character: katsushika_hokusai_\(fate\), character: abigail_williams_\(fate\), character: mysterious_heroine_x_\(fate\), A medium shot, eye-level scene set inside the traditional indigo dyeing workshop at the Aino Yakata in Tokushima, featuring three girls engaged in an indigo dyeing experience. Katsushika Hokusai, with short purple hair and blue eyes, wears a simple shirt under a deep indigo-blue apron, leaning forward with a look of intense curiosity while a small black octopus floats playfully above her head. Abigail Williams, with very long blonde hair adorned with orange polka-dot bows, also wears a shirt and indigo apron, her face beaming with a joyful, excited expression as she dips fabric into a vat. Mysterious Heroine X, with blonde hair in a ponytail and blue eyes, wears a shirt and indigo apron, focusing with surprising seriousness as her hands carefully manipulate the fabric. The environment is a traditional Japanese workshop with wooden beams, vats of deep blue indigo dye, and hanging dyed cloths. The lighting is natural and soft, filtering through paper screens, with a clean anime illustration style and a palette dominated by various shades of indigo blue and warm wood tones.
