Hideo Hoshino, a young boy, appeared at the first pitch ceremony for the Pacific League East-West competition, where he showed off his fastball and immediately attracted the attention of professional teams. He had hoped to join the Seibu Lions, but after losing a match to Mitsuho Idobata, a girl whose grandfather was the owner of the weak baseball team Musashino Wildcats, he ended up joining Musashino. Around that time, Hoshino's rivals who played against him at the National Boys and Girls Baseball Tournament also joined Pacific League teams.
