Doubles 2 of the finals: Inui-Kaidoh pair vs Yanagi-Kirihara pair. Inui's best data and Kaidoh's Tornado Snake are ineffective against Rikkaidai's pair. Inui seems ready to give up, but Kaidoh uses Yagyuu's Laser Beam. Kirihara transforms into a demon, purposely aiming at Inui and injuring him severely. Kaidoh turns into a demon himself, but was stopped by Inui. Soon after that, Inui collapses, Seigaku forfeits the match, and Inui is rushed to the hospital. This episode is when Ryoma loses/lost his memory.
