Kou minamoto

Kou is a tall teenage boy with short, spiky dirty blond hair, light blue eyes, and two protruding canine teeth. His delinquent-like personality and aura make him relatively unpopular.

He wears a black shirt underneath his teal Kamome Gakuen Middle School uniform with brown stripes, which is sometimes left unbuttoned. He also sports a cream-and-brown striped tie that occasionally hangs untied around his neck and a red sweatband on his right wrist. Kou is always seen wearing a red traffic-safety amulet (omamori) as a piercing on his right ear.

Kou keeps his raiteijou―a spirit staff―around with him at all times as a weapon and disguises it as a black umbrella when he is not using it Kou is cheerful, direct and tends to jump into things headfirst without properly thinking them through. However, he has been shown to grow more mature as the series progresses.

He is often misjudged as a bit of a delinquent or rude, but this is actually not the case. He is rash and loud but is also simultaneously very kind and caring. He makes a distinct effort to be polite, as seen when even though he was about to face off with Hanako upon their first meeting, he still took the time to be polite to Nene and warn her about the perceived danger.

Kou has a strong sense of justice, and was also kind and open-minded enough to revise his opinion on Hanako and became friends with him, despite the pressure from his older brother to exorcise the ghost and the brothers' long-held belief that all supernaturals are bad.

He is very loyal to his friends and helps them in any way he can, no matter the danger. He is also easily flustered and sometimes makes mistakes due to rushing into things too quickly.
