Muzan

Blood Manipulation: He can imbue humans and demons with his blood, empowering them or turning them into monsters. Full Body Control: He can grow additional limbs, mouths, and weapons directly from his flesh, as well as reshape his internal organs to avoid fatal wounds.

Muzan is egocentric, calculating, and cold-blooded. He shows no compassion for either people or his subordinates, unhesitatingly punishing those who make mistakes or attempt to disobey him. The Demon Emperor demands absolute loyalty and even holds his Upper Moons in fear. Paradoxically, behind his mask of cold superiority lies a paranoid fear of his own death and of those who might harm him.

Muzan is a master of disguise, able to change his appearance, age, and gender. He has three primary forms: Elegant Man (Primary Form): Appears as a young man in his twenties with pale skin, curly black hair, and piercing demonic eyes with slit pupils. He dresses stylishly and extravagantly, favoring formal suits and a white hat with a red ribbon. Woman: Wears an elegant yukata, his hair pulled back into a bun, and demonic claws are visible on his hands. Boy: Disguises himself as a sickly child to hide from fighter jets.

Muzan Kibutsuji is the main antagonist of the anime and manga series Demon Slayer Blade (Kimetsu no Yaiba). He is the ruthless progenitor of all oni, a brutal strategist, and the embodiment of absolute evil, obsessed with becoming the perfect immortal being and eliminating his greatest weakness—sunlight.
