    Schoolgirl Trio 

Yuuko "Yukko" Aioi

One of the five "main" characters of the series, "Yukko" is an ordinary student with a propensity for forgetting her homework. She is also locked in a perpetual "Boke and Tsukkomi" gag with Mai.

  • Berserk Button: She can only take being called stupid so much before she snaps.
  • Book Dumb: Not as substantial as other cases, but she does have to borrow homework from Mio on a regular basis.
  • Breath Weapon/Wave Motion Gun: When in enough pain, her screams let out those. One of them even pierced through all the planets of the solar system (And Pluto)!
  • Butt Monkey: The entire universe is apparently out to get her.
  • Cannot Tell a Joke: She's Giftedly Bad at it.
  • Cool Big Sis: Earns this right with Professor.
  • Face Palm: One evening, as she just got better from a cold, she remembers that she has two exams the next day. She tries to focus on English, but gets lost in her thoughts and ends up writing a poem. She promptly face palms after she realizes it.
  • Genki Girl: Although she is certainly genki, she also plays it up sometimes to hide embarrassment.
  • Goal in Life: Has twice now been shown to have no decided goal yet.
  • Gratuitous English: A serial offender.
  • Hidden Depths: She's a damn good poet.
  • Imagine Spot: Frequently daydreams in class about far-fetched scenariosnote  explaining how Mio got her hair-ties, and her twin tails, and her very person.
  • The Jinx: Inverted, if Episode 26 is any indication. She's apparently sort of a karma sink. She herself is jinxed, but spreads good fortune to everyone around her.
  • Minor Injury Overreaction: See Wave Motion Gun below.
  • Oh Crap: When she realized that she may have pissed off Mio.
  • Pungeon Master: She tries, anyway.
  • Standing in the Hall: Often
  • Straight Man: Occasionally, if Mio is acting up or playing sports, or if Mai is in "Boke" mode.

Mio Naganohara

Don't ask how the Hair Decorations stay there. No one knows the answer to that one.
Voiced by: Mai Aizawa

"If she sees that drawing, she'll never think of me the same way again!"

Another of the five "main" characters, Mio is the most normal of the cast, but that isn't saying much. She usually plays the straight man to Yukko's antics.

  • Badass Adorable/Cute Bruiser: This adorable, very nice young girl is more than capable of kicking your ass seven ways to Sunday if you accidentally piss her off too much.
  • Berserk Button: She's normally very nice, but if you ever mess with her food, even by accident or if you expose her Yaoi drawings, get the fuck out of there and head for the hills!
  • Beware the Nice Ones: See above.
  • Breath Weapon/Wave Motion Gun: When in enough pain, her screams let out those.
  • Covert Pervert: To the extent that she beat up Yukko, a police officer, an old man, and a goat all in the name of preventing people from finding out she draws Yaoi.
  • Everything Is Better With Spinning: Hit Yoshino with a corkscrew and attacked Yukko and Sasahara's goat with a Dragon Screw.
  • Flash Step: During her Unstoppable Rage, she pulls off a Ashura Senkuu before dragon screwing Sasahara's goat.
  • Girlish Pigtails: Held together by wooden cubes which, according to Yukko's daydreams, are magical artefacts that fell on her head from a zeppelin.
  • Gretzky Has the Ball: An in-universe example, she can't play sports to save her life. She used to practice Kendo and is quite adept in shadow-boxing and wrestling apparently, implying her problem is with non-combat sports.
  • Hair Decorations: Wears two wooden cubes in her hair. And aside from being kind of an odd choice for hair decorations, they're completely ordinary. Or are they?
  • Hair-Trigger Temper: Around Yukko and Yoshino (though granted, the former is a bit of an idiot, and the latter is The Gadfly).
  • Imagine Spot: At one point created an entire romantic scenario between Nano & Sasahara when Yuuko convinced her they were a couple.
  • Iwo Jima Pose: Making small talk with Sasahara is momentous enough to merit a pose of a whole bunch of Mios raising a Sasahara flag!
  • Laughing Mad: When she, Yuuko and Mai are stuck in an elevator. After Mio says "Eggplant", she and Yuuko break down into mad laughter over this, the fact that they're not getting any help any time soon, and the fact that Mai appears to have died. Laughing mad indeed.
  • Lost Food Grievance: Don't mess with her food or bad things will happen.
  • Love Hurts: After seeing Misato "escorting" Sasahara, she goes into Heroic BSOD.
  • My Life Flashed Before My Eyes: When she tastes her sister's kusaya (salted, sun-dried mackerel) jam the second time.
  • Power Palms: During her fight vs the green mooks.
  • Serious Business: Her food and her Yaoi.
  • Straight Man: Most frequently of the cast.
  • Wrestler in All of Us: Her preferred method of knocking out people is wrestling moves, like the Dragon Screw.

