Characters / Arakawa Under the Bridge

A list of characters from the anime and manga series Arakawa Under the Bridge, a series about an eccentric group of homeless people that have formed a community under a bridge on the Arakawa River.

Kou Ichinomiya a.k.a. Recruit

Played by: Hiroshi Kamiya (voice, anime), and Kento Hayashi (drama)

The main character. Rec is a straight-laced young man who is good at everything he tries, but also follows his family's mantra, "Never put yourself in debt to anyone" to the letter. Unfortunately, this is what lands him in the strange community of Arakawa's riverbank. He's a teacher in the river village.

  • The Ace: He is good at everything, but that also works against his favor in some ways. It is the result of his father's teachings under their family's mantra.
  • Berserk Button: He doesn't like when Hoshi refers to him as "Leech", especially once it started to catch out in the riverbank. The first time, he didn't take it well.
  • Bishōnen: Takes it Up to Eleven after completing Jacqueline's weight loss program.
  • Bookworm: He started reading technical books when he was just a baby. He is by far one of the most smartest members of the Arakawa's community.
  • Brainwashed and Crazy: In Episode 8 of Season 2, he was charmed by Amazoness's tengu henchmen to fall for her.
  • Butt Monkey: Since he is the Fish out of Water from the Arakawa's community, he is the only one who doesn't get their idiosyncrasies, and he is often made fun by them, because his normal-world's logic doesn't work for them.
  • Debt Detester: His family's mantra and principle is "Never put yourself in debt to anyone", so he always pays all debts as quickly as possible, except when he finds himself in a quandry when a venusian who lives under a bridge saves his life.
  • Embarrassing Nickname: Who would like to be known as "Recruit" (especially considering his job's position in his family's company)?
  • Fish out of Water: Rec is the only member of the Arakawa's village that applies "normal" logic to everything that happens there.
  • I Owe You My Life: He believes that this is what will happen if he becomes indebted to someone. Except, that is exactly what it happens when Nino saves him the first time they meet, becoming lovers as a result.
  • Iconic Item: His red tie that has the Ichinomiya family's mantra embroidered on it.
  • Kansai Regional Accent: Pops up when he becomes very angry.
  • Limited Wardrobe: He is always seen using a pair of suit's pants, a shirt and his red tie.
  • Loony Friends Improve Your Personality: Little by little, the more he stays on the Arakawa's riverbank, the better his own personality surfaces.
  • Masculine Girl, Feminine Boy: To some extent, he is the Feminine Boy to Nino's Masculine Girl. He is said to have the heart of a maiden, while Nino is more The Stoic, because she doesn't know how human girls are supposed to act.
  • Neat Freak: Rec is obsessed with cleaning his own living space.
  • Non-Idle Rich: The Ichinomiyas are practically rich, and he has a high position in their own company, however, and since the Mayor doesn't want any of his money (and Rec doesn't want to be seen as a "leech"), the best he could do is getting a job as a teacher for the younger members of the riverbank's community.
  • Not So Different: He sees Hoshi as a petty person, but when they team up, he is as petty as him.
  • Official Couple: With Nino. They are literally their respective "other halves".
  • One Head Taller: He is much taller than Nino.
  • Only Sane Man: And Up to Eleven, considering the type of place that is the Arakawa's riverbank village. Although, he can't really be seen as "sane" if you consider how far he would go to avoid debts.
  • "Well Done, Son!" Guy: This is how Rec sees his relationship with his father. Rec's motivation for keep doing as he tells him, is because he wants him to recognize his own merits, which he often doesn't. (So much that Takai sees himself as his dad's replacement... even to creepy degrees).


Played by: Maaya Sakamoto (voice, anime), and Mirei Kiritani (drama)

Rec's love interest and the reason he lives under the bridge. A Cloudcuckoolander who believes she's a Venusian (she is actually from Venus, as it is revealed later). She has a strange obsession with fishing some of the creatures that live in the riverbed and provides them for the community.

