A visiting princess is holding a ball to show off her nation's treasure, a beautiful jewel. Usagi disguises herself as a princess to invetigate whether this girl could be the missing moon princess. Nephrite also goes because he thinks that the jewel could be the Silver Crystal that Queen Beryl has been seeking. Usagi loves the ball and even gets to dance with Tuxedo Mask (who is also there looking for the crystal). However, Usagi an Tuxedo Mask are left dangling over the side of the balcony when Nephrite possesses the princess. Usagin and Tuxedo float safely to the ground using Usagi's parasol. Later in the evening, Tuxedo Mask visits sailor Moon on the balcony and kisses her under the moonlight. They both remember something like this from the past...
