival's Kid: In the manga, it was her idea to implant bombs within Mariko's body, not Kurama, who was unaware of it. The reason? It was a child from another woman.
  • Uriah Gambit: Sending Mariko in to fight Lucy was her idea. They were counting on Mariko winning, and even if she didn't, it wouldn't be a total loss. The Director accuses her of doing it to destroy parts of Kurama's past life so he'll let it go and move on. Her reasons for doing it are likely a combination of that, risking less human lives, and trying to divert suspicion from her The Mole Status.
  • Too Dumb to Live: In the anime, she gets too close to Lucy while trying to explain to Kouta who she really is, putting herself within range of Lucy's vectors. It proves a fatal mistake.

  • Adaptational Villainy: Manga Isobe was a troubled individual who tried to see the differences in Diclonius. His own niceness in fact is what got him killed. Anime Isobe not so much and comes off as another typical arrogant human.
  • Asshole Victim: Anime only, due to Adaptational Villainy.
  • Evil Makes You Ugly: Due to Adaptational Villainy, his entire character design was changed, who looks much less attractive than his average looking counterpart.
    • Although, the first episode features a man with a brown suit who looks more like the manga-Isobe; apparently the staff of the anime studio changed their mind. It's also possible that they transfered Isobe's role into a new unnamed anime character.
  • Killed Mid-Sentence: In the anime, when Isobe attempts to shoot Nana, but he is killed by Lucy.
    "You're the only one left. Think of the reward—" (gets decapitated)
  • No Good Deed Goes Unpunished: Tries to save Mariko from blowing up when he thinks she's had a change of heart. She plays with his emotions and after getting what she needs, callously beheads him.

  • Off with His Head!: How Lucy (Anime) and Mariko (Manga) kill him.

    Professor Kakuzawa 
Voiced by: Hiroaki Hirata (JP), John Swasey (EN), Mauricio Pérez (Latin American Spanish)

Son of Director Kakuzawa and a collegue of Kurama. He has the same goal as his father.

  • Attempted Rape: On Lucy. He failed.
  • Bald of Evil: His hair is really a wig to hide his Diclonius horns. Lucy kills him for trying to rape her.
  • Big Bad Wannabe: He plans to overturn his father and take over the world himself. Lucy kills him before he can even try it.
  • Devil in Disguise: Literally and metaphorically: His horns are hidden under a wig and nobody knows of his plans to destroy humanity.
  • Failed a Spot Check: It never occurred to him that the drugs he used on Nyuu had only knocked out that aspect of Lucy's split persona, not Lucy herself as he intended.
  • Godhood Seeker: Like his father, he wants to become a god after the Diclonii rule the world.
  • Hide Your Otherness: He wears a wig to cover the horns on his head.
  • Killed Mid-Sentence: Lucy kills him when he's telling her that he's going to rape her and wants to create a new race.
    Kakuzawa: "Lucy, it's different for you. You're the pure one that I've been—" (cue decapitation)
  • Mad Scientist: He wants to destroy humanity because For Science!.
  • Medical Rape and Impregnate: He's planning to rape and impregnate Lucy so he can produce more Diclonii children. Lucy kills him before he can go through with it.
  • Off with His Head!: Lucy beheads him.
  • The Starscream: To his father, wanting to rule the Diclonius race in his own name. He fails.
  • Too Dumb to Live: His entire scheme to rape with Lucy is incredibly carelessly planned, but his fruitless appeals to her that they're on the same side when the drugs woke her from her Nyuu state were even more idiotic. Even when she's clearly in no mood to listen to a word of what he has to say, he still insists that they're destined to mate and carry out their task of wiping out the human race. That's right, even after trying to rape her, he has the audacity to insist they're allies; Lucy is quick to set the record straight with him.

  • Action Survivor: At the end of the manga, she survives the riot of the clone Silpelits.
  • Chekhov's Gunman: In the manga finale, she ends up finally creating the Diclonius vaccine.
  • Girlish Pigtails: She wore two braids in her middle school life. The boys view her as unfeminine and ugly, though.
  • Hot Scientist: She actually looks pretty good. She has a lot of Panty Shots and later goes only with a shirt and panties.
  • Identical Stranger: A weakened Diana mistakes Arakawa for Nousou, probably because of their similar hair style. This actually saves her life and allows her to command Diana.
  • Mad Scientist: Arakawa starts out as only slightly eccentric when she has to take over his work. Being practically locked in in a basement room on a small remote island and working alone for weeks really tooks it's toll from her.
  • Nerds Are Sexy: Averted in her backstory, as she was considered ugly by the boys.
  • The Pig-Pen: She states she hasn't taken a bath in over a week, even considering that, now that she's working in the Facility, she should take a shower at least every three days.

  • Dying Moment of Awesome: Despite losing the lower half of her body, Saito manages to push the bomb button and blows Mariko's right arm off, just before she dies.
  • Girlish Pigtails: She wears two braids that gives her a girlish vibe.
  • Good Parents: She seemed to want to be this to Mariko in the anime, but sadly Mariko had other ideas. Saito spends her last few moments of life putting an end to Mariko's rampage.
  • Grievous Harm with a Body: Mariko throws her torso at the person who is about to push the button. This becomes unfortunate for Mariko.
  • Half the Woman She Used to Be: How she is killed by Mariko.
  • Horrible Judge of Character: She insists she genuinely cares for Mariko, who's she's overseen for most of her time spent in the facility. Mariko however felt no such attachments in return and her first instinct it to brutally murder Saito. Realizing her fatal error in judgement, she blows off one of Mariko's arms just before she dies.
  • Like a Daughter to Me: She claims to love Mariko like she's her real child.
  • Manipulative Bitch: In the manga, Kurama's assistant Isobe learns that Saito manipulated Mariko with the lie that neither birth parent wanted her, when her mother definitely did, and her father made a devil's deal to keep her alive.
  • Not Quite Dead: After being blown in half and thrown through a window, she uses her last few seconds of life to press the button to detonate the bomb in Mariko's right arm.
  • Parental Substitute: She thinks of herself as this to Mariko, having been the only human contact the girl had been subjected to during her imprisonment. Mariko disagreed.
  • We Hardly Knew Ye: She's killed very quickly after her introduction.

