The Lover of Princess Kaguya

Luna develops feelings for Kakeru Ohzora after he pulls her out of danger. His close friend Himeko Nayotake is preparing for her first spaceflight when a comet calling itself Princess Snow Kaguya arrives and upends everyone's plans. Kakeru's condition worsens as the object nears the planet, prompting the Sailor Guardians to look into the approaching threat.

The events land in December, near the close of the Infinity arc, though the piece sits awkwardly beside the main plot. Super Sailor Moon appears and the other Senshi still wear their heart-shaped brooches, even though obtaining the Holy Grail and beating Pharaoh 90 happened the very night the Outer Guardians departed until the Dream arc's finale. It opens with Kakeru snatching a falling shard from the sky, which draws a menacing voice that marks him as a target.

Setsuna, Michiru, and Haruka run late to a shared birthday celebration at Fruits Parlor Crown thrown for Minako and Makoto, where Ami, Rei, Usagi, Chibiusa, and Mamoru gather while Motoki and Unazuki wait on them. Diana arrives happy to have made it, but Luna pins the cats' tardiness on Artemis, who fires back that she always makes him fetch her. Snow begins to fall as they celebrate. On a separate day, guilt-tripped into collecting Artemis herself, Luna reaches the big intersection where a pack of children had once cornered her and stuck bandages on her crescent mark. It happens again, and while fleeing in a panic she stumbles into the road, glimpses an oncoming car, and loses consciousness.

The chapter introduces Kakeru Ohzora, Himeko Nayotake, Princess Snow Kaguya, the Snow Dancers, and Luna's human form, along with the phrase Pluto Planet Power, Make Up and the attack Pink Sugar Tuxedo Attack. To prepare the material, Naoko Takeuchi visited the Kennedy Space Center for research. The story was adapted into Sailor Moon S: The Movie and afterward became the basis for the musical Kaguya Hime's Beloved.
