Schoolgirl Trio

    In General 
  • Tender Tomboyishness, Foul Femininity: The trio has some of this going on. Yukko rarely messes with anyone on purpose, being a by-and-by nice Genki Girl who's left to react to a lot of madcap antics (seen in how sweetly she reacts to an alleged love confession by a female friend, despite not being ready to hear it). Her feminine-looking and quiet friend Mai, on the other hand, takes a Troll to the next level, especially around Yukko, and likewise, their feminine-looking friend Mio will go all out pulling brutal wrestler moves on people and animals that upset her.

    Yuuko "Yukko" Aioi

Voiced by: Mariko Honda (Japanese), Morgan Garrett (English)

"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 seems to believe her daughter isn't very smart.
  • Ambiguously Gay: Nothing in Yukko's response to Mai's "confession" says that she isn't receptive to going out with a girl, only that she's either blindsided by the confession or not ready to date.
  • 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: Played for Laughs, but she can shoot beams out of her mouth when in enough pain.
  • Butt-Monkey: The entire universe is apparently out to get her.
  • Cannot Tell a Joke: She's Giftedly Bad at it.
  • Celebrity Resemblance: Yuuko is once mistaken for the famous author Doublecheeseburgirl by two middle-schoolers. When we actually see the author in Chapter 148, she's pretty much Yuuko down to the hairstyle and choice of hoodie, but with a chiseled and exhausted face.
  • 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.
  • Costume Evolution: The final chapter shows her having really reinvented her style over the Time Skip abroad.
  • Dumbass Has a Point: She deduces that Nano is a robot simply because she has a Wind-Up Key on her back. Mio (who doesn't seem to understand what kind of manga this is) points out that not only is this flimsy reasoning, but that Nano is clearly distressed when people think that she's a robot, and that Yukko should stop before she hurts Nano's feelings.
  • Easily Impressed:
    • She's dazzled out of her wits when she learns that Nano is actually a robot and becomes enraptured by everything the 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, after she's 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: Is twice shown to have no decided goal yet.
  • Gratuitous English: A serial offender.
  • Hidden Depths: She's a damn good poet. Mogami River...
    • In Episode 23 we get a brief glimpse of her Future Plan Survey. Under "Things you are interested in" she's written "Global Warming" "Declining Birthrate", and "Aging Population", and her "Hopes for the future" square is completely blank.
  • Imagine Spot: Frequently daydreams in class about far-fetched scenarios on an airship, explaining how Mio got her hair-ties, her twin tails, and her very person.
  • Intergenerational Friendship: She becomes fast friends with the Professor during her random visit to the Shinonome laboratory.
  • The Jinx: Inverted, if Episode 26 is any indication. She's apparently sort of a bad 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 involves 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: This happens to her often, since she frequently forgets to do her homework.
  • Straight Man: Occasionally, if Mio is acting up or playing sports, or if Mai is in "Boke" mode.
  • Terrible Artist: In contrast with Mio, much to the latter's dismay.
  • Wave-Motion Gun: When in enough pain, her screams let out these. One of them even pierces through all the planets of the solar system (and Pluto)!
  • You Have to Believe Me!: keeps stumbling into the most mind-blowing scenarios she knows no one will believe she saw, like the extremely old principal being spry enough to fight to the near-death with a deer who seems to have it out for him.

    Mio Naganohara
Don't ask how the hair decs stay there. No one knows the answer to that one.

Voiced by: Mai Aizawa (Japanese), Leah Clark (English)

"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.

  • Athletically Challenged: She's very physically fit, yet she can't clear a low jump bar, or do any gym activity that doesn't involve fighting.
  • Badass Adorable: 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. She even gets scouted as a boxer at one point.
  • 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 hell outta there and head for the hills!
  • Breath Weapon: When in enough pain, her screams let out these.
  • Covert Pervert: To the extent that she beats up Yukko, a police officer, an old man, and a goat all in the name of preventing people from finding out she draws Yaoi.
  • Cute Bruiser: See Badass Adorable. She's cute as a button, but pretty damn strong.
  • Flash Step:
  • Freak Out: Loses it over her Yaoi drawings being discovered and ripped apart.
  • 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-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 creates an entire romantic scenario between Nano & Sasahara when Yuuko convinces her they're 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. Even if it's something as inane as putting a shogi piece on her Mont Blanc.
  • Love Hurts: After seeing Misato "escorting" Sasahara, she goes into Heroic BSoD.
  • Moustache de Plume: She writes her Yaoi manga under the masculine pen name "Daisuke Naganohara".
  • My Life Flashed Before My Eyes: When she tastes her sister's kusaya (salted, sun-dried mackerel) jam the second time, the taste is so horrible that she sees her life flashing before her eyes.
  • Power Palms: During her fight against the green mooks.
  • Serious Business: Her food and her Yaoi.
  • Signature Hair Decs: She wears two wooden cubes in her hair which are her most identifiable feature. Aside from being kind of an odd choice for hair decorations, they're completely ordinary. Or are they?
  • Spectacular Spinning: Hits Yoshino with a corkscrew and attacks Yukko and Sasahara's goat with a Dragon Screw.
  • Straight Man: Most frequently of the main cast.