    Anna Kakuzawa
The daughter of Director Kakuzawa, who is turned into a "goddess" with precognition powers.
  • Anti-Villain: The "Villainess in Name Only" variant. If it wasn't for her father, Anna would probably be one of the sweetest characters in the manga.
  • Black Sheep: The only member of the family who has a low intellect and no talents. Her human form only.
  • Book Dumb: Was this before her father experimented on her.
  • Eldritch Abomination: A massively engorge brain several tons and capable of predicting the future. Ironically more Eldritch than Abomination and ultimately she returns to her normal form at the end of the manga.
  • Even Bad Women Love Their Mamas: The Anti-Villain variation. She genuinely loves her father. Indeed, the reason she helps her father is out of love and a desire to be useful to him. Unfortunately the feeling is no longer mutual.
  • Evil Genius: Subverted. While a genius in her goddess state, Anna can hardly be described as evil (At least not in comparison to her father or some of the other questionable people) and only wishes to help her father out of a need to support him and prove herself. Ironically this was subverted entirely in her human form where she is neither evil nor a genius.
  • Redemption Equals Life: Played with, in the end Anna does nothing to actually redeem herself. However at the same time out of all the antagonists she is perhaps the least evil and thus remains the only Kakuzawa to survive the end of the manga.
  • Seers: Her goddess form has precognition powers. Actually it's just very complicated and long math.
  • Tom the Dark Lord: A very horrifying Eldritch Abomination goddess with the name Anna.
  • Unexplained Recovery: She somehow returns into her human form after Lucy destroyed her goddess form. Though, there is an implication that her father had something to do with it.
  • Was Once a Man: She was born as a sweet young girl who loved to run, but thaks to her father experiments, she transformed into a horrible creature who couldn't support her giant head She recovers at the end.
  • "Well Done, Daughter!" Girl: She goes through some horrific experiences because she wants to be useful and appreciated by her father.
  • White Sheep: The only kind person in her family.

    The Unknown Man

A minor manga-only character, a man clad in a black trenchcoat and wide-brimmed hat, with opaque sunglasses and greasy-looking hair. At first appears relatively civil, he soon reveals his true colors as one of most horrifically evil bastards, if not the most evil, in the entire series. A brutal, heartless, Hidan-level sadist, rapist, and all-around not very nice man, he delights in causing pain and suffering, especially in Diclonius and/or teenage girls.

  • Abnormal Ammo: Let's just say that heavy spiked balls coated in potent toxins isn't exactly what you'd expect a crossbow to fire.
  • Agony Beam: A low-tech variation, in the form of a crossbow that fires spiked metal spheres coated in a toxin that causes horrible, cripplingly agonizing pain to those it hits. Bites him in the ass - literally - during his fight with Bando.
  • Ambiguously Human: He's heavily implied to be the same species as Kakuzawa (a horned human), however we never see him without his hat.
  • Attempted Rape: He tries to rape Mayu. Bando stops him.
  • Ax-Crazy: Perhaps the craziest. And considering the likes of Bando and Lucy, that's saying something.
  • Badass Longcoat: He wears a dark long coat, similar to Alucard.
  • Dirty Coward: He gleefully tortures and rapes defenseless Diclonii and normal children, but runs away when he confronts Bando.
  • Even Evil Has Standards: He is shown disgusted at what Kakuzawa had done to his daughter. However considering his later actions, it seems to be subverted.
  • Eviler Than Thou: Definitely worse than Bando and/or Lucy, and arguably worse than even Kakuzawa Sr.
  • Eye Scream: He tries to shoot Mayu's eye out with his crossbow to punish her for resisting him. Bando intervenes just in time.
  • Hate Sink: Even though he doesn’t appear much, his actions mark him as one of the most detestable pieces of human trash in the story.
  • Nice Hat: In tune with his "Alucard wanna-be" appereance.
  • No Name Given: This arguably just makes him worse.
  • Off with His Head!: Courtesy of Lucy.
  • Psycho for Hire: Less Hammy than Bando, but much more sadistic.
  • Rape Is a Special Kind of Evil: He rapes Number 28 offscreen and tries to rape Mayu only for Bando to give him the beating he deserves. It's also implied that he was allowed to rape many more Silpelits by the staff of the facility.
  • Sadist: Oh yes. He greatly enjoys inflicting pain on others and frequently tortures and rapes for fun.
  • The Sociopath: He gleefully rapes and mutilates Diclonii, nearly kills Wanta, and threatens Mayu with not just rape, but disfigurement.
  • Sinister Shades: His sunglasses make him look like Alucard.
  • Sunglasses at Night: Like Bando and The Agent.

    Dr. Nousou

The head scientist of Chief Kakuzawa after Kurama's departure.

  • Abusive Dad: He's the creator of over a thousand failed Mariko clones, who were the victims of his horrible experiments and were killed en masse to have their organs harvested. Even the four perfect clones he grew attached to were not spared, as he implanted mind-control devices in their heads and forced Diana to stab herself in the heart to prove her obedience. After having her device removed, Barbara makes it clear how much she hates him for torturing her and her sisters, before she slices his head off.
  • Bishōnen: Just look at his face!
  • Dissonant Serenity: He performs brutally horrific experiments on Diclonii while having a calm expression all the time.
  • Dude Looks Like a Lady: He has a similar face and hair style to Arakawa, just having light hair and mirrored bangs. This becomes a plot point, when Diana mistakes Arakawa for him.
  • Even Evil Has Loved Ones: As horrific as his experiments are, he really loves Alicia, Barbara, Cynthia and Diana.
  • Heel–Face Door-Slam: After the Mariko clones sacrifice themselves to protect him, he starts having second thoughts about the research facility's inhuman treatment of the Diclonii. He frees Barbara from her mind control device to give her back her free will. Barbara then rips his head off as revenge for his abuse towards her and the other clones.
  • Heel Realization: He feels regret over his tortuous experiments after realizing he loves the clones of Mariko he created as if they were his daughters.
  • Identical Stranger: His appearance looks very similar to Arakawa.
  • Karmic Death: He's ultimately killed by Barbara when he removed the mind-control device of her, letting her release all the hatred she felt for how he treated her and other clones so cruelly.
  • Long-Haired Pretty Boy: He's a feminine-looking man with long hair tied back in a ponytail.
  • Morally Ambiguous Doctorate: He's an amoral scientist who performed unethical and Body Horror level experiments on Diclonii.
  • No Good Deed Goes Unpunished: Releasing Barbara from his control might have been the right thing to do, but it definitely wasn't the smart thing because she proceeds to kill him almost immediately now that she can feel the full extent of her hatred for his abuse towards the clones.
  • Oral Fixation: He usually has a pocky on his mouth.
  • Parental Favoritism: If the clones he created can be considered his "daughters". He loves the four perfect clones that he created, but coldly murders the failed ones and harvests their organs.
  • That's an Order!: He orders Alicia and Barbara to let him die so they would survive and could capture Lucy. They refuse to do so. While Alicia dies, Barbara manages to save him, and Lucy is captured thanks to Cynthia and the Agent.

    The Agent

An ambiguously looking operative that goes alongside Nousou at the assault of Maple Inn. Is the one that knocks Lucy out and brings her back to the facility.

