Naganohara, Mio

長野原みお

A bright and cheerful girl with azure-blue hair styled in pigtails secured by two small wooden cubes. She appears more "normal" compared to her friends Yuuko and Mai, although she possesses a very short temper and is prone to tantrums. She has a crush on Koujirou.
Mio is intelligent and excels academically, leading Yuuko to frequently copy her homework. She enjoys drawing yaoi in her notebooks but is mortified by the prospect of it being discovered, often displaying inhuman strength when attempting to conceal it.
