Kenka no Gokui 5.

As graduation approaches, Tatsuya—the right-hand man of Kiwakou’s strongest fighter Momo—leaves school. Spring draws near, but Haru and the first-years live only for today’s fights. Their next opponent: Gakki, the strongest fighter from Rangaku High and Momo’s lifelong rival. A long-standing ceasefire shatters as the two schools clash head-on in a 4-on-4 one-on-one battle, pride against pride.
