Hishima has dark grey hair that is longer on the top and short on the sides, and grey eyes. He wears some basic glasses. He wears a black jacket with a dark shirt underneath. He wears dark grey pants with light grey vertical stripes, black shoes, and a black glove on his right hand with a golden diamond-style bracelet on top of it.
Hishima is not serious about the Reapers' Game and rarely participates in its management, claiming his heart is not really in it. He is intelligent and a stoic,but also cynical, sarcastic and stubborn. Somewhat of an odd Reaper out, he’s a man of mystery: even his comrades can't discern whether he has some sort of ulterior motive.
