Power vs. Ninja Arts! A Fierce Competition!.Gao and his friends witness a confrontation between Team Kisaragi and Team Seifukai. Gao attempts to intervene, but the standoff is broken up by Seifukai's deputy leader Totsuo Doai. Later, Doai tells Gao about how Seifukai's leader, Genma Todoroki, and his deck have gone missing. In addition to recommending Gao to join Seifukai (although Gao declines his offer), Doai says that he will be taking Genma's place in the upcoming match against Team Kisaragi. Then, the ABC Cup continues with the Buddyfight between Team Kisaragi's Zanya and Team Seifukai's Doai as Gao and his friends watch. Despite Doai's powerful attacks, Zanya outmaneuvers him and eventually wins. After the fight, Zanya overhears Magoroku talking about having Genma's deck. Zanya orders his buddy monster Nanomachine Ninja, Tsukikage to secretly follow him, not fully knowing that Magoroku is the person behind Genma's disappearance.
