Luna grows jealous of Artemis' alleged love with a nun, though Artemis says it is a misunderstanding. Not long after, a gray kitten with a crescent moon mark on her forehead appears. She proclaims that she is Artemis' daughter, much to Luna's disgust. Even Minako Aino is angry at Artemis for not telling her that when she got a phone call from Usagi about the event. Meanwhile, the nun is targeted by Tiger's Eye. After a brutal battle, it is revealed that the gray kitten is Diana, Luna and Artemis' daughter from the future Crystal Tokyo and Chibiusa's guardian cat, as well as Artemis was actually into the chapel the nun lived in, thinking about marrying there.
