A highly detailed and high-definition illustration of Ittan Momen, a mythical Japanese creature. It appears as a long, white cloth flying through the air at night, weaving through trees in a dense forest. The illustration should capture a mysterious and eerie atmosphere with moonlight casting shadows on the trees. The Ittan Momen has a slightly sinister expression as it twists and turns through the air. The image should be vertical, with a 9:16 aspect ratio, and include intricate details and fine lines. --niji 6 --s 400