  • Ambiguously Human: Nino is presented to the readers and the viewers as someone who could be very human in appearance, unless you consider her unfamiliarity with what a normal human would do (especially a human girl) in a relationship, or the fact that she could breath under water.
  • Attention Deficit... Ooh, Shiny!: She has a short span of attention when things or situations do not interest her.
  • Berserk Button:
    • Listening to her most treasured tapes without permission makes her mad enough to climb a telephone pole.
    • Trying to take Rec from her, gets some interesting responses, too.
  • Cloudcuckoolander: That is unless you buy her Venusian story... which she actually is.
  • Expressive Hair: Her hair can act as an antenna for some weird reason.
  • Force Feeding: Her idea of hospitality around friends and her boyfriend, which is a Venusian trait.
  • Hair of Gold, Heart of Gold: She is a blonde, and her heart is too pure, considering that she is an stranger to normal topics as "relationships", or what is evil in the world. She can also sense when a person is evil or not.
  • Heroic B.S.O.D.: After Hoshi records her treasured "cosmic" tape with his song, and after the responsibility is turned against Rec, obviously.
  • Hidden Buxom: She is always seen wearing a tracker suit's jersey, so you can rarely see her big breasts.
  • Human Aliens: She is originally presented as an ambiguous human who claims to be from Venus, but actually her claims are true, as she was left behind by her Venusian parents, under the care of the Mayor.
  • Innocent Blue Eyes: She has a pure heart and soul, and her naïvety is often played with in the rest of the series.
  • Innocent Fanservice Girl: She used to take baths normally outdoors, but after a visit from the cops she began to use a Modesty Towel. It's later revealed that her Venusian's nature also makes her feel "natural" to be naked, as a distant memory of her race.
  • Manic Pixie Dream Girl: Nino fills this role for Ric, though her personality doesn't fit very well.
  • Masculine Girl, Feminine Boy: She is the Masculine Girl to Rec's Feminine Boy, to some extent, as she is unfamiliar with what a normal girl is likely to be in a relationship. That, and Rec is supposed to have a "heart of a maiden".
  • Megaton Punch: Is quite capable of taking out her anger on someone.
  • Mysterious Past: Her past and her "I'm a Venusian" claims are deliberately left out of focus earlier into the series. It's later revealed that she is really an alien, that she was left behind as some part of deal with the Mayor, and that Venusians are always fated to be with their "other halves" (they are always born in a pair of twins, and devote their love to each other, but since her twin died in Earth, she was left behind).
  • Official Couple: With Rec. They become their respective literal "other halves" at the end of the series.
  • Only Known by Their Nickname: Her name comes from the tag "Class 2-3" (Ni-no-san) on the tracker suit's jersey that she always wears.
  • Parental Abandonment: Her parents left her behind after her twin brother, her original "other half" died.
  • Selective Obliviousness: She ignores everything Hoshi throws her way, but if Rec does something romantic, she's touched. "If" she notices.
  • She Cleans Up Nicely: Just fit her any kind of feminine clothing, and she would look gorgeous under Rec (and Hoshi)'s eyes.
  • Single-Target Sexuality: Towards Rec, because not only she saved him from drowning at their first meeting, or because she wanted to be his girlfriend, it's because Rec is her "other half".
  • The Stoic: She is always under a expresionless face, rarely showing a smile. Unless she shares a moment with Rec.

The Mayor

Played by: Keiji Fujiwara (voice, anime), and Shun Oguri (drama)

The head of the Arakawa community. An odd man that constantly wears a kappa suit, he manages to corral and lead the members of the village with a good amount of (misguided) skill.

  • Chekhov's Gunman: Who could have guessed that a man who believes he is a kappa, is actually one of the main moving figures behind the whole plot of the series? And only for the sake of Nino and the secrets that lay under the Arakawa's riverbed...
  • Cloudcuckoolander: The Mayor claims he is a real kappa... but his rubber suit differs. And everyone buys the idea he is a mythical creature (even Rec, if only for a few minutes).
  • Crouching Moron, Hidden Badass: He is one of the most mysterious people that live on the Arakawa's riverbank, as he has saved many of the villagers' lives in his lifetime.
  • The Faceless: We never see his real face. Not even when he is doing an illusion-magic performance or when he is out of the kappa suit.
  • Full-Body Disguise: Despite his claims as a mythical creature, he is only wearing a disguise.
  • Line-of-Sight Name: This is how the Mayor names people once they become members of the community.
  • Obfuscating Stupidity: The Mayor has had moments of deep insight at times, belying the aloof nature he normally sports. This is also considering his "man behind the curtains" position, once he leaves the kappa suit out.
  • Oblivious to Love: Seemingly everyone knows that P-ko loves him but him. At the end, it's implied that they end up together, or at least, live with each other.
  • Papa Wolf: To Nino. Especially considering the kind of deal he had with Nino's parents, that end up with him taking care of her.
  • People in Rubber Suits: He is not a real kappa, just a man who is always seen using a rubber suit. Then, Hilarity Ensues when Rec is the only one who recognizes this.
  • Team Dad: He is the highest-positioned member of the Arakawa's community, and although he is always Obfuscating Stupidity, he is always going to support everyone in the riverbank.


