Elfen Lied/Characters

This page lists the characters of Elfen Lied and their associated tropes.

Voiced by: Sanae Kobayashi (JP), Kira Vincent-Davis (EN)
The female protagonist of the series, she is a teenage Diclonius around 18 years old. Lucy has four vectors 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, 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,


 * Adaptation Dye Job: Somewhat. Her hair is more dark and red in the anime, while in the manga it's a pure pink.
 * Ax Crazy: In the manga, at least, Lucy doesn't just nonchalantly tear people to pieces, she does it with a huge grin on her face.
 * Evil Laugh: Manga-only.
 * Anti-Villain Protagonist: Type II. One of the best examples.
 * Also, Anti-Hero: Type V. Particularly, in the anime.
 * Badass: Oh so much.
 * Badass Adorable: When she starts defrosting, she builds up an immense reservoir of Moe.
 * Berserk Button: If she sees you as a threat to Kouta, you will die. Period.
 * Break the Cutie.
 * Broken Bird: Just about as broken as you can get. Seriously.
 * Bully Hunter: Lucy takes this trope to the logical extreme and beyond in her backstory.
 * But Your Horns are Beautiful: When Kouta first this is more or less what he says.
 * Catgirl: Her appearance looks like this, but the "ears" are actually horns, making her more of a Cute Monster Girl.
 * Clingy Jealous Girl: In the most frightening way imaginable.
 * The Combat Pragmatist
 * Curb Stomp Battle: Pretty much any "fight" she takes part in,  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
 * Dark and Troubled Past
 * Death Glare: And a swift death follows. Always.
 * Defrosting Ice Queen: Most of her arc in the anime. "Defrosting" also includes being slightly less murderous.
 * Depraved Bisexual: Never throughly explained, however if Nyu means anything...
 * The Determinator:
 * Evil Sounds Deep: Lucy's voice is deep and quite ominous in comparison to Nyu's chirpy, childish, high-pitched voice.
 * The Eeyore
 * Fetish Fuel Station Attendant: Deep and ominous voice? Check. Tall, Red and Bishoujo? Check. Woobie? Check. Tsundere and Sugar and Ice Personality? Check. Frequently naked? Check. Badass? Check. Sadistic psychopath? Um...CheckPlease. (It's going to turn someone on, though.)
 * Fiery Redhead
 * Freudian Excuse
 * From Nobody to Nightmare: She was resigned to being bullied by the other children at the orphanage for being a freak of nature. Then she got the power to turn a perfectly ordinary living room into a blender.
 * Hidden Eyes: Quite often, although very prominent when she's just reverted back to Lucy.
 * Humans Are the Real Monsters: Lucy believes strongly this. And considering all she'd been through, one can't honestly blame her (YMMV, of course).
 * Identity Amnesia: The switch between Lucy and Nyu and back is triggered by.
 * Karma Houdini: Averted in the manga; Kouta does not forgive her for,   but  In the anime, however, she is implied to survive her last showdown with the army, and while Kouta doesn't exactly forgive her (or at least not her actions), he's much more sympathetic to her plight, and he'd rather see the killing stop than seek revenge.
 * Kill All Humans: If it wasn't for . She would've done this long ago.
 * Kick the Dog: She once tries to kill Mayu after Mayu saves her from being killed.
 * Kick the Son of a Bitch: The cruel kids at the orphanage.
 * Kick the Morality Pet: Poor ...
 * Limp and Livid: Quite a lot.
 * Long Lost Sibling: In the manga,
 * Love Makes You Evil: At first, but she does get better.
 * 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.
 * Magical Girlfriend: They can't all be Belldandy.
 * 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.
 * Monster Progenitor: She's not the first diclonius by a long shot, but
 * And how can we forget that.
 * Only Known by Their Nickname:
 * Pay Evil Unto Evil: She's far more sadistic towards people who actually deserve it. She'll kill anyone, but she'll torture people like Bando half to death.
 * That doesn't explain what she did to Nana and Manga!Mariko.
 * Then again, it was mostly Revenge by Proxy directed at Kurama, who isn't exactly the nicest guy in the world.
 * Perpetual Frowner: In stark contrast to Nyu. Exception are reserved for when everybody else is unhappy.
 * Person of Mass Destruction: An order of magnitude more dangerous than the other diclonii, due to.
 * She also has the power to destroy the Earth. At the cost of her own life...
 * Power Gives You Larger Horns: A convenient power-up in the manga allowed her to
 * Red Eyes, Take Warning: In the anime. In the manga, they're green according to the cover art.
 * Sanity Slippage
 * Shameless Fanservice Girl: Unlike Nyu, she does know that being naked is a problem, but she often has other things on her mind.
 * Slasher Smile
 * Sociopathic Hero
 * 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.
 * Star-Crossed Lovers
 * The Stoic
 * 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: What young Lucy's tsundere tendencies have matured into by the start of the series. Although not at the same time, Lucy's character seems therefore to be the very rare quartet of Tsundere, Sugar and Ice Personality, Yandere and Cute and Psycho.
 * Super-Powered Evil Side: She's it, except
 * Enemy Within.
 * Sympathetic Murderer: Walking trope Embodiment.
 * Tall, Dark and Bishoujo: She is very beautiful and tall with long red hair, in contrast to Nyu who is neither aloof or tall. If you watch closely, you'll notice that Nyu is actually about a head shorter than Lucy...
 * Then Let Me Be Evil
 * Tragic Villain: So very, very tragic.
 * Tranquil Fury: In the anime, where she kills without a change in her facial expressions.
 * Unstoppable Rage: About 90% of the time.
 * Unusual Ears: Well, they're technically horns(?), but the principle is the same.
 * Used to Be a Sweet Kid
 * 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.
 * When She Smiles: She hardly ever smiles (when she's not killing someone), but when she does...
 * Woman Scorned: Sure, Kouta! Don't tell Lucy that you're going to the festival with your female cousin!
 * Woobie, Destroyer of Worlds
 * You Gotta Have Pink Hair
 * Unusual Ears: Well, they're technically horns(?), but the principle is the same.

