Yajima Yuusuke

The second son of the Yajima family.
Stubborn and unyielding, Yuusuke won't budge once he's set on something. He's a serious man who absolutely lives for his job- which he's good at- but is totally useless in matters pertaining to his private life. He's self-conscious about the fact that his "professional self" and "home self" are wildly different, so he doesn't want his peers (especially his family) to see him at work. Incredibly short-sighted, Yuusuke can't see anything without his glasses.
