Sanemi x dying reader

3rd Person's POV

"Sanemi-kun~" a (e/c) slowly creeped out of the door. The young man looked over the girl and resumed his sword maintenance

"What do you want?"

"Cold as ever, aren't we?" The girl hummed

"Tch, if you're only here to bother, then get lost" the girl pouted at the man

"Just where did my lil cute Sanemi go?" She sighed

The girl skipped out of the room, knowing that the boy doesn't want anyone near him at the moment. Walking at around their estate's garden, she took a deep breath while reminiscing the things before she reached her current position. A crow landed at her shoulder, making her jump a little

"A mission, a mission!" The crow informed

"Alright, alright... I get it already so will you please not land on me out of nowhere?!" The Crystal Pillar whined. Little did the girl knew, Sanemi was behind the walls, listening to her beautiful voice as he gave a small chuckle at girl's attitude

"Alright, alright~ Shall we do some work~?" (y/n) half heartedly declared and did some warm up before heading out

"That idiot..." he murmured. He looked above the sky and clenched his hands. He and (y/n) had been together ever since they were children. Just as his family met their fate at their own mother's hands, (y/n) parents was around to take care of the children. Unfortunately, they were also caught up in the accident. Only the two brothers and the little girl survived the brutal massacre. Barely getting on with their life in the streets, the three stood by together until Sanemi left the two he loves the most, thinking that being a demon slayer and protecting the two would lead them away the cruel fate of the world.

(Y/n) promised Genya that she will definitely bring his brother back and live a normal life just as they did before. Days became years and before the three of them realized, their bonds was getting blurry. Catching up to Sanemi was really hard for (y/n). She almost gave up as she heard that the boy was declared as one of the Hashiras. But with her resolve, she stood up and did everything she could so she could be beside the man who gave her hope.

To be honest, their current relationship is better than when (y/n) became a Hashira. She was always given a cold shoulder and mostly ignored. He even spats things that could crumble someone's world hoping that the girl would go and live a life out of danger. But (y/n) didn't waver, hoping to fulfill her promise with Genya. As years passed by, the little wish that she and Genya made was slowly but surely starting to diminish. It became more and more impossible for the girl to let go of her job as she foresee a lot of death before her eyes, fueling up the hidden rage she felt ever since her family's incident. And today, she's fighting for the sake of eradicating the demons once and for all

(Y/n) arrived at her destination. Looking around the town was sure fun but the girl knew playing around will cause more trouble for the people near the area. She instantly traced for the demon's whereabouts. A smile suddenly crept out of the the girl's lips and a menacing aura suddenly enveloped the surroundings

"Shall we dance, my little demon?" She said as she instantly disappeared into thin air. The demon was shocked to hear what the girl just said

'She hasn't noticed me yet, has she?!' He nervously asked himself

'Yes... That's impossible, I'm pretty sure no one will be able to detect my—'

As if the demon jinxed himself and slowly noticed his head was flying

"That's my body?..."

"Goodnight, little demon~" he saw a silhouette of a frail yet intimidating girl putting her sword slowly at its hilt
