History
Sailor Mermaid protects the planet Mermaid, the world where Sailor Aluminum Siren originated. Kou Yaten, speaking in his human form, mentions her in Act 54 Stars 5 together with the guardians Chuu, Coronis, and Mau, all rightful protectors of the planets that produced Galaxia's Animamates. Aluminum Siren killed her and seized her Star Seed as a way to earn standing with Sailor Galaxia.
