A-ko Magami

A-ko, a red-haired girl who seems to be near invulnerable with superhuman speed and strength, is the heroine of the series and lives in Graviton City, Japan. A-ko is usually very friendly, cheerful, and polite and always tries to lead a normal life despite abilities. However, she does have a fiery temper and is very dangerous when angered. She has a large appetite and a tendency to oversleep on school days. Her constant friend is C-ko Kotobuki, whom she has known since kindergarten. Although A-ko can sometimes be frustrated with her, she truly loves C-ko. Both are transfer students to Graviton High, but wear their former school's sailor-style uniform for most of the film.
