Uesugi Keijirou

Jinyou living in Kamizawa, and vice-chairman of its academy's student council. His height is really short, which resulted in him having Napoleon complex (alias "short man syndrome"), but basically he's a lad brimming with vitality. Childhood friends with the Ichinotani siblings and the student council accountant, Nanami Io.
His youkai ancestor is a giant species called Daidarabotchi (a giant youkai touted to have created many geographical features in Japan), which grants him powers whereas he can't feel the weight of anything he grasps. His parents are managing a small, cheap, but delicious soba shop, where he often has to help out by doing deliveries and such.