  • Anti-Hero: She really is trying to save the world. She'll willingly sacrifice innocent lives if it means getting her job done, though.
  • Badass Normal: The only person to defeat Lucy. Even though it was a cheap shot.
  • Bifauxnen: The Agent was confused for a man for almost all of her appearances, but was revealed as female at the very end, where her shirt rips, and reveals her cleavage.
  • Combat Pragmatist: She will use any means to win.
  • Cool Shades: She wears shades to match her coolheaded personality.
  • Double Agent: She works for the Japanese goverment and was sent to Kakuzawa as a spy.
  • Hesitant Sacrifice: After she stays behind to help Dr. Arakawa escape the island, she cries before the Diclonii seemingly kill her and she says she does not want to die. She's later revealed to have survived, though.
  • Hidden Depths: Introduced as a replacement for the former hunters (the aforementioned Bando, and the Unknown Man), and at first acts as a quieter and less sadistic hunter. Eventually she's revealed to be a government agent sent to shut the facility down, she's also quite the Determinator, and shows she's willing to die if it helps to save humanity.
  • No Name Given: Her name is never mentioned.
  • Not So Stoic: Stays behind to face certain death so Arakawa can escape with the Diclonius vaccine. Starts crying as soon as Arakawa is gone.
  • Shoot the Dog: To keep up the illusion of her loyalty, she shoots Kouta when he pulls a gun on Nousou.
  • Sunglasses at Night: Just like the rest of the 'Hunters'.
  • The Stoic: She's a very serious person and shows few emotions.

Diclonii and Silpelits

Voiced by: Tomoko Kawakami (JP), Luci Christian (EN), Cristina Hernández (Latin American Spanish)

Also known as Number 35, she is a young Silpelit girl. She is regarded as the most powerful of the Silpelits, possessing 36 vectors with an approximate range of 11 meters each in the anime (the number and range is much higher in the manga).

After her mother's Death by Childbirth, Mariko was imprisoned as an infant. Her physical impairment is seen in her atrophied limbs as she moves around in a wheelchair. Despite the environment she was raised in, she is relatively well developed psychologically (for a given degree of "psychologically"), unlike Nana. She is extremely homicidal and sadistic, and enjoys torturing and dismembering her victims. However, her personality is not blatantly evil: she is only having fun, and the pleasure she gets from it is equivalent to a child playing with toys, not really noticing the differences.

  • Adaptation Dye-Job: Played with. Due to weird lighting, she seems to be blonde in the anime for most of her early appearance, but outside the funky sunset light (which would need to contain an enormous amount of dust to have that effect, by the way) she's got the classic Diclonius pink hair.
  • An Arm and a Leg: Her right arm gets blown off by one of the many bombs implanted in her body.
  • Artificial Limbs: She gets a prosthetic arm in the anime before being sent out to hunt Nana down.
  • Ax-Crazy: Extreme emphasis on crazy.
  • Blank Slate: In the manga, after being flattened by a huge-ass missile, Mariko temporarily takes on a Nyu-esque persona, even down to only being able to say "Myu". She snaps back to normal when Lucy shows up.
  • Blonde, Brunette, Redhead: In the manga, she's the blonde to Nana's brunette and Lucy's redhead. The anime averts this by making them all pink-haired.
  • Calling the Old Man Out: In a rather emotional scene, she berates Dr. Kurama for treating Nana as his daughter while allowing Mariko herself to be imprisoned in a dark and lonely room with almost zero human contact for her entire life.
  • Creepy Child: She strips Nana and tears off her prosthetic limbs, all while laughing like a kid that finds it fun to crush an insect.
  • Crocodile Tears: She starts crying in front of the man holding the phone that controls the bombs inside her body, all in order to gain his sympathy and get him to tell her the code to stop the bombs from blowing off.
  • Cry Cute: When she meets her father, she cries true tears.
  • Curbstomp Battle:
    • In the anime, she utterly dominates Lucy. In the manga? Not so much...
    • She actually easily takes care of Lucy in the manga as well and its only thanks to the cell phone timing Mariko's bombs and getting her off guard that Lucy is able to get the advantage.
  • Cute and Psycho: She laughs adorably just as she has fun hurting and humiliating Nana.
  • Cute Is Evil: Compared to the other characters, her design screams cute, and yet she is a psychotic maniac.
  • Dies Differently in Adaptation: In the manga, Mariko pulls a Heroic Sacrifice to save Kurama from Lucy, using the explosion that kills her to damage Lucy's horns and repress the Lucy personality. In the anime, she and Kurama die together after he orders an assistant to detonate the remaining bomb inside of Mariko's body while he's hugging her.
  • Dying Declaration of Love: Just before the bomb inside her goes off, Mariko tells her father that she loves him.
  • Enfant Terrible: She's the most dangerous of the Silpelits with an extra helping of Ax-Crazy, who sees killing as a game. She's also about five years old.
  • Evil Cripple: She has spent most of her life in isolation and has extreme atrophy in her legs, so she has to get around in wheelchair.
  • Explosive Leash: Taken to an extreme. She has multiple bombs planted in her body set to go off every 30 minutes if a specific code does not get constantly transmitted. It was set off once when she started going out of control, and was also used to keep her under control, since she couldn't use her vectors if she was in that much pain.
  • Extremely Protective Child: After Mariko realizes her father does love her, she's determined to protect him no matter what, even sacrificing her life to protect him from Lucy.
  • Face of an Angel, Mind of a Demon: Mariko looks like an innocent, cute girl, but she's an Ax-Crazy Silpelit. This is even invoked by her in the manga, when she tries to get the code from Isobe.
  • Faux Affably Evil: She tries to get sympathy from adults and later kills them.
  • Freudian Excuse: The reason why she became evil is because she's captured in a dark cage since her birth and is left alone by her own parents (or better said, her mother died and her father Kurama left her in the hands of those who put Mariko in the dark cage).
  • Go Out with a Smile: In the anime, as Kurama takes her for a walk, they tearfully reunite with him promising never to let her go again. The bombs inside of her go off shortly afterwards, killing both of them.
  • Green-Eyed Monster: She's jealous of the father-daughter relationship between Kurama and Nana, feeling angry and sad that her father could raise another Diclonius girl while he left her to be imprisoned.
  • Handicapped Badass: Being wheelchair-bound and having only one (real) arm doesn't stop her from curb-stomping Lucy.
  • Heroic Sacrifice: In the manga, she charges a now-quite-unhinged Lucy and gets right next to her, allowing herself to be killed just in time for the explosives implanted in her to go off. The explosion knocks Lucy's horns off and causes her to regress to Nyu, thus saving Dr. Kurama from Lucy.
  • Hime Cut: Mariko has blunt bangs, chin length sidelocks, and mid-back length straight hair. It signifies her sweet and innocent facade.
  • I Just Want to Be Loved: All she ever wanted was receiving the love from her parents.
  • Improbable Age: 5 years old. And the strongest Silpelit.
  • Kids Are Cruel: Mariko is this to a certain extent, as her ruthless killing is more or less the Diclonius equivalent of burning ants with a magnifying glass (at least the way she treats it). Of course, she wasn't really raised to know any better...
  • Lack of Empathy: She's a borderline Sociopath.
  • Laser-Guided Karma: She throws Saito's torso at the person who is about to push the bomb button. Unfortunately, Saito is still alive at this moment and pushes the button herself, resulting Mariko's loss of her right arm.
  • Light Is Not Good: Compared to Lucy and Nana, Mariko has light hair and wears light clothing, and is enormously insane.
  • Little Miss Badass: The strongest Silpelit is also the smallest and youngest.
  • Love Redeems: Her father showing her affection is all that's needed for her to stop acting evil and choose to protect her father even if it costs her her life.
  • Naked on Arrival: Like any other Diclonii, she's introduced completely naked, but had a helmet.
  • One-Word Vocabulary: When suffering temporary amnesia, the only thing she says is "Myu".
  • Pet the Dog: In the manga, she tells Nana to protect their father before going off to fight Lucy.
  • Raised in a Lab: She was raised inside a steel container with human contact consisting of nothing more than a scientist acting as a sort of foster mother through speakers and monitors.
  • Sadist: She finds enjoyment in putting Nana through torture and humiliation just because she can. She's compared to a child that makes a game out of crushing insects.
  • Slasher Smile: Like any other evil Diclonius.
  • Stepford Smiler: An extreme Type C example.
  • Together in Death: In the anime, she dies together with her father after he orders his subordinate to activate the bomb inside Mariko while he's holding her.
  • Too Powerful to Live: She's the most powerful Silpelit ever born. It's no surprise she doesn't live past one story arc.
  • World's Strongest Woman: She is the strongest Silpelit in existence.
  • Yandere: Though not as bad as Lucy, she still beats the tar out of Nana in a fit of jealousy upon hearing her call Kurama "Papa". In the manga, she gets over this before her death and actually tells Nana to take care of "their Papa" for her.
  • You're Not My Mother: Mariko says this to Saito right before killing her.

