Ordered by Kuyou to keep an eye on the Newspaper Club (to make sure it wasn't doing anything the Student Police considered "illegal"), Keito is a spider-woman. Her animated incarnation places her in charge of a rival "super newspaper club" which would have replaced the current one. Keito also has 3 underlings, whose names are Tonko Oniyama, Shijimi Chouno, and Sumae Mizuno, who were made servants by her venom, all of whom were members of past clubs who the Student Police shut down; she also wanted to add Kurumu to her clique.
