Guardian Cosmos

Small and delicate, Guardian Cosmos floats inside a circular halo of light, her hair spilling far down her frame. She wears a sheer, balloon-like gown strung with beads, a tiara sits on her head, and she carries a staff. The whole design evokes the fairy godmother familiar from children's fairy tales and animated films.

She stands among the manga's most enigmatic figures, devoted wholly to guarding the Galaxy Cauldron and granting the wishes of those who reach it. Though she carries the Cosmos name, she has no tie to Sailor Cosmos in the present, and her attention stays fixed on that ancient caretaker role.

Unlike the guardians assigned to individual planets, Guardian Cosmos watches over the Cosmos Crystal and the Galaxy Cauldron, the wellspring of all star life. Long ago she answered Queen Serenity's plea and granted the reincarnation of her lost daughter, Princess Serenity, after the queen carried her Moon Crystal to the Cauldron. Her defining moment arrives when Eternal Sailor Moon plunges into the Cauldron to save her friends and confront Chaos, which has fused with it. Expecting to dissolve like everyone else who has fallen in, Usagi instead wakes within, reunites with the others, and is greeted by the tiny spirit. Guardian Cosmos lays out a choice: begin a fresh history of the stars, or stay in their present star forms. Usagi asks to go back to the life she and her friends shared, however hard the road, so that they can keep living together. The guardian remarks that this echoes a woman who once came to the Cauldron in her finished star form, clutching a Star Seed as radiant as Usagi's. As the Guardians are wrapped in light and carried away, Usagi tries to ask about Chaos but is pulled out before she can finish. Guardian Cosmos answers to the empty air that the Chaos Seed and Guardian Chaos have both melted into the Cauldron, yet may one day return. She is the last new character introduced in the manga's main story, and her scene closely mirrors the Disney film The Black Cauldron, where cauldron-guarding witches reward a hero's self-sacrifice with a wish.
