Karakter & Staf

Satsuki Gokajou

Utama

Female

The athletics coach, Satsuki prefers brawn over brains and has a loud personality. She is seen as very aggressive and violent, acting or speaking without thinking things through, but with a very sweet personality underneath. She is often referred to as "The Bear-Woman" for she is prone to wear pajamas with bears on them and acts like an animal.

Kaoru Sasajima

Kisaragi Ninomai

Utama

Female

The introverted science teacher who acts like a cultist. She has a personality similar to that of Chikage from Sister Princess except that she is far more interested in science and things that can be explained through science. Though she usually comes across as 'emotionless', Kisaragi is an incredibly warm, loving, sweet and kind-hearted person who is fond of cute things (such as baby animals, pink pajamas and her son), and cares deeply for the people around her. She is actually an alien, which explains her high technological skills.

Akiko Kimura
