Sailor Moon Eternal

A solar eclipse suddenly happens in the month of April. As the moon covers the sun, Usagi and Chibiusa meet a Pegasus named Helios, who's looking for two "chosen maidens" to help break the seal of the Golden Crystal. He appears in Chibiusa's dream, seeking her help. Meanwhile, a mysterious group called the Dead Moon Circus appears in Juban. Their goal is to scatter nightmare incarnations called Lemures across the world, obtain the Legendary Silver Crystal, rule the Earth and Moon, and eventually the universe. Chibiusa, who was called a "young maiden" by Helios, begins developing feelings for him. Mamoru distances himself from Usagi, fearing that being near her will put her in danger.

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". Helios uses his last ounce of strength to save the Earth. Usagi is drawn into the 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.
