Hiryuu Ruka

A detective from the Seventh Republic who had a hard time taking his work seriously for the past ten years, ever since he lost his mentor in the Cult Massacre. Because of this, he works in Section 13, also known as "Sideliners", where all the problematic detectives gather.
On the surface he is a laidback detective, but behind the scenes he obsesses himself with a certain personal vendetta.

One year ago, he was forced to partner up with the rookie cop Claris, and in the course of their investigations together he reencountered the A-class criminal known as Linda.
Recently, he's been moving independently of Claris more often...

His abilities are ice-based and too powerful for him to fully control. He keeps them repressed most of the time.
