Just when Gao defeats Duel Sieger "Spartand", Genma evolves it into its ultimate form: Duel Sieger "Tempest Enforcer". After attacking Gao with "Tempest Enforcer" three times, Genma reveals that he was once friends with Gao's brother Yota. They met while in the hospital where a young Genma became interested in Yota's comics about the "Mighty Sun Fighter". Genma was inspired by the message of the Sun Fighter, thinking it meant to be a strong leader for others to follow, which shaped him to the person he currently is and claiming the title of "Mighty Sun Fighter" to himself. However, Gao refutes him by saying the real purpose of the Sun Fighter is to serve as a role model to motivate others to follow their dreams. As Genma realizes his misunderstanding, Gao uses the card that Yota left (which is revealed to have originally belonged to Genma): Sun Fist, Sunshine Impact. Attacking together with Drum Bunker Dragon, Gao destroys "Tempest Enforcer", which, due to its negative effect, causes Genma to instantly lose, thus making Gao and Team Balle du Soleil the winners of the ABC Cup. In celebration of this victory, Gao and his friends have a party and are later joined by Genma, who gives Yota's comics to Gao and pays his respects to Yota. Despite the cheery atmosphere, Drum is feeling unsatisfied with his overall performance and tries to think of ways to become stronger...
