Bonchuu

A rebellious and absurdly strong kid. He went to the same Leader nursery school as Takeshi. When the teachers gave Takeshi the notorious Leader Badge instead of him he got extremely resentful. He maintains that sentiment to this day. One day when he was returning from school he saw his house burning down with his sister inside. Since he couldn't save her, he came to the conclusion that only strength matters in this world and he swore to himself to be the strongest person that has ever been so that something like this can never happen to him again.
