While Naoki, Kamui, and Miwa train, Kai and Misaki struggle with doubts from Aichi and Kourin. Leon reassures Misaki, restoring her faith in Kourin, who then trains her. Meanwhile, Kai remains lost without the Blaster Blade Seeker card despite help from Jillian and Sharlene. Leon shares his history of accepting Void's power and questions Kai's desires. Kai finally decides to save Aichi at all costs, returning to his Kagero deck. The group completes their training and departs the island. Upon returning home, it is revealed that Aichi offered Leon and Ren positions as Quatre Knights. Both declined the offer, choosing neutrality and leaving the task of saving Aichi to Kai and his friends.