Played by: Tomokazu Sugita (voice, anime), and Takayuki Yamada (drama)

A former famous musician who hit rock bottom and now lives under the bridge. He's always seen wearing his trademark star mask. He's also in love with Nino and always tries to make Rec look stupid in front of her. Under the bridge, he provides all the music for events.

  • Butt Monkey: Once Rec starts living in the riverbank, he gets on-par moments with him. He starts being the butt of the jokes once he finds out that Nino considers Rec as her boyfriend, but not him.
  • The Chew Toy: He ends up being put in a lot of painful situations.
  • Crazy Jealous Guy: Hoshi gets crazily jealous on Rec, just because of Nino. Although she barely even notices.
  • Dogged Nice Guy: Only to Nino. He has known her for a few couple of years, and it was "love at first sight", so he wanted to approach her little by little. But once Rec is mentioned as "Nino's boyfriend", he feels not only rejected, but attempts to be more spectacular to gain her attention (because he notices that there aren't advances in Rec and Nino's relationship).
  • Even Evil Has Standards: He can ruin Rec, even making him the end of the joke, just to get Nino's attention... and yes, he was initially on favor of Rec being hypnotized to "fall in love" with Amazoness... but, at the end, he helps him break out because he prefers to win Nino in his own power, and not with some unfair acts for both parties.
  • Expressive Mask: He wears two masks to cover his face. How it is even possible to make expressions on them is anyone's wonder...
  • The Faceless: We never see how is Hoshi under his mask, we only know from sketches and short appeareances of his real self, that he often wears sunglasses (due to his former stardom's status) and that he has wavy short hair.
  • Fun T-Shirt: Hoshi has some questionable fashion's tastes and he even does his own t-shirts, one noticeable being "ORE NO T-SHIRT" ("I'm a T-Shirt").
  • Hopeless Suitor: He is persistent to get Nino's attention, even after she mentions that she and Rec are a couple. No matter how many times he tries.
  • Jerkass: He acts as petty and as a Jerk Jock around Rec.
  • Karma Houdini: He messed up Nino's treasured tape and Rec gets blamed for it.
  • Moment Killer: Voluntarily (in front of Rec and Nino) and sometimes involuntarily.
  • Not So Different: Has more in common with Rec than you'd expect.
  • The Resenter: He is always going to be resentful towards Rec, and only because he "got the girl".
  • Secret Identity: Hoshi used to be a famous singer that even made it to the Oricon charts, but he lost his inspiration (his management never let him use his own songs) and became "Hoshi" to get away from everything.


Played by: Takehito Koyasu (voice, anime), and Yuu Shirota (drama)

A former soldier that became a man of the (wrong) cloth once he came to Arakawa. He constantly carries all manner of guns with him and clearly still holds a military mindset. He provides church services under the bridge.

  • A Father to His Men: He used to be in the military, and it is implied he was seen as such in his own squad (and that is also recurrent with the Arakawa's community).
  • High-Pressure Blood: When he isn't capable of taking Maria's insults, blood comes out from his face's scar.
  • Huge Guy, Tiny Girl: He is the tallest man of the Arakawa's community, so he is seen as a Huge Guy to every woman of the village, with noticeable exception to Amazoness.
  • Living Lie Detector: He was in the military, so he can easily react towards anyone who may be lying in front of him.
  • Love at First Punch: He met Maria in the middle of a battlefield when she used one of her attacks to leave him bald. He fell for her immediately.
  • Mad Bomber: Has an obsession of throwing grenades everywhere.
  • Nun Too Holy: He takes seriously his position as a nun, although he is a paranoid soldier who threats the Arakawa's community by the gun.
  • One-Man Army: He is huge, he has a military's past, and is well trained in the arts of camouflage and weaponry.
  • Only Known by Their Nickname: He is only known as "Sister", and nothing else more.
  • Perpetual Frowner: He rarely is seen with a smile on his face.
  • Person of Mass Destruction: He is, perhaps, the most dangerous person in the Arakawa's village.
  • Phenotype Stereotype: It's unclear from where exactly is Sister, although Stella's past (he directed her orphanage) suggests he may be English as well.
  • Scars Are Forever: Due to his High-Pressure Blood coming out from a scar that is across his face, it's evident that it frequently opens, and it will never heal.
  • The Stoic: He is a Perpetual Frowner who rarely express emotions... unless his crush's insults get to him.
  • Trigger Happy: Sister has been described as a "paranoid former soldier" by some of the villagers, so no one has to wonder why he points them out with guns in some "life-or-death" situations.
  • Wholesome Crossdresser: Sister uses a nun's habit (though his military suit is below it) almost all the time, but there are ocassions (either in Imagine Spots or acting scenes) he will use other feminine clothes such as a schoolgirl outfit, complete with a barette.


