Fire Up ¥ Kaito Gosho's Intensive Training!.Sennen appears before Kaito and the others, explaining how he protected their memories of Nagare from being rewritten and suggesting Kaito undergo training in order to become stronger. Shishio Torai, a delinquent with a crush on Ai, offers to help Kaito in this regard, though it all proves pointless since he isn't using a Hero Suit. Afterwards, Kaito and co. are invited to a 'Hero Wars Seminar' by Kasumi Kamimaki, who is soon revealed to be a scam artist who had conned many victims. Angered by this, Kaito challenges Kasumi to a Hero Battle against his Hero Suit, Trick Suit. As Kasumi uses various tricks and cheats to put his opponent at a disadvantage, Kaito, spurred on by the support of the scammed victims, recalls Shishio's training and manages to win the match, after which Kasumi is arrested.
