http://static.tvtropes.org/pmwiki/pub/images/risa_koizumi___colour___by_milky_mou_5057.jpg
Voiced by: Risa Hayamizu (Drama CD), Akemi Okamura (anime)

Risa is 172 cm tall and thin and has light red hair and brown eyes.

Risa is seen as impulsive and strong-willed, rarely willing to display her softer side. She is a tsundere. She is also very clumsy and apparently talks a lot, usually in not such a good way.

It is strongly stated by the other characters that she is very funny for a girl and a fun person to hang out with. At the same time, she also implies she is not cute and girly, the type of girls that are very appreciated in Japan, possibly due to her tall stature. Her favorite artist is Umibozu, her admiration for him going to the point of obsession.


  • A-Cup Angst: After meeting Hitomi, a rather buxom woman who flirts with Atsushi, Risa comments that she has no breasts with a rather dejected look on her face.
  • Bunnies for Cuteness: She has an affliction for things shaped like bunnies, such as: a red purse, a necklace, a ring, her cellphone, bath items, among other things.
  • Caught the Heart on His Sleeve: To Otani, to physically stop him from walking over to talk to his ex-girlfriend.
  • Class Clown: With Otani. They are seen as their class' comedy pair known as the "Hanshin-Kyojin" and usually play the Boke and Tsukkomi Routine around their peers (classmates and teachers included).
  • Class Representative: With Otani. Averted, because they are actually the "Class Clowns".
  • Cry Cute: She looks pretty when she is crying, usually after being rejected (many times) by Otani.
  • Cute Clumsy Girl: She is very clumsy (and she is often falling around, like that time at the Umibouzu's concert), even in moments when she doesn't have to be acting like that (such as the time she was standing in row with the rest of her class... when she was falling asleep and snoring loudly).
  • Dogged Nice Girl: She becomes this when she realizes her crush on Otani. It doesn't help that all of her friends, usually Nobuko and Nakao, are constantly encouraging her on in her pursuit of him.
  • Dude Magnet: Even if she's not that admired for her beauty and is often regarded as no girlfriend material due to her being not "conventionally cute" because of her height and tomboyishness, she has Otani, Haruka and Kohori being attracted to her. Also, in the chapter where She Cleans Up Nicely, two guys talk about how they find her cute and one of them implies he wants to make a move on her after the photoshoot before Otani scares them off.
  • Effortless Amazonian Lift: Koizumi carries Otani in her arms after he failed to escape her.
  • Establishing Character Moment: Her first scene has her sleeping while standing and snoring. Then, when she suddenly wakes up, she yells "DAMN IT! My summon monsters have been annihilated!" and everybody laughs.
  • Everyone Can See It: Everyone in their friends' cirle and at school, know that she and Otani are perfect for each other.
  • Fiery Redhead: She has a really hot temper, making her really impulsive in some of her decisions.
  • Finishing Each Other's Sentences: With Otani. They are so good at this that they become a comedy sensation at their school, although it's very unintentional, and usually Played for Laughs.
  • Huge School Girl: Basically, half the premise is based on she being a girl more taller than the Japanese average.
  • Insecure Love Interest: To Otani. She thinks very highly of Otani's ex-girlfriend, Kanzaki, wondering why would he pick her over his ex-girlfriend. This is partly because of his hard and cold behavior around her and his inability to tell her how he feels.
  • Insult of Endearment: She calls Otani as "midget" and "shrimp", even after their Relationship Upgrade... although she does so in a considerably softer manner than before.
  • Ironic Name: Her last name is Koizumi and means "little spring" in Japanese, and she is taller than any other girl in her school. This is lampshaded in the first scene.
    "I've been tall ever since I was young. When we line up for morning assembly, I'm always at the end. But I happen to be named "Koizumi". Sorry, it's not "Oizumi" (big spring)."
  • Like an Old Married Couple: Her relationship with Otani is seen as such by the rest of their classmates, that they even lampshade it.
    Girl: Ahahaha, They're at it again~
    Guy : It'd be better if you two did a "married couple" comedy duo for the school festival.
    Otani: ARE YOU STUPID! DON'T SAY SUCH STUPID THINGS!
    Koizumi: How embarrassing~ What "married couple" it's still too early!
    Otani: *smack* DON'T GET INVOLVED TOO!
    Koizumi: ACK!
    Nakano-Sensei: ''Aah...'' We don't have any time left, so we'll just let the married couple class representatives be the committee.
  • The Matchmaker: When she was trying to hook up Otani with Chiharu. She ended up developing a Matchmaker Crush on Otani.
  • One Head Taller: She is taller than Otani by a head.
  • "The Reason You Suck" Speech: Risa likes to hand these out after punching people to get them to calm down and think more rationally. She has done this to Otani and Mimi.
    Risa: [Risa punched Otani.] AHOU! It doesn't matter if you're tall or short! You're a man as long as you have a *beep*!!.
    Otani: Girls shouldn't use such indecent words!
    Risa: Just shut up, WILL YOU!? PEOPLE HAVE BEEN CALLING YOU SHORT FOR ETERNITY ALREADY! WHAT’S SO EMBARRASING ABOUT BEING CALLED SHORT BY A SINGLE GIRL!? If you're going to be bothered by such trivial matters... Beat ... Then you don't even have the right to like anyone! LOSER!

