An average-looking man of moderate height and unassuming physique, he has short, unkempt brown hair and green eyes.
As a Lieutenant he wore a standard Shinigami Shihakushō with a lab coat draped over it, with his Lieutenant's badge is placed at his right arm.
He currently wears a long-sleeved Captain's haori, reminescent of a lab coat, over his fairly standard Shinigami Shihakushō.
A responsible and diligent worker, Akira displays great loyalty and devotion to his Captain, Kaoru Shōki. Additionally, he is a very polite and friendly individual, his politeness extends to even to his opponents, apologising as he felled one such opponent.
He has a noticeable uncertainty in his abilities, which is especially shown after his promotion. He frequently deems himself unworthy of captaincy and immediately requests Kaoru Shōki to be reinstated as the 12th Division Captain upon her return.
