In the anime, it's presumed Sailor Galaxia stole the star seed from Sailor Aluminium Siren, so without it, she'd either have to perish or serve her in order to survive (getting her powers from Galaxia and being brainwashed in the process thanks to the bracelets). In the manga, she betrayed her planet and received the power of the true Sailor Senshi by Galaxia afterwards (once more, using the bracelets as a router).