Played by: Chiwa Saito (voice, anime), and Eri Tokunaga (drama)

A young girl from England who was raised by Sister in an orphanage. She has a noticeable crush on him and appears sweet in general, but she is actually highly skilled in martial arts and is rather accomplished in several underworld trades. She can also transform herself into a musclebound man three times her size thanks to Sister's training. She serves as a yakuza boss for the community.

  • Age Lift: In the drama, Stella is portrayed as a teenager (a bit older than the Iron Brothers) instead of a child.
  • Clingy Jealous Girl: She doesn't take it well when she finds out about Sister's feelings for Maria. She changes her mind at the end, as she sees Sister and Maria as part of her "family".
  • Deliberately Cute Child: She is firstly presented as an innocent child (even Rec falls for it)... but she is actually a Cute Bruiser.
  • Limited Wardrobe: She is mostly seen wearing a cutesy feminine dress, with some obvious exceptions (she also uses pajamas). Her drama counterpart is seen wearing a variety mix of clothes one over the other.
  • Precocious Crush: She is implied to have a crush on Sister, because he took care of her when she was younger, although it seems that she changes her opinion once the series is ending.
  • Yandere: Towards Sister.


Played by: Miyuki Sawashiro (voice, anime), and Nana Katase (drama)

A former spy who came to live under the bridge. A sadist at heart, she delights in emasculating every man in the community, especially Sister, with whom she has a history. She runs a sheep farm for the community.

  • Berserk Button: It's implied that she and Sister were former lovers, and every time Sister slips his tongue into his military's memories, she would attack him with a pair of scissors, from across the riverbank.
  • The Bully: As the sadist that she is, she likes to insult the many men around the community (with exception of the Mayor), although her biggest victim is Sister.
  • I Shall Taunt You: Her addiction is insulting every man of the village, until their spirit to continue living, dies as well.
  • Not a Morning Person: She can become a "monster" when she is woke up earlier.
  • Pet the Dog: Her treatment of Stella after their "duel".
  • Rose-Haired Sweetie: The Bitch in Sheep's Clothing variant — she's only sweet at first glance. She's actually a sadist who loves to bully others. She can be nice to the girls, though.
  • Shear Menace: Maria threats others with her scissors.
  • The Sociopath: Comedic Sociopathy at most, but in the episode 7 of season 2 she actually goes insane while locked for several days with the people she feels she shouldn't be bullying (ie. girls).
  • You Gotta Have Blue Hair: Her hair is pink, which stands out since everyone else in the cast has realistic hair colors.

The Iron Brothers (Tetsuo and Tetsuro)

Played by: As Tetsuo, Yuko Sanpei (voice, anime), and Takuto Sueoka (drama). As Tetsuro, Ryoko Shintani (voice, anime), and Raito Mashiko (drama)

A pair of brothers always seen wearing iron helmets. They claim to have been experimented on and have psychic powers, which are only kept in check by the helmets. They are very lively and run an oil drum bathhouse under the bridge.

