A medium shot from a low angle featuring a phantom mist demon, a creature composed of swirling black smoke-like essence, centered in the frame. The demon possesses large curved horns and an indistinct, featureless face, with sharp, exposed fangs protruding from various parts of its ethereal body. It wears ornate white armor on both arms, intricately decorated with colorful stained-glass patterns, and a white loincloth paired with a red apron around its waist featuring a prominent emblem. The demon grips a massive greatsword with a distinctively wavy blade in one hand, while large wings made of black mist extend from its back. The environment is a void of swirling shadows and grey mist, emphasizing the creature's imposing presence. The lighting is dramatic, with a cold glow reflecting off the white armor and stained glass, creating a high-contrast, mysterious, and menacing anime illustration with a dark, supernatural atmosphere.
