Yoshihito's younger brother. He's always looking out for Yoshihito, who he adores. Because their parents have always worked long hours and Yoshihito is quite clumsy and absent-minded, he learned to manage the household himself as he grew up. He's also friends with Wataru, and butts heads with Ryousuke in his defense. He turns out to have a crush on Wataru, who seems to reciprocate.