    Number 3 
Voiced by: Mikako Takahashi (JP), Allison Sumrall (EN), Hiromi Hayakawa (Latin American Spanish)

A minor character present in Dr. Kurama's backstory. She is mainly known for allowing Kurama to figure out how Diclonii are born.

  • The Gloves Come Off: She hides the true strength of her vectors so she can catch the scientists off-guard and escape containment.
  • Naked on Arrival: Like most other Diclonii, she is completely naked when we first see her.
  • Pet the Dog: Even though she kills everyone she meets at the facility, she makes a special occasion to visit Kurama to thank him, and she spares him for showing the closest thing to sympathy she had ever seen.
  • Small Role, Big Impact: She only appears for a brief period in Kurama's backstory, but she plays a pivotal role there. When she goes to meet Kurama, she sticks one of her vectors into his and Oohmori's head. When both of them end up siring Diclonii, Kurama finds out how they infect people with The Virus.
  • We Hardly Knew Ye: She is killed off in the backstory after very little screentime.

    Number 28 
A relatively minor manga-only character, 28 is mainly known for the nauseatingly horrific fate she suffers at the hands of the Unknown Man.
  • Half the Woman She Used to Be: Everthing below torso amputated so she becomes portable in a bag.
  • Muggle Born of Mages: Despite being a Diclonius, she is unable to generate vectors. That doesn't stop the Unknown Man from torturing her anyway.
  • Naked on Arrival: Like any other Diclonii, she's introduced completely naked.
  • No Name Given: We only know that she's called "Number 28".
  • People Jars: Is carried within a container by the unknown man, only in a much worse fashion.
  • Rape as Drama: Courtesy of the Unknown Man.
  • The Voiceless: She doesn't get any spoken lines before the Unknown Man first gets his hands on her, and afterward she can't speak because the bastard ripped her vocal chords out.

    Alicia, Barbara, Cynthia & Diana 

The four are the only successful clones of Mariko, created by Doctor Nousou, but they are physically older than their original. Each of them have a mind-control device inside their forehead that prevents them from going amok and makes them peaceful. Nousou has perfect control over them and they listen only to him, but sometimes they do not if they try to save his life. The clones are used to capture Lucy.

  • Adapted Out: They do not appear in the anime.
  • Alphabetical Theme Naming: Their names start with a letter from A to D: Alicia, Barbara, Cynthia and Diana. Furthermore, their names end with an A.
  • Anti-Villain: Due to the mind-control devices, their evilness is surpressed and they are sweet girls who are working for the villains. Barbara subverts this later, and Diana for a few seconds.
  • An Arm and a Leg: Lucy throws stones to torture Alicia, dismembering her an arm and a leg. Then, Lucy beheads her.
  • Badass Adorable: They are Mariko's clones after all, the strongest Silpelit.
  • Badass Arm-Fold: Barbara does this a few times after she's out of control.
  • Berserk Button: Barbara does not like being addressed as Mariko, vehemently insisting that she is her own individual person.
  • Berserker Tears: Barbara cries for her dead failed clone sisters when she kills Nousou.
  • Chekhov's Gunman: Diana is demoted to stay back because of her Game-Breaking Injury. She shows up later, when Arakawa is in danger.
  • Cloning Blues: They are clones of Mariko. This has a terrifying effect on an already beyond-broken Kurama when he finds Cynthia, who dies in his arms, and Barbara, who claims not to be Mariko.
  • Cool Helmet: Each of them wear helmets similar to Lucy's, but the number of eye holes depends on the one who wears it. Alicia has one on both sides, Barbara has two, Cynthia has three, and Diana has four.
  • Cry Cute: Diana cries after stabbing on her arm. Cynthia cries when she's ripped apart by Lucy, and Barbara and Alicia cry because of that event and later when they try to save Nousou.
  • Defusing The Tykebomb: After his near death experience, Nousou considers whether the girls could live a normal life or not.
  • Determinator: Alicia and Barbara do not give up to save Nousou, regardless of the pain the have to feel or the danger they in there.
  • Died in Your Arms Tonight: Cynthia dies in Kurama's arms, who mistakes her for Mariko. Coincidently, it is night when it happens.
  • Divergent Character Evolution: Not in terms of characterization, as they all share the same personality, either with or without Mind-Control Device. But they are distinct in their roles for the plot, with each of the four girls fulfilling a different purpose to advance the story.
  • Does Not Like Shoes: For some reason, Barbara does not wear shoes when she's in hospital with Nousou, resulting that she goes (and "flies") barefooted after she leaves it.
  • Expendable Clone: Ordering a Diana to stab herself in the heart to prove a point isn't the worst thing done.
  • Game-Breaking Injury: Nousou orders Diana to stab into her heart. She gets better, thanks to a replacement heart, but this injury makes her useless for the mission to capture Lucy, that's why she stays in the labor. This is fortunate for Arakawa, who is later saved by her.
  • Half the Woman She Used to Be: Cynthia is cut in half by Lucy. Not only reminds this Kouta of Kanae's death and brings his memories back, it does not kill her instantly.
  • Handicapped Badass:
    • Cynthia manages to break one of Lucy's horns, despite being cut in half.
    • A weakened Diana manages to kill several other Silpelits before being killed herself.
  • Heroic Sacrifice: Alicia and Barbara disobey Nousou's order to capture Lucy or run away, but they decide to save him from being crushed by a helicopter. Lucy uses the opportunity to attack them with objects, since she is out of their range. Alicia gets killed by her, and Barbara still disobey Nousou and jumps in front of him to tear the helicopter above him apart, since the clones' vector's ends are weaker.
  • Hope Spot: Diana becomes one for Arakawa and the Agent. But not for long.
  • In the Back:
    • Lucy keeps attacking Alicia and Barbara from behind, who are trying to save Nousou from being crushed by a helicopter. This ultimately kills Alicia.
    • Barbara is shot in the head by Kurama from behind. He comments that she probably noticed his gun and he wonders why she didn't dodge or something.
  • Killed Off for Real: All four of them die during the course of the story, but under different circumstances. Cynthia is cut in half and dies a few minutes later after that. Alicia is beheaded by Lucy before Cynthia finally dies. Barbara is shot in the head by Kurama. And Diana is beheaded by one of the random clone Silpelits.
  • Made of Iron: They are specially modified for being able to use their vectors regardless how much pain they feel.
  • Mind-Control Device: They have these in their foreheads, that prevent them from being evil. They are under Nousou's control.
  • Naked on Arrival: When they are introduced, they wear nothing but helmets.
  • Not Quite Dead: Cynthia is not immediately killed after being in cut in half by Lucy. With the help of the Agent, she is able to break one of Lucy's horns. Unfortunately, Kurama finds Cynthia, mistaking her for Mariko, and she dies in his arms.
  • Not Quite Flight: Barbara uses her vectors to move her in the air like she could fly. Combined with Badass Arm-Fold, it looks cool.
  • Off with Her Head!: Lucy beheads Alicia with a stone monument. Diana gets beheaded by one of the random clone Silpelits.
  • One-Word Vocabulary: Under mind-control, the only thing they can say is "Myu" (and "Papa"), just like Mariko under her temporary amnesia.
  • Our Clones Are Identical: They all look identical with each other. In comparison to their original Mariko, they look older.
  • Replacement Goldfish: Cynthia becomes this to Kurama, despite it's only her upper half of her body. And when she's dead. Kurama gets the same reaction when he meets Barbara.
  • Send in the Clones: They are sent to capture Lucy.
  • Sibling Team: They are created to capture Lucy. But because of Diana's Game-Breaking Injury, the team consists only of the three when they mission starts.
  • Single-Minded Twins: They all have the same personality.
  • Slasher Smile: Barbara and Diana when they are out of control.
  • Spy Catsuit: What Alicia, Barbara, and Cynthia wear during the mission.
  • This Is Unforgivable!: Barbara does not forgive Nousou for his experiments on the failed clones, whom she considers as sisters. Even when he apologizes for this.
  • Trademark Favorite Food: Like Nousou, they like pocky.
  • Turned Against Their Masters:
    • Nousou removes Barbara's mind-control device to find out if she's really not an evil monster and does love. He's wrong and this costs his life.
    • Arakawa does the same to Diana, though Arakawa is not aware of the purpose of those devices. Fortunately, the Agent puts them back into Diana's forehead before anything could happen.
  • Tyke-Bomb: They are the research's "weapons" that are barely treated as people. Initially.
  • Undying Loyalty:
    • Diana stabs herself into her heart with knive to prove how loyal the four are to Nousou.
    • Alicia and Barbara disobeyed Nousou's orders to save his life, even at the cost of their own. Later, Nousou tests if it's really the girls that saved him or the mind-control devices. It's the latter.
  • Walking Spoiler: They are Mariko's clones. Of course that's a spoiler.
  • Younger Than They Look: They are only a few months old at most, but they look physically older than Mariko, being in their puberty. Since Silpelits age double as fast as humans, and clones of in general age faster than their originals, this combination justifies this trope.

