Melvin and Molly each think that the other one is cheating on them. And we find out that Melvin makes Molly fried shrimp. And it is up for Serena and Rei to save their love. Rei comes up with an idea to get Molly and Melvin back together by entering them into a contest for opening of Heart World and the winner of this contest gets to light the big heart. The Big Heart Light is chosen to make a Daimon Heart Snatcher. Amara and Michelle also enter this contest, but only for the show. The First round is where they have to find their partner's hand. Amara wins. But Melvin chooses the wrong hand (with the bandaid). And it shows, that he can remember the details about her. The 2nd round is a Three-Legged Race. 3rd is something with a pan and an egg. 4th round is the Karaoke round. In the Karaoke round Melvin sings the wrong song. The 5th round is the test of trust. And the final round is the test of affection. The audience decides in the round. Amara and Michelle drop-out and reveal the contest. They win the contest, and when they try to light the Big Heart Light. The Heart Snatcher, Die Heart attacks them. Melvin takes the hit of Molly. And it's time to Transform! Time for Sailor Moon and the Sailor Scouts fight! Die Heart takes the Melvin's Pure Heart Crystal out and 5 guys appear from a spell of Die Heart.
