Akitaru is a well-built young man with short, somewhat unruly dark hair, with the sides of his head being shaven. Akitaru also has small dark brown eyes. He is seen wearing bunker gear, which consists of a black tank top, buckled at the waist with a belt, which presses a middle part that's strapped to his shoulders, and dark pants. Those are later topped by a protective jacket, trousers and a helmet, which has a metal face-shield attached to it.
