Itokazu, Maki

糸嘉州マキ

Kio's teacher, club manager, and leader of the Japan branch of the "Beautiful Contact" secret society. Because Eris lacks what Itokazu considers stereotypical alien traits (tentacles, green skin, etc.), she firmly believes that Eris, despite the obvious, should not be allowed to be mankind's first "official" alien contact. Though her group attempts to force Eris to leave Earth, a third party beats them to Eris, forcing her to help Kio rescue her under threat of having their identities revealed.
She spends a lot of her time chaperoning Kio and his sci-fi movie club, all the while complaining about the Catian's near human appearance.
