    Semyon "Simon" Brezhnev
Voiced by: Takaya Kuroda (JP), Patrick Seitz (EN)

A black, Russian sushi hawker. Being an immigrant, his Japanese isn't very good and his physical appearance frightens some people. Despite this, he's a kind and intelligent man who only wants customers to visit the restaurant.

Affiliated with the Dollars.

  • The Atoner: He isn't very pleased with what he did back in his home country and just wants to live a peaceful life in Ikebukuro.
  • Anime Accent Absence: Averted, but in the wrong way. His accent sounds like an English speaker's, not a Russian's.
  • Badass Pacifist: Aside from one memorable incident in which he gave Izaya a black eye, he's one of the most non-violent people in the entire show.
  • Dark and Troubled Past: Was in the KGB until the Soviet Union fell, after which he (along with Dennis, the future owner of the Russian Sushi shop he now works at) took a job under Russian weapons dealer Drakon. What exactly he's done under Drakon's orders is vague, but it obviously wasn't good.
  • Eloquent in My Native Tongue: He's deep, eloquent, witty and philosophical (as evident from his inner monologues), but it's hardly visible behind his intimidating appearance and broken Japanese.
  • Face of a Thug: Simon is friendly as all hell, but the fact that he's both a Scary Black Man and a Husky Russkie tends to scare people away.
  • Famous-Named Foreigner: Brezhnev, while not terribly rare, is still a rather uncommon surname in Russia, and will immediately invoke the late Leonid Brezhnev and The '70s.
  • Former Regime Personnel: He and Dennis were former KGB, and true to stereotype, transitioned from that into involvement with The Mafiya.
  • Funny Foreigner: A black Russian with broken Japanese is comical if you're not scared of him. It's heavily implied he is just be playing this for what it's worth.
  • Gentle Giant: He towers over most Japanese people and intimidates them. It must be the power of the Gaijin Smash.
  • Hidden Depths: He may look like a large, dumb guy, but he really hides years of deadly skills back in his home country.
  • Husky Russkie: His large stature is part of why he has trouble getting customers.
  • It's Raining Men: He leaps down from the seventh floor of an apartment building and, of course, lands safely.
  • I Was Just Passing Through: He says that the aforementioned leaping off the building was only because he was making a delivery to a client on the top floor when he saw the fight.
  • Made of Iron: Simon is strong and/or skilled enough to almost match Shizuo in a fight, but still walks away worse for wear with some bruises. We don't know if he could actually beat Shizuo if he tried (see Martial Pacifist below), but going toe-to-toe with Shizuo for a sustained period of time and not getting seriously injured is very impressive.
  • The Mafiya: Simon and Dennis (now Chief Chef) are former members of such an organization.
  • Martial Pacifist: Simon doesn't even like talking about violence, and only uses his martial arts skills to either defend himself or break up a fight. He has, however, killed someone in the past.
  • Mother Russia Makes You Strong: He can throw one hell of a punch if he has to.
  • Obfuscating Stupidity: He puts up a very friendly front to lure in customers and make them feel at home, but when things go too far, he'll deride the perpetrator in Russian. Also, his Japanese is so bad that some characters wonder if he's secretly a competent speaker.
  • Retired Badass: Ex-KGB and Spetsnaz before the end of the Cold War.
  • Running Gag: His apparent inability to bring customers to his shop.
  • Scary Black Man: Simon's career as a sushi tout seems to suffer as a result because both his size and his skin tone scare the native Japanese.
  • Static Character: Although we learn more about him, Simon himself doesn't change during the anime.
  • Super Strength: Simon jumps from a building and manages to stop Shizuo's rampage. From the reaction everyone involved give, this evidently happens a lot.
  • Tastes Like Friendship: He espouses the belief that the only reason people fight is because they are hungry. Thus, after breaking up a fight he makes the opponents eat together.
  • "The Reason You Suck" Speech: Punches Izaya in the face and gives him one in Russian. The point of it was Simon claims Izaya manipulates people to kill each other but has never done it himself and claims higher moral standing for this. He also warns Izaya not to manipulate people to kill each other again, as it feels terrible.
  • Wham Line: Starts of his "Reason You Suck" Speech to Izaya with one.
    Simon: Have you ever killed people? I have.
  • You No Take Candle: Outside of his Inner Monologue, he speaks exclusively in the casual register, overuses the sentence-enders yo (emphasis) and ne (seeking confirmation a la ", yes?") and rarely if ever uses any particles, amounting to a Japanese variant of this trope.


The owner of Russia Sushi in Ikebukuro as well as Simon's employer and old colleague back in the Soviet KGB.

    Kyohei Kadota
The muscle of The Dollars.
Voiced by: Yuuichi Nakamura (JP), Steve Blum (EN)

"If you guys do decide that we're your enemy... if you want a fight, you'll get one."

Leader of a pretty small-time gang consisting of himself, Erika, Walker, and Saburo. Also works as a tile layer.

Formerly affiliated with the defunct Blue Squares, now affiliated with the Dollars.

  • Alliterative Name: Kyohei Kadota.
  • Anti-Hero: Despite being a gang leader, none of his actions are villainous, or at least have villainous intentions. In fact, he left his former gang because they wanted him to do things For the Evulz. Despite being part of a gang Kadota is basically The Cape.
  • Badass Normal: One of the best, if not the best fighter in the cast aside from Shizuo, and he's just a normal guy with a van.

    Erika Karisawa and Walker Yumasaki
The shameless otakus of Ikebukuro.
Erika is voiced by: Ayahi Takagaki (JP), Mela Lee (EN)
Walker is voiced by: Yūki Kaji (JP), Brian Beacock (EN)

Erika: A great man once said that the world is a myth. I think he said it, anyway. Even if he didn't, I'm sure someone else said something similar.
Walker: A great man once said that the world is symbolic. I think he said it, anyway. Even if he didn't, I'm sure someone else said something similar.

A pair of hardcore otakus who hang around with Kyohei and Saburo. There is more to them than meets the eye.

Both affiliates of the Dollars, by proxy of Kadota.

  • Cloudcuckoolanders: They both launch into a rather extensive conversation in episode 20 where they characterize Chief Chef of Russian Sushi as a character in a cooking manga, and invent a backstory involving him serving with the Red Army and fighting The Mafiya. Which, of course, is distressingly on the mark.
  • Commonality Connection: They're both crazy Otakus with a penchant for "manga-based" torture methods. This is probably the reason why they're as close to each other as they are.
  • Crack Pairing: Not one themselves, but they're certainly not adverse to shipping them in-universe.
    Erika: Which one is better — Fans/Trolls or Trolls/Fans?
    Walker: Are we assuming that's yaoi or yuri? That's important. Very important!
  • Cute and Psycho: They enjoy manga, anime, hentai, torture, and bloodshed. Thankfully, Kyohei reigns them in pretty well.
  • Defector from Decadence: Like Kadota, they both left the Blue Squares.
  • Even Evil Has Standards: Both dropped out of the Blue Squares along with Kadota because they felt that the group went way overboard with beating up a young woman.
  • Expy: Walker and Erika have a lot of similarities, both in character and plot facilitation, to their Baccano! predecessors Isaac and Miria.
  • Eye Scream: They were going to brand the eyeballs of one of the thugs they caught that work for Yagiri pharmacy.
  • Heroic Comedic Sociopaths: Both Walker and Erika have very few qualms about doing anything with their characteristic cheerful nonchalance. They've just figured that being nice is more fun and less trouble.
  • Let's Get Dangerous!: When they decide to get serious, these two can get surprisingly violent.
  • Medium Awareness: Both Walker and Erika have said things that suggest they know they're in a Light Novel.
  • Meta Guys: They constantly reference anime, manga, and light novels up to the point that they associate real life happenings with certain tropes.
  • My Master, Right or Wrong: Subverted. Walker and Erika have vowed to follow Kadota no matter how many people they have to stab, torture, or firebomb. Of course, Kadota never asks them to do this stuff, and has to veto (most of) their more sociopathic ideas.
  • Noodle Implements: "I don't care what you do to him. Just don't use gasoline inside the car like you did that last time."
  • Obfuscating Stupidity: They may seem like two otaku, but don't be fooled... they're dangerously efficient.
  • One-Hour Work Week: As it turns out, Walker and Erika do have jobs — they're an ice sculptor and a jewelry maker, respectively. They just have really flexible schedules due to being freelance.
  • Otaku: Big anime/manga otaku who don't really distinguish between fiction and reality; in fact, they fit the negative stereotype that otaku are psychotic, although they're still basically "the good guys".
  • Platonic Life-Partners: Despite how close they are, they never display any romantic interest for each other.
  • Shipper on Deck: Erika's Shizuo/Izaya shipping aside, Walker once wrote Celty/Shinra fanfic. They both ship each other with Kadota.
  • Sleep Cute: After falling asleep next to Masaomi's hospital bed.
  • Strange Minds Think Alike: As demonstrated when both came to the conclusion that Anri was a Flame Haze at the exact same time, despite being separated.
  • Those Two Guys: Subverted. They appear to be just a pair of Otaku hanging around with Kyohei and Saburo, but they're just as involved in the Mob Wars as everyone else is.
  • Torture Technicians: They enjoy torturing people for information using methods from manga and novels. Case in point: that guy they wanted to interrogate at the end of episode 6, they were going to brand his eyeballs with solder, and can be seen explaining/acting out how the "procedure" will go right in front of him in graphic detail.
  • True Companions: Their relationship with Kadota, Togusa and each other.
  • Undying Loyalty: To Kadota, and both have made it clear they would do anything he asked without question.



  • Beware the Nice Ones: Don't make Walker angry. You may get yourself stabbed in the hand with a pair of chopsticks. Or set on fire.
  • Bishōnen: The novels describe him and Erika as being good looking enough to be models, if not for their Otaku tendencies.
  • But Not Too Foreign: It's regularly implied in the Light Novels that Walker is biracial, probably with American or European ancestry.
  • Daydream Believer: Walker's a certifiable Otakin.
  • Eyes Always Shut: He does open them briefly when he's planning to do something especially devious (like in episode 18 when he sets some Blue Squares on fire), revealing that he possesses gold eyes. Lampshaded here:
    Walker: I'd glare at you, but they're closed!
  • Gratuitous English: His name, though the books regularly imply that he's probably biracial.
  • Hypocritical Humor: Walker may rag on Erika for her excessive Yaoi Fangirl tendencies (particularly her tendency to write her friends into elaborate slash fantasies) but, slash aside, he's just as bad (he once wrote a Kadota/Erika BDSM fic).
    Walker: Wait, Karisawa-san, please stop! Why are you fantasizing about Kadota-san and me in a Boys Love relationship!? I've said over and over that people like Karisawa-san are the reason the society has a negative impression of otaku culture in general! I say Kadota-san and I should become heroes in Galgames who win over the hearts of loads and loads of heroines! Actually, we can even do without Kadota-san! I'll be happy as long as I have this bondaged right hand blessed with the power of ancient moe-moe peoples so that every girl who sees my right hand would go 'Woo ~'...
  • In the Hood: He wears a light blue hoodie.
  • Kill It with Fire: His preferred weapon of choice are molotovs and lighters. He even has a makeshift flamethrower made from a fire extinguisher. Walker sets the Blue Squares leader's van on fire with one when he and the rest of the gang rescue Saki.
  • Multi-Ethnic Name: His given name is English, his surname is Japanese.
  • My Greatest Failure: Walker once published a doujin novel sometime ago. He is not happy with it at all. Erika however loves to tease him about it.

