Fire Up ¥ Kaito Gosho's Intensive Training!! - S1.E9

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.
