In his first appearance, he also wears a golf glove.
A very calculating and arrogance individual, Akira is a prideful and clever schemer.

In public, Akira behaves in friendly and easy-going way, but quickly drops this facade if the situation suits him.

Upon finding out that Sayama is part of The Good Dôji Club, Akira doesn't hesitated fighting her. However, his arrogance prevents him from noticing Sayama's hold on him.