    Mai Minakami
Don't take what she says at face value.

Voiced by: Misuzu Togashi (Japanese), Brittany Lauda (English)

"I was joking."

Rounding off the protagonist 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 whittling Buddha statues.

Shinonome Laboratories

    Nano Shinonome
Sure, it's weird she's a robot, but look at everyone else.

Voiced by: Shizuka Furuya (Japanese), Monica Rial (English)

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.

  • Arm Cannon: Except it's equipped with tiny, harmless pellets instead of bullets. She also has one on her knee, for some reason.
  • Badass Adorable: She's incredibly sweet and cute, but chapter 178 has her show off surprising new features: rocket jet propulsion from her feet, a pellet-shooting cannon on her knee, a shield from her palm, scan vision and heightened hearing. Not to mention the Super Strength needed to hurl a giant boulder at her piggybank.
  • Become a Real Boy: She's a robot who wishes she could be a real girl, or at least to be able to pass as one. Unfortunately, the Professor's refusal to remove the wind-up key in Nano's back and her habit of installing weird new functions in Nano for her own amusement keeps getting in the way of that.
  • Berserk Button: Her many new inventions that the Professor secretly installs on her.
  • Born as an Adult: Downplayed since she's a teenager but she's stated to be only 1 year old.
  • Crash-Into Hello: Subverted. When she crashes into a boy from school, it results in an Earth-Shattering Kaboom instead, followed by both parties landing on separate rooftops
  • Do-Anything Robot: Except she can't play music.
  • Dreadful Musician: When she and the Professor are playing trumpets, Sakamoto comes in to scold the latter for the racket... except the Professor then shows she get any noise out of hers at all, meaning it was Nano making the dreadful sound, much to her embarrassment.
  • Everybody Knew Already: She thinks she has convinced people that she isn't a robot. She hasn't.
  • Face Fault: A built in feature, thanks to the Professor.
  • Fear of Thunder: She's scared of lightning, which makes sense, considering she's a robot.
  • I Just Want to Have Friends: Her main reason for wanting to be more human-like.
  • Ms. Fanservice: Not much of it, but at least compared to the other characters. One segment telling you about the animation studio and musicians has her in a swimsuit, and she's the only character to have visible breasts.
  • Nice Girl: Probably the nicest character in the show, alongside Sakurai-sensei.
  • Paper-Thin Disguise: She tries (with Yukko and Mai) to disguise herself from Mio by wearing a daifuku mask. Mio immediately recognizes her because she can still see her key.
  • Parental Substitute: The Professor's parents are never seen or mentioned, and Nano basically acts as a parental figure to her own creator.
  • Ridiculously Human Robot: Her screw is the only clue (or rather, dead giveaway) that she's a robot. Take it off, and nobody would guess. (Hell, even with it, Mio isn't initially convinced Nano is a robot right away).
  • Robot Girl: A robot with the appearance of a young girl. The only outward indication that she's a robot is the wind-up key in her back.
  • Rocket Punch: One of her functions is to launch her right hand like a rocket. Unfortunately for her, it tends to fly off whenever it wants.
  • Super-Powered Robot Meter Maids: In addition to her pellet guns, Chapter 178 reveals she also possesses Super Strength, Rocket Feet, Super Sight & Hearing and some kind of Energy Shield.
  • Swiss-Army Appendage: Both of her arms have various functions hidden in them, which the Professor tends to add without her knowledge.
  • Why Did It Have to Be Snakes?: She's afraid of cockroaches.
  • Willfully Weak: Chooses to not utilize even her less extreme functions, like speed-reading, for the sake of seeming that much more normal.
  • Wind-Up Key: She has a large one sticking out of her back, much to her dismay, as it's a dead giveaway to the fact that she's a robot. The fact that its only purpose is to launch her toe like a rocket doesn't help either (that and the Professor thinks it's cute). She also points out she can't sit in a chair normally or lie down on her back. She eventually realizes that this key is part of makes her who she is, and decides to keep it.
  • Wise Beyond Their Years: She's only 1 year old and has the body and mind of a teenage girl, but she's a lot wiser than her age would imply.
  • Younger Than They Look: She's 1 year old at the start of the series.

