Sonico is depicted in a bright marine ver. outfit that blends fan-favorite charm with seasonal flair. Her long pink hair cascades down her back, styled with soft curls and a few wind-tousled strands to reflect shore breezes. She wears a navy blue and white swimsuit with subtle gold piping and tiny anchors as accents, complemented by a short cropped jacket and a light, translucent scarf that catches the light. Her expression is cheerful and energetic, capturing her signature enthusiasm. The base evokes a sunlit coastline with gentle waves and a stylized sea-steady stance to support the dynamic pose. The finish is glossy and smooth, highlighting sculpted lines and outfit details.

In the SoniComi universe, Sonico is a multi-talented idol who loves the sea. For this Marine Ver., she heads to a coastal festival where the stage is built on a floating platform. Between performances, she chats with fans, signs autographs, and unfurls a spirited song that echoes across the water. The design imagines her as both performer and explorer, mixing music with maritime whimsy. Her costume and pose suggest movement and confidence, as if she just stepped off a sunlit boardwalk and into the spotlight. This figure captures her upbeat personality, adventurous spirit, and affection for the ocean.
