The ten Sailor Guardians have gathered for the final battle. However, the Queen of the Dead Moon, Nehelenia, attacks with the power of her "nightmares". While Helios uses his last ounce of strength to save the Earth, Usagi is drawn into Nehelenia's nightmare, but is encouraged by the strong heart of Tuxedo Mask. Joining forces with her fellow Super Sailor Guardians, she transforms into Eternal Sailor Moon. Finally, all "Eternalized" Sailor Guardians have gathered.
