Minatsu is a bold character and Student Council Vice-president. A tomboy with impressive athletic skills, and is surprisingly also good in math, which Ken considers to be uncharacteristic of her. She's popular among girls and has a bit of a yuri taste. She's in the same class with Ken but she's an orthodox tsundere without any 'dere' (short for dere-dere) to be found. She also has a little sister, Mafuyu. She's very protective of Mafuyu and despises anyone who tries to hurt her. She's is into a lot of Shōnen manga as most of her suggestions tend to be based on typical Shōnen manga plots.
