Dosu-Roku was a boy in his very late teens, he had a lazy eye, and a short quiff haircut. He had a pink shirt and a large black trench coat with a popped collar.
Dosu-Roku along with Masa and Manjiro had been killing the school rabbits for the fun of it when they were caught in the act Akira Fudo, who rescues the last surviving rabbit. Dosu-Roku mocks Akira as Manjiro knocked him to the ground, however when he refused to surrender the last rabbit and Manjiro began to attack him, he began to worry for him. When Miki arrived looking for Akira, Dosu-Roku tries to stop her from coming round the corner but is pushed out of the way and departs with the rest of the gang shortly after.
