Kazui Mukuhara

A middle-aged man, the oldest prisoner in Milgram. He is calm, always playing tricks to make the atmosphere more relaxing. He is tall and thin, but muscular too. Somehow, it is as if he has experience with martial arts. In the group he acts as a calm and optimistic person, but with the jailer, particularly during interrogations, since he keeps his eyes wide open as if analyzing something, his true nature appears.