    Professor Shinonome
The creator of Nano. Hard to believe, right?

Voiced by: Hiromi Konno (Japanese), Jad Saxton (English)

Nano's 8-year-old creator. Aside from her ability to build incredibly advanced machines, she's a completely normal kid. Likes sharks.

  • Attention Deficit... Ooh, Shiny!: Being only 8 years old, she tends to be easily distracted. This often happens when Nano asks her about her gadgets, much to the robot girl's dismay.
  • Beer Gasm: She does this with milk in the anime's first opening.
  • Berserk Button: Do NOT insinuate that robots are not cute in her presence.
  • Big Eater: She can eat a month's supply of snacks and still have room for strawberry juice. An ongoing conflict between her and Nano is that she often wants to eat more snacks, even when Nano tells her she's not supposed to since it'll spoil her appetite for regular meals.
  • Bratty Half-Pint: She has her moments of being this, mainly by causing trouble for Nano in some way or making Sakamoto's life difficult.
  • Cheerful Child: She's generally a pretty happy, upbeat kid.
  • Does Not Like Shoes: Almost always shown barefoot. Justified in that she's almost always seen indoors, where she has no reason to wear shoes.
  • Everyone Calls Him "Barkeep": She's always referred to as Professor. We at least know her family name, but her given name is never mentioned.
  • Fear of Thunder: Not surprising at all, considering she's only 8.
  • For the Funnyz: Much of her antics fall under this.
  • Genius Sweet Tooth: Much like most other children, she loves sweets. Unlike other children, she's capable of creating robots so advanced that it counts more like creating life itself.
  • Hoist by Her Own Petard: Is often a victim of Nano's bean cannon.
  • Innocent Prodigy: A typical 8-year-old girl who just happens to be able to make a highly advanced artificial intelligence. Despite her scientific genius, she's still as childish as any girl her age would be and rarely ever thinks about the consequences of her actions.
  • The Kid with the Remote Control: Parodied like anything. Since she created Nano, she has full control over her abilities, most of which serve very little purpose aside from being funny. She'll even add new features to Nano's body without Nano's knowledge.
  • Labcoat of Science and Medicine: She's almost always seen wearing an oversized labcoat, indicating that she's a scientific genius despite her young age.
  • Never My Fault: Played for Laughs. She'll always blame Sakamoto for something that she screwed up.
  • The Pirates Who Don't Do Anything: Despite supposedly being a scientist of some kind, she's never actually seen doing any significant scientific work aside from making robots and gadgets solely to amuse herself. She seems to spend most of her day doing typical activities for an eight-year-old, like drawing or reading picture books (though the books she reads do tend to be science-related).
  • "Silly Me" Gesture: She'll often do this when questioned by Nano about the latest weird function Nano has been given.
  • Smart People Build Robots: Nothing quite proves how smart you are than building a Ridiculously Human Robot.
  • Spell My Name with an S: Even official translations vary on calling her "Hakase" or "Professor". The Vertical Comics manga uses "Professor", while the Funimation dub uses "Hakase". Prompting the confusion is the fact that "Hakase" is the Japanese word for "Professor", but the Japanase manga doesn't use the kanji for "Hakase" (博士), but instead spells it in hiragana (はかせ), which presents "Hakase" as a proper name rather than a title.
  • Third-Person Person: Justified because of her age, as speaking in the third person is considered child-like in Japanese.
  • Trademark Favorite Food: She loves omelet rice and strawberry juice.
  • Why Did It Have to Be Snakes?: She's terrified of dogs, especially Mai's two dogs.

"No matter how you look at it, that was too much petting."

