A nightmarish and menacing portrayal inspired by the eerie presence of an evil being rooted in Japanese Oni culture, showcasing a hyperrealistic and intricately detailed portrait. The image is rendered in vibrant 8k resolution, capturing a dramatic mid shot with a 2/3 face angle highlighted by side lighting, set against a vivid and colorful background. The character exhibits an unsettling, grotesque appearance with mismatched eyes, a crooked expression, and an unnerving, detailed composition. This artistic concept explores deformities and mutations, presenting an unsettling and distorted visage with poorly drawn hands and feet, alongside disfigured, out-of-proportion anatomy. The visage is intentionally exaggerated, evoking discomfort and fascination, with peculiar body positioning and strange angles contributing to the overall eerie aesthetic. Despite imperfections, the portrait remains compelling in its haunting richness and nightmarish allure.
