Vegeta continues his fight against Tamagami Number Two. Meanwhile, Majin Duu is engaged in battle against Tamagami Number One but takes a break to ask Dr. Arinsu for chocolate. Majin Kuu sets out to retrieve it. At the same time, Neva intervenes in the battle and performs a ritual to strengthen Two in the duel against Vegeta. Duu continues to retreat from One, while Degesu and Gomah observe the events from a safe distance, questioning Arinsu's true intentions.

Kuu brings back the chocolate, and after Duu consumes it, he defeats One with a powerful energy wave. Before his defeat, however, One presents Duu with a mathematical problem. With Kuu's help, Duu solves the riddle, obtains One's Dragon Ball, and hands it over to Arinsu. The group moves on, while Degesu tries to reassure Gomah that Arinsu is collecting the Dragon Balls to protect them from Goku and his friends. Gomah, however, remains suspicious and suspects Arinsu has his own plans.

Back on the battlefield, Two gains the upper hand against Vegeta, forcing Vegeta to transform into a new, more powerful form. Bulma explains that Vegeta achieved this transformation through intense personal training. With his newfound strength, Vegeta defeats Two and is also confronted with a mathematical problem. After solving it correctly, he obtains Two's Dragon Ball.

The scene shifts to the group preparing for a new objective. Glorio inspects the aircraft and determines that it needs repairs. Panzy fixes the damages, and the group sets off for the First Demon Realm. Degesu and Gomah watch from afar as the heroes head to their destination. At the end of the episode, Gomah reveals to Degesu that he has a plan.
