Shuuya Kano

Kano is a young man who is part of the Mekakushi Dan. He outwardly has an unfocused, aloof personality and always has a smile on his face. Because he teases Marry, Momo, and Kido a lot, he's often considered to be a flirt, but when it counts, he's worth relying on. His actual personality, which he hides behind his ability the majority of the time, is quite subdued and mature.
