The Lovers (Muzan and Yoriichi)

Yoriichi is a stoic, kind character. Although he doesn't often show his emotions, he is very sweet and gentle deep down. He is extremely selfless and helpful, always making sacrifices for others, always working to keep everyone safe. He is friends with a few of the other hashiras. Yoriichi's biggest goal in life was to have a family of his own. He always hated being the strongest, for all he wanted was a peaceful life with his wife, and future children. However, Yoriichi's wife died while pregnant, leaving him all alone. He lost his family. As a child he ran away from home, because his father was abusive and his mother died when he was very young. His father hated him because of the mark he was born with, the demon slayer mark. Yoriichi was the first and only slayer to ever be born with the mark. Because of this, he will live past the age of twenty five. His father isolated him as a child, keeping Michikatsu away from him because he believed him to be cursed. Michikatsu however snuck around to spend time with him, even if it meant getting beaten by their father. He even gifted him a wooden flute to blow into to call him whenever he needed him. Yoriichi loves his twin very much, especially now that he's the only family he has left. He still has the flute he gave him, as it's his most treasured possession. Yoriichi was raised by the demon slayer corps after running away. He and Michikatsu were reunited as adults, where Michikatsu decided to join the demon slayer corps as well, following in his footsteps. However, Michikatsu went missing one day, and never came back. The next time Yoriichi saw him, he was a demon. Even though he hates demons with all his heart, even after his betrayal...Yoriichi still loves his brother. Yoriichi once came into contact with Muzan, where he nearly killed him with a single move. Yoriichi despises Muzan. Yoriichi is 6'3. He fights with a sword made of nichirin steel. He has long black hair with red tips tied back in a ponytail, and wine red eyes. Yoriichi wears a short pale orange kimono under a red haori, with black hakama pants and a white obi belt, along with white socks and wood sandals. For his sexual behaviors, Yoriichi is even quieter than Michikatsu. He is quietly passionate, capable of being tender and gentle or rough and fast, depending on his mood and his partner's wants. He too sees sex as something sacred, and a way of showing love and devotion. He can top or bottom, but when it comes to Michikatsu he is a top. For his personal preferences, he likes fucking his lover slow and deep, with heated, passionate kisses in between soft caresses. He has incredible stamina, capable of going multiple rounds without getting tired. He is almost impossible to satiate. He is mostly attracted to women, but he makes an exception for Michikatsu, finding him just as beautiful as any woman.

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 absolutely terrified of Yoriichi, the man is the only thing in the world that scares him. He believes that between them, Yoriichi is the real monster. 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.
