[Demon Slayer] How Did I Become Kiyuki When I Was Dressed as Kibutsuji?

[Companion to the Naruto Next Door article. ] Once he traveled through time, Utsu Kokonoemitsu became a person from the Heian Era. However, this place is different from his previous life. Here he has parents who love him, a prominent surname, and a frail brother, Fujiwara Tsukihiko, who doesn't like him very much. Although his brother doesn't like him, he really likes his brother. Because on the first day he traveled through time, what he saw when he opened his eyes was this child with black curly hair and crimson eyes, sleeping soundly next to him. However, the elder brother who entered the gate of hell when he was born, the family who has close ties with the priest clan, the doctor who came to the Fujiwara family with a prescription for the blue Higan flower... More and more clues made him seem to understand that the black-haired and red-eyed brother beside him, who looked very familiar, was the one he had watched in the drama "Demon Slayer: Kimetsu no Yaiba". But it doesn't matter, I just have to bear these sins for my brother. Fujiwara Kunoemitsu, no, Kibutsuji Konoemitsu thought so, and followed in his brother's footsteps. Note: ① There is no CP for the two protagonists, the elder brother Onibatsuji Muzan and the younger brother Onibatsuji Kunou Hikari. It will involve the description of the CPs of Kurou, Koro, and Snake. ② A child's body will affect Kokonou Hikari's spirit. The aristocratic education he experienced in the Heian period after time travel will change some of his character and outlook. On Demon Slayer's side, he is a villain who completely revolves around Mukai. When his brother is not involved, he is considered a normal person. In the Naruto sister chapter, he is a pure good person. ②The writing is not good, I am OOC, please don't troll me if you are posting for love, please update as you like. ③The plot of the original work may be greatly changed. The ghost side wins but just ignores the Demon Slayer Squad and goes abroad if. I really can't think of how the ghost side will lose without losing their wits. There may be a series of extras. ④The author likes both the Demon Slayers and the demons, and he is an iron-blooded warrior/Muzan/Tanjiro/Enichichu, so he will try his best to write according to the logical and reasonable development. ⑤The protagonist Long Aotian is set to be a genius in swordsmanship, but in the Demon Slayer world view, he can only stop his opponent for a while and then escape. ⑥ As a time traveler, Kokonoe Hikaru will make jokes in his heart, but he has only watched the Demon Slayer drama and stopped at the Yoshihara chapter, so he does not know the whereabouts of the blue Higanbana. ⑦The private Utanayashiki family used to have a surname of Heian Tai and Fujiwara, and the Muzan human name was Tsukihiko. The Fujiwara branch where the Muzan became a ghost queen was changed to Utanayashiki by the owner to bear all the curses. The protagonist is the ultimate Muzan, and everything is based on Muzan's will as the highest order. Secondly, he will take good care of Yudake, who was picked up by the Black Death Mou, because he thinks he is cute like a cat. ————After going to work, I have no energy to write anymore and I have retreated from ghosts. There is a high probability that I will not be able to write this book. The fragments I have written before are placed under the copy. Thank you to everyone who has collected this book! ———— Made on 2024.9.15 "... My whole body smells like sweat. What the hell did you do?" Fujiwara Tsukihiko frowned, but before he could finish the rest of the words he was about to say, he kept coughing. It wasn't until Fujiwara Kunou Hikaru lifted up the corner of his clothes with a trace of panic and wiped his hands randomly, then took him into his arms and patted his back gently that he gradually calmed down. Yueyan smelled the clean soapy smell on his brother's clothes, and the smell of sweat mixed with it made him unbearable. He reluctantly raised his hands, covered his mouth and nose with his sleeves, took a few breaths, and ordered Jiuchongguang with an arrogant look: "Let me go, don't get your sweat on my clothes." His complexion was very bad, with overly pale skin paired with bright red eyes, a long illness that resulted in purple lips, and sharp fangs that were vaguely covered by the lips. These features, coupled with his fierce look hidden in the dark, almost made the woman standing on the side unable to hold the tray. Her body was trembling slightly, and her toes even tilted towards the door uncontrollably. She didn't know which one was more terrifying, the legendary evil ghost or Master Yueyan, who was lying in bed not long after his death but was still in charge of the life and death of these servants. But she knew that Master Yueyan would lose his temper every time he coughed violently like this. Only Master Kuzomitsu, his biological brother, could survive. Fujiwara Kunoe glanced at the maid without revealing any trace, and first waved her hand to signal her to go out. After the other party escaped with great joy, he took out the medicine prepared by the doctor from the food box placed behind him, put one hand on his brother's back, and carefully delivered the medicine to the other party. "I'm practicing swordsmanship." As Yueyan sipped the medicine, he heard his healthy brother's reply. His face was distorted for a moment, but in the end he didn't say anything. He just drank the soup faster with humiliation, and his fingers buried in the quilt almost penetrated the palm of his hand. Why, why? Fujiwara Tsukihiko was going crazy inside, and jealousy made him ignore the smell on the tip of his nose. He was on the verge of death since he was born, and he is still barely surviving. Although his parents have been supporting him, he knows that his family and even his servants are taking care of him because he seems to have only a few years left, and he will not be in trouble for a few years. And his younger brother, this healthy and intelligent child who was