Yutaka Kashio

Yutaka Kashio is a B-rank attacker and a member of Ouji Unit.

Kashio is stiff and very formal when speaking to his superiors, a consequence of being raised to address his own parents in the most polite manner. He can work himself up quickly when his expectations are not met, although he will calm down just as easily when given an explanation. He has a keen sense of responsibility and is very serious about his studies.
