Yutaka Kashio  

, 樫尾 由多嘉

Yutaka Kashio is a B-rank attacker who belongs to the Ouji Unit. Although he comes across as reserved and formal when communicating with superiors, this is due to having been raised to treat his own parents with utmost respect. He may become agitated if his expectations are not met, but once provided with an explanation, he quickly composes himself. Kashio takes his responsibilities seriously and places great importance on his studies.