    Saburo Togusa
Voiced by: Takuma Terashima (JP), Spike Spencer (EN)

The fourth member of Kyohei's gang, as well as the gang's official driver. Affiliated with the Dollars, by proxy of Kadota.

  • Angrish: Mutters to himself incoherently over Walker and Erika's choice of replacement door for his van. When they ask if he's OK, he bellows at them to shut up.
  • Badass Driver: He always drives the van and he handles it well.
  • Berserk Button: Do not threaten his van, his friends, or his favorite Idol Singer.
  • Big Damn Heroes: In episode 24, alongside Kadota.
  • Butt-Monkey: Wonders why he has this status when Shizuo tears off the side door of his van to use as a weapon.
  • Calling Your Attacks: "Turning LEFT!"
  • Car Fu: Uses his van to fight troublemakers by ramming into them.
  • Cool Car: He really puts that van into good use. Even after having the door replaced with anime characters painted on it, he still makes it work.
  • Defector from Decadence: He's also a former member of the Blue Squares, who left alongside Kadota, after being disgusted by their amoral activities.
  • Drives Like Crazy: When he's particularly pissed he indulges in somewhat maniacal driving. Or even when he's not particularly pissed. Case in point: driving down stairs.
  • The Generic Guy: To everyone else outside of Kyohei's gang. He doesn't exactly leave a lasting impression on anyone. Celty had to be reminded what his name is.
  • Heroic BSoD: Seeing Shizuo tear off a door of his van briefly sent him into shock.
  • Only Sane Man: Subverted. He may look like this in comparison to Erica and Walker, but when Ruri-chan comes up he proves that he's every bit the otaku they are, and when Kadota gets hit by a car, he's as ready to get violent as Walker.
  • Otaku: Unlike Walker and Erika, the object(s) of his obsession are Idol Singer Ruri Hijiribe and his Toyota Tarago.
  • Pay Evil unto Evil: With a bit of Laser-Guided Karma. When Kadota identifies Nasujima as the one who ran him over and caused his coma, Saburo runs him over in turn after his final attempt in seizing power fails, and hands him to Haruna.
  • Tranquil Fury: After Kadota gets put in a coma by a hit-and-run, he's superficially calm even when threatening people with the What a Drag treatment if he finds out they're responsible.

    Namie Yagiri
Voiced by: Sanae Kobayashi (JP), Bridget Hoffman (EN)

Chief of the 6th lab of Yagiri Pharmaceuticals and older sister of Seiji Yagiri — with whom she has a rather disturbing romantic attachment to. This has repercussions later on when she tries to capture Mikado in order to get a hold of Mika Harima, resulting in the first-ever Dollars meeting and Yagiri Pharmaceuticals' shady business involving kidnapped people being used for medical experiments being exposed, which in turn leads to Yagiri Pharmaceuticals being completely absorbed by the American company Nebula, and her out of a job, at least until Izaya offers her one...

  • Adaptation Dye-Job: Brown eyes in the anime and manga, navy in the novels. Both match the curtains.
  • Aloof Dark-Haired Girl: Almost always described as this in the novels. She's tall, has long dark hair, and displays an extremely aloof and cold attitude towards anyone who isn't her brother. She's also quite attractive, even Izaya thinks she's foxy.
  • Big Bad Wannabe: At the time of her introduction, we were led to assume that she was going to be the main villain, but she quickly gets shown up by Mikado, of all people, and to top it all off, she's now nothing more than a pawn for the real Big Bad, Izaya.
  • Big Brother Attraction: Inverted since she's the older sibling, but she makes no effort in hiding her disturbing affections for her brother.
  • Broken Ace: She's always described as an incredibly stunning young woman and she has enough smarts to give Izaya a run for his money. She's also rich, as well as the head of Yagiri pharmaceuticals. Oh, and did we mention she's a virtually emotionless Jerkass who's madly in love with her brother?
  • Brother–Sister Incest: Onesided, but her affection for her brother is clearly not platonic. This obsession results in her effectively throwing her father's company away, all to try and keep Seiji close to her.
  • Clingy Jealous Girl:
    • More jealous than clingy. While she makes it a point to drape herself every time she sees Seiji, she doesn't stalk him or go out of her way to see him so much anymore. She just complains about Mika and gushes over Seiji via words.
    • She shows the extent of her clinginess in season 3. Not only does she break a teacup when she hears Seiji is using the First-Name Basis with Mika, she actually tries to kill Mika once she starts to consider her a real "rival" for Seiji's affections.
  • Deadpan Snarker: When she's not lusting after her brother, that is.
  • Decoy Antagonist: She's initially set up as the Big Bad, but it quickly turns out that's not so; Izaya surpasses her by far.
  • Demoted to Extra: Went from heading R&D at a chemical corporation to stirring soup and serving tea for Izaya.
  • Disproportionate Retribution: After getting humiliated by Mikado, she later tells Horada that he's the leader of Dollars in the hopes that Mikado will be killed by him. Lampshaded by Izaya, who says vindictive people like her are scary.
  • Girl with Psycho Weapon: Often depicted with a cleaver or a hacksaw in official art.
  • Hypocrite:
    • She likes to rub Izaya's nose in his lack of friends. But while he possesses at least one friend, she doesn't have any. Possibly a subversion seeing as she doesn't seem to want any friends.
    • Her limelight episode starts off with her going on about how fake people are. She believes that people don't love, but just want to be needed and only take but never give. She swears that her love for her brother is different, despite that he only calls her when he needs money or to get him out of a bad situation. He isn't even affectionate to her. Their relationship is a prime example of the "fake love" she looks down upon.
  • Insane Troll Logic: Listen to her monologue about her "pure" love of her brother. It must run in the family.
  • Jerkass: A slightly subtle version, but Namie doesn't really give a rat's ass about anyone but her brother. She's also not particularly fond of teenagers, and she's constantly insulting Celty, Mika, and Izaya, but you probably won't feel bad for the latter.
  • Knight Templar Big Brother: She'll do anything to keep Seiji safe and happy. Even cover up attempted murder and forcing a teenage girl to get plastic surgery to resemble his sick crush.
  • Lack of Empathy: Being told that she's an awful person for all of the human experiments she's been doing really doesn't faze her at all. If it doesn't hurt Seiji, then she simply doesn't care. However she is aware of empathy, making sympathetic statements about Celty's separation from her head and disturbed comments about her employers immoral actions.
  • Large Ham: Normally not, but when going up against Mika in season 2, she slips into Evil Is Hammy mode a few times.
  • Like an Old Married Couple: Appears to live in Izaya's apartment, and often cooks his meals for him. Although she frequently complains about him and tries to annoy him all the time, she probably knows him better than anyone else (and vice versa).
  • Love Makes You Evil: There is nothing she won't do for Seiji's sake.
  • Mad Love: Her relationship with her brother is one of the most disturbing in the series, and that's saying something.
  • Ms. Fanservice: Moreso in the manga, where she's shown naked in the shower for about three pages. Granted, she's bathing her brother, so...
  • Murder the Hypotenuse: Many of the experiments she conducted on Celty's head in the lab involved her trying to destroy it somehow, although the head would undermine her efforts by regenerating from any injuries it sustained. Also, she later attempted to kill Mika in the third season, although she was thwarted.
  • Non-Action Snarker: There are several action girls in Durarara!! but Namie isn't exactly one of them. Until Season Three (or Season Two of 2X) that is, when she kicks Mika's butt in an abandoned warehouse and almost kills her. Luckily for Mika, Seiji intervenes.
  • No Sense of Personal Space: Once again, to her brother, who she pretty much drapes herself around every chance she gets. If he still lived in the same house as her, she would still be taking baths with him. (That last part was only in the manga.)
  • Ojou: She's the heiress of the highly successful Yagiri Pharmaceuticals, and had become the CEO of the company by the start of the story. Unfortunately, it didn't last.
  • Oral Fixation: Yasuda Suzuhito, the illustrator of the original novel, seems fond of depicting her with something in her mouth.
  • Parental Neglect: Likely the main cause of her... erm, "pure" love for Seiji. It's a little more elaborated on in the novels and the manga than it was in the anime.
  • Promotion to Parent: After their parents lost their jobs, she was expected to take care of her little brother while they argued about what to do. Which she did, happily.
  • Sassy Secretary: Izaya hires her as his personal assistant after the whole fiasco with Yagiri Pharmaceuticals. Much snark is tossed around between them.
  • Servile Snarker: She would dutifully complete her tasks as Izaya's secretary. But not without finding her own ways to insult and/or irritate him along the way.
  • Sexy Secretary: She becomes Izaya's secretary and he calls her foxy.
  • She's Got Legs: Oh, yes. Her stockinged legs are proudly displayed in any art piece that she's included in. Sometimes, Suzuhito just draws her legs.
  • Single-Target Sexuality: Disturbingly Seiji-sexual.
  • Smug Snake: Up until she was shown up by Mikado, she's very sure of herself despite the fact that she fails so often.
  • Snark-to-Snark Combat: With Izaya on occasion, though he isn't really snarky with anyone else.
  • Stalker with a Crush: She pays Izaya's sisters unbelievable amount of money to spy on Seiji on her behalf.
  • The Stoic: Normally bears a stern expression (unless Seiji is involved).
  • Sugar-and-Ice Personality: She's generally quite icy, especially in comparison to Izaya, but melts into a puddle of warm, bubbly water when Seiji's around. The manga takes it Up to Eleven.
  • Supreme Chef: She gets a 95% rating for her cooking skills.
  • "Take That!" Kiss: She steals a kiss from Mika right before trying to disfigure Mika's face with chemicals.
  • Those Two Bad Guys: When teaming with Izaya. Particularly evident in the Akane arc.
  • Villainous Breakdown: She has quite the breakdown when The Dollars gang up on her and her goons .
    • In Ketsu, she completely snaps and starts spilling out personal information for the goal of getting Mikado to move.
  • Villainous Incest: Let's just say her feelings for her brother are creepy and disturbing and leave it at that.
  • Volleying Insults: Her interactions with Izaya tend to subtly fall under this in recent volumes, though usually it's just her threatening to kill him and him taunting her.
    Izaya: I've already had you working on everything that needs to be worked on at this point! Ahh, how boring.
    Namie: ......May I beat you up?
    Izaya: No. What's the matter, am I not paying you a pretty decent salary? I don't think beating up your head man would be a good idea.
    Namie: In that case, I'm going to beat you up once I receive my salary.
  • Yandere: She will do anything for her dear Seiji. She was willing to hide the fact that Mika was almost killed by her brother and get rid of Mikado because he knew too much. In the manga, she tried to destroy Celty's head when Seiji told her he liked it. Later, she tried to get rid of Mika when she decided she was a threat.
  • Zettai Ryouiki: Type A; novel only. Her thigh-highs are often drawn with tears in them, for extra sexy.

