Sailor Aluminum Siren is the second of the Sailor Animamates to appear. In the anime, Aluminum Siren is very polite, ditzy, and oblivious when off-duty, and is always eating or feeling hungry; once engaged in battle, however, she drops her flaws and becomes completely ruthless. Masquerading as Aya Reiko, she works together with Karasuma Akane aka Sailor Lead Crow.