  • Deliberately Cute Children: They are a pair of cute children who always do things together. They sometimes mean no harm to others, unless they are obeying Stella's orders.
  • Expressive Masks: They do not take their masks out, so instead, these always express their emotions. This is, however, subverted in the drama, since they look more as tin-luchador masks.
  • The Faceless: Their faces, in a similar case as the Mayor's and Hoshi's, are obscured when they describe their past. This is also played in the cover of the 13th volume of the manga.
  • Hulking Out: Given the circumstances of training with Sister... just like Stella. They only spend transformed for a while.
  • Mr. Imagination: Rec considers that the Iron Brothers are actually "chuunibyou" if they aren't what they claim to be.
  • Power Limiter: Their masks control their psychic powers, gravity and also shut down the Government's GPS. Or so they claim.
  • Psychic Powers: They claim that they have such, but they are never shown in the whole series. Of course, who would tempt them to use them if they are paranoid of the government and according to them, their powers are too powerful.
  • Puppy Love: One of the twins is in love with Stella.
  • Theme Twin Naming: They are the Tetsujin Brothers, Tetsuo and Tetsuro.

Toru "Shiro" Shirai

Played by: Hochu Otsuka (voice, anime), and Toru Tezuka (drama)

A former salaryman who now lives under the bridge. He can't go anywhere unless he's able to walk on a white line, so he always walks with a field striper.

  • Nice Guy: He is one of the nicest guys you will ever find in the series.
  • Oblivious to Love: He doesn't recognize that Shimazaki loves him with fervor.
  • Salaryman: What his former job was, later, he instead wants to become the most recognizable "white lining walker" in the entire world.
  • Super OCD: He believes that, if he walks out off his white line, his wife and children would become chicken. And since no one can prove him otherwise, the rest of the community don't want to risk it.
  • Smarter Than You Look: Despite his looks, or the fact that he was a failure as a salaryman, he is actually one of the smartest members of the community. He even is in charge of a "Change your job" fair inside the Arakawa's community.


Played by: Chiaki Omigawa (voice, anime), and Natsumi Abe (drama)

A young woman who lives under the bridge during the growing season. While cute, she's horribly clumsy. She has an unrequited love in the Mayor. She runs a vegetable farm for the community.

Played by: Cho (voice, anime), and Kazuyuki Asano (drama)

Rec's assistant from his company. He came searching for Rec when he never came back to the office. He is steadfastly loyal to his boss, but also has a very unhealthy obsession with him. He oversees the running of Rec's company in his absence and helps Kou with his projects under the bridge.

  • Brainwashed and Crazy: He got stuck with Rec in their trip to Venus, it's just that he was eaten by a rabbit-like monster (and this brought sequels to Rec once he came back to Earth).

  • Megane: He is always seen using glasses.
  • Papa Wolf: He is very protective of Rec, ever since he considered himself as his dad's replacement.
  • Straight Gay: He only acts feminine when he is preparing food or other home made stuff for Rec. It's up to interpretation if he does so because he sees him as his son, or because he wants Rec to see him as a potential lover.
  • Subordinate Excuse: Despite his weird attraction to Rec, he sometimes is useful.


Played by: Rie Tanaka (voice, anime) and Waka Inoue (drama)

  • Beauty Mark: She has a mole under her left eye.
  • Brainwashed: She is rather known as the "Queen of the Brainwashed", because she gets brainwashed so easily.
    • The first time is when she just suffered a Heroic B.S.O.D., after finding out that Shiro actually has a family and that he hasn't got divorced from his wife. To make matters worse, she is contacted by a Mole who was willing to know and reveal the secrets of the Arakawa's riverbed. Then, she becomes The Mole for him.
    • The second time is when she gets easily convinced by a fortune teller. However, she gets really useful when Rec was looking for Nino in the last arc of the manga.
  • Enigmatic Minion: Under the Arakawa's community, she becomes The Mole for Rec's dad, since she is more loyal to him than Rec himself. The Mayor then threatens her to not keeping with the research about the riverbank or Nino. She is later convinced by the same Nino to keep living there with the rest of the community.
  • The Mole: Her basic role to obtain information about the Arakawa's riverbed and Nino. Once under Rec's father, and another under the Mole's guidance.
  • Single Woman Seeks Good Man: After going to the bridge for the first time, she falls at first sight for Shiro after he helps her to get out of Sister and Maria's trap. Admittedly there was a bit of Comically Missing the Point involved, too.

Seki Ichinomiya

Played by: Rikiya Koyama (voice, anime), and Takaya Kamikawa (drama)

Rec's father and CEO of one of the most powerful companies in the city, if not Japan. He firmly believes in never being indebted to anyone and has instilled that in Rec, for his entire life. A cutthroat businessman, he gets what he wants when he wants it and proudly stands tall over his accomplishments.

