Characters
Main characters

Tooru Ichii (一井 透 (トオル) Ichii Tōru)
Voiced by: Aoi Yūki
A short first year student who often has overly long sleeves. Due to her short and skinny stature, she often has trouble finding clothes that fit her. She has been friends with Run since kindergarten, often getting lonely when separated from her and threatening anyone who tries to make a move on her.
She disliked Yūko at first, since her first impression of her was seeing her in a compromising situation with Run, and since then constantly teases her at every opportunity. She has a pet cat named Tansan (炭酸, named after fizzy drinks).

Run Momoki (百木 るん Momoki Run)
Voiced by: Kaori Fukuhara
A blonde second year student with a parakeet like hairstyle and Tooru's best friend. She is incredibly ditsy to the point that her friends often have to stop her from hurting herself in the process.

Yūko Nishi (西 由宇子 (ユー子) Nishi Yūko)
Voiced by: Minako Kotobuki
A long haired second year student and Run's classmate. She is something of a scaredy-cat who often finds herself at the mercy of Tooru's teasing, usually because she is envious of her tall and well endowed figure.

Voiced by: Yumi Uchiyama
She is a second year student and Run's classmate who sports pig-tails and glasses. She is often called by Run, Yuko, and Tooru by her nickname, Nagi. She is pretty intelligent and often makes quip remarks to her friends.
