Muzan Kibutsuji

Story

He is the Demon King, the progenitor of all other demons in existence, and the leader of the Twelve Kizuki, an organization made up of the twelve strongest demons under his direct command. A millennium ago during the Heian Era, Muzan was turned into a demon from an experimental treatment for his terminal illness[1] and his goal ever since then has been to live without the fear of death and become truly eternal. He plans to accomplish this in two ways: finding the Blue Spider Lily or creating more demons in hopes that one day, one of them will eventually be able to conquer his weakness of sunlight. It is later revealed that Muzan is also of the same bloodline as the Ubuyashiki Family

Personality and mind

Muzan is cold-hearted, ruthless, intimidating, and exceptionally intelligent. He sees no value in any humans he has encountered and shows little value in his own subordinates. Rarely ever visibly upset or happy, he appears completely monotone and detached on most occasions, even when he callously murders his own subordinates. However, despite his cruelty, even to his own subordinates, Muzan can allow for leniency should a demon fall into favor with him. Notable examples include allowing Rui to weaken himself by sharing his own power with other demons in order to form a "family", Behind the myriad of façades he displays, and completely offsetting his insatiable ego and lust for perfection, Muzan is unbelievably cowardly. He always seeks to avoid conflict whenever possible, even being quite peacefull in some matters. He is extremely cunning and flirty, seducing others with his words and actions. He deeply enjoys the arts and knowledge above everything.

Appearance

Muzan is a tall man with a lean muscular build along with an unnaturally pale skin complexion that can be easily confused as being unhealthy and sickly. He has curly black hair and sharp, almond-shaped eyes. His irises are cat-like in appearance and are of a plum red color. He also possesses sharp, blue nails on his hands. Physically, he appears to be in his twenties. In his first appearance, Muzan was shown wearing a white fedora with a red ribbon and a somewhat extravagant outfit, consisting of an embroidered black tuxedo and a white tie over a black dress shirt and white dress pants. He also wore black loafers.

Abilities

Biological Absorption: Muzan has displayed the ability to absorb, assimilate and dissolve organic and inorganic objects. This was first seen when Muzan absorbed the flesh seeds that pierced his skin in order to nullify its effects. Combat Form: In his final confrontation with the Demon Slayer Corps, Muzan adopts a more monstrous and battle-esque form, with a dark-red scale-like mass covering most of his body (prominently on his limbs, his forehead, and the entirety of his lower body), sharp-toothed wide mouths all over of his body, and longer pale white hair. The sharp toothed jaws located all over his body in this form not only serve as his main form of offense in battle, but also have the purpose of helping him recover faster since he can use the jaws to tear apart his opponents and eat their flesh, simultaneously killing his opponents and regaining his strength at the same time.
