Umiotoko (Sea Man)

The creature has the head and upper torso of a humanoid with a broad, reddish, bald scalp and prominent, wide-eyed gaze. Its lower body is covered in red, fan-shaped scales with dark accents, resembling a fish, and a row of sharp, triangular dorsal spines runs along its back. The figure is partially submerged in pale blue, stylized water rendered with repetitive swirling lines. Below the creature, a fragment of a white, mask-like form with blue and pink details is visible in the foreground.

The Umiotoko is a yōkai from Japanese folklore, often appearing in illustrated scrolls (emaki) cataloging strange phenomena and creatures known as bakemono. It represents the Edo-period fascination with natural history, the classification of the unknown, and the inclusion of sea monsters in the broader taxonomy of the supernatural.
