Siren in a Moonlit Mansion (Anime Style)

An ethereal siren with flowing aqua hair and shimmering scales stands in a grand mansion hall. Rendered in vivid anime style, she stands on a polished marble floor with shallow water pooling around her ankles, chandeliers overhead, and moonlight streaming through tall windows. The walls feature sea-inspired decor—shell mosaics, coral accents, and portraits that blend ocean motifs with classic mansion aesthetics. She wears a pearl-white gown that swirls like sea foam, with translucent fins and sparkling sequins catching the light. A dramatic low-angle perspective emphasizes the opulence of the hall; color palette of deep blues, teals, and golds; crisp cel-shading, soft gradients, and ethereal lighting create a mysterious, otherworldly mood.