Voiced by: Minoru Shiraishi (Japanese), Anthony Bowling (with collar), Macy Johnson (without collar) (English)

A black cat living with Nano and the Professor. He is able to talk due to a scarf the Professor created.


    Koujirou Sasahara

Voiced by: Yoshihisa Kawahara (Japanese), Seth Magill (English)

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.

  • Berserk Button: Don't tell him he can't bring his goat to school.
  • Blind Without 'Em: Misato makes the assumption that he is when she accidentally smashes his glasses' lenses, and walks him to class. Unfortunately for her, he isn't. They're just for show.
  • Catchphrase: "Well said!"
  • Classy Cravat: Which he only seems to wear to make himself look classy.
  • Cloud Cuckoolander: He's a little...out there in most of his appearances, and there's also his general habit of acting like a classy nobleman even though he's really from a family of farmers. According to Tachibana's sister in Chapter 109, in middle school he was only marginally better.
  • Contemplate Our Navels: The inspiration for his poetry often comes from rather absurd non-sequiturs involving anything nearby that happens to be occurring at that moment.
    (Nano's disembodied hand rockets past.)
    Oh! 'Perhaps it is my right hand, trailing clouds across the blue sky. Sasahara." Not bad!
  • Extreme Omni-Goat: His goat, Kojirou.
  • Full-Name Basis: How he addresses Misato Tachibana.
  • Hidden Depths: He's actually proficient in kendo, and he used to train with Tachibana in middle school.
  • Hot-Blooded: During his introductory scene. His goat is really important to him.
  • The Load: Seems to be this in his duties for the festival committee. Which is, naturally, a source of frustration for Misato.
  • Made of Iron: Kojiro can take anything Misato throws at him, and not even flinch.
  • Mock Millionaire: He's actually not that rich, he simply acts like it.
  • Oblivious to Love: He doesn't ever seem to have a reaction to Misato's aggressive behavior other than polite thanks for when she does stuff for him.
  • Purely Aesthetic Glasses: "Just for show" as he says.
  • Shirtless Scene: Derisashu~. It happens during the Josei segment in which Mio believes Nano and Sasahara are dating.
  • Upper-Class Twit: Subverted. He's actually from a family of farmers and only acts like he's upper class, though he's still very much a twit.
  • We Named the Monkey "Jack": Named his goat after himself.

    Misato Tachibana
The lengths she'll go to in order to deny her love for Kouji—*boom*

Voiced by: Chika Horikawa (Japanese), Madeleine Morris (English)

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.

Voiced by: Kazutomi Yamamoto (Japanese), Kyle Igneczi (English)

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.

  • Black Bead Eyes: One of the few characters to have those eyes consistently.
  • Butt-Monkey: He tends to be on the wrong end of many of Nakamura's Nano-traps.
  • Delinquent Hair: Subverted; despite having a mohawk, he's not a delinquent at all and is very down-to-earth (though Weboshi thinks he is a delinquent and likes him because of it). In fact, he didn't even style his hair that way; it grew like that naturally. Later on, he loses his hair, but it grows back into its natural shape.
  • Expository Hairstyle Change: He has the mohawk for most of the early series, but loses it when he rips his hair out trying to remove a mask glued to his head. He only gets his hair back in the final volumes.
  • Face of a Thug: His mohawk makes him look like a delinquent and a bad guy (In fact, it's the main reason Weboshi likes him), but he's actually a very Nice Guy.
  • Heir to the Dojo: Well, more or less his father's daifuku business, and he wants no part of it.
  • Magic Versus Science: His lifegoal is to prove that the supernatural doesn't exist.
  • Misery Trigger: He isn't at all happy about the fact that his hair naturally grows in a mohawk style, and actually gets pretty sad when it is pointed out. His dad has the same problem, but he eventually learned how to comb it down.

    Haruna Annaka
This is pretty much Annaka's default expression.
Voiced by: Kaori Sadohara (Japanese), Kristen McGuire (English)


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" (a Japanese onomatopoeia for a rabbit jumping).
  • Big "WHAT?!": See Catchphrase.
  • Butt-Monkey: To the point to compete with Yukko since the universe seems to enjoy messing with her, putting her in situations where she meets weird people, ends up being scammed, is abducted by aliens, and even dies after being hit by a really fast-flying beetle.
  • Catchphrase:
    • Eeeehhhh?!
    • Her entire character song consists of only two words: "Pyon" and various forms of "Eeeehhhh?!"
    • "(Annaka describing some activity that she's going to do and how she never did it before) I'm really looking forward to it!".
  • Only Sane Man: The humor in her sketches comes from her reactions to the insanity that unfolds around her.
  • Power Limiter: Her ribbon is apparently weighted.

