The semifinal game against powerful Maguro draws near as everything goes wrong. Imadoki is to be expelled; Nanamaru must learn a pitch that seems impossible to learn; and to save others, gentle Bunan must walk into deadly danger alone.

Nanamaru shocks Polaris with her Magic pitch but her shoulder worsens with every throw. The Bemars are overwhelmed by Kirei's Fire Windmill pitch but they fight on. As the battle rages, the fate of Hatsumori Park hangs by a thread.
