Sailor Aluminum Siren

Away from battle she takes the human form of Reiko Aya, a disguise she uses to harvest Star Seeds; lose her temper, though, and she slips back into her real self without meaning to. As an Animamate her look copies the manga design almost exactly, parting ways in only two small details: she drops the second, longer necklace and trades the blue stockings for lilac ones.

Off the clock she comes across as sweet, scatterbrained, and perpetually hungry, forever snacking or daydreaming through assignments, a habit that grates on the far sterner Lead Crow even as the two remain genuine friends. The moment a fight begins, however, the charm evaporates and she turns coldly merciless.

She first appears at Sailor Iron Mouse's final warning, and once that failure is disposed of, Galaxia pairs her with Sailor Lead Crow to seek out genuine star seeds. Fronting as agents at the Ginga TV station, the two work side by side, having once vied for the rank of top Animamate. Siren eventually uncovers Sailor Moon's secret and comes close to killing her, only for the Sailor Guardians and the Starlights to intervene. Even after finding a powerful star seed and learning the heroines' identities, she never gets the chance to hand the news to Galaxia. Branded a failure, she politely insists the blame is not hers for failing to expect so many guardians, but when Sailor Tin Nyanko accuses her of lying about the seed, Galaxia strips away her bracelet and destroys her before her grief-stricken friend.
