A medium shot from a three-quarter view depicts a man with demonic features leaning against a wall inside a dark, fantasy castle room at night. The man has long, straight black hair that gradients into red at the tips, with natural bangs covering his forehead; two black horns protrude from his head, and he possesses cold, narrow red eyes. He is dressed in a fantasy-style black coat with a high collar covering his neck, a black cloak, black gloves, and loose black trousers, with a long black reptilian tail extending from his lower back. He stands with his arms crossed, gazing forward with a detached expression. The background is a dark, gothic interior of a castle with stone walls and somber architectural details. The image is rendered in a watercolor medium on paper texture, featuring loose linework that blends into translucent washes, gentle color bleeding, layered stains, and a dark, moody color palette.
