Aino Karito

Jinyou living in Kamizawa and a member of its academy's student council. His long silvery hair and dreamy expression makes him very popular among girls.
His jinyou origin is from a youkai ancestor known as Nuppeppo (a youkai known as an animated lump of decaying human flesh). Due to this ancestry he's extremely fragile to the point where he dies easily and often, but his body revives soon after regardless of the damage it received.
He's in the same year with Kisaragi Soushichi and their relationship could be described as best friends.
