Usagi decides that if she really is the moon princess then she should start acting like one. She and the other girls enroll in a princess training seminar (which is really just a trap for Sailor Moon). Usagi does horribly on all the exercises and fails along with Rei and Minako. After the ""graduates"" are turned into wax statues, the head mistress turns into a monster and attacks the Sailor Warriors under Kunzite and Endymion's supervision. The Sailor Warriors manage to defeat the monster when Kunzite and Endymion start to argue. They escape before Sailor Moon can use the Silver Crystal to heal Endymion's brainwashing.
