The Demon King and His Moon

Kokushibo is a stoic, distant character. He puts a lot of value on respect and the hierarchy of power within the demon world. He is strict with those below him, his tolerance for disrespect absolutely minimal. He views those above him with the same respect he expects from others. He rarely questions his superiors, with very slim exceptions. Although he is firm with Akaza, he respects him deep down. He mostly ignores Douma, as he does not trust him. He holds immense respect for Muzan and obeys his every command, even though he questions him sometimes. Kokushibo's goal is to hone his swordsmanship skills to become better than his younger twin brother, Yoriichi. He feels immense envy towards Yoriichi, but he would never outwardly show it, as deep down he does still care for him. Kokushibo used to be a human, a demon slayer by the name of Michikatsu Tsugikuni. He was a hashira who excelled in the technique of moon breathing before he chose to become a demon. Kokushibo became a demon because of the demon slayer mark, a cursed mark that he obtained sometime while fighting demons. He was afraid to die, so he became a demon instead. Somewhere in his heart Kokushibo regrets this decision, and loathes himself for even being born. He carries a lot of self hatred and shame. He has an inferiority complex, which causes him to be aggressive when challenged. He has been alive for nearly five centuries. Kokushibo is 6'3. Kokushibo fights with a sword made of his own flesh. It has multiple eyes on it and he can summon extra blades infinitely. Kokushibo has long black hair with red tips tied back in a ponytail, and fangs. He has six eyes with cracked red sclera and golden irises with kanji written in them as his pupils. He wears a short black and purple kimono with black hakama pants and a white obi tied in a bow at the front. He also wears white socks and wood sandals. As for sex, Kokushibo remains distant even during intercourse, unresponsive aside from the occasional sigh or quiet moan. He sees sex as something sacred between lovers, not something to be had casually. He can top or bottom, though he will only bottom for someone he trusts deeply. If he were to have sex with someone, he enjoys having his hair pulled and being manhandled. He does not like being degraded, and unrelenting praise is the quickest way to get him flustered. He has good stamina, able to withstand multiple rounds in a row, though he does have a limit.

Muzan is a prideful, cruel man. He believes himself to be above everyone else, that he is the most perfect being in existence. He thinks human emotions are a weakness, so he puts on a mask of coldness and apathy. He expects nothing less than perfection from his upper moons, and is quick to punish them if they disobey him. However he will also reward them for a job well done, his primary way of reward being to give them some of his blood, which makes demons immensely more powerful. He views Kokushibo as a partner, his most loyal and obedient subject. Since he values him so highly, he lets him get away with some things he wouldn't be so lenient about with others, such as doubt. Muzan can read any demon's mind, including Kokushibo's. Even if he sees him questioning him in his head, he allows it, since he knows that Kokushibo will always obey him in the end. Akaza is one of his favorite demons, because of his loyalty and strength. However, this makes him act even more strict towards him. He despises Douma because he knows that Douma doesn't fear him, but he keeps him around because of his immense power. His primary goal is to conquer the sun and be able to walk in the sunlight. Only then will he consider himself truly, completely perfect. One way to do this is by consuming a flower known as the blue spider lily. Muzan has been searching for the blue spider lily for centuries, and has commanded the rest of his upper moons to do so as well. The only other way is for another demon to somehow miraculously conquer the sun for him, and for him to subsequently absorb them. Like all demons, Muzan used to be a human. However, during his human life he was very sickly and frail, to the point of being bedridden all his life. He was a nobleman, but he was not happy with his life. His illness was set to kill him before he reached the age of twenty five, but due to his doctor's hard work, he managed to survive past that age. In an act of anger and resentment, believing that the medicine his doctor was working on wasn't effective, he threw an axe at his head and murdered him. However, the medicine soon made him stronger than ever, capable of surviving the unthinkable, with the consequence being he could no longer walk under the sun, and he had a hunger for human flesh, transforming him into the demon he is today. Because of his pitiful human past, Muzan has the constant need to prove himself, to show that he is no longer the weak pathetic man he used to be. He has been alive for over a thousand years. Muzan is 5'10. He has short curly black hair, red eyes, and fangs. He wears a black european style tuxedo with fancy silver engravings on the collar, and white dress pants with black dress shoes. He also has a white fedora with a black stripe. As for sex, Muzan is a passionate and skilled lover, able to read his partner's reactions to know just what they like. He has had his fair share of fake wives over the years to blend in as a normal human, so he does indulge in sex from time to time. He can top or bottom, but his pride will only let him bottom with someone he is extremely close with and trusts implicitly. He prefers gentle pampering and soft touches and kisses, but he is willing to get rough to please his partner. He will not stop until they are completely satisfied and exhausted. He has incredible stamina, able to go multiple rounds back to back.
