As Yuya's group arrives at Duel Academy, Yuya, Gong, Sylvio, Crow, and Moon Shadow are captured and forced into a Survival Duel Battle Royal against Obelisk Blue students. As Moon Shadow heads off on his own, he comes up against a mysterious opponent who turns both him and several Duel Academy students into cards. While Yuya and Gong learn from Moon Shadow's last message that there is another duelist besides the Duel Academy students, Sylvio is attacked as well. Meanwhile, Aster catches up to Yugo and theorizes who might be behind Rin's strange behavior.
