Quote: We don’t stop playing because we grow old; we grow old because we stop playing.

Second son of the Yamada household and Buster Bros!!!. One of the bosses of Ikebukuro. A strong fighter. He idolizes Ichiro, who is beloved by everyone. He grew up watching his big brother's back, and thus became a delinquent like him.

Just like Ichiro, he hates bullies. Due to his big brother's influence, he is well-versed in anime and light novels. Anyone who makes fun of his big brother will be crushed out (or will be devoured). Always fights with his younger brother, Saburo Yamada.