    Kenzaburou Daiku 
Voiced by: Ryouta Yoshizaki (Japanese), Stephen Fu (English)

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.
  • Cool Plane: Takes a helicopter to school.
  • Didn't Think This Through: Daiku didn't know there was actually a sport called "Go-Soccer" when he invented the club.
  • Oblivious to Love: Downplayed. When he asks Sekiguchi why she bothers with the club when she's clearly not interested, it takes him a bit to realise why she blushes, but he does get it eventually.
  • Only Sane Man: In comparison to most of the cast, especially in comparison to 3/5ths of the Go-Soccer Club. This is eventually subverted, as his casual attitude in regards to his ridiculously wealthy background make him just as strange.
  • Rich in Dollars, Poor in Sense: He's a good kid, but he doesn't tend to think things through. He calls in a specialist for what turned out to be a light cut on the head, and he was encouraged to fit himself into a bird stall by Makoto.
  • Token Rich Student: Unlike Sasahara, who acts like a classy nobleman even though he's from a family of farmers, Daiku really is from a rich family despite going to the same middle-class high school as everyone else. He doesn't really flaunt his wealth much aside from taking a helicopter to school, however.

    Yuria Sekiguchi 
Voiced by: Ai Hirosaka (Japanese), Apphia Yu (English)

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.

  • Beginner's Luck: While she was just introduced to Go-Soccer and doesn't understand a lick of it, she's apparently so good at it that she not only outdoes more experienced players, but also wins nationals by the end of the manga.
  • 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 (Japanese), Dallas Reid (English)

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

  • Adorably Precocious Child: While he was perfectly willing to hold hands with Izumi when he was a child, his classmates mocking him for it caused Makoto to begin doing household chores and going to school alone in an effort to look mature. He only unconsciously returns to holding Izumi's hand when he gets impressed by her English-speaking ability.
  • Covert Pervert: When Izumi finds a porn magazine under his futon, he furiously denies that it's his, but he still gets upset when she decides to throw it away.
  • Eyes Always Shut: Even when shocked, his eyes remain shut.
  • Foolish Sibling, Responsible Sibling: Because Izumi is often clumsy, Makoto has to pick up her slack at home. However, their family in general flips between being foolish and responsible on a daily basis. Chapter 154 reveals that his behavior was born out of a need to look more mature.
  • Wrestler in All of Us: Performs a German Suplex on himself, if that makes sense.


Voiced by: Kouta Yamaguchi (Japanese), Tyson Rinehart (English)

A student with an afro. Best friends with Nakanojou.

  • Book Dumb: If chapter 196 is to be believed, he's proud of not studying, and of the bond he has to certain students over it.
  • Determinator: Quality be damned, Tanaka will get Nakanojou to see a parachuting firework, even if he burns up his back to do so.
  • Hammerspace Hair: In one gag he is seen pulling out numerous things from his Afro including Sakurai-sensei's favourite treat.
  • The Reveal: Chapter 137 reveals that Tanaka's huge hair is just a wig, and he has straight hair underneath it. He wears his hair normally in the final volumes.


Voiced by: Youko Tamaoki (Japanese), Kathryn Taylor Rose (English)

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

Voiced by: Yumi Higuchi (Japanese), Kara Edwards (English)

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 (Japanese), Emily Neves (English)

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.
  • Digging Yourself Deeper: After Misato found out about the fake love letter, Mihoshi decided to double down and pretend she intentionally gave Sasahara her own love letter in order to make Misato more honest about her feelings. All it did was make her even more delusional.
  • Girlish Pigtails: Sports long, very thin ones.
  • Love Confessor: Attempted. She planned on getting Misato's feelings out in the open by sending Sasahara a Love Letter in his shoe locker. The problem is that she sent it with her name, which Misato found, and led to a short misunderstanding.
  • The Resenter: Towards 'that damned genius' Yoshino Naganohara regarding her kendo skill.

Voiced by: Ryota Takeuchi (Japanese), Howard Wang (English)

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

  • Chekhov's Gunman: Makes an early appearance in a Go-Soccer skit in order to officially quit the club. Then, once Go-Soccer turns out to be real, his own comedic traits come back into the forefront.
  • Large Ham: If his acting referee for the match in Episode 19 is anything to go by. Go-Soccer is Serious Business.