  • Disappeared Dad: He had a rare presence in Rec's life (he would rarely eat with him in the table and such), while the "dad" role went to Takai, one of his assistants. It's suggested that perhaps he feels resenful over his wife's death, so he maintains a distance from his son.
  • Four Eyes, Zero Soul: Subverted. He's very harsh and curt with Rec, but he does have some love for his son.
  • Humiliation Conga: In a situation that briefly parallels to his own son's first encounter in the Arakawa's bridge, he leaves all classy and looking so cool he annoys the policeman.

Once a master hairdresser and attractive man, he got sick and tired of his lifestyle and ran away with little more than a katana from his family's house. After an accidental meeting with the Mayor under the bridge, his "samurai spirit" was awakened, and now he speaks in an older Japanese dialect and wears a topknot as he lives with the community by the Arakawa river. He still uses that same katana to cut the hair of the Arakawa people.

  • Everything's Better with Samurai: He is considered as the "last" one of them, obviously. He is also a fan of Ryouma Sakamoto he also writes a blog under this identity.

Played by: Fumihiko Tachiki (voice, anime), and Norihisa Hiranuma (drama)

Rumored to have once been the boss of a Yakuza-like gang of bird-headed people, and supposedly betrayed their trust when he fell in love and eloped with the bee princess Jacqueline. It's debatable how much of that story is true, but what is known is that he is deeply in love with her.

  • Always Save the Girl: As long as the girl is Jacqueline, he is always going to be there for her.
  • Even the Guys Want Him: Or, at least, they cannot help swooning over his manliness in Rec and Hoshi's cases.

  • Rated M for Manly: He is the manliest of all men in not only Arakawa's riverbank, but also in Japan.

  • Single-Target Sexuality: He has no eyes for other woman, except for Jacqueline.

A woman in a bee costume who fell madly in love with Billy and is practically inseparable from him. She runs a day spa called "Queen Bee" under the bridge.

Captain a.k.a. "Potachi"

Played by: Tomokazu Seki (voice, anime)

A mangaka who publishes his works under the pen name "Potato-chip Kuwabara." A total sci-fi geek who likes to think of himself as a space captain defending the Earth from aliens.

  • Captain Space, Defender of Earth!: He believes that his real role in the world is that he should protect the world from evil venusians, and his way to warn the world about it is through his sci-fi manga's pages. He believes Nino is an alien-princess that would destroy the world.
  • Creator Breakdown: In-Universe. He ran away from his career as a mangaka when his editor kept forcing him to draw Moe manga instead of sci-fi.
  • The Mole: His own desire to defend the Earth is what the Mole's organization wanted to use in their own benefit. Although, he still has some affection to the Arakawa's community. He is self-aware that the Mole is full of "bad" people, but his only motivation to keep doing so was because he just wanted to keep playing as a hero, no matter what side he takes.


Played by: Yuu Kobayashi (voice, anime)

A mysterious Amazon woman who lives down the river, outside the riverbank's community. Her personality constantly shifts from that of an intimidating warrior to a high school girl. She's rarely seen without her cell phone and has a love of all things made in Saitama. She works for an unknown person and is often accompanied by a trio of "tengu" (guys with tengu masks and bikini tops worn over their t-shirts) who act like her "big brothers".

  • Amazonian Beauty: Has the body of an Amazon, but the heart of a high school girl.
  • Hopeless Suitor: She thinks she is this to Hoshi.
  • No Guy Wants an Amazon: This is what she believes, because she is too forceful onto the guys she likes. Her "brothers" seem to think otherwise, though.
  • She Cleans Up Nicely: Without the heavy make up, and despite the Amazonian-body and disguise, she can look really pretty and very normal, just like a high school girl. However, she gets easily too embarrassed by it.
  • Stripperiffic: Her outfit goes along with the Amazon warrior theme, but it leaves very little to the imagination.
  • Tiny Guy, Huge Girl: To Rec. And Hoshi.
  • Tsundere: Lampshaded by Rec and it's as creepy as it sounds.
  • Uncanny Valley Makeup: Her make up looks straight from a "horror" movie.
  • Valley Girl: What her Saitama dialect is often translated as.

The Tengu Brothers

Played by: Yuuichi Nakamura (voices, anime)

The trio of "tengu" that live with Amazoness in the south part of the Arakawa's riverbank. They consider themselves as her "older brothers", as they often worry about her, especially in love matters.
