The Dead Moon Circus headed by Zirconia and consisting of Hawk's Eye, Tiger's Eye, Fish's Eye, CereCere, PallaPalla, JunJun, VesVes and Nephrenia, is searching for Helios, the guardian of the Golden Crystal which, if in the hands of the New Moon, will turn his land, Erusion, into a land of darkness. However, the bad guys managed to lock Helios away, forcing him to take on the equinine form of Pegasus, who now lives in Chiba-Usa's dreams. To find Helios, the New Moon must attack the owner of the dream mirror Helios is hiding in, and it's up to the Sailor Senshi to stop them, in the beginning of the story.