    Izumi Sakurai
Voiced by: Mami Kosuge (Japanese), Tabitha Ray (English)

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.

    Manabu Takasaki
Voiced by: Tetsu Inada (Japanese), Shawn Gann (English)

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 (whether Izumi has a boyfriend, not whether Makoto does). Both instances end predictably.
  • Gratuitous English: Prone to bursting into it when he messes up.
  • Hot-Blooded: And not just when Izumi is the subject matter. He tends to go all-out whenever he's fired up in general.
  • I'm a Man; I Can't Help It: Why he allows himself to be bribednote  into being the Go-Soccer Club's advisor.
  • Imagine Spot: Often, and always involving Izumi.
  • Large Ham: Especially when Izumi is the subject matter.
  • Mr. Imagination: Keeps getting caught up in Imagine Spots involving one Izumi Sakurai.
  • Not So Above It All: Comes off as a normal teacher at first.

    Kana Nakamura
Voiced by: Kaoru Mizuhara (Japanese), Lydia Mackay (English)

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.

  • Accent Upon The Wrong Syllable: Tends to happen when she gets excited.
  • And Call Him "George": Has no idea how to care for cats.
  • Butt-Monkey: Again, not quite on Yuuko or Sakamoto's level, but she still qualifies.
  • Chekhov's Gunman: In Episode 3, she was looking for her cat Taisho. note 
  • Epic Fail: She is the Epic Fail personified. Few people ever fall for their own Poisoned Chalice Switcheroo twice.
  • For Science!: The dub peppers this into most of her internal monologues about capturing Nano.
  • Gratuitous English: During her visit to the Shinonome household.
  • Heel–Face Turn: Going by chapter 172 of the manga, by the time the Professor is in high school, Nakamura stops trying to kidnap Nano and instead takes up residence in the Shinonome household itself to learn from the Professor directly.
  • Hoist By Her Own Petard: Her attempts at the Poisoned Chalice Switcheroo both failed because she drank the coffee she herself drugged.
  • Ineffectual Sympathetic Villain: Although she tries to kidnap Nano to learn more about her, she fails so often and so hard at it that it's hard to see her as much of a villain, let alone a threat. According to the Time Skip chapter of the manga, she quits this trope altogether as she performs a Heel–Face Turn anyway.
  • Innocent Innuendo: "I've come to learn more about you, Shinonome"!
  • Kindhearted Cat Lover: Played with. She likes Taisho, but has absolutely no idea how to treat him.
  • Labcoat of Science and Medicine: She typically wears one at school, due to being a science teacher with Mad Scientist leanings. When Takasaki runs into her outside of school, he remarks how it's unusual to see her without it.
  • Mad Scientist: It's not really known whether she is in other aspects (though she is implied to have tried to drug students before), but she is so obsessed with kidnapping Nano to figure out how she works that she easily qualifies.
  • Not Again: People's reactions when they learn she's passed out. Implying she's either incredibly careless, or has tried to drug students before.
  • Pit Trap: Another of her schemes to catch Nano. Predictably it fails.
  • Poisoned Chalice Switcheroo: She inflicts this on herself in Episode 15. Twice and no one was there the second time.
  • Pretty Freeloaders: The timeskip chapters reveal that she eventually starts living in the Shinonome household, still intent on learning more about Nano.
  • Serious Business: Everything, especially if it involves Nano.
  • Stalker Without a Crush: To Nano, who she's fascinated by due to her being a robot. Though Nano briefly thought Nakamura had a crush on her when the teacher said she came to the Shinonome household to learn more about her.
  • Tsundere: Maybe since she gets flustered every time someone calls her cute.
    • In the later manga chapters, she's specifically tsundere for Takasaki, thanks to multiple random events leading her to think he has a crush on her.

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

  • Bald Head of Toughness: He's actually completely bald in spite of the Toupee making it look like he's merely balding, and of course, he's one tough customer, as his idea of catching a deer that wandered on school grounds is to literally fight it face-to-face with a bulletproof vest for protection, and winds up pulling off an epic German Suplex on it.
  • Cannot Tell a Joke: Though unlike Yuuko's which are plain terrible, his jokes are simply way outdated.
  • Crazy-Prepared: Wears 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 (Japanese), Charlie Campbell (English)

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 (Japanese), Maxey Whitehead (English)

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.

