Description
Yayoi, also known as Promethium II or La Andromeda Promethium II, is the Millennial Queen dispatched from the planet La Metal to Earth every thousand years. Her mission entails secretly ruling Earth through an underground organization. Assuming the identity Yukino Yayoi on Earth, she works as Professor Amamori's private secretary.
In the Queen Millennia TV series narrative, Yayoi is the princess of La Metal destined to become the next Millennial Queen. She ultimately betrays her home planet and the current Millennial Queen to protect Earth and a young boy named Hajime, allying with her older sister Selen to prevent Earth's annihilation.
Her Earth living arrangements differ across adaptations: residing on the second floor of an elderly couple's ramen shop (who adopted her) and owning a tiger-striped cat in the anime TV series and manga, while occupying a high-class apartment and working as a schoolteacher alongside her secretarial role in the anime film.
Within the Queen Millennia movie, Yayoi opposes the character Lalela's plan to exterminate humanity to secure eternal spring for La Metal's inhabitants. This contrasts with the TV series, where she resists pressure from her mother, Promethium I, to destroy humanity for La Metal's cyclical traditions. The movie concludes with Yayoi sacrificing herself to weaken Lalela by shooting her with a pistol.
Yayoi's narrative intersects with the broader Leiji Matsumoto universe through her identification as the mother of Maetel and Emeraldas in *Maetel Legend*, *Space Symphony Maetel*, and *Galaxy Express 999*. Initially a compassionate queen with a human body, she later embraces mechanization to avoid aging and illness. This transformation gradually erodes her humanity, particularly her capacity for love, leading to regret. Her mechanized self becomes the primary antagonist opposing her daughters. Though Maetel seemingly kills her in *Space Symphony Maetel*, her consciousness persists, culminating in her final destruction during La Metal's downfall in *Galaxy Express 999*.
A continuity ambiguity exists regarding whether the Yayoi/Promethium II from *Queen Millennia* is the same character as the Promethium in Maetel's stories, as these narratives may exist in separate continuities.