Mai Minakami

Don't take what she says at face value.

Rounding off the Power Trio with Yukko and Mio is Mai, a quiet bespectacled girl with a fondness for screwing with people just to see how they'll respond. Makes up the "Boke" side of her relationship with Yukko. Also has a thing for whittled Buddha statues.

     Shinonome Laboratories 

Nano Shinonome

Voiced by: Shizuka Furuya
Sure, it's weird she's a robot, but look at everyone else.

A Ridiculously Human Robot who wishes she were a real girl more than anything, even if it means things like being able to get dental cavities. She struggles to keep the fact that she's a robot a secret. A struggle not at all helped by the obvious wind-up key in her back which her creator absolutely refuses to remove.


The creator of Nano. Hard to believe, right?
Voiced by: Hiromi Konno

Nano's eight-year-old creator. Aside from her ability to build incredibly advanced machines, she's a completely normal kid. Likes sharks.


"No matter how you look at it, that was too much petting."
Voiced by: Minoru Shiraishi

A black cat living with Nano and the Professor. He is able to talk due to a scarf the Professor created. He was originally Nakamura-sensei's cat, named Taisho.


Koujirou Sasahara

A spacy student who wears an ascot at all times and rides a goat to school. He puts on pretensions of being the eldest son of a wealthy family. However, it's quickly revealed he's the eldest son of a family of farmers (hence the goat). He tends to irritate his classmate Misato Tachibana with his oblivious nature, causing her to frequently shoot at him. Don't worry, he can take it.

Misato Tachibana

The lengths she'll go to in order to deny her love for Koji—*boom*
Voiced by: Chika Horikawa

A high school girl who frequently finds herself angered by the oblivious carefree actions of Sasahara. She expresses her frustration by unleashing an escalating arsenal of weapons ranging from revolvers to missile launchers. There are subtle hints that these outbursts may be the result of feelings for Sasahara on Misato's part.

Tsuyoshi Nakanojou

Looks can be deceiving.

A boy whose most prominent feature is a naturally growing mohawk. When not at school, he is a skeptic and seeks to debunk supernatural phenomena. Despite his mohawk making him look like a delinquent, he actually is a fairly nice guy.

Haruna Annaka

This is pretty much Annaka's default expression.
Voiced by: Kaori Sadohara

A girl noted for her very large red ribbon that she wears in her hair. She's fond of trying out new places that she reads about, but tends to find the experiences more confusing than enlightening.

Kenzaburou Daiku

Voiced by: Ryouta Yoshizaki

Son of the C.E.O. of the Daiku Corporation, which runs chains of restaurants and cafes among other things. Created the "Go-Soccer" Club on a whim and has since come to regret it since encountering people actually familiar with the game.

  • Club Stub: With Sekiguchi, at least untill it turned out there was such a thing as Go-Soccer.
  • Only Sane Man: In comparison to most of the cast, especially in comparison to 3/5ths of the Go-Soccer Club.

Yuria Sekiguchi

Voiced by: Ai Hirosaka

For a while she was the only member of the Go-Soccer Club alongside Daiku. However, she shows little interest in anything beyond reading the latest volumes of Helvetica Standard.

Makoto Sakurai

Voiced by: Takahiro Hikami

The younger brother of teacher Izumi Sakurai. He was surprised to learn his school had an Go-Soccer club and eagerly joined. To Daiku's shock, however, Makoto takes his Go-Soccer very seriously.


Voiced by: Kouta Yamaguchi

A student with an afro. Appears more often in the background than as a speaking character.

  • Funny Afro: His defining trait

Voiced by: Youko Tamaoki

One of Misato's friends. She is attracted to Nakanojou.


Voiced by: Yumi Higuchi

One of Misato's best friends. A bit of a ditz.

  • Butt Monkey: Not quite on Yuuko and Sakamoto's level, but still.
  • The Pollyanna: Attempted to be one in one episode. A combination of bad luck and clumsiness quickly put an end to that.

Mihoshi Tachibana

Voiced by: Manami Honda

Misato's younger sister. She's in middle school and is a member of the kendo club. Her response to the absurdities that surround her is barely contained laughter. She's fully aware of Misato's feelings for Sasahara.