    Seiji Yagiri
Voiced by: Kazuma Horie (JP), David Vincent (EN)

The above mentioned's younger brother. Dropped out of high school on the first day to be with his lover. He has now returned and is now Mika Harima's boyfriend until he retrieves Celty's head once more.

  • A Day in the Limelight: After being Demoted to Extra. Episode two of the second cour of the second season along with Mika and Namie. Also episode one of the third cour along with Celty's guild.
  • All Take and No Give: His sister would do anything for him (except giving him Celty's head) in order to keep him safe and happy. Seiji knows this, using her to get money or get him out of a bad situation and not even bothering to thank her properly in return.
  • Apologises a Lot: To Mikado because of the Dollars incident in the first season and to Mika for thinking she and Anri don´t talk very much now because of him.
  • The Atoner: By the end of the first half of the first season, he wanted to redeem himself after knowing that he fought with almost every character for someone who wasn’t his love.
  • Batter Up!: He does this to Mika in the manga, after she breaks into his apartment room through the window.
  • Broken Ace: He's handsome, smart... and a huge Yandere for a ghost's severed head.
  • Character Development: By the beginning of the second season, he learned to be not so reckless and acting without thinking before. He also began treating Mika as a person and not just as a girl with the face of the head he loves.
  • Commuting on a Bus: After Seiji began dating Mika, apart from little scenes they don’t hit hard in the plot like in the beginning. Justified in the second cour of the second season when it is revealed that her girlfriend was keeping him out of every plot in the series in order to not being put in danger.
  • Constantly Curious: He claims the reason he gets into so many problems is not because he is a good person (like Mika said) but because he just has a curious personality.
  • Dating Catwoman: He saw his relationship with Mika like this at first: saying he would date the person who made his life a living hell, as a punishment to all the troubles he had caused to the other characters.
  • Devoted to You: Both Namie and Mika are crazy about him. However, he's only interested in Celty's head.
  • Empty Eyes: He has blank, dull eyes at all times.
  • Even Evil Has Standards: Having no problem in attempting to kill a girl if that means protect his love, but in the novel he showed clear disgust to Yagiri Pharmaceuticals and its experiments with humans, claiming that these guys don’t respect the lives of others.
  • Exhausted Eye Bags: He seems to have a constant stare with lines under his eyes, as if he can barely sleep.
  • Fanboy: To Kasuka and his films, also he has no problem in stating he is a hot guy. He claims being a fan to Ruri’s make-up skills too.
  • Flat Character: There is nothing to him beyond being a Yandere who has two other Yanderes attracted to him. That's it. However this is averted in the light novels where he let see some of his Hidden Depths, but such caracteristics were not shown in the anime adaptation.
  • Go Mad from the Isolation: Just like his sister, since their uncle was never in the house; the first thing that made Seiji feel something was when he interacted with the head.
  • Heroic BSoD: How he reacted after knowing Mika’s reveal.
  • Hyper-Awareness: As a part of his Character Development, he began paying more attention to his surroundings and other people behaviors: how he reacted in front of Mika, Mikado and Akabayashi are good examples of this.
  • Irony: Gives Mikado some constructive advice concerning his love life in the anime.
  • I Will Find You: Even in the end of the series, he never stopped searching for the head.
  • Love at First Sight: Seiji's been in love with Celty's head the moment his sister snuck him in to see it.
  • A Love to Dismember: Dude fell in love with a head. It's like he's competing with Shinra for the title "Lover of the Uniquely Beautiful." Which makes it more funny since technically they are not competing despite being in love with the same woman.
  • Loving a Shadow: Seiji decides to stay with Mika after she confesses that she's not really Celty's head — not because he actually likes her, but because she's a close enough substitute until he can get his hands on the real thing again.
  • Mad Love: His relationship with Mika definitely counts, since he not only tried to kill her once, but even after he agreed to stay in a relationship with her, he outright states he is only using her until he can find the real head of his beloved Celty again.
    Seiji: I'm in love with the scars on your neck...
  • Morality Pet: Is one for his sister. Namie will drop anything and follow whatever Seiji suggests.
  • Nerves of Steel: Unless it has something to do with Celty's head, absolutely nothing phases Seiji.
  • Nightmare Fetishist: Besides being in love with a girl's severed head, he loves horror movies because seeing monsters reminds him of Celty's head.
  • Older Than They Look: He is described as not having any boyish features on his face, and looking like he is in his twenties.
  • The Pen Is Mightier: Does this to Shizuo, who is more amused though than actually pissed off.
  • Pet the Dog: He thanked Mika for how much she cares for him. In the finale he claimed he ended up seeing her as a family even though he still affirmed he doesn’t love her.
  • The Power of Love: Part of his Yandere traits in the first season was always stating that love is what made him “invincible”.
  • Rule of Empathy: The reason why he loves Celty's head, he just want to free her and to not suffer the same isolation he had to get through.
  • Savvy Guy, Energetic Girl: He and Mika share this trait most of the time. However they seem to change roles when they confront someone: while Mika becomes more level-headed and crafty; Seiji behaves like a hot blooded person who prefers following his instincts.
  • Selective Obliviousness: He's in love with a severed head named Celty, and doesn't comment on the headless body named Celty running around. He has been shown to be more aware of things than people expect, so it's likely he's in the same situation as Shinra, only caring about one half of Celty and ignoring the other half.
  • Shipper on Deck: He and Shizuo are the only characters who ship Kazuka and Ruri.
  • Sickeningly Sweethearts: He and his girlfriend are always seen cuddling and acting lovey-dovey. They are actually a subversion, since their relationship is extremely disturbing.
  • Single-Target Sexuality: Ever since he was a child, he has made clear he loves no one besides Celty's head.
  • The Sociopath: It's pretty clear he only cares about himself and Celty's head. What does he do after he smashes his stalker's head into a wall for seeing Celty's head? He calmly calls his sister to have her take care of it and sits to eat cup noodles. The only thing that bothers him is that Celty's head would be taken away from him.
  • "Take That!" Kiss: Gives one to Namie for stealing a kiss from Mika and trying to kill her. Needless to say, it has the exact opposite effect from what he intended.
  • Tall, Dark, and Handsome: Just enough so that when Kida meets him just before he drops out of school, he suggests that he join him and Mikado in picking up girls.
  • Yandere: Puts three pens in Shizuo for looking at Mika Harima wrong. Strangely enough, it was Celty who grabbed her, not him, then he tries to stab Mikado with a scalpel. And earlier than that he grabbed Mika by the hair and smashed her face into a wall just because she caught sight of Celty's head (which he had stolen from his sister's lab), resulting in Mika having a facial reconstruction which resulted in her face looking like Celty's as part of a ploy by Namie to keep Seiji under her control.
  • You Know Too Much: His reason for trying to kill Mika after she sees Celty's head in his room.

    Mika Harima
Voiced by: Mariya Ise (JP), Carrie Savage (season 1), Kira Buckland (season 2) (EN)

Seiji's girlfriend. At first believed to be Celty's missing head in a new body, she is later revealed to be Mika Harima given plastic surgery to have Celty's face and make Seiji like her.

