"First kiss...kiss me, Michael."
-Elizabeth mistaking Lita for her boyfriend
Serena sees Darien giving Andrew's sister Elizabeth another ride on his motorcycle. Elizabeth asks Serena if she and Darien have had their first kiss yet. She is in love with someone named Michael, but hasn't kissed him yet. Amara and Michelle note that she possesses a Pure Heart and could be targeted by the Heart Snatchers.
Doctor Tomoe targets someone who seeks their first kiss, and, naturally, targets Lizzie, so Kaorinite sends a Daimon pod into her vacuum, turning it into a Daimon named Osoji, which extracts Elizabeth's Pure Heart and runs away. Sailor Uranus and Sailor Neptune attack her, causing her to lose the Pure Heart, which falls onto a garbage truck. Serena, Amy, Raye, Lita, Mina, Luna, and Artemis find Elizabeth in a trance due to her Pure Heart being taken, and tries to kiss Lita, so Raye stuns her with a scroll attack, and they all seek out Osoji.
Serena and Darien ride to the junkyard on Darien's motorcycle reach the junkyard where Osoji finds the Pure Heart. Sailor Uranus and Sailor Neptune arrive and fight Osoji. Serena transforms into Sailor Moon to fight her. She is at a disadvantage until Tuxedo Mask attacks Osoji, and Sailor Moon destroys her. Sailor Uranus holds Sailor Moon back while Sailor Neptune examines the Pure Heart, and, seeing it is not one of the three crystals, gives it to her to take back to Elizabeth.
Afterwards, Serena and Darien talk on the balcony, and Serena yells at Darien because he can't remember their first kiss.
