Rey Demonio Inmortal y su Ángel

The captivating realistic cover of "Immortal Demon King and His Angel" features a close-up of an androgynous man with pale skin and white hair, attired in a rhombus-cut, tight white outfit, is dramatically reaching out with an obsessive expression. Behind him, dark magic imbued with rhombuses crackles with power. The title, "Immortal Demon King and His Angel," is emblazoned in a sharp, crystalline font, positioned above him as if formed from shards of dark energy.
