Aim for Ten Billion Yen ￥ The Hero Wars Curtain Rises!.A Hero Wars tournament is announced offering a grand prize of 10 billion yen, providing Kaito with just the opportunity needed to clear his debt. After Mitsuo explains the rules to Kaito and Fukuta, Kaito finds he needs to pay a 10,000 yen entry fee to enter. Meanwhile, Mitsuo receives a threatening e-mail telling him not to enter the Hero Wars if he doesn't want his mother to find out he had been playing Hero Battles when he wasn't supposed to. Following Fukuta's mouse Platina, Kaito discovers the culprit behind it is his teacher, Takeda, who has grown tired of students ignoring his lessons. Kaito challenges Takeda to a Hero Battle, pitting his Enter the Gold against Takeda's Magnum Teacher. Kaito is put under pressure as Takeda uses his own wages to fuel his battle money gauge and provide ammunition for his projectile attacks. But as Kaito expresses his desire to enter Hero Wars with Mitsuo, Mitsuo helps Kaito solve Takeda's trivia attacks and win the match, which also secures his place in the Hero Wars. As Kaito gains a new appreciation for studying, Takeda becomes more confident in his teaching.
