Isurugi, Mio

石動美緒

Isurugi is Taro Sado's senior. She heads his school club and treats Taro violently because of her superiority complex. She claims to be a deity. She also suffers from ailurophobia. She is an extreme tsundere who repeatedly attacks Taro in an (unsuccessful) attempt to cure his masochism.

Spoiler

Mio does not get along well with Tatsukichi when his alter-ego surfaces while cross-dressing, especially because Tatsukichi belittles Mio's bust size whenever his alter-ego comes out. She does not quite realize that she has an innate sadistic personality, which may explain why she constantly resorts to violent measures to cure his masochism. She is shown to be very athletic, but Arashiko has said she is not very good at studies.
