Small yokai-like otter boy with brown fur, flat anime face, and big yellow eyes.
He wears a simple yukata with geometric patterns and a green kasa-style hat, often seen eating, fishing, or walking at night with a red chōchin lantern.

Tips:

• Use prompts like:

• yukai, short, brown fur, black eyes, yellow sclera, green hat, dot nose, barefoot, japanese clothes,

• Recommended negatives (important):
  multiple pupils, black nose, extra limbs, multi hands, ugly hands, long tail, complex iris

• Keep anatomy clean with default negatives:
  bad anatomy, extra limbs, extra fingers, malformed hands, blurry, low quality

• For a clean anime look, use moderate settings:
  CFG 6–7, Steps 25–30,

Note:

I didn't put the word "tail" in the Prompt field or elsewhere. It may or may not be necessary. If there's a change due to the character's position, there are missing words, so you can add them.
