Along the way, he encounters some unlikely allies, such as a small elf named Puck, and Isidro, a young thief looking to learn swordsmanship from the former mercenary. As the ragtag group slowly comes together after having decided to join Guts in his quest, they will face incredible danger unlike anything they have ever experienced before.

Arato Endou and his faithful hIE, Lacia, have come together once again to show the world that artificial intelligence, no matter how brilliant, can be shut down safely.

Among them are Snowdrop, a rampant hIE hellbent on devouring Higgins, and Methode, a hIE who seeks vengeance against Lacia. The world's super-intelligent AIs unanimously decide to terminate Lacia, whom they deem a threat to humanity. With limited time and the odds stacked against them, will Arato and Lacia be able to truly join together in a society where humans and hIEs can coexist peacefully?

Like the R Season, Sailor Stars is divided into two parts: The first part resolves some conflicts from the SuperS season, and sees the return of the Outer Senshi, Haruka, Michiru, Setsuna, and Hotaru (now reborn as a child). In the second part Usagi bids farewell to Mamoru, who is going to America to study. At the same time, the Three Lights apper, an idol trio consisting of three boys, Seiya, Taiki, and Yaten. The new enemy is Galaxia, a woman who desires to rule the entire galaxy by collecting the Star Seeds of humans. Three new Senshi appear, the Sailor Starlights, who have their own reasons to stop Galaxia, but without Sailor Moon's help.