  • Affectionate Nickname: Tamamura calls her "Naganon", the same nickname Mio's middle school friend Bera gave her.
  • 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.
  • Cordon Bleugh Chef: Deliberately so. Her jam is so bad, she almost literally qualifies as a Lethal Chef.
  • Cute Bruiser: Being surprisingly strong whilst looking adorable seems to run in the family.
  • 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.
  • Strong Family Resemblance: A quick scene of Mio as a baby shows that Yoshino looks a lot like her mother.



Voiced by: Misato (Japanese), Megan Shipman (English)

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 (Japanese), Doug Jackson (English)

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.

  • Abusive Parents: Mr. Nakanojou's a hardass on Tsuyoshi for anything short of accepting the daifuku business. When Tsuyoshi protests enough, he starts tricking him into doing seemingly benign tasks that are actually malicious to him (see: coating the inside of a daifuku mask with paint to make Tsuyoshi stuck until he agrees to inherit the business).

Mitsuo ("Micchan")

Voiced by: Kaoru Mizuhara (Japanese), Sarah Wiedenheft (English)

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 (Japanese), Sonny Strait (English)

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

  • The Charmer: Instantly wins over Nano and Professor.
  • Clever Crows: After he puts on Sakamoto's scarf, he turns out to be highly intelligent and well-spoken.
  • Non-Standard Character Design: Most birds are either realistically drawn or look a bit like marshmallow peeps. This one is cone-shaped.

Biscuit #2

Voiced by: Etsuko Kozakura (Japanese), Alison Viktorin (English)

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: Zach Bolton (English)

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, and is prone to sleeping in the weirdest positions, times and places.
  • Sleepyhead: Due to being overworked.


A morose girl who has an uncanny resemblance to Yuuko except for her visibly depressed-looking face. Yuuko is mistaken for her before Mio encounters her in person.

  • Face-Revealing Turn: Does this with Mio and Annaka, who initially think that she is Yuuko.
  • Famed in Story: Enough so that Yuuko is mistaken for her by two other girls. Though Yuuko and Mio don't know about her at first.
  • Nightmare Face: Annaka, the Professor, and the Crow seem to think so, as they react with fear upon seeing it.
  • Non-Standard Character Design: Her face is unusually detailed compared to everyone else. While other characters may temporarily get more detailed during an Art Shift to convey their changing emotions, this is how Doublecheeseburgirl normally looks.
  • Oddball Doppelgänger: She looks exactly like Yuuko Aioi, right down to her clothes, except that she has a depressed-looking and unusually detailed face. She also speaks with a heavy "hick" accent and frequently does a strange and apparently famous squatting dance to cheer up kids.

    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 (Japanese), Greg Dulcie (English)

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 (Japanese), Emi Lo (English)

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.
  • You Have GOT to Be Kidding Me!: Even she was in shock and disbelief over the fact that Dolph died merely by stumbling over his feet.


Voiced by: Takaya Hashi (Japanese), David Novinski (English)

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.

The Mooks
Voiced by: Hōchū Ōtsuka (#8), Jun Fukuyama (#66), Joji Nakata (#22), Akio Ōtsuka (The Negotiatior) (Japanese), Sterling Gafford (#8) (English)

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.

  • Blown Across The Corridor: In Episode 21, Number 8 gets blasted so hard that he ricochets against the walls until he goes full turn and hits Mio in the back.
  • Death as Comedy: Their individual deaths tend to be Played for Laughs more often than not.
  • Decapitated Army: The moment that Dolph gets himself killed, they immediately surrender and the rebellion against the Fey Kingdom is over.
  • Elite Mook: Number 8 is always the one that inadvertently snaps Yuuko into reality.
    • Also, every mook who doesn't have a number on their cap. In theory.
  • Epic Fail: Word of advice: if you find yourself in possession of the two artifacts that might make you king of the land, don't put them on the sill of a window of a moving airship.
  • Face Framed in Shadow: Even if the viewer can see beneath their green caps, their eyes are never visible.
  • Mass "Oh, Crap!": After Dolph accidentally killed himself.
  • No Name Given: Some of them are given nicknames, the rest are given numbers as names, but neither of them have actual names.
  • 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.

The Clueless Shinigami
