Eiichirou Sharaku

Eiichirou Sharaku is the older brother of Eijirou and Mikage Sharaku. Like his father and younger siblings, he is a martial artist and trainer and helps run Rakuei Gym.

Appearance
Eiichirou is described as a squat man, but only so because his bulging muscles are disproportionate to his taller-than-average height.

Amphisbaena Arc
Eiichirou asks an assistant about the whereabouts of his younger brother, hoping that his slacker sibling is not picking fights in the street as he often does. Unbeknownst to Eiichirou, Eijirou is in fact getting into a fight outside, but only to protect Mairu Orihara from the Amphisbaena thugs trying to abduct her.
