As Mizusawa begins a match against Yamaguchi Mioka, a distinguished school, the tournament officials discuss what to do concerning Arata's violation. Although Chihaya is able to defend her cards, she struggles to attack her opponent's. All the Mioka members place their cards randomly and move them frequently. Shinobu, drenched from the rain, arrives back at Ōmi Jingū and learns of Arata's situation. She threatens to forfeit the tournament if the officials don't let him play. Except for Chihaya and Tsukuba, the other Mizusawa members do well against Mioka. As the number of cards remaining decreases, Chihaya improves. Mizusawa wins. Sumire tells the team about Shinobu telling the officials she wants to compete against someone from Fukui. Chihaya deduces that it was Arata. As the team considers including Komano in the next match, Nishida suggests they leave him out.
