    Schoolgirl Trio 

Yuuko "Yukko" Aioi
Voiced by: Mariko Honda

"I should be glad nothing perishable landed on me!"

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.

  • Abusive Parents: Downplayed and Played for Laughs, but her mother isn't above Dope Slapping her, and doesn't seem to believe her daughter is too smart.
  • 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 these. 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 the Professor. The Professor adores her and, in a manga chapter, Yukko proves capable of resisting the Professor's tantrums, even if only by being more nonsensical. In a Time Skip chapter, an adolescent Professor becomes ecstatic upon hearing Yukko's coming back to Japan.
  • Easily Impressed:
    • She's dazzled out of her wits when she learns that Nano is actually a robot and becomes enraptured by everything Professor makes her do as if she were a little kid. Even the simple act of pouring a cup of tea out of Nano's removable wrist.
    • In the manga, she's incredibly impressed when she learns Sakamoto can talk. Being Yuuko, she then decides that the best thing to do is to... ask him to shake her hand with his paw. Every time Sakamoto says something, Yuuko is incredibly impressed.
  • 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.
  • Global Ignorance: In a series of flashbacks in the manga detailing how Mai and Yukko first met, we find out that Mai actually moved to Japan a little over a year ago, and is actually from Alaska. Mai sits down next to Yukko, who asks Mai which part of Japan Alaska is in.
  • 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. Mogami River...
  • Imagine Spot: Frequently daydreams in class about far-fetched scenariosnote  explaining how Mio got her hair-ties, 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 Breath Weapon above.
  • Motif: Watermelons. Her favourite kind of soda is melon flavoured, she attempts to reinvent her image by wearing a pair of watermelon clip-ons in her hair, and one segment involved her eating melon bread, realising that she ate the expiration date, and then nervously chewing.
  • Oh, Crap!: When she realises 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.

  • 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.
Voiced by: Misuzu Togashi

"I was joking."

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 Kouji—*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.

  • Animal Motifs: Rabbits. Her hair ribbon gives the appearance of rabbit ears and most of her character song is her saying "pyon" (an onomatopoeia for a rabbit jumping).
  • Big "WHAT?!": See Catch Phrase.
  • Catch Phrase:
  • Expy: Looks very similar to Tsukasa Hiiragi, to the point that her animation model may just be Tsukasa's model tweaked to fit the series' art style (both Lucky Star and Nichijou were both animated by Kyoto Animation, so this isn't far-fetched).
  • Hair Decorations: Her Oversized ribbon.
  • Only Sane Man: The humor in her sketches comes from her reactions to the insanity that unfolds around her.

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 until it turned out there actually was such a thing as Go-Soccer.

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.

  • Black Bead Eyes: To emphasize her detachment from her surroundings.
  • Cannot Spit It Out: To Daiku.
  • Club Stub: With Daiku, at least until it turned out there was such a thing as Go-Soccer.
  • Emotionless Girl: Not to Mai's extent, as she's slightly more prone to showing expressions, but she's still emotionless most of the time.

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
  • Hammerspace Hair: In one gag he is seen pulling out numerous things from his Afro including Sakurai-sensei's favourite treat.

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.
  • Genki Girl: Not to the extent of other examples of the trope, but she is nonetheless energetic.
  • Only Known by Their Nickname: Neither her first name or her given name are mentioned at any point.
  • 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.

  • Bratty Half-Pint: She can barely contain laughter when someone embarasses themselves, and likes to tease her sister every now and then about her feelings for Sasahara.
  • The Resenter: Towards 'that damned genius' Yoshino Naganohara regarding her kendo skill.


Voiced by: Ryouta Takeuchi

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.
  • 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.
  • Shrinking Violet: Unless she's around her younger brother.
  • Tears of Joy: She wipes at her eyes when Yuuko says that she wants to be a teacher just like her in episode 23.
  • Terrible Artist: Her drawings tend to look more like cute and childish versions of whatever they're supposed to represent. And much to Mio's dismay, she also tends to consider Yuuko's drawings "cool".

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.

  • Big "WHAT?!": Occasionally goes back and forth in an "Eeeehhhh?!" exchange with Annaka.
  • Cannot Spit It Out: To Izumi. Everytime he tries to even talk to her, he quickly turns into a stuttering mess.
  • Covert Pervert: He does a mostly good job hiding his crush on Izumi from most people. Though his Large Ham tendencies sometimes weird the crap out of bystanders, they just assume he's wacky and think little else of it. Too bad for him though, Izumi's brother busted him.
  • Freudian Slip: When trying to act cool with Izumi he flat out asks her if she has a boyfriend. When he later tries to talk to Makoto, Izumi's younger brother, he asks him the same thing. Both instances end predictably.
  • Gratuitous English: Prone to bursting into it when he messes up.