    The Clone Diclonii 

A collection of over 1,100 Diclonius clones of Mariko created by Nousou, at the Diclonius Research Institute. Unlike their four "sisters", Alicia, Barbara, Cynthia and Diana, they are physically deformed and are mainly created for the purpose of having their organs extracted.

  • Adapted Out: They do not appear in the anime.
  • And I Must Scream: Kept in deplorable conditions for their entire lives before being killed and having their organs extracted.
  • Body Horror: They are imperfect clones of Mariko with severe physical deformations.
  • Brown Bag Mask: Which hide their deformed faces.
  • The Dog Bites Back: After sensing Lucy's presence, they blow up the Institute with their vectors, kill nearly all the researchers, and nearly destroy the anti-Diclonius vaccine. They are only stopped by the efforts of the Agent.
  • Expendable Clone: Unlike the other Diclonii at the facility, they are not given names or even numbers. Their only purpose is to be killed for their organs.
  • Extra Eyes: Some have three or even four eyes, as seen by the holes in their masks.
  • Facial Horror: Their faces are never seen, but are so horrifically deformed that they have to be covered by cloth sacks.
  • It Can Think: Nousou describes them with "failures without even a human countenance left", but the fact that they specifically tried to destroy the anti-Diclonius vaccine suggests that they could tell what it was for.
  • Naked on Arrival: Noticing a pattern?
  • Organ Theft: The failed clones' organs are harvested for research and anti-Diclonius weapon development.
    "We have a serious need for the spinal cords of these girls."
  • Powered by a Forsaken Child: Their organs and spinal cords are used to create anti-Diclonius weapons.
  • Walking Spoiler: Similar to Alicia, Barbara, Cynthia and Diana, in that they're Mariko's clones.

    Spoiler Character 

The Male Diclonius

The only male Diclonius and the second one who is not a Silpelit. He's the son of Director Kakuzawa and Lucy's mother, being Lucy's half-brother, who is specially born for impregnating her. He also has a mind-control device in his forehead and is controlled by his father.

  • Brother–Sister Incest: He's born to impregnate his sister, so the pure Diclonii race won't extinguish, and Director Kakuzawa becoming god.
  • Child by Rape: Director Kakuzawa found, kidnapped, and raped Lucy's mother, so he can impregnate her. He meant the boy to be the first of many, but the mother killed herself, and efforts to harvest her unique womb failed.
  • Death of a Child: His own half-sister kills him when he's a mere child.
  • Long Lost Sibling: To his half-sister Lucy. This is justified, since Lucy was abandoned as a baby and he's born much later.
  • Mercy Kill: Lucy kills him together with his father, who controlled him and created him for a single purpose. She feels sorry for him.
  • Mind-Control Device: Like the Mariko clones, he has a mind-control device in his forehead that prevents him from being evil. He's under Director Kakuzawa's control.
  • Naked on Arrival: Averted. Probably because he's not a girl.
  • No Name Given: Makes you wonder if his father even bothered to give him a name. Although depending on how you interpret the text in that chapter, and the Adam & Eve symbolism, Kakuzawa may have named his son Adam.
  • Off with His Head!: How Lucy kills him.
  • The One Guy: The only male Diclonius known to exist.
  • Walking Spoiler: A male Diclonius? Lucy's brother? The circumstances of his birth? His purpose? That's all a Spoiler.
  • We Hardly Knew Ye: He's killed in the same chapter where he's introduced.

