The first episode recaps the arcs of SM, SM R, and SM S. The second episode follows Haruka and Michiru aboard a cruise ship. They clash with a SuperS adversary, choosing to hand the threat over to the classic Sailor Team. (This explains why the outer Sailor Team is absent this season.) In episode three, Chibiusa spots a classmate turned monster, and teams up with the Sailor Team to battle her in a vampire castle for the final showdown.
