Generate a photorealistic image (7680x4320) of "Acala Tengu" (Fudou Myouou Tengu), a mighty Tengu with a body as black as night, his wings crafted from obsidian and fire, his eyes burning with an unwavering resolve. He stands on a mountain peak, his beak open in a silent roar, his hands clutching a flaming sword and a staff forged from lightning. He is a protector against evil and a guardian of truth and justice.
