Positioned in a dynamic, forward-leaning stance, Katsushika Hokusai stands atop a sculpted wave base that curls beneath her feet, echoing her ukiyo-e heritage. She wears a flowing kimono-inspired outfit with layered sleeves, an obi tied at the waist, and decorative wave motif trim in shades of deep indigo, sky blue, and white. The fabric appears to ripple with every slight turn of the figure, catching light to reveal subtle gradient shading from navy to cerulean. Her hair is styled in a traditional updo with a lacquered hairpin, and a calm, confident expression sits on her face. In one hand she grips a slender brush that doubles as a weapon, while the other hand is extended as if directing a painted current. The base features intricate print-like patterns and small sculpted motifs referencing famous ukiyo-e subjects, giving the piece a refined, museum-like presence on a shelf.

Katsushika Hokusai in Fate/Grand Order is presented as a brilliant, restless artist sent forward in time to confront threats with the quiet ferocity of a master painter. Born from a long line of painters, she values beauty, truth, and the freedom to depict the world as it could be, not merely as it is. In the game she channels her artistry into combat, turning brushstrokes into blades and prints into protective wards. Her Noble Phantasm draws on her famed woodblock style and iconic wave imagery, conjuring a towering tsunami of inked waves that crashes across the battlefield, sweeping away foes. She speaks with a playful, mischievous charm, often teasing allies while delivering decisive blows. Across missions she demonstrates a curious, restless spirit, collecting ideas, pigments and patterns from the eras she visits, always seeking to capture the elusive moment of beauty in chaos.
