Kazui Mukuhara 椋原一威

A middle-aged man and the oldest prisoner in Milgram.

He is nonchalant, often voicing jokes to break the tension. Tall and muscular despite looking slim — he seems to have experience with some kind of martial arts. In groups, he portrays himself as a gentle, sanguine character, however during individual meetings with the prison guard, he is enigmatic and stares, as if he is scrutinising something.
