🫐 Do You Remember? | Y/N x Sanemi 😡

(Demon AU, with Female Y/N)

An unmarked grave stood among other slabs of stones, an unknown spirit in the graveyard of honored souls. Y/N hovered above her grave, dully gazing up at the moon. The wind howled, but their stance never wavered. She would keep waiting, no matter how long it'd take. Footsteps began to echo, and she knew he was here. A demon with coarse, long white hair and boney white skin, with dark eyes and a shredded uniform, had arrived. He clutched his head, wincing as a migraine began to strike. Y/N slowly hovered to him. She stretched out a hand, laying it atop of Sanemi. Finally, he had come. Y/N could only hope she was strong enough to help him.

. . .

Sanemi didn't know why he kept coming back here. In the middle of the night, always at a specific time, a sweet voice would lead him back here. Usually, he would break free of the trance, and leave. But this time, he couldn't help but come, to see why he kept being haunted by a voice to return to a graveyard. Maybe, visiting here would stop the voice. His master was already angered by it, for a reason Sanemi might never know.

"Tch. This place looks old and ugly." He scoffed, eyeing the rusty metal gates. He took a few more steps, and was suddenly overcome with a vision.

. . .

"Sanemi-San, wait up!" A sweet voice called out. Sanemi watched as a girl with a blurred out face came running to him. For some reason, he embraced her, holding her tightly. Sanemi could smell the scent of roses from the lady.

"I missed you so much! I was scared you had gotten hurt or something when you didn't reply to my letters!" The lady exclaimed, slapping his arm. "Ow!" He heard himself shout. "I was too busy!" His loud, rough voice yelled. The lady only glared at him. "Alright alright, I'm sorry, idiot." He muttered, crossing his arms.

The lady's face cleared enough that Sanemi could view her smile, and warmth flooded his insides at the sight of it. The girl reached out for another hug, and suddenly, everything turned dark and cold.

. . .

Sanemi awoke on the dirt floor, gravestones surrounding him. He let out a soft gasp as he pushed himself up. He turned his gaze backwards, and saw the same rusty, ugly gate he had chastised earlier. "How the hell did I get in?" He thought, as his head began to pound with the pain of a migraine. "Sanemi, leave the graveyard, now." The booming, unmistakeable voice of Muzan-Sama echoed in his head. He froze, immediately bowing. "Of course, Master." He stated aloud. He stood up, and used his strength to jump over the graveyard at an incredible height. He couldn't help but spare a glance behind him. A girl, with blueish hue, stared at him, tears running down her face. Although, the girl only watched him, sullen. Sanemi ripped his gaze from her, ignoring the anguish coursing through him when he did so.

. . .

"Sanemi. Do you know why I have called only you for a meeting?" His masters intimidating voice rang out, glaring at him from above. Sanemi kept his kneeling position, while fear and anticipation filled his body. He didn't dare think or say anything. "It is because you, an Uppermoon, is being overcome with silly little voices. How useless and pathetic you are." He seethed, his hands forming fists. Sanemi flinched. "Do not let another thing like this happen again, Uppermoon 2." He stated, his eyes narrowing with disgust. The sound of the biwa filled the air, and Sanemi was now kneeling in the forest. Now, anger consumed him, but directed to the voice and that girl with the blurry face. If they weren't in the way, Muzan-Sama wouldn't be as disappointed and angry at him, and he wouldn't be scolded for this as if he were a child doing stupid things.

"Sanemi..." the voice whispered again, but sounding much farther away. Sanemi turned around faster than the speed of light, but still couldn't see anyone. "I'm going to go mad because of a stupid voice." He thought, as he began to walk in search of his next meal.

. . .

Sanemi wound up right back at the graveyard the next night. He knew he shouldn't be doing this. But he felt as if he had to. He felt solemn when he didn't, and he was getting tired of it. "Alright, stupid voice. What the hell do you want from me?" Sanemi yelled at the ugly gates. The only sound in the air was the wind howling. He sighed, staring at the ground. 

Suddenly, the crunch of leaves reached his ears. It was footsteps. He turned around, and saw the girl with the blueish hue. Her face was blurred out like in his memory the other night. "Who... are you?" He tried to say, but the words were stuck in his mind. 

"Sanemi-San. It's been a while." The girl said, with a soft smile. "Who the fuck are you?" He finally said, with a lot more malice and anger in his voice than the girl's. "Sanemi, I need you to listen carefully." Was her reply, her face turning hard and serious. "You need to remember." Sanemi looked at her dubiously. "How am I supposed to remember when I don't have any memory?" 

Immediately, a boy with black hair and blue tips, with dull blue eyes, entered in his mind. He appeared to be a young child or teen, and wielding a sword. "Who is he?" He thought, staggering back. "Tokito Muichiro." A bored voice rang out, and suddenly, Sanemi was somewhere else. He was in the sun, with Swordsmiths, and a young boy with flaming red hair was on the ground, tied up. The dull-eyed boy spoke his name, and instantly Sanemi knew. He was a hashira. And somehow, he knew him. 

A sharp burst of pain exploded in his head, and Sanemi winced. He was brought back to the graveyard, with the girl appearing stricken. "Sanemi..." "Sanemi, stop fooling around." his master interrupted, his voice dripping with venom. He clutched his head, which was throbbing in pain. It hurt so bad. "Shut up, everyone!" he yelled, as the headache worsened. 

Suddenly, he saw a pink and green haired slayer, then a slayer with heterochromia, eating lunch with him. His breaths became louder, as he began to tremble. It was too much. So many people, so many swordsmiths, and he slowly began to remember them. A boy, his brother. A blinded man, his master. Every single memory raced in his head, along with Muzan scolding him. 

He vaguely registered something holding him until he felt himself lowered to the ground. He turned to see the girl, with more of her face clearer to his vision. Another memory flashed through his mind, though it was more peaceful and calm. 

The girl, with his head on her lap, muttering soft, sweet words as she caressed his face. He could see blurry trees in the background, the moon dotting the sky along with the stars. He couldn't help but feel his muscles decompress, all the tension beginning to leave his body. Everything was silent, the only sound in the air was the wind whistling in his ear and the girl occasionally saying soft words he couldn't hear. 

"Do you remember?" she suddenly said, much louder. Sanemi paused, the words slowly registering in his mind. "I think I remember loving you." he spoke, a soft smile gracing his lips. He remembered. His friends, his family, his lover. A reddish color sprouted on the girl's face, as she let out a flustered giggle. 

"But... I don't remember what happened to me." he stated, his smile dropping. He couldn't remember the most recent part yet, the one that could explain how he had gotten here. The girl sighed, her face turning sullen. "It wasn't your fault, you need to know that." was all she responded with. Sanemi gave her a puzzling look. "What do you mean by that?" he asked, tensing up again. What could he have done? 

"Sanemi." was all he heard before everything became dizzy and dark again. He felt his eyes begin to close, as the migraine started again. The last thing he heard was someone yelling his name, before everything turned black.