Other characters

Voiced by: Joji Nakata (JP), Jason Douglas (series), David Wald (OVA) (EN), Dan Osorio (Latin American Spanish)
An operative for the National Police Agency's Special Assault Team. Although he is technically human, he is as homicidal and apathetic to other people as the worst Diclonius are. He is incredibly skilled in combat and widely-regarded as a lethal and bloodthirsty soldier.
  • '90s Anti-Hero: His design seems to be ripped straight from Duke Nukem, and he certainly has the personality of one.
  • Adaptational Dumbass: Zigzagged somewhat in the anime. Ironically while he was taking several levels of badass and character development in the manga, the anime decided to do the opposite. Though he gets stronger weapons and learns about keeping his distance, his fights in the anime after being mutilated usually involved him kicking his opponent while they're down (and then realizing afterwards he shouldn't get too close) and shooting his gun in the general direction of people and yelling a lot.
  • Adaptational Villainy: While a Jerkass, Bando in the manga was a badass with redeeming qualities to him and character development. The Anime decided to get rid of anything that could make Bando likable while adding more things to hate. The end result was a character who at his best was still worse than Manga Bando at his worst.
  • Anti-Hero: Though unlike Kurama, he kills mostly For the Evulz, or Revenge.
  • Anti-Villain: The Noble Variant in the manga after his character development. He's also kinda this in the anime, though arguably not as much as in the manga.
  • Artificial Limbs: After his skirmish with Lucy, who wouldn't?
  • Ax-Crazy: Not only he is a self-admitted Psycho for Hire, and not only he refuses to personally kill Nyu who can't defend herself, because he can't be arsed to do something so ''boring'', at the beginning, he will smash your face if you as much as try approaching him from the back, even if you are a harmless woman. Though, only at first. He gets notably less crazy later in the manga as a part of his Character Development.
  • Badass Boast: Offers some subtle but still cool lines in the manga and backs up every single one.
    "What are you surprised about stupid? Didn't I tell you that I can never die?" After coming back at the final chapter of the manga after being cut in half by Lucy.
    "You dumbass! Me alone is plenty for the likes of you!" Lucy mockingly tells him and Nana to come at her together. He gives this line and avoids all of her attacks and proceeds to beat the crap out of her.
    • He tries to give one in the anime. "You think I need a gun to kill you? I'll do it with my bare hands." Which might have been incredibly badass had he not been a broken bleeding mess on the ground whom Lucy obviously didn't see any threat and was unable to back his words up.
  • Badass Normal:
    • Takes on several Diclonius including Lucy (twice) Nana and Mariko in the manga and holds his own using nothing but his skills and some heavy bullets and comes close to winning a few of them as well. Not even getting torn in half will stop him.
    • In the manga at least, he, after surviving multiple encounters with Dicolonii, learns how to dodge vectors.
    • He also nearly manages to beat Lucy in his 2nd fight with her, losing because the Unknown Man got in the way, and then because Mayu got in the way.
    • Also when facing the Unknown Man, he gets hit with one of his toxic spiked balls, and he endures the pain and rips it out despite being hooked into his skin with barbs.
  • Berserk Button:
    • Don't litter on the beach, or else.
    • Also, he can't stand pedophiles.
  • Big Damn Heroes: Manga exclusive, combined as it often is with a nice case of Dynamic Entry, when the Unknown Man assaults Mayu and Nana in chapter 75, things look really bad even for this manga.
  • Blood Knight: He refuses to kill Lucy when Nyu is in control because he can't be bothered to do something so boring.
  • Byronic Hero: Chapter78's introduction drives the point home.
  • Character Development: Bando is probably the most Dynamic Character in the series. He goes from a Sociopathic Soldier who joins the SAT to legally kill people who'd give him a challenge, to a less dangerous Jerkass who, while still treating everyone else like utter shit, will still repay people who are in his debt, and is also obsessed with having his Revenge against Lucy, to finally, a Jerk With A Heart Of Brass who risks his life to stop the Unknown Man from raping Mayu in a truly badass manner, but is still obsessed with killing Lucy.
  • Chekhov's Classroom: Bando remembers the instructions given to him earlier in the episode about the 2 meter effective range of Lucy's weapon.
  • Combat Pragmatist: Bando dips into Crazy-Prepared territory, getting his fight with Lucy in a place where he set up, hid traps, and cleared of debris for her to throw.
  • Cool Shades: Very cool.
  • Crazy-Prepared:
    • After getting his ass handed to him by Lucy early on, he completely cleaned up the beach in order to make sure Lucy had nothing to attack with, figured out her range of attack, and got modified Desert Eagles that fired rounds too heavy for Lucy to block or at close range knock away.
    • His crazy preparedness actually works against him in the manga where his attempt to blind Lucy with a flash grenade and tear gas worked against him when the bright flash kept most of the gas from entering her eyes. Though even she admits that if it wasn't for the Unknown Man, he'd have won.
  • Curb-Stomp Battle:
    • He gets the short end of the stick when he meets Lucy.
    • He gives one to the Unknown Man, even though he had his crossbow and Bando didn't use a gun.
    • Having been prepared this time around, his second fight with Lucy in the manga ends with him stomping her face into the ground and nearly killing her twice. Unfortunately, people like to get in the way.
  • Cyborg: He gets a prostethic arm and artificial eyes and a mechanical lower half of his body.
  • Debt Detester: It's his principle to avoid being indebted to anyone, especially to women.
  • Determinator: Through a combination of technology and sheer badassery, Bando walks off stuff that would kill most people. These include getting in order, his legs shot up, one arm ripped off, the other arm snapped, both eyes gouged out, the second arm ripped off and getting bisected. In short, by the end of the manga Bando is a head and chest on life support and isn't slowing down.
    • Grabs hold of a spiked metal ball, which is coated in agony-inducing toxin, out of his body and baseball-pitches it straight into the ass of the guy who shot him with it.
  • Disability Superpower: His prosthetic arm allowed him to remove a spiked ball from his body during his duel with the Unknown Man.
  • Don't Sneak Up On Me Like That!: Bando punched a woman with that excuse.
  • Electronic Eyes: He gets cybernetic eyes after Lucy blinds him during their first fight.
  • Eye Scream: After disabling him during their first fight, Lucy uses her vectors to gouge out his eyes. He did tell her that "the next time I see you, you're dead," so...
  • Flat "What": His expression when Lucy throws The Unknown Man's head at him is priceless.
  • Heroic Sacrifice: Saves Mayu from Lucy during his second battle in the manga and gets cut in half as a result. Unlike most examples he survives. It also completes Bando's character development in the manga.
  • Half the Man He Used to Be: Loses his lower half and his left arm (and his right one, though he lost it earlier, and It had been replaced with a cybernetic arm). He recovers, but with a cybernetic lower half (and arms).
  • Hand Cannon: Bando uses two Desert Eagles chambered in .50AE, and is actually justified in using it: Most handgun bullets bounce off the Diclonius vectors, the heavier and more powerful .50AE round will go right through at a close enough range. The only other option is to use an anti-tank sniper rifle or something equivalent in power.
  • Handicapped Badass: Blurred vision and a dysfunctional hand doesn't stop Bando from kicking extreme amounts of ass.
  • Hidden Depths: A notable example before his character development. After his recovery from his first fight with Lucy, Bando needs some body parts replaced and has to be sterilized (encounters with Vectors make human males carriers of Diiclonius genes). The prospect bothers him as he admits that he had wanted to be a father one day. Also reveals, before his supposed death, that he always wanted someone to cry for him if he ever died.
  • Hitman with a Heart: Despite his intro as a Psycho for Hire and the other times where he acts the part after, he's not all bad, specially towards Mayu.
  • I Owe You My Life: He would have died after Lucy dismembered and blinded him if Mayu haven't found him and called for help. Although he hates owing a favor, he asks Mayu to call him when she needs his help in order to repay her.
  • Intergenerational Friendship: The young teenager Mayu often visits him at the beach and Bando has a soft spot for her big enough as to save from from the Unknown Man.
  • It's Personal: Lucy beats him in a fight, cuts off his arm, and crushes his eyes. He spends the rest of the series wanting revenge on her.
  • Jerk with a Heart of Gold: While he doesn't have much respect for other people and has a foul mouth, he has his moments of decency mainly towards Mayu.
  • Mildly Military: In the anime, Bando has done everything up from threatening other men with guns, to knocking out his own partner to just being a real jerkass overall. Averted to a significant degree in the manga. Bando may say a few threats, but never does more than that.
  • Noble Demon:
    • Bando has lines he won't cross. If he feels in someone's debt he will try to return the favor.
    • And he can't stand the Unknown Man.
    • He may be crazy as fuck, but doesn't like people littering on the beach.
  • No-Holds-Barred Beatdown: Beats the absolute crap out of the Unknown Man which culminates in him shoving the Unknown Man's poisoned spiked ball where the sun don't shine.
  • Pet the Dog: Only when Bando is going through his character development. While his overall attitude doesn't change, his actions certainly do. And by the end of the manga, its almost surprising that he was a near complete monster in the beginning. Some of the things he ends up doing is...
    • Seeing if Mayu is alright after roughing her up.
    • Saving Nana and Kurama from an enraged Mariko.
    • Preventing Kurama from committing suicide and sheltering him.
    • Saving Mayu and Nana from the vicious unknown hunter and keeping his promise to Mayu.
    • Sacrificing himself to save Mayu from Lucy.
    • Treating Nana's wounds from the Unknown Man -knowing she couldn't go to a hospital
    • Giving the deceased Diclonius a proper burial after she's killed by the Unknown Man
  • Pragmatic Villainy: Played With: he claims to clean up the beach because he's preparing for a fight with Lucy, and any and all trash can be used as a projectile. While that is true, he really does hate the litter and wants to keep the beach clean.
  • Red Oni, Blue Oni: An aggressive and hot-blooded Red to Kurama's cold and pragmatic Blue.
  • Sir Swears-a-Lot: Being the tough guy that he is, Bando curses far more than anyone else in the series. What makes it even more noticeable is that all the other main and secondary characters either don't swear at all or only do it once in a while.
  • Staying Alive: He has come back from having one of his arms torn off while the other is broken and having his eyes gouged out by means of cybernetic implants. Later on he is torn in half (by the same character no less) yet returns in the end of the story healthy again (except he's half robot by this point). Somewhat jarring in that he was definitely dead the last time.
  • Sunglasses at Night: Partially justified, as he set up flash bombs on the beach, and he kept the glasses on, on the off chance he'd get into fight.
  • Too Dumb to Live: Instead of just ventilating her, he chooses to play around with her first (a "duel"). In the ensuing fight he manages to accidentally awaken her "Lucy" persona and nearly gets killed.
  • Took a Level in Badass: While hardly weak before, Bando goes through some major changes in the manga after his first defeat by Lucy. His fights afterwards end with him utilizing the knowledge about Diclonius to his advantage, using several good tricks and remaining the only human to fight Lucy twice (and surviving) but actually holding the advantage over her in their second fight and nearly winning.
  • Unexplained Recovery: In his last appearance before the final arc, Bando is ripped in half by Lucy and apparently dies in front of Mayu and Nana. However, the last chapter reveals that he somehow survives, gets prosthetic legs, and reunites with Mayu again. The only implication of how he recovers from a fatal wound is that Kurama might have sent his body to be rebuilt.
  • The Unfettered: Anything is permissible so long as he has the opportunity to kill Lucy.
  • Villainous Rescue: He's a psychopath whose only goal in life is to find and kill Lucy/Nyu, but when the Hunter assaults Mayu, he comes to the rescue.
  • Would Hit a Girl: Most notably on his introductory scene, when he viciously backhanded a woman who made the mistake of approaching him from behind without warning. He outwardly threatens Mayu at one point by citing this trait: see below.
  • Would Hurt a Child: Despite having some standards, he is still more than willing to rough up Mayu and harrass Nana to get some information about Lucy. He also generally treats both girls like utter crap when he's not saving their lives from psychotic Diclonii like Mariko or Lucy or the even more psychotic Unknown Man.