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. Also, despite what you might initially expect, that's it he's wearing there in the picture to the right! It covers only the sides and back of his head while still leaving the top bald.
  • Epic Fail: He tries to moonsault during his "fight" with a deer. He fails miserably and lands face first on the ground.

Vice Principal
Voiced by: Hiroshi Naka

The Vice Principal of the high school. His sad life is brightened by visits from his little grandson Micchan... until Micchan does something that leaves him sadder than before. Seems to dislike the Principal.


Yoshino Naganohara
Voiced by: Motoko Kobayashi

Mio's elder sister. An immature young woman fond of playing pranks on people she comes across, especially her sister. She attends college and is skilled at kendo.

  • Big Sister Bully: Downplayed example to Mio; Yoshino's pranks are far from malicious, but they do annoy the crap out of her sister, who responds with violence.
  • The Gadfly: Especially, though not exclusively, towards her sister.
  • Genius Ditz: In kendo, at least, as Misato and Mihoshi think. According to the latter, Yoshino claims training in kendo makes her weaker.


A girl who works at the Daiku Cafe. She's very timid and has a hard time explaining things when her customers are angry or flustered.

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.


A dog who has sometimes appeared before Yuuko to offer a comforting paw when things are especially rough on the girl. Is sometimes accompanied by a puppy, Kobuddy.

Hajime Sakurai

Izumi and Makoto's dad. He's a respected writer, but very sleepy all the time. His editor attributes this to Hajime losing his wife at a younger age, and thus having to deal with writing and housework at the same time. As he first appeared in chapter 142, he doesn't get to make an appearance in the anime.

  • Children Raise You: His kids sometimes have to look after him, due to him being so sleepy.
  • Cloud Cuckoo Lander: A mild example, but he's so sleepy that he sometimes fall into this; he once tried to light his cigarette instead of his lighter.
  • Sleepyhead: Due to being overworked.

     The Fey Kingdom 
A king, princess, and their soldiers who fly high above the world in a zeppelin. Their adventures are really just elaborate dreams on Yuuko's part. Or are they?

King Albert

Voiced by: Tamio Ohki

Ruler of the Fey Kingdom. He decided to take a trip around the world on a zeppelin, providing Dolph the chance he needed to grab power. He carries one of the two wood cubes which can be used to resurrect an ancient weapon.

Princess Starla
Voiced by: Noriko Hidaka

Princess of the Fey Kingdom. She holds the second wood cube needed to resurrect an ancient weapon. She manages to keep it hidden from Dolph until his rebellion fails. She holds the Mooks' turning on her and her father against them.

  • Bad Boss: Justifiably so, considering the Mooks helped Dolph in his attempt to usurp the royal family, but Starla gets exceptionally cruel with her management of them.
  • Pointy Ears: Same as her father.
  • Trap Door: She has the Mooks try to entertain her in one sketch. This is the penalty when they fail.
  • Trash Talk: Dolph describes her speech as vulgar, contradictory to her appearance.
  • You Have Failed To Entertain Me: Drops her henchmen via Trap Door when they fail to entertain her.


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.

  • Big Bad Wannabe: Dolph's after the keys to a superweapon that could give him the power to rule the world, he successfully executes a plan to capture the king and princess, and he has an airship loaded with henchmen at his beck and call. Then he abruptly trips over his own feet and dies, and his army surrenders to the princess on the spot.
  • Death by Falling Over: "His attempt at rebellion ultimately fails due to his own clumsiness" is not an exaggeration.
  • Expy: Dolph is a crazed, power-hungry army officer in a world of airships, he's obsessed with his supposed "right" to an ancient Magitek superpower, and he's after a MacGuffin associated with the royal family. Sounds very similar to Colonel Muska.

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.

  • Redshirt Army: Well, Green Jacket, that is.
    • Mauve Shirt: Number 8. Case in point, he's the only mook to take on Mio and live.
  • You Are Number 6: 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 

A manga often seen being read by characters, as well as an actual manga by Keiichi Arawi. Some episodes have Helvetica Standard segments of their own.

With the exception of Pino, none of these names are "official", merely descriptive. Character entries are reserved for characters who have appeared in more than one Helvetica Standard sketch.

The Clueless Shinigami

A Shinigami who doesn't understand how to read the atmosphere of a situation. Once had his scythe stolen by the Poverty-Stricken Tengu.

  • I Do Not Speak Non Verbal: The first Helvetica Standard skit has him asking what "KY"note  refers to. His captain answers "You."
  • Shinigami: Though he more closely resembles The Grim Reaper.


An angel. Tries to help others when she can and owns a very powerful toaster.

The Landlady

A kind landlady who isn't so kind to tenants who are behind on rent.

Poverty-Stricken Tengu

A Tengu who has sometimes resorted to theft to get enough money to eat.
