Mamoru is about to leave to study in the United States but, as he is saying goodbye to Usagi, he is attacked and his body crumbles away, leaving only the Golden Crystal in its place, which is taken by Sailor Galaxia, the leader of a new group of villains known as Shadow Galactica. Usagi is shocked to see this and faints, but later blocks this memory and thinks Mamoru has arrived safely to the U.S. A new group of idols called the Three Lights comes to Tokyo and become students at Usagi's high school. Chibiusa returns to Crystal Tokyo. Usagi finds an incense burner in a park and keeps it in her home. Sailor Galaxia and her servants, the Sailor Animamates, destroy the Inner Senshi as well as Phobos and Deimos, one by one, taking their Sailor Crystals. Two Animamates are killed by the Sailor Starlights, who are revealed to be the true identity of the Three Lights, while a third Animamate is defeated by Eternal Sailor Moon. Usagi remembers what happened to Mamoru with the help of the Starlights. A new student named Nyanko Suzu arrives to Usagi's high school and tries to befriend her, but Luna and Artemis sense in her a power similar to theirs. Princess Kakyuu, the leader of the Starlights, emerges from an incense burner that Usagi has been taking care of.
Suzu reveals she is an Animamate from the same planet as Luna and Artemis, and attacks them as well Diana, who has just arrived from the future to help but fails to steal their Star Seeds and the Starlights force her to retreat. Galaxia eliminates her for her failure. Usagi meets Kakyuu, who explains that Galaxia has been destroying planets and stealing Sailor Crystals before reaching Earth and the Silver Crystal. Usagi, Kakyuu, Outer Senshi, and the Starlights travel to the Galaxy Cauldron, the birthplace of all life and stars in the Milky Way, located at the center of the galaxy, to get Mamoru and the Inner Senshi' Sailor Crystals and revive them.[1] Upon arriving, they meet Sailor Lethe, who brings Luna, Artemis, and Diana to kill them and to take their Star Seeds, which are as powerful as Sailor Crystals. Lethe attacks Usagi and the others but is stopped by her twin sister, Sailor Mnemosyne. Usagi realizes her Crystal is the source of all wars and asks Lethe and Mnemosyne to kill her, but the twins are moved by Usagi's sacrifice and let her go to Galaxia. However, Sailor Chi and Sailor Phi, Galaxia's closest servants and leaders of the Animamates, appear and kill Lethe and Mnemosyne with their powers, and take their Sailor Crystals. Sailor Saturn shields herself, as well as Usagi and Kakyuu, but cannot protect the Starlights, who are still unconscious in the ground from Lethe's previous attack.
The Starlights die as a result of Sailor Phi and Sailor Chi's attack, and their Sailor Crystals are taken too. As they make their way to Galactica Palace, Usagi, and the others destroy one last Animamate, however, the Outer Senshi would be killed by Sailor Phi’s attack and Kakyuu would be killed in action, and Usagi would destroy Phi and Chi and destroy the Eight Solar System Guardians, who are under Galaxia's control. Once inside the Palace, the battle between Usagi and Galaxia takes place. Usagi finally meets Chaos, the being who failed to become a star and who has sent incarnations in the forms of Metaria, Wiseman, Pharaoh 90, and Nehelenia to reach Usagi and her Silver Crystal. Galaxia intends for Usagi and Chaos to destroy each other so that she alone remains the most powerful being in the Milky Way, but she is killed by Chaos. Usagi uses all her power and throws herself into the Cauldron to seal Chaos. Within the Cauldron, Usagi meets Mamoru and her friends, and asks Guardian Cosmos, the guardian of the Cauldron, to send them all back to Earth and their normal lives and Usagi and Mamoru would marry.
1. The difference here is that Galaxia did not have a chance to destroy the Earth and the Outers did not go to their own planets and joined Sailor Moon in the Zero Star Sagittarius.
