Sonico stands gracefully in a mermaid princess pose, her long pink hair flowing as if stirred by a gentle sea breeze. The figure captures her signature cheerful face with bright eyes and a soft smile, framed by a delicate seashell tiara. She wears a shimmering aqua-blue bodice and a scale-textured mermaid tail that ends in translucent fins, suggesting motion and underwater light. A translucent wave base supports her, with pearl-white accents and tiny bubbles carved into the surface. Subtle metallic sheen highlights on the tail and accessories give depth under display lighting. The overall color palette blends pink, coral, turquoise, and pearlescent white for a whimsical sea fantasy aesthetic.

In the SoniComi universe, Sonico is the ever-optimistic guitarist and model whose adventures expand beyond stage lights into enchanted seas. This Mermaid Princess incarnation imagines Sonico trading the roar of crowds for the hush of tides, guiding sea creatures and defending a shimmering underwater kingdom from driftwood storms and sneaky pirates of the deep. The figure merges her cheerful, friendly persona with regal mermaid traits: a crown of seashells, coral accents, and a tail that persuades sea magic to glow softly. Her persona embodies curiosity, kindness, and a playful sense of wonder that resonates with fans of all ages.
