Ichirou Yamada 山田一郎

Eldest brother of the Buster Bros!!! Yamada trio, he is a former member of The Dirty Dawg and a manager of Yamada General Store (Yorozuya Yamada). There's not a single person from his generation who doesn't know his name.

Very affectionate, and hates those who bully the weak. A defender of justice who cannot abandon those in need. His hobbies are watching anime and reading every light novel he can get his hands on. Flies into an uncontrollable rage when made fun of for his hobbies. On bad terms with the Yokohama division leader, Samatoki Aohitsugi.
