It's every high school baseball team's dream to go to the legendary Koshien Stadium Tournament. For the first time in years, Seido High School has a chance—star player Gorilla Matsui has finally given the team an opportunity to succeed. Most delighted at this prospect is Principal Kocho. However, the Head teacher reveals to him that the first game will be played against the Gedo High School, infamous for brutally killing all their opponents. Kocho instantly loses all hope, both for his students' lives and of winning the tournament.
