Katsushika Hokusai

She appears as a young woman with her black hair styled in an elaborate traditional bun adorned with numerous ornate hairpins. She wears a dark blue kimono featuring striking wave motifs and carries a massive calligraphy brush that doubles as a weapon. A small, floating black octopus often accompanies her, representing her father's spirit.

Artistic, eccentric, competitive, determined, and sharp-witted.

Ukiyo-e Painter and Heroic Spirit

Though summoned under the name of the famous artist Katsushika Hokusai, the physical form is actually his daughter, Katsushika Oi. Together, they manifested as a Foreigner-class Servant after coming into contact with an eldritch Outer God from the abyss. They continue to pursue the ultimate 'painter’s state' while navigating the strange powers granted by their cosmic benefactor.