Nyu
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,


 * Anything That Moves: Nyu tends to be rather... indiscriminate when it comes to others.
 * Apocalypse Maiden: Nyu is innocent and no threat to anyone. Her other personality is a world-killing weapon.
 * Beware the Nice Ones: Put Nyu in danger or do anything to Kouta, and you are seriously going to regret it.
 * : The anime cuts off before 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.
 * Cute Mute: In the sense that her trauma left her with a very limited vocabulary.
 * Good Eyes, Evil Eyes: Just contrast the innocent Nyu persona's wide, bubbly eyes with the narrow, hateful, tortured eyes of the Lucy persona.
 * Helpless Good Side: In spades.
 * Important Haircut: Nyu's long hair gets chopped off to impersonate Kouta's younger sister Kanae to
 * Innocent Fanservice Girl: Too many incidents to count.
 * Probably the most notable is that she has walked up to Kouta and shoved his hand against her breast, twice, and the 2nd time they were both naked.
 * Pokémon-Speak: Technically, she was nicknamed after the only word she could speak at first. It later becomes subverted after the cutoff from the anime.
 * Shallow Love Interest: Kind of the point.
 * Skinship Grope: She recognizes this behavior as acceptable due to Kouta's mishap.
 * Verbal Tic Name

An 18-year-old student who arrives in the Kanagawa Prefecture to attend college. He is the male protagonist 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
 * Angst Coma: Justified given.
 * Anti-Hero
 * Blue Eyes
 * Dark and Troubled Past: Post Traumatic Stress Disorder, anyone?
 * The Dulcinea Effect: Only slightly, but Kouta is undeniably more inclined to go the extra distance to help out a girl in need.
 * Heroic BSOD
 * Loves My Alter Ego
 * Morality Pet: To Lucy
 * Non Action Nice Guy
 * Star-Crossed Lovers
 * Shiny Midnight Black
 * Team Dad: 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.
 * Trauma-Induced Amnesia: A significant part of the plot.
 * Unlucky Everydude: Very unlucky.
 * Unlucky Everydude: Very unlucky.

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 geniunely 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.


 * Absurdly Youthful Mother: She and Kouta both adopt Mayu despite the fact that Yuka is only 19 and Mayu is 14.
 * Clingy Jealous Girl: In a grating manner as well. People tend to dislike her for this... while forgetting that Lucy can be even clingier. At least Yuka would NOT try to kill Lucy, whereas Lucy HAS used her vectors to push Yuka down and.
 * Cool Big Sis: Arguably. She tries, bless her heart, but it doesn't necessarily work.
 * 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.
 * Misery Poker: Very much so. 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.
 * In the final chapter of the manga,
 * Team Mom: As the older of the girls, she is sometimes referred as the "mother" of the group in the anime.
 * Tsundere
 * Yandere: Early on, definitely, but she fortunately decides to back off.
 * Yandere: Early on, definitely, but she fortunately decides to back off.

A young 14 year-old girl, abandoned by her mother and a victim of sexual abuse by her stepfather. She has run away from home and is homeless at the start of the series, subsisting on bread crusts she is given at a local bakery under the pretence that they are for the small puppy, Wanta, that accompanies her. She ends up living with Kohta and Yuka as her legal guardians. Mayu befriends Nana and tries to take her under her wing.