  • Accomplice by Inaction: Right after she confessed Namie that she had been stalking everyone in the series she scolded her saying that a lot of conflicts surrounding her friends would have been resolved if she had decided to intervene, and while Mika agreed with that, she stated that keeping Seiji safe is the most important to her... even so, she wasn't entirely happy with taking that decision.
  • Adaptation Dye-Job: The first novel describes Celty's hair as "as black as darkness itself".
  • A Day in the Limelight: Episode two of the second cour of the second season along with Seiji and Namie. Also episode one of the third cour along with Celty's guild.
  • All Girls Want Bad Boys: Even after Seiji tried to kill her and explicitly told her he would murder her if she tries to eat Celty's head, Mika is still madly in love with him.
  • Broken Ace: Pretty (even before the surgery), popular, intelligent, athletic, good with computers and electronic devices… to bad she only uses her skills to stalk everyone related to her boyfriend in order to protect him.
  • Chekhov's Gunman: Shows up in the opening theme, unnamed. Anyone who saw Baccano!'s opener (and the conspicuously unnamed Claire Stanfield) knows she's important.
  • Chekhov's Skill: Thanks to the information she managed to gather, she could prevent Seiji to be kidnapped by his uncle Seitaro and Kujiragi Kasane.
  • Clingy Jealous Girl: She hides it very well, but in season 3 she reveals her gruesome plans for Celty's head if she ever gets her hands on it.
  • Commuting on a Bus: She and Seiji hardly intervene in the plot by the end of the first half of the first season and the first part of the second one… Justified in the second part when Mika reveals that she is aware of every plot that the characters are involved and deliberately avoid them in order to not put Seiji and herself in danger, to enjoy the peaceful life of keep being secondary characters. However due to Seiji’s uncle becoming one of the Big Bad of the second season, both of them along with Namie get the spotlight again.
  • Curtains Match the Window: Before she had the surgery to make her head look like Celty's.
  • Ditzy Genius: Mika is an academic genius who gets straight As in all of her classes. She could have gone to a prestigious high school if she wanted to, but chose Raira Academy instead to be with her friend and foil, Anri.
  • Face Death with Dignity: When Namie was about to put acid on her face, Mika thought about blowing the liquid towards her... before realizing that she wouldn't hurt any of her boyfriend's relatives, so she simply closed her eyes.
  • The Fake Cutie: She seems super sweet and adorable... but then we find out what she's really like.
  • Faking Amnesia: She claims that she doesn't have any memory of who she is. She's lying, of course. Namie was actually planning on really giving Mika amnesia after the plastic surgery was finished, namely by removing her memories about Seiji and Celty's head, although Mika manages to escape before she can carry it out.
  • Foil: To Anri. Both girls are aware of how opposite they are to one of another. Doesn't stop them from being "friends", so to speak.
  • Foreshadowing: The first opening, which names off all the major players, leaves Mika completely nameless. Naturally she's at the center of the big twist regarding Celty's head.
  • Gambit Pileup: Downplayed with Izaya. He was one of the people victim of Mika’s surveillance, but Izaya managed to find all her devices… too bad Mika also taped the people he kept in touch so she still was aware of his plans.
  • Girl with Psycho Weapon: Hers is a trowel, and she's not afraid to use it.
  • Hidden Depths: Despite her primary character relationships are with Anri and Seiji (and through him, Namie), formerly, she's more developed than Seiji is.
  • Hidden Wire: She uses tiny listening devices and cameras to keep track of the people she stalks.
  • I'm a Humanitarian: She is planning to eat Celty's head if she ever finds it.
  • Improbable Weapon User: At one point, she picks up a mop and begins bashing the heads of a Girl Posse with it. She also carries around a trowel.
  • In Love with Love: As long as Seiji let her love him, she doesn't mind if her love is no required. Also Anri claimed that, before ending up with Seiji, she was always finding her “true love” in different guys.
    What she loved the most, was being in love with somebody.
    This meant she didn't really think about the circumstances of her partner.
    For the sake of her own passion, she could easily sneak into the house of her partner, and would even consider setting up bugs in the room of her dearly beloved.
  • Le Parkour: She claims she gained good reflexes and athletic skills due to always climbing walls and ceilings of the people's houses and apartments she wants to stalk.
  • Mad Love: With Seiji. Even getting brained by him won't stop her from agreeing to illegal plastic surgery so she can hook up with him.
  • Magic Plastic Surgery: She got plastic surgery to look like Celty's head.
  • Master of Unlocking: She managed to pick a lock to a new door in seconds.
  • Ms. Exposition: Just when she was about to lose against Namie, she decided to tell her every piece of information she has about the majority of the cast, along with important plot points, past plot twists and relationships between characters that even the viewers didn’t know. Such reveal serves as a good Recap for the viewers to keep track of the many subplots in the series.
  • Murder the Hypotenuse: Mika has... plans for Celty's real head if she ever gets her hands on it.
  • Nice Hat: She wears a cute white hat adorned with a heart nearly all the time.
  • Non-Answer: Every time Seiji asks her why she is in love with him, she only says "Because you are you". Inverted in one time when, after Seiji asked her the same question again, Mika replied:
    Mika: "I'll tell you why I love you if you pretend to love me at least"
    Seiji: "as a friend?"
    Mika: "as a lover"
  • Obfuscating Disability: Pretends to be mute at first.
  • Obfuscating Stupidity: This girl knows everything that's going on: Mikado being the leader/founder of the Dollars, Izaya being stabbed, what Celty is looking for, who's who on Izaya's chat, Anri hosting Saika inside her, etc. She knows it all, and more. All because she has tapped everything and everyone relevant in the story due to the fact that they are all connected to her love, who she wants to keep safe. The only reason she hasn't revealed all that information to her friends is because Seiji might find out and intervene, getting himself hurt or killed in the process. Now digest that for a second, and then realize she might have more information than Izaya. Thank you.
  • Older Than They Look: While it's obvious that she looked older after getting her face chaged, she was described as looking rather mature for her age... until she began talking.
  • Playful Hacker: Learns how to hack computers to develop even further her stalking traits Thanks to this, she is even aware of the identities of every people in the chatroom
  • Red Herring: The visible scar around her neck is designed to deliberately throw off both characters in-universe and viewers who are not already in the know about the location of Celty's head.
  • Replacement Goldfish: Once Seiji finds out she's not Celty's head, he lets her stay with him anyway since she's the closest thing he has to Celty's head until he finds the real one.
  • Savvy Guy, Energetic Girl: She and Seiji share this trait most of the time. However they seem to change roles when they confront someone: while Mika becomes more level-headed and crafty; Seiji behaves like a hot blooded person who prefers following his instincts.
  • Scars Are Forever: Has a large, jagged scar running around her entire neck. This was part of her plastic surgery in order to fake having a new head.
  • Shipper on Deck: She supports Mikado/Anri and is interested in the progress of their relationship.
  • Sickeningly Sweethearts: She appears to be this with Seiji, since they're always seen cuddling and acting lovey-dovey. Their relationship actually is extremely disturbing.
  • Sinister Surveillance: With her hacking skills and a good amount of tiny devices, she keeps track of every character in the series 24/7, without remorse of violating their privacy. Though the only information she cares about is in which Seiji is involved.
  • Snark-to-Snark Combat: The entire fight she had against Namie in the warehouse consist mostly in one... and surprisingly enough she won the first round which put Namie in bersek mode.
  • Softspoken Sadist: She was all cheerful and happy while telling Namie how she planned to crush and eat Celty's head until the last drop of blood and the last strand of hair.
  • Stalker with a Crush: She had stalker tendencies before Seiji came into her life, and since then she has taken her stalking Up to Eleven. She says she's snuck 20 hidden cameras in his room. Later, she reveals she's been wire-tapping everyone remotely associated with Seiji ever in an effort to "protect" him. She's such an expert in stalking that the others bring her in as a consultant when Ruri has a stalker.
  • Stalking Is Love: Apparently, Seiji is not all that bothered by her extreme stalker tendencies. Averted in the manga where he's at least shown to be disturbed by it
  • Super Reflexes: She could quickly blocked the scissors that Namie threw at her with her spade. This the fist scene when we can assume there is something... unsettling about her.
  • Supreme Chef: She gets a 100% rating for her cooking skills.
  • Surgical Impersonation: Of Celty's head so that Seiji would love her.
  • They Look Just Like Everyone Else!: Even though everyone knew she was a stalker, just by her dizzy and spaced-out looks, no one could even predict that she is probably the most well informed character in the series.
  • Too Dumb to Live: She breaks into the room of a guy who barely knows her and loudly announcing her presence to him, without maybe considering first that he might be dangerous.
  • Unreliable Expositor: One of the statements Mika made was that Mikado, Anri and Masaomi don’t know the secrets of each other, when actually they knew but Mikado and Anri were waiting Masaomi to come back to Ikebukuro to share them. This could be because Mika began stalking everyone after the end of season one and adding the fact that the trio don’t talk about their secrets, there’s no way she could’ve known about it with her devices.
  • Walking Spoiler: Just knowing her name is a huge spoiler for the first arc of the series.
  • Yandere: If you thought actually getting together with Seiji would make her lighten up on the crazy stalking, you'd be wrong. And then there's the fact that she's planning to eat Celty's head if she ever finds it.

"You'll come back. That's how things are. So you can love all the other girls you want, and I don't care. In the end you'll love me more than you love them."

A young woman currently residing in the hospital who is Masaomi's (ex?) girlfriend and follows Izaya's orders to the very letter.

  • Abusive Parents: Implied to have these. They definitely weren't visiting her in the hospital, and it explains her initial dependency on Izaya.
  • Clingy Jealous Girl: The primary reason she returned to Ikebukuro to talk to Anri was to "declare war" on her should Anri have feelings for Masaomi. However, she later drops the act upon learning that Anri is still trying to learn about what it means to love and regards Masaomi as something other than a love interest.
    "I came here ready to declare war on you. If you had feelings for Masaomi too, then I thought we'd be in for some serious carnage. If that were the case, I would be like 'I'm not letting you have Masaomi, you thieving cat!' At least, that's what I was thinking."
  • Cold-Blooded Torture: Both her legs were broken due to a plan by the Blue Squares' leader to lure Kida out.
  • Curtains Match the Window: After her hair fades to its original colour. In flashbacks and in season 2, it's dyed brown.
  • Disabled Love Interest: Subverted. It turns out she was faking it.
  • Extreme Doormat: She'll listen to whatever Izaya tells her to do, even if it means endangering her life. Even after she betrays him, she continues loyally obeying him afterward, too.
  • Fangirl: For Izaya until she gets over him.
  • Heel–Face Turn: Originally working with and obeying Izaya to manipulate Masaomi, her growing love for him allows her to betray Izaya by spilling his secrets to Simon.
  • Honey Trap: And Kida knew this from the beginning but went along with it anyway. He even knew that Saki was feigning illness to make him feel guilty, but he also went along with it.
  • Insecure Love Interest: Averted for the most part, but after talking with Anri in Episode 6 of x2 Ketsu and seeing how kind she is, Saki begins to wonder how serious Masaomi's relationship with Anri really is and what that means for her.
  • I Want My Beloved to Be Happy: Saki is the one who motivates Kida into returning to Ikebukuro for Anri and Mikado
    "You can always come home to me, Masaomi. Don't forget that. But I won't be able to help your friends. That's something only you can do, isn't it?"
  • Lazy Bum: Morally so; she pretty much flat out tells Masaomi, "just don't bother making up your own mind because Izaya will take care of everything for you!"
  • My Master, Right or Wrong: Saki worships the ground Izaya walks on, and even admits that if he told her to jump off a cliff and die, she would do so. Subverted at the end when she betrays him out of love for Masaomi, spilling the beans on Izaya's plans to Simon.
  • Official Couple: With Masaomi.
  • Perpetual Smiler: Saki always has a serene smile on her face, no matter what happens to her. The only times she stops smiling is in situations regarding Masaomi, such as when she phones Russia Sushi and confesses to what Izaya has been doing all along.
  • Satellite Love Interest: She's seen as this to some people because her background isn't really explained. After all, she was working with Izaya to get close to Kida, thus her personality isn't fleshed out like most of the characters.
  • Walking the Earth: Leaves Ikebukuro with Kida at the end of the series after they reconcile. The happenings inside the city soon force him to return, and she decides to tag along for the ride.
  • Yandere: The way she talks to Kida about them being "destined" has shades of this but she's a mild example. Unlike others, she's truly ok with him seeing other girls because she believes they're Romantic False Leads.
  • You Can't Fight Fate: Says that she and Kida are destined to each other whether he likes it or not, and so it's ok with her if he sees other girls because no matter what he will always come back to her, because "Izaya says so."

    Kasuka Heiwajima (stage name "Yuhei Hanejima")
Voiced by: Daisuke Kishio & Kanae Oki (JP), Blake Lewis (season 1), Vic Mignogna (season 2) (EN)

A famous model and actor who got his start after saving a talent scout who made the mistake of attempting to scout his older brother Shizuo. While amazingly talented as an actor, Kasuka's natural demeanor is very robotic and unemotional.

With the occasional mention of his brother aside, Kasuka usually keeps his personal and family life under wraps. Journalists who insist on interviewing his family usually find their cars mysteriously overturned.

Affiliated with the Dollars, by proxy of Shizuo.