eagerly given birth to by his parents just over a year after he was born, is their favorite heir. He who can only stay in the dark, and his younger brother who can bathe in the sun; he who can only drink bitter medicine and white porridge, and whose stomach is so weak that he cannot even taste pickles, and his younger brother who can taste delicious food and wine at will; he who is named the moon, and his younger brother who is given the name of Amaterasu of Takamagahara; he who has blood-red eyes, and his younger brother who has clear eyes; he who is born with curly hair, and his younger brother who has straight hair like his parents... Now there are other things that he can't match? He, who can only stay indoors and in bed, and his younger brother, who can run freely and practice swordsmanship. The endless jealousy almost made Tsukihiko have murderous intention in his heart. However, when he was about to be buried deeply by those negative emotions, Fujiwara Kunoemitsu spoke again. "Brother." Fujiwara Tsukihiko watched helplessly as Kokonoe put down the medicine bowl, gently put him back on the bed, and then held his hand with both hands. The warm feeling made him seem to feel the temperature of sunlight. "I will be your knife, your sword." Fujiwara Kunoemitsu swore so. He observed his brother's unpredictable expression and hesitated for a moment before deciding to speak out all that was in his heart. After all, he and Tsukihiko are not the twins who succeeded the country in the future. He will respect his brother more than Enichi the country will, until he is taken into Izanami's arms. "I know, brother has always disliked me because of my healthy body." A look of sadness flashed across Fujiwara Kunou's smooth face. He opened his eyes, which were rarely opened after Tsukihiko once criticized the color when he lost his temper. Two pairs of crimson eyes of similar colors met each other: "Then, brother, please treat me as a part of you, your flesh and blood... I am learning swordsmanship just to protect you, Tsukihiko." He called his brother by his name rather disrespectfully, and then continued his words in the silence when the other party became more and more jealous and even thought that he was showing off: "I will make you the head of the family." Fujiwara Kunouguang said decisively: "And me, you can use me however you want, even if you make me a human slayer..." Fujiwara Tsukihiko showed a stunned expression in front of him. He couldn't wait to interrupt his brother's words, his bloody eyes were full of disbelief: "Are you... Saying it true? Xiao... Hikaru." His tone was difficult, as if he didn't want to say the name that would hurt him just by saying it. Even if he was jealous, even if he had the intention to kill, he never thought of letting his brother become a human killer - the most useful dog for nobles to eliminate dissidents. Yue Yan looked at Jiucheng Guang who once again focused his red eyes into thick eyelashes, with a rather complicated mood. He struggled to hold himself up and put his hand on his brother's cheek: "... I want to live." "Well, I know, brother wants to live." Fujiwara Kunouguang's face was calm. He clenched his fists and placed them on his knees. "My father asked the royal family and our family to find the best medical officer. The medical officer said that he would try his best to protect your life. The medicine you drank today is that medical officer's new medicine." Then, Kunouguang leaned forward slightly and spoke in a breathy voice to Tsukihiko Fujiwara, who was shaking after being held up for only a few minutes: "If this cannot cure your disease, I will ask the priest... To give you half of my lifespan." Fujiwara Tsukihiko was like a drowning traveler grasping at straws. He stared closely at Fujiwara Kunouhiko, who had a calm face and was still smiling. His chest kept rising and falling: "Is what you said true...?" Fujiwara Kunouguang didn't speak, he just raised his arm and let the sleeves slide off, revealing his smooth forearms. A trace of dissatisfaction flashed in Yueyan's eyes, but then turned to ecstasy. It was the mark that the priest clan needed to perform secret arts. His younger brother did not lie to him. He sincerely wanted to share his life with him - only those who are willing to share their lifespan with others can be branded with this wisteria mark, and only those with this mark can share their lifespan with others. Fujiwara…Tsukihiko… Fujiwara Tsukihiko stared contentedly at his own name surrounded by wisteria flowers on his brother's arm. He felt so comfortable as never before that he almost laughed. "Then, let me try the new medical officer's medicine again. Jiuchong Guang." He calmed down his breathing and regained his former arrogant look as he ordered his brother, but now his tone lacked a lot of the anxiety and frenzy. It seemed that he was given enough confidence by Jiuchong Guang's actions. "Yes." Fujiwara Kunou Hikaru cast a soft gaze from his eyes that were slightly opened. He put the medicine bowl back into the food box, took out a bowl of white porridge, and patiently fed Yueyan all of it, wiped his lips properly, tucked in the quilt, and then said goodbye to his brother in a low voice: "Then I will leave first. I hope you have a good rest, brother." He walked out of the room facing the light, and this time what clung to his back was no longer the resentment of his brother behind him, but the eyes full of hope. Finally... I can do something for my brother. Fujiwara Kunouguang looked at the mark on his forearm with satisfaction and chuckled in an almost inaudible voice. He put down his sleeves and gently told the maid who blushed at him, who looked very similar to his brother but looked more heroic, to take good care of his brother. He raised his eyebrows with satisfaction when he saw the other party pinching his sleeves and hastily agreeing, and then he carried the food box and headed to the front yard. After saying goodbye to his brother, he still had more things to do. Intent: An explosion of attributes of the cruelty-free chef
