    Main Characters 

Risa Koizumi
Voiced by: Akemi Okamura

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.

Risa is also very fond of video games, always seen in her spare time playing some, especially Virtual Date kinds.

Also she seems to like rabbits a lot, having a lot of bunny shaped things.

  • 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.
    • Things like: A red purse, a necklace, a ring, her cellphone, something for the bath, among other things.
  • Caught the Heart on His Sleeve: To Otani, to physically stop him from walking over to talk to his ex-girlfriend.

    • At the beginning, she's sleeping… while standing… in the training in row of her school!
    Risa [Suddenly awakens]: DAMN IT! My summon monsters have been annihilated!
  • Dogged Nice Girl: She becomes this when she realizes her crush on the lead male 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.

  • Huge School Girl: Basically, half the premise is based on she being a girl more taller than 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.

  • Kansai Regional Accent: Everyone speaks this way because the story takes place in Osaka.

    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!