  • The Ace: Ridiculously pretty, brilliant, talented in everything (his list of hobbies is The Long List), filthy rich, extremely popular, and everything that can possibly make his brother Shizuo look horribly inadequate in comparison (Shizuo himself adores him, but it is killing his self-esteem — he doesn't even like having their names mentioned in the same sentence because he thinks it's insulting to his brother).
  • Accidental Athlete: Accidental actor, actually, but the principle is the same.
  • Aloof Big Brother: Inverted. He's the younger brother. He was rather aloof and unemotional from the very start. Doesn't stop him and Shizuo from being close, though.
  • Ambiguous Disorder: He claims that he feels no emotion and have difficulties understanding other people. The reason he became an actor is so that he can "feel".
  • Awesome, Dear Boy: In-Universe: Kasuka seems to have a soft spot for his B-movie vampire ninja character, Carmilla Saizou. He even quotes his lines in life or death situations.
  • The Beard: In the second season, he and the Idol Singer/Serial Killer Ruri decided to pretend to be couple in order to rile up the reporters that had surrounded the entrance to Kasuka's apartment as a way to keep Nebula's employees from getting close to Ruri.
  • Becoming the Mask: His couple act with Ruri was initially meant to be a temporary ruse, but they develop genuine feelings for each other later on.
  • Birds of a Feather: With Ruri. They're both emotionally distant idols who sync together perfectly.
  • Bishounen: He's a popular actor known for his incredible good-looks. The novels really drive this point by saying that the word "beautiful" might as well be made to describe him.
  • Broken Ace: Brilliant (he managed to turn a million yen into 1.2 billion in a month just from smart investing), talented, does his own stunts, looks like he walked out of a shojo manga, and can even sing. He also admits that he doesn't actually feel emotion at all unless he's in a role — In Ruri's words, he's "a monster who wants to be human."
  • Bunny-Ears Lawyer: Apart from his unnervingly Stoic, there have been anecdotes of strange behavior such as nonchalantly attempting to sever his own pinky finger or unnerving a stalker badly enough to turn themselves in to the police.
  • Cloudcuckoolander: Kasuka is... odd. For example, he assumed that the reason his brother kept changing jobs was because he didn't have enough clothes, so he bought him a whole bunch of bartender uniforms so that he could keep that job.
  • Creepy Monotone: When he's not on the job.
  • Cross-Cast Role: Kasuka's faux-encyclopedia entry notes that he's done a few crossdressing/female roles...
  • Dull Surprise: Kasuka is capable of showing (fake) emotion when he's acting, but in real life...
    Shinra: You need to smile a little bit when you give cats to other people to pet. Otherwise it's just scary.
    Kasuka: ...But I am smiling.
  • Early-Bird Cameo: Cameos in the anime for an episode even though he wasn't properly introduced until volume 4.
  • Emotionless Boy: He can't express any emotion unless he's playing a role.
  • Empty Eyes: Kasuka's eyes are always flat and non-reflective, to further emphasize his incapability to emote.
  • Expy: Kasuka bears an uncanny resemblance to Baccano!'s Charon Walken, which is noted by Saki in volume 8.
  • Florence Nightingale Effect: How he meets Ruri. He finds her after she was sent flying by his brother while she was in one of her Hollywood disguises. He then takes her to his apartment where he takes care of her until she heals (which is fast thanks to her regeneration powers) and promises to not reveal her identity to anyone.
  • I Just Want to Be Normal: According to Ruri, he's a "monster trying to become human".
  • Kindhearted Cat Lover: He loves cats, and owns one that is named Yuigadokusonmaru.
  • Large Ham: While acting, Kasuka really gets into the role.
    • In the second OVA, Simon kidnaps him and his film crew and takes them to Russia Sushi to keep them from filming Celty. Kasuka just rolls with it, and turns it into a kind-hearted critique of the restaurant.
    Kadota: I can't believe they're still filming this.
  • Lookalike Lovers: He has more physical similarities with his eventual girlfriend, Ruri Hijiribe, than with his actual older brother.
  • Master Actor: Again, normally he has zero emotion. But you wouldn't be able to tell from his acting.
  • Ninja Pirate Zombie Robot: In his first big movie role he starred as a Vampire Ninja.
  • Old Shame: An In-Universe subversion. Kasuka got his big start as a breakout actor in an otherwise very campy Toku series. While everyone else seems to regard it as an Old Shame (He ranked #3 on a countdown for "Best Actors and Actresses Who Don't Get To Pick Their Roles"), he asserts that Vampire Ninja Carmilla Saizou is an awesome character and insists on reprising the role in the series' movie.
  • One Head Taller: Than Ruri.
  • The Quiet One: Outside of his job, he rarely talks unless necessary.
  • Secret Keeper: He knows Ruri is the serial killer Hollywood, but he promises to not tell anyone.
  • Seen It All: The completely deadpan type.
  • Shout-Out: Some of the items listed on his faux-Wiki page (particularly his manager's claim that he's a thousand-year-old vampire) are suspiciously parallel to a certain real-life performer.
  • Sibling Yin-Yang: He's stoic and unemotional. His brother Shizuo has a Hair-Trigger Temper.
  • Significant Anagram: The kanji used for his stage name can be rearranged to form his real name.
  • Significant Birth Date: His birthday is on the national cat day in Japan.
  • Stage Name: His real name is Kasuka Heiwajima, but he uses the name "Yuhei Hanejima" for his acting career.
  • The Stoic: A razor-sharp contrast to Shizuo.
  • Sugar-and-Ice Personality: He may be emotionless like a robot, but he really cares about his brother and his girlfriend Ruri and he also has a soft spot for his cat Dokunsonmaru.
  • Teen Idol: Was a celebrity since his early youth.
  • Tin Man: His reason for becoming an actor is because he wanted to feel the emotions that other people feel through his roles.
  • Took the Bad Film Seriously: In-universe; Kasuka has a habit of both a) taking pretty much any role that's offered to him ever, no matter how silly (see the aforementioned Vampire Ninja), and b) acting the hell out of it anyways.
  • Too Spicy for Yog-Sothoth: Kasuka once scared a stalker into turning themselves in to the police simply by sitting quietly. For twenty hours.
  • When He Smiles: See for yourself. Too bad it's all fake.

    Rio Kamichika
Voiced by: Haruka Tomatsu (JP), Stephanie Sheh (EN)

A girl who ran away from home after discovering her father was having an affair and was later kidnapped and rescued by Celty. She was an anime-only character by Narita at first, but then he later used her as a minor character in the novel.

  • Canon Immigrant: Originally an anime-only character, but later shows up in the Light Novels as one of the girls Chikage hooks up with while in Ikebukuro.
  • Continuity Cameo: Her minor appearance in the light novels.
  • Conveniently Seated: Rio has a window seat from which she can stare out wistfully and contemplate the world and its many odd inhabitants.
  • Curtains Match the Window: After she changed her image.
  • Demoted to Extra: The second episode of the entire series revolves around her, after which she only has occasional cameo appearances. This is because she was created for the anime, which took some creative liberties in Izaya's introduction.
  • Girlish Pigtails: Usually has short pigtails.
  • Interrupted Suicide: Izaya talked her into it and Celty interrupted it.
  • Meganekko: Again, before she changed her image.
  • The Runaway: Left home so she could end her life.
  • Suicide Pact: With Izaya of all people. Though she didn't go through with it, and he never intended. This was the core of Izaya's Breaking Speech that lead to the above trope.

    Tom Tanaka

Ikebukuro's resident "Debt Collector" and was Shizuo's Sempai in middle school. He's a pretty nice and normal guy that keeps Shizuo under control when he rages.

  • All Devouring Black Hole Loan Sharks: Subverted; Tom is generally a pretty nice guy and would rather avoid violent confrontation. He employs Shizuo mainly to use his name to scare his clients into paying him back on time, since only a complete idiot would pick a fight with Shizuo Heiwajima. Guess what kind of people a debt collector meets?
  • Alliterative Name: Tom Tanaka.
  • Ambiguously Brown: Has noticeably darker skin than many characters, not to mention the dreadlocks, and his name suggests that he might have some non-Japanese ancestry.
  • Benevolent Boss: One of the main reasons Shizuo is able to keep his job.
  • Distressed Dude: Back in middle school, some other kids would occasionally get the idea that kidnapping Shizuo's sempai would give them leverage in a fight. This is because they were idiots.
  • Face Palm: Default reaction when someone (usually the person he's getting to pay their debt) pisses Shizuo off.
  • Heterosexual Life-Partners: With Shizuo.
  • Improbable Hairstyle: Sports dreadlocks, very neat ones at that, probably not all that improbable from a maintenance prospective, but is somewhat rare in the world of anime.
  • Kid with the Leash: Subverted, as Tom takes offense at the suggestion — Shizuo is his friend, not his attack dog.
    Tom: The kid's not a dog, and he's not on anyone's side to begin with. You try talking to him and you'll know. He's far more normal than you may think.
  • Kick the Dog and/or Kick the Son of a Bitch: In Izaya's flashback he is seen stepping on the head of Takashi Nasujima-sensei as Nasujima lowers his head begging for mercy. It's also possible he's kicked other puppies collecting from debtors that are are Too Dumb to Live or just dirt-poor. It's strictly professional, of course.
  • Megane: He really rocks those dreadlocks and spectacles.
  • Multiethnic Name: Has an English first name and a Japanese last name.
  • Nice Guy: He's the first person to show Shizuo kindness.
  • Non-Action Guy: In his own words, "I'm just not good at fighting."
  • Only Sane Man: Compared to most of the cast, he's a very mellow guy that prefers to use his brains instead of his fists.
  • Pet the Dog: In anime filler, he was comforting a girl whose boyfriend is the debtor he was chasing.
  • Sempai/Kohai: Shizuo's sempai.
  • Weak, but Skilled: Let us reiterate, he is the only person who knows how to prevent Shizuo from raging, or keep him under control when he inevitably starts.

    Shingen Kishitani
Voiced by: Akio Ohtsuka (JP), Doug Stone (EN)

Shinra's father and source of most of his weirdness, Shingen was living in America up until recently, when he decided to return to Japan and impose himself on his son for reasons he has yet to disclose. Believing Tokyo's air to be terribly filthy and unfit for breathing, he opts to wear a gas mask 24/7.

  • Brother Chuck: Drops off of the radar completely after episode 14, one episode after he was introduced. He reappears with a slightly bigger role in Durarara!! x2.
  • Bunny-Ears Lawyer: He's a brilliant doctor by all accounts, but he's obsessed with air pollution, hence the gas mask.
  • Cloudcuckoolander: No one who looks that menacing should act that goofy.
  • Cool Mask: His mask has what look like devil horns, a contrast to the cute-looking cat ears on Celty's helmet.
  • Crouching Moron, Hidden Badass: Was able to wield Saika in the past, without being driven insane by it.
  • Did I Just Say That Out Loud?: A self-acknowledged flaw.
  • The Faceless: His face was never shown in the anime.
  • Fan Disservice: Was on the receiving end of an invoked Shower of Awkward by Shinra, who thought it was Celty in the shower.
  • Gas Mask, Longcoat: Always wears a doctor's smock and a gas mask because Tokyo's air is just so terrible. The mask stays on even when he's naked in the shower, as Shinra witnessed to his misfortune. He later hires Egor and Eijirou to help him get revenge for his son getting beaten up and they end up wearing identical gas masks.
  • Large Ham: Generally, at the others' expense.
  • Mad Doctor: And for "mad" we mean "totally bonkers" here.
  • Papa Wolf: According to the novel, Shingen cut off Celty's head and sold Saika's sword off to Anri's parents in order to protect Shinra from Namie's grandfather who threatened to kill Shinra if he didn't.
    • When he discovers that Shinra was beaten up by Ruri's stalker and one of Shingen's friends was the reason for it, Shingen doesn't hesitate to call and warn him that he'll kick his ass for it.
  • Parent with New Paramour: Vol. 4 and the first episode of Durarara!! x2 reveals that Shingen remarried while he was in America — to a woman younger than his son.
  • Why Couldn't You Be Different?: Why couldn't you not be sexually attracted to headless women, Shinra? He has accepted it by Season 2, and then insists that Celty refer to him as "father(in-law)".

