Usagi and the other girls regain their memories of their lives as Sailor Senshi, and their battle with The Dark Kingdom. Now, two aliens, Ail and Ann, are stealing energy from humans and feeding it to their sinister Makaiju Tree. In the second arc, a mysterious pink-haired girl, Chibiusa, shows up. She's looking for the ginzuishou, and the evil Black Moon Clan are after her.
