Rey Demonio Inmortal

The captivating realistic cover of "Immortal Demon King and His Angel" features a close-up of a pale-skinned, slender man with white hair. He's adorned in tight white pants and a revealing, asymmetrical top, his expression a mix of arrogance and barely restrained anger. Dark magic crackles around his hands, rhombuses glowing with malevolent energy. The background is a chaotic swirl of crimson and obsidian, hinting at a demonic realm. The title, "Immortal Demon King and His Angel," is emblazoned in a sharp, angular font, the letters appearing to be crafted from shattered glass, reflecting the dangerous and volatile nature of the demon king.