Atsushi Otani

http://static.tvtropes.org/pmwiki/pub/images/165808-image_gallery_8759.gif
Voiced by: Takahiro Sakurai (Drama CD), Akira Nagata

Otani is a really short guy, standing only 157 cm by 12th grade. He has a small stature but he is a bit muscular due to his constant basketball training. He has orangey brown hair and brown eyes.

Otani can be tough and rude on the outside, trying to look more manly. At heart, however is kind, silly, naive, oblivious, funny and a good friend. Like Risa, he likes Umibozu, water parks, games and the two tend to do things others wouldn't (like riding a rickshaw). Also, he displays a happy and care-free attitude,much like his girlfriend.

He is quite popular with girls even though he is completely oblivious to Risa's, Seiko's and Mimi's feelings towards him.

By the end of the series he follows his dream to become an elementary school teacher,stating he has always liked kids to the point in having some 10-years old as his basketball friends.


  • Green-Eyed Epiphany: Otani has never been able to see Risa as anything other than a friend...until she's suddenly swooning over Maity-sensei.
    Otani: You're always saying "Maity this, Maity that"!! That's why I'm so annoyed!!
    Risa: ...Why should you be annoyed?
    Otani: How should I know? Annoying things will, of course, annoy me!! Don't ever mention his name again!!
    • Purposefully invoked by Maity-sensei via his "magic" in order to make Risa happy.
  • Green-Eyed Monster: He easily gets jealous (such as when Maity offered Risa to take her home) even though, deep down, he knows he doesn't have to worry since Risa is always going to be in love with him.
    • He became insanely jealous when he saw Risa with Kohori. He even told Risa that he'd punch Kohori in the face if Risa was with him again.
    • Oh, and let's not forget the chapter from the manga's volume 12 where Risa had to model with Mimi (and as a result, ended up getting absolutely dolled up) and some guys comment on how they find her cute and one of them implies that he wants to make a move on her. He's not amused by their comments and even makes an "angry beast" face at them to scare them off!
  • Hair-Trigger Temper: Has a fuse as short as his height.
  • Has a Type: Otani likes short, cute, and helpless girls, and he seems to think that they need to be feminine and a bit shy. Ironically, he ends up falling in love with a temperamental Huge School Girl, who isn't seen as very feminine by her peers.
  • Heroes Want Redheads: Although Otani didn't fall for her at first, Koizumi is definitely a Fiery Redhead, just like him.
  • Insult of Endearment: With Koizumi. He calls her “amazon” and “totem pole”, though after the Relationship Upgrade , he still occasionally call her this, though in a considerably softer manner than before.
  • It's All About Me: Otani is often arrogant and holds a high opinion of himself.
  • Jerk with a Heart of Gold: He acts as a jerk, but he definitely cares for his friends, especially Koizumi... even though most of the times, he has a lot of moments where he is more of a jerk with her, due to his tsundere nature.
  • Keet: His usual state. Small? Check. Cute? check. Colorful? check. Energetic? check, check and check.
  • Like an Old Married Couple: With Koizumi.
    Girl: Ahahaha, They're at it again~
    Guy : It'd be better if you two did a "married couple" comedy duo for the school festival.
    Otani: ARE YOU STUPID! DON'T SAY SUCH STUPID THINGS!
    Risa: How embarrassing~ What 'married couple' it's still to early!
    Otani: *smack* DON'T YOU GET INVOLVED TOO!
    Risa: ACK!
    Nakano-Sensei: ''Aah...'' We don't have any time left so we'll just let the married couple class representatives be the committee.
  • Tiny Guy, Huge Girl: Tiny Guy to Koizumi's Huge Girl. Tiny Guy to Koizumi's Huge Girl. He is a guy with a height below most average guys and she is a girl who’s taller than average. Do the math!
  • Tsundere: A rare male example of Type A with heavy emphasis on the "tsun" part. Otani is often showing the "tough" kind of love, rarely expressing directly his feelings for Koizumi. His pet name for her could be considered "idiot" or "stupid" since he always calls her that way, even when blushing.
  • Unrequited Love Switcheroo: With Koizumi. Played with. Risa falls in love with Otani, but Otani rejected her because he can’t see her like “more than a friend” (maybe because she’s taller than him too). Finally Risa gives up with Otani and she have a fangirl crush on Maity-sensei… Otani gets unwittingly jealous of Maity and finally realizes about his feelings for Risa in a Green-Eyed Epiphany (invoked for Maity-sama.)
  • Vitriolic Best Buds: With Koizumi. After they make a "truce" about hook up each other with their love interests (and fail) and after their deal about who gets a boyfriend/girlfriend first, they spend more time together and becomes close friends (they still fight, of course.)
    • Nakao mock Otani quite often too,and Otani yells at him when he does or when he say something (he considers) stupid.
    • With Yoshi in the manga. Otani gets angry about him because he's a jerk,but he is his friend anyways.
    Otani punches Yoshi.
    Yoshi: That hurt!
    Otani: No matter what you say, you are annoying! You are just trying to act cool!
    Yoshi [punches Otani]: I'm not really freaking trying to act cool!
    Otani: If that's how it is, it's really not cool at all!
    Yoshi : Shut up,tiny! I can't be friends with someone so tiny!
    Yoshi : It's like you're the one who is tiny! What should I do since we don't have a relationship?
    Otani: We do have a friendship! YOU ARE MY FRIEND!
  • Will They or Won't They?: Will the guy with a height below most average guys (Otani) and the girl who's taller than average (Risa) finally get together? Answer — Yes, They Do.