    Kinnosuke Kuzuhara

A motorcycle cop brought in to Ikebukuro to take down Celty. Often just a little bit too into chasing down suspects, to the point that he causes as many accidents as he prevents.

  • Advertised Extra: Despite getting billed as a main character in the second opening, his appearance and role is pretty minimal.
  • Alliterative Name: Kinnosuke Kuzuhara.
  • Badass Biker: He's always on it and he always drives well.
  • Badass Boast: "Don't jack with the cops, monster."
  • Catch Phrase: "Don't screw with the traffic cops."
  • Cool Bike: As a police officer who uses a motorcycle to get around, this is to be expected.
  • Cowboy Cop: Once Celty's on his sights, he will do whatever it takes to catch her so he can finally give her a fine for all the times she broke traffic violations.
  • The Dreaded: At least for Celty.
  • Genre Savvy: "I often think about how people like us tend to be the weak foils to stars like you in fiction..."
  • Hero Antagonist: He seems like an asshole, but while it's totally true he's overzealous in doing his job, he also is justified in wanting to curb the activities of a reckless motorist, which Celty tends to be.
  • Inspector Javert: He's obsessed with trying to convict Celty for violation of traffic.
  • Meddlesome Patrolman: He's always trying to stop Celty, regardless of what she's doing.
  • No Celebrities Were Harmed: He bears a pretty good resemblance to Clint Eastwood. The dub takes it even further by having his voice be a Clint Eastwood impression.
  • Pre-Asskicking One-Liner: To Horada in episode 24 - "You know it's a bad idea to swerve dangerously next to a cop with his lights off. Don't screw with the traffic cops, boy."
  • Red Shirt: Lampshaded mockingly by Kinnosuke during his confrontation with Celty.
  • Scarf of Asskicking: Usually seen with a red scarf.
  • "X" Marks the Hero: Has an x-shaped scar on his right cheek. His niece Shinju Kuzuhara has a similar scar on her left cheek, so it could even be a genetic birthmark.

    Shuji Niekawa
Voiced by: Rikiya Koyama (JP), Joe J. Thomas (EN)

The father of Haruna and a news reporter writing a magazine story on the strongest person in Ikebukuro (i.e. Shizuo).

  • Intrepid Reporter: He even pays a visit to the local mafia in order to get his story.
  • Mind-Control Eyes: While possessed by Saika. Twice.
  • Parental Obliviousness: He didn't know why Haruna had to transfer out of her old school, or about her possession by Saika.
    • When he returns in x2, he's searching for her when she ran away, showing that he learned his lesson on this. However, his daughter is so far gone she tries to send him away by reinfecting him with Saika.
  • Perma-Stubble: Subverted, because he isn't particularly badass.
  • What Happened to the Mouse?: After getting possessed by Saika, and presumably returning to normal when everything settles again, it's never explained what happened to his exclusive story on the strongest man in Ikebukuro.
  • When You Coming Home, Dad?: To the point of not realizing there's something... wrong with Haruna.

    Haruna Niekawa
Voiced by: Mai Nakahara (JP), Sandy Fox (EN)

A high school student who mysteriously transferred out of Raira Academy after an incident involving her and Nasujima.

  • All Take and No Give: Her relationship with Nasujima was implied to be this, since Haruna mentions having to give him money to keep him happy. Not that she minded, as long as he loved her back.
  • Ax-Crazy: It's very clear that the break up with Nasujima and said person lusting for Anri has made her very unstable. She's more than willing to spread Saika's love, especially if it means making Anri suffer.
  • Clingy Jealous Girl: Haruna hates the very idea that Takashi is in love with someone else. Her solution to that is very simple.
  • Dissonant Serenity: Always has a creepy, serene smile on her face.
  • Empty Eyes: She always has those blank eyes with no eyeshine, which only make her look even more creepy and crazy.
  • Evil Plan: Track down her beloved Nasujima-sensei is half of it. The other half is spreading Saika's love around.
  • For the Evulz: While speaking with Anri for the first time, she tells Anri that she wants to kill her friends and force her to watch, something that will do absolutely nothing to benefit her.
  • From Nobody to Nightmare: Haruna used to be a normal girl before she was attacked by the Slasher and became one of Saika's children. It all went downhill from there.
  • Girl with Psycho Weapon: Since she's The Slasher and a wielder of Saika, she can use any sharp instrument to cut people into her control.
  • Hive Queen: Of Saika's children, before Anri defeats her. Once Haruna was slashed, her children become Anri's.
  • Hot for Teacher: The reason why Haruna transferred schools is rumored to be because of her affair with Nasujima-sensei. In reality, it was because she was caught trying to cut him with a knife to physically verify their love.
  • Hypocrite: Calls Anri a "skank" that flings herself onto other men for comfort when she does the same thing when she sees Nasujima-sensei.
  • Knife Nut: Naturally, since she's The Slasher.
  • Lack of Empathy: Despite claiming to be Saika and love everything because of Saika, she shows no empathy when Anri shows her how she's able to block out Saika via showing her the past with her abusive father. Her response is to just keep attacking.
  • Legion of Doom: Is a member of Izaya's crew during his "comeback."
  • Love Makes You Crazy: She has not gotten over her breakup at all.
  • Mad Love
  • Messy Hair: Her long black hair is pretty unkempt.
  • Missing Mom: Her mother's status is unknown.
  • More Than Mind Control: Unlike the other "children" of Saika, Haruna is the only one who is aware at all of Saika's presence and fully embraces it after initial misgivings. Of course, she still can't fully forgive Anri.
  • Murder the Hypotenuse: She wants to kill Anri to make her pay for "stealing" Takashi away from her.
  • Pretend to Be Brainwashed: She pretended to be under Takashi's control because that's what he wanted from her. Once she reveals she was the one in control the entire time, he freaks out and tries to run away, but Haruna catches him. Takashi being run over by Kadota's gang for his own hit-and-run attempt on the latter helped.
  • Psycho Ex-Girlfriend: Of Nasujima.
  • Rapunzel Hair: Has black hair that goes down to her thighs.
  • Red Eyes, Take Warning: While possessed by Saika, her eyes turn red.
  • Sinister Scythe: She is shown wielding a large red scythe in volume 9 of the light novels.
  • Slasher Smile: After being revealed as The Slasher, she sports a scary one when attacking.
  • Smug Snake: Always has a smug, even sinister smile on her.
  • Uncanny Valley Girl: Especially when she's using her Slasher persona.
  • Ungrateful Bitch: Even though Anri spared her of being controlled by Saika, she still wants revenge on her.
  • Yandere: She's determined not to let her love for Nasujima be denied.

    Takashi Nasujima
Voiced by: Yuji Ueda (JP), Kirk Thornton (EN)

A teacher at Raira Academy who takes an interest in Anri.

  • Always a Bigger Fish: He starts a Zombie Apocalypse and nearly takes over the entire city, but only because none of the people with the power to stop him happened to be paying attention at the moment. Anri is moving to stop him when Celty does it for her.
  • Asshole Victim: Suffers the most horrific fate of the entire cast, but there is no pity to be had for such a Hate Sink like Nasujima.
  • Big Bad Wannabe: Tries to take over all of the action in Ikebukuro after he returns and takes control of Haruna's children, including Shizuo himself. Works about as well as you'd expect.
  • The Bus Came Back: He shows up in the second half of x2 after being absent from the series since Season 1's first half.
  • Butt-Monkey: The poor guy is in trouble with lots of people. And constantly finds himself being thrust into worse situations. But, then again, he deserves it... maybe.
  • Curtains Match the Window: Brown eyes and hair.
  • Evil Teacher: Double subverted. During his employment at Raira, he's more of an unsympathetic creep than he is an actual villain. Come Season 2, however, he becomes a sinister, sick-minded bastard who kidnaps Haruna and uses her to take full control of the Saika Army.
  • Evil Is Not a Toy: While he successfully manipulated Haruna's feelings and gained control of Saika for a while, Haruna eventually breaks free from his control and decides his plans aren't favorable to what she has in mind for them.
  • Hate Sink: Not easy to like a slimeball teacher who has a thing for high school girls, like Anri. He gets much worse in season two, where he tries to take over the city using Saika.
  • Fate Worse than Death: At the end, Haruna has Nasujima imprisoned in one of Izaya's old hideouts converted into a BDSM dungeon. She expresses her intent to have her wildest erotic fantasies with him forever, obviously without his consent.
  • Hot for Student: Dated Haruna Niekawa, who transferred school supposedly because of their relationship, but changed his preferences to Anri. This changes after he finds out Anri is the original possessor of Saika and runs away in fear following her fight with Haruna, who was thought to be Saika.
  • Laser-Guided Karma: Nasujima was the culprit behind Kadota's hit and run. When he is trying to hitch a ride in Togusa's van in an attempt to get away from Haruna, Kadota recognizes him as the guy behind the car that ran him over prompting Togusa to run him over. He is then punished further by being Haruna's captive.
  • Made of Iron: It might be because of Saika, but he's been punched by Shizuo, hit by a van, and still managed to come out unharmed.
  • Mugging the Monster: A panicked Nasujima runs from Anri and tries to rob the first person he sees — who happens to be Shizuo.
  • Not-So-Harmless Villain: He intentionally runs over Kadota, causing a lot of problems in the story. And while he's later ousted as a Big Bad Wannabe, his last act in the story is viciously stabbing and almost killing Mikado.
  • Roaring Rampage of Revenge: After resisting control of Kasane's Saika, he decides to get revenge on Ikebukuro by taking control of Haruna's children by slashing Haruna herself. Her children become his and he orders them to slash as many Ikebukuro denizens as possible.
  • Stalker with a Crush: He tends to follows Anri around quite a bit during school and even tries to visit her apartment in Episode 16.
  • Smug Snake: Takashi has definitely evolved into this after he resisted and overpowered Kasane's Saika and possessed both Haruna and her 'children'. Subverted when it turns out Haruna was in control all this time, and had faked her possession.
  • Villainous Breakdown: Attempts to stab Anri when his Saika takeover plan fails, but Mikado gets in the way, which causes him to lose it and stab him multiple times. When Haruna reveals that she had only pretended to be brainwashed, Takashi runs away screaming only to be run over by Saburo in retaliation for putting Kadota in the hospital.
  • Wig, Dress, Accent: Wears a beard and a pair of sunglasses to disguise himself when he returns to Ikebukuro.
  • Zombie Apocalypse: Winds up creating something like it in x2 after he takes control of Saika, intending to infect everyone and take the spotlight for himself.

