The Return of the Ninja Master

A tournament is being held again at Card Capital, but it is now a team fight due to the large number of participants. Team Q4 fights and moves all the way up to the final round, with Kai not participating in the team fight. Q4 discovers their opponent to be Team Overthrow which consists of Miwa, Yūta, and Katsumi, who is dressed up as Ninja Master M, since the costume was donated to him by M, since he decided to not participate in tournaments anymore. In the first round, Katsumi faces Misaki and completely loses due to his deck being full of grade 3s. The second round features Kamui and Degozaru's secret weapon, Princess Maiden, who is actually Emi, who wanted to participate in the tournament. Because of Kamui being unwilling to give his all against Emi, she defeats him using her Bermuda Triangle/Oracle Think Tank deck. Now it is Aichi's turn, and his opponent is none other than Miwa!
