Le Fantasque is rendered in a dynamic, action-ready pose atop a detailed deck-style base. Her long hair, tinted in deep navy with cyan highlights, flows behind her as if caught by sea wind. She wears a sleek, naval-inspired outfit that blends futuristic armor with traditional sailor motifs: a fitted bodice, a short pleated skirt, and thigh-high stockings with gold trim. Small rivet textures, a panel of plated armor along the shoulders, and tiny rigging elements add depth to the design. The paintwork emphasizes crisp line work, subtle gradations, and metallic accents on the armor and accessories, with a clear gloss on glossy parts to simulate glass and lacquer. Overall, the figure conveys a sense of motion, poise, and readiness for battle.

Le Fantasque is presented as the sharp-witted captain of a shipgirl squad in Senkan Shoujo R, a world where vessels awaken as young heroines and join fleets in defense of the seas. In her story, she leads with calm assurance, forging strategies under pressure and turning even hopeless battles into opportunities. Her background hints at a lineage of seasoned navigators, rigorous training, and a personal code that values crew safety as much as victory. Although she commands respect, she also forms deep bonds with her teammates, sharing jokes during long patrols and comforting others after close calls. The tale explores themes of duty, friendship, and the cost of leadership, culminating in moments of quiet resolve when the sea calms and a brighter horizon appears.
