Melusine stands gracefully, captured in a dynamic, water-swept pose that suggests you're about to step into a festival by the sea. The Last One Prize edition emphasizes a sparkling finish on her translucent blue tail, with sculpted fins and delicate shading that evoke sunlight dancing on waves. She wears a festival-inspired outfit that blends marine motifs with summer attire: flowing robes, sea foam accents, and tiny pearl-like beads. Her hair is styled in loose curls, adorned with shell accessories, and a small pedestal shaped like breaking surf completes the display. The paintwork highlights contrast between glossy water surfaces and matte skin tones, bringing a lifelike, shimmering presence to the shelf. The overall silhouette is elegant, with careful attention to balance and pose, making her a standout centerpiece in any Fate/Grand Order collection.
