Lyrica Hubert was a transfer student at Chibiusa&#039;s school. She was a very pretty girl who was popular with her schoolmates, and supposedly the daughter of an ambassador, but was actually an enemy. In the anime, she was an innocent girl under the influence of a Lemures from the Dead Moon Circus, but in the manga she was a vampire with no affiliation to the other enemies of the Sailor Senshi.

The first episode is a summary of SM, SM R and SM S, the second episode is about Haruka and Michiru on a cruising. They fight one of the SuperS enemies and decide to leave this villains to the classical Sailor Team. (That's an explanation why the outer Sailor Team doesn't appear in this season.) In episode 3 Chibiusa uncovers one of her classmates as a monster and fights her with the Sailor Team in a vampire castle.