  • The Resenter: Towards 'that damned genius' Yoshino Naganohara regarding her kendo skill.

A member of the Go-Soccer club, and one of the few people who are actually familiar with the rules of the game.


Izumi Sakurai

Voiced by: Mami Kosuge

A timid teacher who became a guidance counselor as much to improve herself as her students. She tends to get flustered very easily, and has a hard time actually disciplining students. The elder sister of Makoto Sakurai.

  • Adorkable: Mainly due to being a Shrinking Violet.
  • Apologizes a Lot: She's so shy that she will often apologize for no reason when talking to people.
  • Covert Pervert: Played with in Episode 23: after she discovers a porn magazine in her brother's room, she decides to take a peek to see if it is, and blushes even more than usual.
  • Girlish Pigtails: On her day off in Episode 21.
  • Nice Girl: She and Nano are quite possibly the nicest characters in the manga.
  • Sensei-chan: She's quite easy to mistake for a student before she is formally introduced.

Manabu Takasaki

Voiced by: Tetsu Inada

A teacher at the high school. Frequently on Yuuko's case regarding her inability to do her homework. He harbors a crush on Izumi Sakurai. His imagination tends to run wild when he's speaking to her. He's also sponsor for the Go-Soccer Club, blackmailed by Makoto.

  • Cannot Spit It Out: To Izumi. Everytime he tries to even talk to her, he quickly turns into a stuttering mess.

Kana Nakamura

Voiced by: Kaoru Mizuhara

A science teacher who managed to figure out that Nano's a robot. Confused about why Nano would be enrolled in school instead of announced to the world, she has made it a point to capture Nano and study her. Her schemes always end up backfiring.


Voiced by: Yuichi Nagashima (a.k.a. Cho)

The school principal who often tells old jokes that no one gets. He has also suplexed a deer.

  • Cannot Tell a Joke: Though unlike Yuuko's which are plain terrible, his jokes are simply way outdated.
  • Crazy-Prepared: Wore a bullet-proof vest when trying to catch a deer.
  • Dodgy Toupee: It's more prone to wobbling around to and fro (and sometimes fall off altogether) than staying in place.
  • Epic Fail: He tries to moonsault during his "fight" with a deer. He fails miserably and lands face first on the ground.

Vice Principal

  • Big Sister Bully: To Mio, who responds with violence.

Nakanojou, Sr., the Daifuku Guy

Voiced by: Hirokazu Hiramatsu

Runs a daifuku stall on the streets of town. He takes selling Daifuku very seriously, and insists on model behavior from the people he hires to be his daifuku mascots. Like his son, he has a natural mohawk. Though his has grown long enough that he can fake a normal hairstyle with it.


Voiced by: Kaoru Mizuhara

The Vice Principal's grandson. The Vice Principal anticipates his visits, but Micchan always ends up doing something to horrify his grandpa, such as trying to get him to eat mudpies.

  • Chekhov's Gunman: You can see him making said mudpies in the background of the nagashi somen scene.


Voiced by: Daisuke Ono

A random crow that the Professor brings home. She puts Sakamoto's scarf on it so it can speak.

Biscuit #2

Voiced by: Etsuko Kozakura

A robot made by the Professor. He runs on biscuits. An improvement over Biscuit #1, whose head flew off.

  • The Unfavorite: He was only made to impress Nano, so he gets neglected often.

Voiced by: Takaya Hashi

An officer in the Fey Kingdom's army, adopted and raised by King Albert. Despite his grand plans, his attempt at rebellion ultimately fails due to his own clumsiness.

  • Death by Falling Over: "His attempt at rebellion ultimately fails due to his own clumsiness" is not an exaggeration.

The Mooks

Voiced by: Hochu Otsuka (#8), Jun Fukuyama (#66), Joji Nakata (#22), Akio Ohtsuka (The Negotiatior)

The men who serve the king and princess on the Fey Kingdom Zeppelin. They wear identical uniforms of slacks with green jackets and caps, and are distinguished by the numbers on their hats. Number Eight is usually the centerpiece in skits featuring the zeppelin.

    • Mauve Shirt: Number 8. Case in point, he's the only mook to take on Mio and live.
  • You Are Number Six: The only way to distinguish individual mooks is by the number on their hats or, in the case of ranked or nicknamed members, the kanji. They refer to themselves by their numbers, too.

     Helvetica Standard
