Pretty Guardian Sailor Moon Cosmos

Released across two installments in 2023, this theatrical project functions as the concluding chapter of the Sailor Moon Crystal continuity, sometimes framed as its fifth season. Toei Animation and Studio Deen handled the animation together, continuing the partnership formed on the preceding Eternal films, while Naoko Takeuchi oversaw the work as chief supervisor. Tomoya Takahashi stepped in to direct, taking over from Chiaki Kon, and Kazuyuki Fudeyasu returned to write the script. The story resumes directly from where the Eternal movies left off and covers the manga's final act.

Peace among the Sailor Guardians shatters when Shadow Galactica, a hostile force led by Sailor Galaxia, arrives to hunt down the Star Seeds that give the Sailors their power. Operating from a broadcasting station called Ginga TV, Galaxia's agents strike at the heroines one after another. The mysterious child Chibi Chibi appears at Usagi's side, and the traveling idols known as the Three Lights are revealed to be the Sailor Starlights, warriors searching for their lost ruler, Princess Kakyuu.

As Galaxia claims the lives of allies and turns fallen Guardians against the group, Usagi is pushed toward a confrontation with Chaos, the ancient evil driving Galaxia. Chibi Chibi's true nature ties her to Galaxia's own Star Seed and to the enigmatic Sailor Cosmos, a distant future incarnation of Sailor Moon herself. The battle carries the fate of every star in the galaxy, and its resolution leads at last to a wedding between Usagi and Mamoru, closing the saga on a hopeful note.

The two films reached Japanese cinemas on June 9, then June 30 of 2023, and a home video edition followed that December before Netflix carried them worldwide in August 2024. Yasuharu Takanashi, composer for the earlier Crystal seasons, scored the movies, with singer Daoko performing the main theme Moon Flower. Casting drew attention for reuniting long serving voice talent and adding fresh actresses for the Starlights, while live action Sailor Mars performer Keiko Kitagawa was tapped to voice Sailor Cosmos. An extended promotional campaign of character trailers and recap videos ran for months ahead of each release.