 * Break the Cutie:  Yes, nary a cutie escapes unbroken in this series.
 * There's also when she hears about Lucy, she doesn't believe that the person she knew as Nyuu could be a sadistic killer and saves her during her 2nd fight with Bandou, after which Lucy tries to kill her.
 * Does Not Like Men / Hates Being Touched: She follows this to a degree;
 * Rape as Drama:
 * The Runaway: A textbook Abused Runaway.
 * Shrinking Violet

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. As a result she has spent her entire life in the Diclonius research facility. 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.

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. In the end,


 * Adaptation Dye Job: Her hair was purplish-blue in the manga, but is purplish-pink in the anime. Also her eyes were green rather than rose-pink.
 * Artificial Limbs
 * Badass
 * Badass Adorable
 * Handicapped Badass
 * Berserk Button: Threaten to hurt her "papa". I dare you.
 * Break the Cutie: An extremely clever inversion. It's explicitly stated that her "Cutie" persona is a psychological defense mechanism that she developed as a result of the universe's constant attempts to break her.
 * Beware the Nice Ones: The few times said cutie-persona/psychological-defense-mechanism is broken through. During Nana & Bandou's first meeting on a moonlit beach, Bandou 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,.
 * Oh, and her fight with Mariko?
 * Can't Catch Up : Despite smarts in battle and ever-increasing savvy, she has a good showing but always gets curbstomped by opponents.
 * Cute Clumsy Girl / Dojikko: Combine with Artificial Limbs that are quite prone to popping out and, well...
 * Detachment Combat / Rocket Punch: Prosthetic limbs plus vectors equals projectile appendages!!! Must be seen to be believed.
 * The Determinator
 * Disability Superpower: See above, plus her prosthesis are naturally Immune to Bullets (as Bando realized during their brief first fight).
 * Hero Antagonist: To Lucy.
 * Incorruptible Pure Pureness: Everything dumped on her only made her sweeter and more heroic, not less.
 * Lethal Chef: Given that she was raised in a lab, this isn't all too surprising.
 * Morality Pet: For Chief Kurama
 * 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.
 * Only a Flesh Wound: Her battle with Lucy.
 * 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.
 * 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.
 * Seven Is Nana: Nana is Diclonius subject Number Seven.
 * Too Incompetent to Operate a Blanket: raised in a lab, and thus, unable to even cut a cabbage with an ordinary knife.
 * Took a Level In Badass
 * You Gotta Have Pink Hair
 * Younger Than They Look: Silpelits age at about double the rate of normal humans. Nana looks 14 and is really around seven years old.

Nozomi
A 15-17 year old girl who's Yuka's best friend and kohai, she aspires to become a famous opera singer. However, her father does not approve of her dream, due to her being the only heir of his business,.

Due to Dad'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.


 * Ascended Extra: She has a special chapter in the manga depicting her past. Arguably the Lightest and Softest chapter in the entire series.
 * Demoted to Extra: Surprisingly few people are aware of Nozomi's existence. Despite being a main character, and the reason the show's called Elfen Lied (it's the name of her favorite song), she was written out of the anime.
 * Potty Failure
 * Pursuing Parental Perils: Nozomi's mother lost her voice from singing due to a vocal cord defect. Nozomi has this same defect and never learns about it.
 * The Runaway: While she didn't really run away in a direct way like Mayu, she still kind of qualifies as an Abused Runaway.
 * Shrinking Violet: With damn good reason.
 * Shrinking Violet: With damn good reason.

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

Kurama was initially respected for his stern, no-nonsense attitude and his devotion to his job, in spite of the horrible atrocities that were being carried out. However, recent events cause Kurama's ironclad devotion to waver...


 * Anti-Hero: Type IV. He's willing to terminate innocent children and not-so-innocent adult women alike, for the sake of saving the human race.
 * The Atoner
 * Badass Bookworm
 * Bishonen
 * Beard of Sorrow: In the later chapters of the manga.
 * One interpretation of the ending of the anime: he actually lasts much longer in the manga. His sanity, however, does not.
 * Fond Memories That Could Have Been:
 * Heroic BSOD: After shooting Mariko.
 * I Did What I Had to Do: He has this attitude as he executes baby diclonius.
 * Offing the Offspring:
 * Pay Evil Unto Evil
 * Red Oni, Blue Oni: Blue to Bando's Red.
 * Scary Shiny Glasses
 * Sensitive Guy and Manly Man: Him and Bando. Though, Kurama is a Badass Bookworm on par with Bando's Badass Normal.
 * Sharp-Dressed Man
 * The Stoic: Initially, although less and less as the plot progresses.
 * The Spock

Voiced by: Joji Nakata (JP), Jason Douglas (EN)
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.