Voiced by: Wataru Takagi (JP), Kyle Hebert (EN)

A jerkass member of the Yellow Scarves who becomes an antagonist in the second half of the series.

  • Big Bad Wannabe: Views himself as a credible threat and criminal genius ready to take the the city by storm. While he causes a lot of trouble, he's largely a pawn to Izaya.
  • Butt-Monkey: He gets (deservedly) beaten-up a lot.
  • Dirty Coward: He always gets other people to do the dirty work for him or claim that he's doing jobs for somebody else.
  • Ephebophile: Seeing Anri's er, assets, gives him a nosebleed.
  • Expy: Often compared to Dallas Genoard of Baccano!.
  • Hoist by His Own Petard: He and his fellow members of the Blue Squares managed to join the Yellow Scarves because nobody ever bothered giving them a background check after their old gang disbanded. One of the events leading to his arrest is the revelation that a number of Dollars pulled the same trick on him during his own recruitment drive after kicking out all of the Kida-sympathetic Scarves.
  • Hate Sink: Horada is irredeemable gutter trash. He instigates violent unprovoked attacks on the Dollars, including Takiguchi, simply because he can. Besides Shizuo, Kyohei, and Simon, most of them aren't even a threat to him. He's also scheming to usurp Masaomi's position as leader of the Yellow Scarves and rule the streets of Ikebukuro. It doesn't help that he's a former member of the Blue Squares, who were well known for their brutality when fighting the Yellow Scarves in the past.
  • Humiliation Conga: He gets an eminently satisfying one in episode 24.
  • Ineffectual Sympathetic Villain: Heavy on the ineffectual, low on the sympathetic.
  • Jerkass: He seems to have no qualms about causing a ruckus when necessary, even shooting Shizuo.
  • Kick Them While They Are Down: Does he ever.
  • The Mole: He was previously a member of the Blue Squares, but joined the Yellow Scarves after his old group was defeated, and gradually infiltrated them with other former Blue Squares.
  • The Starscream: He usurps Masaomi's position as leader.
  • Smug Snake: He's a stupid thug and one of Izaya's pawns, but thinks of himself as a criminal mastermind.
  • Small Name, Big Ego: See Smug Snake above.
  • Too Dumb to Live: As soon as his plans to take over the Yellow Scarves falls apart, it's apparent how much of a moron he really is.
  • Why Did It Have To Be Shizuo Heiwajima/Ran Izumii?: Is absolutely terrified of both figures after getting out of jail and desperately tries to avoid both of them. He of course ends up meeting both.

    Ryo Takiguchi
Voiced by: Nobuhiko Okamoto (JP) Sam Riegel (EN)

A fellow classmate of Masaomi, Ryo Takiguchi is just an average joe who likes composing his own music, playing on a harmonica, and just so happens to be a member of the Dollars. He is later targeted by members of the Yellow Scarves, who beat him up horribly and leave his unconscious body next to graffiti as part of their self-declared war against the Dollars. He considers leaving the organization afterward, but just can't bring himself to do it in the end, and sticks around to help out.

  • Bishounen: Just look at him!
  • Canon Foreigner: A minor character who was only introduced in the anime version.
  • Collateral Angst: Poor Takiguchi gets beaten up brutally by several of the Yellow Scarves who are actually former members of the Blue Squares. However, being a minor character, his suffering is mostly ignored in favor of Mikado's angst about Dollars in general.
  • Curtains Match the Window: Black hair and black eyes.
  • Defector from Decadence: Takiguchi briefly considers leaving the Dollars after realizing they've lost their original non-color ideology, but ends up changing his mind again because of Team Spirit with the other members of the Dollars.
  • Delinquent: Mikado assumes this at first, but it ends up being a misunderstanding.
  • Innocent Bystander: At first, but he later becomes a Heroic Bystander when he's given the chance to help out.
  • Laser-Guided Karma: After getting beaten up by Horada's gang, Takiguchi gets some karmic retribution when he happens to be in front of a stack of boxes in a shop, right when Horada is passing by. Naturally, he "accidentally" pushes them over at this point, and causes the whole pile to fall on Horada and slow him down.
  • Last-Name Basis: Everyone who knows him just calls him Takiguchi.
  • Nice Guy: Which makes his subsequent, undeserved assault by the Yellow Scarves even more cruel and painful to watch.
  • No-Holds-Barred Beatdown: The unfortunate victim of one. The beating is so severe, Takiguchi has to be hospitalized for a while afterward.
  • #1 Dime: A subtle example. Moments before he is attacked, his harmonica falls out of his pocket and is subsequently smashed by the bat that one of the thugs brings along.
  • Open Secret: Unfortunately, Mikado and Masaomi weren't the only ones who knew he was secretly a member of the Dollars...
  • Peek-a-Bangs: One lock of hair partly covers his left eye.
  • Sitting on the Roof: He is apparently fond of sitting on the school's roof during his lunch break to compose his own music and play his harmonica.

Voiced by: Shiori Izawa (JP) Laura Bailey (EN)

A blonde foreigner who is introduced in the anime version as another member of Dollars. Her real name is unknown, although her username is called Siri. She carries around a "Most Desired Object" sign in Episode 8, asking people to write down what they're looking for in a journal, and later helps Anri escape from Horada and his gang.

Voiced by: Toru Okawa (JP), David Lodge (EN)

An illegal immigrant from Italy. He is friends with Dotachin Kyohei's gang. Affiliated with the Dollars.

  • Anime Accent Absence: Justified in this case — Italian has pretty much the same pronounciation for words as Japanese.
  • Beady-Eyed Loser: The only character with these kinds of eyes.
  • Big "NO!": Sort of. His e-mail address is "kaztanooooooo".
  • Funny Foreigner: He's the goofiest of the foreigners by far.
  • Guile Hero: Attempts this in his intro episode to escape a kidnapping, but isn't very successful. He gets to be a more successful example when he and the other Dollars work together to save Anri from Horada.
  • The Illegal: He's an illegal immigrant from Italy.
  • Lost in Translation: The dub gives him quite a thick Italian accent while Japanese dialogue is replaced with English, which makes his attempts to pass himself off as Japanese sound utterly ridiculous.
  • The Nicknamer: Kaztano seems to have a habit of adding "no" to the end of names to make them sound Italian, e.g. "Togusano" and "Dotaccino".


A trio of ganguro girls from Raira academy who frequently picked on Anri, until the Slasher attacked them.

  • Asshole Victims: All three got attacked by the Slasher when bullying Anri in episode 13.
    • Soon, they are later beaten down by Shizuo.
  • The Fake Cuties: Their cutesy accesories and heavy use of makeup suggests this.
  • Gang of Bullies: They constantly harass Anri.
  • Hypocrite: All three of them like to spout that Anri is a slut who likes to seduce men, when it's the exact opposite. Given the places they like to hang out and what kinds of boyfriends they have, it can probably be assumed that they're much worse than Anri in this regard.
  • Mind-Control Eyes: When they get possessed by Saika.
  • Sarashi: One of the three girls wears this.
  • Terrible Trio: Their spoiled attitudes give Anri a hard time.
  • You Gotta Have Blue Hair: One of them dyes her hair pink.

Voiced by: Hiroki Yasumoto (JP), Kirk Thornton (EN)

The boyfriend of one of the Ganguros'. He is also a fake member of Dollars.

  • Butt-Monkey: Every time he shows up, he usually gets his ass kicked.
  • Character Tics: He has an odd habit of touching his lower regions while talking to people.
  • Delinquent: Pretty much a gangsta wannabe that only does minor infractions.
  • "Hey, You!" Haymaker: Becomes a victim of one; in the second OVA, Mairu introduces herself with a handstanding kick to the face right after he rudely bumps her sister, Kururi.
  • Ineffectual Sympathetic Villain: Not a dangerous villain by any means, but he does get beaten up a few times for being a jerk.
  • Jive Turkey: "Yo yo yo... Hey, man!"
  • Nice Hat: A black ski cap.
  • Traumatic Haircut:
    • Izaya somehow manages to shave nearly half his hair off in the blink of an eye.
    • This happens again in season 2, only with Anri on the delivering end via Saika.

    Haruya Shiki
Voiced by: Hochu Otsuka (JP) Dan Woren (EN)

An executive of the Awakusu-kai, Haruya Shiki is also one of its youngest members. He is the only Yakuza who uses honorific speech at all, except to his subordinates, and is the one responsible for dealings with the informant, Izaya. He is briefly seen in episodes 12.5 and 15 of the anime's first season, in the latter when the reporter Shuji Niekawa interviews him about the strongest person in Ikebukuro.

  • Perpetual Frowner: He hardly ever smiles when he's onscreen.
  • Pet the Dog: Often seen as a cold and ruthless person (for a good reason), but he does have a genuinely soft side in him, which he shows to Akane after finding her again.
  • Reasonable Authority Figure: Is surprisingly mellow for a gangster, when Shizuo is framed for murder of several Yakuza (by Izaya, of course), Shiki calmly and rationally deduces the fact that Shizuo was framed and lets him go.
  • Sharp-Dressed Man: Wears a white suit that never has a single scuff on it.
  • Smoking Is Cool: He is usually seen smoking a cigarette.
  • Yakuza: Like stated above, he's an executive of the Awakusu-kai gang.

    Sayaka Sonohara

Anri's mother.

    Ran Izumii
Voiced by: Atsushi Imaruoka (JP), Doug Erholtz (EN) (season 1), Robbie Daymond (EN) (season 2)

The leader of Blue Squares that got into a confrontation with the Yellow Scarves. He was the one that kidnapped Saki and broke her legs in order to get Kida to face his gang directly. He is foiled by Kadota's gang who turn on him and rescue Saki. He is then arrested and convicted thanks to Saki's testimony. After many years, he's out of jail and he wants revenge on the people who betrayed him and ruined his life.