Kouta's little sister who died before the series starts. She was actually brutally slaughtered by a jealous Lucy, and along with his father, serves as the trigger for Kouta's Trauma-Induced Amnesia.

  • Blood-Splattered Innocents: During Lucy's rampage at the festival.
  • Bratty Half-Pint: Kouta certainly viewed her as one, always treating her like a bother to him and not believing her wild claims, both of which he came to regret after she was killed.
  • Cassandra Truth: Her wild story about a horned girl killing people with arms that came out of her head is proven true in the worst way.
  • Clingy Jealous Girl: She became jealous whenever other girls showed attention towards Kouta, as seen when she kicks Yuka.
  • Collateral Angst: She was brutally murdered by Lucy in front of Kouta, and this is what results in his Angst Coma and his attempted revenge against Lucy.
  • Death by Origin Story: Her death at the hands of a jealous Lucy had a major impact on Kouta's life.
  • Death of a Child: She was killed by Lucy while being only a few years younger than Kouta, who was a kid at the time of her death.
  • Did Not Die That Way: She didn't die of illness as Kouta initially remembered. She was brutally murdered by Lucy right in front of her brother and he altered the memory out of trauma.
  • Half the Woman She Used to Be: Her body is torn in half below her lower back by a young Lucy.
  • Little Miss Snarker: She was quite fond of back-talking her big brother.
  • Posthumous Character: She died before the series starts.
  • Small Role, Big Impact: Her death affected much of the present story and characters into being what they were.

Voiced by: Reiko Takagi (JP), Chris Patton (EN), José Antonio Toledano (Latin American Spanish)

The ringleader of the children who tormented Lucy as a child. Tomoo relished in the pain she felt. After he died, he haunted her visions as a spectre to get his Revenge for what Kaede did to him.

    The Orphanage Girl 
Voiced by: Noriko Shitaya (JP), Allison Sumrall (EN), Nycolle González (Latin American Spanish)

A young girl that lived in the orphanage with Lucy. She told the bullies about Lucy's puppy, resulting in them beating it to death and beginning Lucy's Start of Darkness.

