磯野 一郎太

A classmate of Kenichi's, Sepia is the one person able to outdo his eccentricity. He claims to be able to talk to fairies and often speaks about bizarre subjects, inevitably incurring Touka's wrath. A fanatical devotee of Higuchi Saburou, leader of the civil uprising in the past, he resents Kenichi for being a 'dog of the nation'. He is romantically infatuated with Touka's mother, Kyouko.