 * Anti-Hero: Type V in the manga. Type IV in the anime. Unlike Kurama, Bando kills mostly For the Evulz, or Revenge.
 * 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. He gets notably less crazy later in the manga, though, as a part of his Character Development.
 * Badass Normal: 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.
 * Big Damn Heroes: Manga exclusive, combined as it often is with a nice case of Dynamic Entry.
 * Blood Knight.
 * Character Development: Bando is probably the most Dynamic Character in the series. He goes from a borderline-Complete Monster who joins the SAT to legally kill people, to a Jerkass who will repay people who are in his debt, to finally, a Jerk with a Heart of Gold and Jerkass Woobie who risks his life to stop the Unknown Man from raping Mayu.
 * The Combat Pragmatist
 * Cool Shades: Very cool.
 * Crazy Prepared: After getting his ass handed to him by Lucy early on.
 * 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.
 * Disability Superpower: His prosthetic arm allowed him to remove a spiked ball from his body during fight with the Unknown Man.
 * The Determinator: 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.
 * Don't Sneak Up On Me Like That
 * Even Evil Has Standards: Bando has lines he won't cross. If he feels in someone's debt he will try to return the favor.
 * And even he can't stand the Unknown Man.
 * Flat What: His expression when is priceless.
 * Hitman with a Heart: Particularly in the manga.
 * Jerkass -> Character Development -> Jerk with a Heart of Gold: While he's a much bigger bastard than normal of the latter, he has his moments . It's perhaps better than nothing that Bandou is simply a Jerkass and not a Complete Monster, given his behavior and the general treatment of most humans in this show!
 * Large Ham
 * Noble Demon
 * Psycho for Hire: Before his Character Development.
 * Red Oni, Blue Oni: Red to Kurama's Blue.

Also known as Number 35, she is a young Silpelit girl. She is regarded as the most powerful of the Diclonius, possessing 33 vectors each with an approximate range of 11 meters 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 and 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. 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: Averted/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.
 * Badass Adorable
 * Curb Stomp Battle: In the Anime, She utterly dominates Lucy!
 * Enfante Terrible: Emphasis on the terrible.
 * Children Are Innocent: ...but she doesn't know better.
 * Evil Cripple: Not so much evil as childishly amoral.
 * 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.
 * Improbable Age: 5 years old.
 * Love Makes You Evil: A lesser extent than Lucy, but most definitely present.
 * Obliviously Evil: For the most part.
 * Stepford Smiler / Slasher Smile
 * Too Powerful to Live: Hence the Explosive Leash.

 * For the Evulz: Has absolutely no reason to kill the puppy aside for his own twisted amusement.
 * Kick the Dog: More like KILL
 * Kids Are Cruel: Of the utter sociopath kind.
 * Karmic Death
 * Oh Crap: Just before Lucy kills him his look is one of pure shock and terror.
 * The Bully: You bet he is!
 * The Sociopath: Oh boy is he...

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 Hidan-level sadist; rapist; heartless; and all-around not very nice. He delights in causing pain and suffering, especially in Diclonius and/or teenage girls. .


 * 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.
 * 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.
 * Ax Crazy: Perhaps the craziest. And considering the likes of Bando and Lucy, that's saying something!
 * Badass Longcoat
 * Complete Monster: THE Complete Monster of the series!
 * Dirty Coward: He gleefully tortures and rapes defenseless Diclonii and normal children, but runs away when he confronts Bando.
 * Eviler Than Thou: definitely worse than Bandou and/or Lucy, and arguably worse than even Kakuzawa Sr.
 * Expy: Of Alucard. In both looks and personality (Minus the Dirty Coward part).
 * Fan Nickname: For note, the above name is a fan term given to him. He never speaks his name, nor does anyone know his name.
 * Laser-Guided Karma: Shortly after he tries to rape Mayu, Bandou comes in kicks his ass.
 * Nice Hat: In tune with his "Alucard wanna-be" appereance.
 * No Name Given: This arguably just makes him worse.
 * Psycho for Hire: Less Hammy than Bando, but much more sadistic.
 * Rape as Drama: Does this to Number 28, and tries (and comes terrifyingly close) to do it to Mayu (And probably would've done the same to Nana).
 * It's also implied that he was allowed to rape many more Silpelits by the staff of the facility.
 * The Sociopath
 * Sunglasses At Night
 * Lennon Specs
 * Lennon Specs

Number 28
A relatively minor manga-only character, 28 is mainly known for the absolutely nauseatingly horrifying fate she suffers at the hands of the Unknown Man.


 * And I Must Scream / Fate Worse Than Death / Cruel and Unusual Death: Sweet mother of God... she has everything below her torso removed.
 * Rape as Drama: Courtesy of the Unknown Man.
 * The Voiceless: She doesn't get any spoken lines during her time as a whole person,