  • Accomplice by Inaction: Regardless of whether she truly was part of the bullying or if she truly didn't know just how demented Tomoo and his gang were, the fact that she told them about Lucy's puppy when she explicitly told her it would be bad news and then did nothing to stop it after the fact (not even warning Lucy about her telling them) makes her just as guilty. And that's even assuming she really didn't have anything to do with it.
  • Ambiguous Innocence: It's never made clear if she was actually in on the plot to kill the puppy, or just told the wrong secret to the wrong people. Lucy sees her hiding a smile after she apologizes for the puppy's death, but it is possible that she was imagining it.
  • Death by Origin Story: Along with the rest of the orphanage kids, her death serves as part of Lucy's Start of Darkness.
  • Eye Scream: If Lucy's hallucination of her is anything to go by, the Orphanage Girl was killed by Lucy slamming a vector through her eye.
  • Girlish Pigtails: She wears her hair in two small pigtails.
  • Horrible Judge of Character: Telling the bullies about the puppy makes her this, provided she wasn't really in on the plot to hurt Lucy. What did she think they were going to do to it? In fact, Lucy had explicitly told her that the other boys would hurt it if they found out.
  • My God, What Have I Done?: She's visibly horrified when she sees that the bullies beat Lucy's puppy to death. However, she could have been faking it.
  • No Name Given: She is never referred to by name.
  • Riddle for the Ages: Was the girl really innocent of any crime and simply made a terrible mistake? Or was it all part of their plan to torment Lucy even more? Considering she was exploded by Lucy we'll never know for sure.
  • Slasher Smile: She cracks what could be one after confessing her mistake to Lucy, suggesting that she was in on the plot. Whatever the truth, she had already signed her death warrant.

    Hiromi Kurama 
Voiced by: Akemi Kanda (JP), Luci Christian (EN), Dulce Guerrero (Latin American Spanish)

Kurama's wife, plus Mariko's dead mother.

  • Death by Childbirth: A cruel subversion. She survives giving birth to Mariko, but is left severely weakened and must undergo surgery to save her life. The complications of her weakened state plus the added stress of seeing Kurama try to kill their newborn daughter was what ended up causing her death.
  • Driven to Suicide: Subverted. Earlier in the series, Kurama remarks that she killed herself after witnessing him trying to kill Mariko. During his extended flashback, we learn she had suffered from complications due to the birth because of cervical cancer. She ultimately tries to stop Kurama from killing Mariko, begging him to spare her, causes her sutures to come undone, and ends up bleeding to death on the floor. What Kurama said about her killing herself is how he views what happened.
  • Ill Girl: As said above, she already had cancer when Mariko was conceived and her health got even worse with time.
  • Posthumous Character: She only appears in flashbacks.

    Aiko Takada 
Voiced by: Maria Yamamoto (JP), Allison Sumrall (EN)
A young girl and the second human to ever befriend Lucy.
  • Accidental Murder: When her father tried to cut a painting she made for her mother with a knife, Aiko pushed him away and he ended up accidentally slashing his own throat.
  • Death by Adaptation: While she gets shot in both versions, the manga later revealed she survived by showing a poster of her adult self. The anime doesn't include this.
  • Death by Origin Story: Her death at Kurama's hands lead to Lucy crossing the Despair Event Horizon. Except that she's actually alive.
  • Following in Relative's Footsteps: She wants to become an artist like her mother, even though her mother's art career drove her to leave the family. She does grow to become a famous painter in her adulthood.
  • Kill the Cutie: She was just a little girl who wanted to see her mother again, only to sacrifice her life to save a new friend. Subverted; she actually survived.
  • Morality Pet: She's the first human whom Lucy ever wanted to protect.
  • Nice Girl: She's the second human after Kouta to treat Lucy kindly.
  • Posthumous Character: She died years before the first episode, appearing only in Lucy and Kurama's flashbacks. At least in the anime. A panel in the manga's epilogue implied that Aiko did survive the gunshot and grew to adulthood, unbeknownst to Lucy.
  • Reports of My Death Were Greatly Exaggerated: Kurama told Lucy that Aiko died from her bullet wound. However, this scanlation here states that Aiko survived and grew up to become an artist like her mother.
  • Small Role, Big Impact: Even though she only appears in a flashback, she is the reason Lucy was first captured and the source of her hatred of Kurama.
  • Taking the Bullet: She takes a bullet meant for Lucy from Kurama, which pushes Lucy over the Despair Event Horizon completely.

    Mayu's parents 
Mayu's stepfather is voiced by: Hideo Watanabe (JP), Ty Mahany (EN)

Mayu's mother remarried when Mayu was around twelve or thirteen years old, and the stepfather sexually abused Mayu.

  • The Faceless: Mayu's flashbacks always have their faces hidden in shadow.
  • Hate Sink: Both of Mayu's parents are disgusting, vile people who only exist so the audience hates them. It says a lot that the voice actress for Mayu's mother choose to remain anonymous because of how abhorrent the character is.
  • I Have No Daughter!: They did not report Mayu's disappearance to the police, and Mayu's mother didn't need to think long about giving custody of Mayu to Kouta and Yuka, much to Kouta's surprise.
  • It's All About Me: Mayu's mother, who accuses her own daughter of stealing her husband. And it's evident she got together with this bastard without Mayu's knowledge or blessing.
  • Jealous Parent: When Mayu told her mother about the sexual abuse, the mother expressed jealousy of all the "attention" the stepfather gave Mayu.
  • Karma Houdini: Despite frequently abusing and neglecting Mayu, they receive no punishment for their actions. However, this is mainly because Mayu's mother willingly allows her to stay with Kouta and Yuka at the Maple House.
  • Lecherous Stepparent: Mayu's stepfather sexually abused her.
  • Skewed Priorities: An example that is definitely not Played for Laughs. After Mayu tells her mother what her stepfather has been doing to her, instead of showing concern or trying to help her, Mayu's mother point-blank reveals she only cares for her new husband's attention rather than her daughter's well-being. This is easily one of the biggest reasons she's so loathsome.
  • Unnamed Parent: Neither of them is called by their names and they're Mayu's parents.
  • Why Did You Make Me Hit You?: Mayu told her mother about her stepfather's sexual abuse, but her mother instead hit her and became jealous of all the "attention" the stepfather gave Mayu.

    Nozomi's father

A man who violently opposes his daughter Nozomi's dream of becoming an opera singer like her deceased mother.

  • Abusive Dad: He frequently beats Nozomi to force her to quit pursuing her singing career. He's also to blame for her urinary problems because it was her fear of his anger what caused her to lose control of her bladder.
  • Fantasy-Forbidding Father: He disapproves of Nozomi's dream of becoming an opera singer, due to her being the only heir of his business. The real reason is he doesn't want her to suffer the same fate as her mother, who committed suicide after losing her voice to a throat defect.
  • Unnamed Parent: We never get to know his name, hence he's referred to as "Nozomi's father".

    Nozomi's mother

Nozomi's deceased mother. She was an opera singer.

    Aiko's father

  • Abusive Dad: He frequently beats the crap out of Aiko for drawing.
  • Fantasy-Forbidding Father: He does not want Aiko to be an artist because it reminded him of her mother, who left him because of her career.
  • Unnamed Parent: Like most parents in the series, we don't know his actual name.
