Juumonji Kazuki is the head of the Ha Ha Kyoudai, which consists of Kuroki Kouji, Toganou Shouzou, and himself. Kazuki was first introduced to us as bullies of Sena's high school life. On Sena's first day, he was already forced by the Ha Ha Kyoudai to buy them bread. He had failed his errand because the bread at the shop was all sold out, which led to Sena being chased by them. This chase was also what led to Youichi spotting Sena's fast legs. Although in the beginning, Kazuki and the Ha Ha Kyoudai were just bullies, they ended up joining the Devil bats as defensive linemen. He is referred to as one of the Huh-Huh Brothers by Hiruma although not really related.