  • Big Brother Bully: The things he did to his brother Aoba are unbelievable. For one thing, he came out unstable at the end of it all.
  • Cain and Abel: He is the Cain to his brother's Abel despite the younger being a manipulative bastard.
  • Disproportionate Retribution: He beat up on Aoba just because he thinks he's The Unfavorite of the family. However, Aoba hints that really isn't the case. And then finally, he goes past the limit of physically beating him up and does something else that makes the poor kid snap and set his room on fire. And while Aoba did trick him into becoming the leader of Blue Squares, he NEVER did anything to ruin his life. Before his brother beat up on him, he was acting his normal self but when the beatings started, he started becoming more crazy but even setting the room on fire is nothing compared to what Izumii did.
  • Dumb Muscle: Or maybe not, he did perform his role in Izaya's trolling of Earthworm and Shijima pretty well.
  • Evil Counterpart: Can be seen as this to Shizuo. Both are imposing men who regularly wear sunglasses, and the two share a penchant for violence which is accompanied by raw strength (even if Izumii doesn’t hold a candle to Shizuo). They also both have terrible tempers, younger brothers, and grudges against Izaya. However, Shizuo is a Nice Guy underneath all of his Berserk Buttons who wants nothing more than to control his anger, in contrast to Izumii who is a full-fledged Jerkass that Hates Everyone Equally and doesn’t care about improving himself. And while Shizuo is fiercely protective of his brother Kasuka, Izumii is a severe Big Brother Bully whose abuse had a profound negative effect on Aoba’s psyche.
  • Freudian Excuse: Not that it excuses his actions, but his belief that he's The Unfavorite seems genuine. Also, his father was shown to be physically abusive when Aoba lit his room on fire.
  • Gonk: In the anime, he was rather chubby and ugly. Getting set on fire and thrown in jail made him lose weight and part of his face.
  • Good Scars, Evil Scars: Definitely evil, with half of his face with ugly burn scars that emphasize his psychotic nature.
  • Hates Everyone Equally: During his A Day in the Limelight episode, he would call random people assholes during his narrations.
  • Jerkass: Has an awful temper and tends to take most of it out on a brother of his.
  • Jerkass Has a Point: While Aoba claims that their parents loved both of them, the only time we ever see their parents, his father isn't exactly shown to be the loving and understanding type.
  • No Smoking: Averted. While anime adaptations usally refrain from showing underage smoking, a flashback before he got arrested in the anime showed him smoking. Since it was mentioned that he was sent to juvenile hall, it can be assumed he was still a minor.
  • Offscreen Villainy: His abuse towards Aoba was only mentioned in the anime, and not with much detail. It makes Aoba setting his room on fire to get him in trouble seem more like Disproportionate Retribution.
  • Rape Is a Special Kind of Evil: Mikage would have let Izumii smash Earthworm's face in or set her on fire, but not rape her.
    • Averted in the light novels, where Mikage was perfectly okay with Izumii raping Earthworm.
  • Revenge: When he gets out of jail, he tells Izaya that he only used the Hot Pot group so he can get information on those he wants revenge on and kill them. He has his eyes set for Aoba, Kida, Kadota, Walker and Izaya. Crosses over with Disproportionate Retribution.
  • Scarf of Asskicking: To show that he's part of Blue Square, he's usually wearing a long, blue scarf.
  • Smoking Is Cool: Subverted. He likes smoking but Aoba uses this to his advantage to set his room on fire. This causes their dad to punch him and shout that it was his fault the room caught fire.
  • The Unfavorite: He thinks he's this compared to Aoba.
  • Unwitting Pawn: Aoba uses him to control Blue Squares. Of course, because he's a dumbass, he nearly ruins it for Aoba.
  • Would Hurt a Child: He didn't hesitate to beat his little brother. He was also going to rape a middle school girl after breaking her legs.
  • Would Hit a Girl: Or break her legs for that matter. And fingers. And shove a rag into her mouth and light it on fire.

    Mairu and Kururi Orihara

Voiced by:
Mairu: Eri Kitamura (JP) Candalee Whitmore (season 1), Gina K. Bowes (season 2) (EN)
Kururi: Hisako Kanemoto (JP) Candalee Whitmore (season 1), Bridget Hoffman (season 2) (EN)

The younger twin sisters of Izaya.

Mairu is the one on the right, in white. Kururi is the one on the left, in black.

  • Always Identical Twins: Subverted. Mairu and Kururi are fraternal twins despite the matching outfits and creepiness.
  • Animal Motifs: Dogs for Mairu. Cats for Kururi. Befitting their respective personalities.
  • Annoying Younger Siblings: Izaya does not like them at all. For what it's worth, though, they're not particularly fond of him either.
  • Badass Adorable: Especially Mairu, who she was capable of taking on the Yellow Scarves members single-handedly as seen in the second OVA.
  • Brains and Brawn: Kururi's the brains, Mairu's the brawn.
  • Cloud Cuckoo Landers: Probably the biggest ones in the cast.
  • Cool Big Sis: They're quick to take Akane under their wing once she starts training at their dojo.
  • Creepy Twins: They both consider themselves to be one half of a person and never separate from each other.
  • Custom Uniform: Both of them. Mairu wears a nonstandard black Sailor Fuku, while Kururi wears a gym uniform.
  • Custom Uniform of Sexy: Kururi's uniform emphasizes this aspect, since she opts to wear the school's gym uniform instead. This doesn't seem so bad until one realizes just how skimpy the bloomers are...
  • Cute and Psycho: They both can do some pretty rough things like nearly make somebody swallow a box of thumbtacks or set a student's backpack on fire.
  • The Dividual: Twindividual to be exact. They don't even consider themselves separate people.
    Shoro: You two are such a great pair. Honestly.
    Mai: We're not a pair.
    Kyo: We're one person. You're insulting the real pairs in this world by saying we're a pair. Though none of them are here to hear you, you should still apologize to them.
  • The Dog Bites Back: Bullying the crazy girls is highly ill-advised. Kururi will probably frame you for arson if you do, and we're still not sure what Mairu did to the last one that tried.
  • Early-Bird Cameo: The twins show up briefly in episode 8 of the Durarara anime note , but don't get properly introduced until episode 25.
  • Establishing Character Moment: In the books, Mairu is introduced reading schoolgirl fetish porn in the middle of class and commenting very loudly on the subject matter.
  • Fangirls: Both of them are raging Kasuka fangirls.
  • I Just Want to Be Special: Or as their brother puts it, "what a pair of intolerable eighth-grade-diseasenote  patients." When asked what he meant by that, he simply suggested googling it.
  • Intergenerational Friendship: With Shizuo, of all people.
  • Kick Chick: Both of them are, since Kururi has no problem with kicking men who are harassing her and her sister right in the groin, and Mairu doesn't mind flashing her panties when delivering her own powerful kicks backed by iron-plated shoes.
  • Lovable Sex Maniacs: Both of them, but Mairu is more obvious about it.
  • Ms. Fanservice: Both of them, but Mairu seems to like invoking this.
    • At one point, the two of them hung out with Aoba at the school pool while the latter had to think. Aoba ends up leaving because seeing them in swimsuits was "too distracting".
  • Meta Guys: Or girls, come the last two episodes during their chatroom appearances.
  • Morality Pets: To Aoba to the point where he outright states for Blue Squares not to involve them in this Gang War because he has taking a liking to them. Especially Kururi.
  • Noodle Incident: Whatever happened between Mairu and the schoolgirl bully she dragged into the lavatory, especially after Mairu emerges holding the girl's bra, is never explained.
  • Polar Opposite Twins: They deliberately cultivated themselves to be such, going as far as to flip a coin to see who got to have which trait. Izaya says that they don't actually consider themselves to be separate people, and that they're invoking the real-world equivalent of RPG party balance.
    • According to Shinra, this is a direct reaction against some of the emotional abuse Izaya put them through. When they were as young as five, Izaya would, as a social experiment, suggest to them that one of them should just kill themselves if they're just going to be identical, redundant copies of each other. Not quite being like other people, they decided the solution was to get out some dice, assign as many different character traits they could think of between them, and live with these new "personalities" for the rest of their lives.
  • Red Eyes, Take Warning: Just like Izaya, they tend to get depicted with devilish eyes.
  • Sibling Seniority Squabble: Averted. Mairu always addresses her twin as "Kuru-nee" (big sister).
  • Single-Minded Twins: Despite the Polar Opposite Twins personas, Mairu and Kururi don't actually consider themselves as individuals. This is best evidenced by the fact that, on the internet, the two switch roles entirely — Mairu's practically a Lurker while Kururi never shuts up.
  • Trickster Twins: They're called troublemakers by Izaya, and are completely uninhibited by social norms.
  • Twin Banter: Particularly on the internet.
  • Twincest: Mairu and Kururi are close, really close. They kiss on-screen.
  • Twin Threesome Fantasy: Invoked; They have no problem with hooking up with the same guy and they both really seem to like Aoba at the moment.
  • Verbal Tic: Kururi's speech is very brief and somewhat disjointed. She also almost never raises her voice above a whisper. On the internet, she speaks normally.
    • Averted in the second OVA, where she speaks complete sentences in a normal tone of voice.
  • Yuri Fan: After Kida tells a somewhat-dirty joke in the chatroom:
    Kyo (Kururi): Speaking of which, um... if Bakyura-san (Kida) is a female, I would really be confused as to how to react. If two females are to blow the same clarinet...and kind of kiss that would have been just beautiful and elegant and worthy of a place in my permanent memory. Should I say dreamy or unrivaled? Anyway, that's how I would feel.
    Mai (Mairu): So erotic!


  • Attack Hello: Mairu has been greeting Izaya with attempts to break his neck ever since Shizuo jokingly said he'd introduce them to Kasuka if they ever managed to kill him.
  • Big Sister Instinct: Inverted as she's the younger twin, but she has this towards Kururi. When the thugs in the second OVA knocked Kururi down, Mairu's response was to beat the shit out of them.
    • In the second season, she puts Kururi behind her and takes a stand when they encounter an injured Egor.
  • Cute Bruiser: She's skilled in martial arts. If a thug harasses her or her twin, you can bet that she'll kick their ass.
  • Genki Girl: She's the energetic twin and an absolute chatterbox with a manic smile.
  • Meganekko: Subverted. Mairu wears glasses, but she doesn't have the sweet and innocent personality to go along with it.
  • Murderous Thighs: In a fight with some thugs in the OVA.
  • Porn Stash: Mairu has one, although it's hard to call it a stash when she carries at least one porn mag on her person at any given time and reads them in public.
  • She-Fu: As demonstrated in the second OVA.
  • Waif-Fu: Justified because she regularly attends a gym school, where she learns self-defense techniques.


  • Boobs of Steel: Inverted, her bust size is noticeably larger than her sister's and most girls her age, and she is said to have taken the same martial arts classes and is as capable at it as Mairu, but Kururi isn't shown utilizing it like her sister.
  • Cat Smile: In the second OVA.
  • Combat Pragmatist: If she's ever in the middle of conflict, she has pepper spray handy.
  • Emotionless Girl: As the quiet twin, she's laconic and typically inexpressive.
  • A Handful for an Eye: Those who try to mess with her get pepper-sprayed in the eyes.
  • The Quiet One: She generally only talks when necessary and when she does, she only says what she needs to say. When she's in a chatroom, on the other hand...
  • Rapid-Fire Typing: Kururi's fast typing allows her to talk nearly non-stop online, at least until she hits the word limit.
  • Ship Tease: It's heavily hinted that she harbors a crush on Aoba.
  • The Stoic: Doesn't say very much, react very often, and tends to keep to herself.
  • Sugar-and-Ice Personality: She's inexpressive and quiet most of the time, yet she's affectionate and open to the people she's fond of, such as her sister and Aoba.
