A medium shot, eye-level anime illustration portrays a tall, 189cm male Oni standing centrally within a dense, dark forest. The man has long black hair tied into a single, thick braid that reaches down to his waist, and a single flesh-colored horn protruding from the left side of his forehead. His eyes are closed in a slender, curved arc (itome), hiding his pupils, while he wears a traditional red kimono that contrasts sharply with the environment. He stands calmly with his hands tucked into his wide sleeves, his posture poised and steady. The background is a gloomy, ancient forest filled with towering, twisted trees, thick moss, and a heavy mist clinging to the forest floor. The atmosphere is mysterious and serene, with dim, filtered light piercing through the canopy, a muted cool-toned color palette for the environment, and soft shadows that emphasize the vibrant red of his attire.
