Minamoto Kou is a student at Kamome Academy's Middle School Division and a member of family of exorcists, the Minamoto Clan. Also the younger brother of the clan. He is often misjudged as a bit of a delinquent or rude, but this is actually not the case. He is rash, loud but is also simultaneously very kind and caring. Kou is cheerful, direct and tends to jump into things headfirst without properly thinking them through. Kou has spiky blonde hair, a light blue jacket and a traffic safety earring.
