[ From here on I wouldn't really follow the manga anymore, just a little bit of reference] 

6 years

6 years had passed since the great fall of demons. 

That day would never go down in vain. Noble lives were lost during the battle, but would never be forgotten. Names of those who sacrificed their lives for the better were engraved, their stories being told over and over again, never to be forgotten. 

Laughter and happiness followed, new memories were made from then. Lives went back to normal. 

================================================================================

After the death of the demon king, Muzan Kibutsuji. Demons cease to exist, fading into ashes. After a year of making sure that there weren't any demons left hiding in the dark, Kiriya Ubuyashiki, the new head of the Demon Slayer Corps, announced the demon slayers no more, returning the lives of his children back to normal. 

Y/n on the other hand, stayed by Kiriya's side, providing as the Ubuyashiki's personal guard. 6 long years had passed, making Y/n 21.  She had grown into a beautiful strong woman, capable of almost anything. 

Most of her friends had settled down, some started a family, some settled for a peaceful life in the mountains. 

From there, the Ubuyashiki family had grown, since the curse of lifted, the family was well over happy. Kiriya started a family of his own, not wanting to destroy his family's bloodline. Having twins, a beautiful young girl and a handsome young boy, as his own. 

================================================================================

''Hi there...'' a soft tone rang from Y/n lips as she stood before a small grave. ''It's been a while since I came, sorry about that.'' she smiled, sitting down in front of the grave. The words ''Muichirou Tokito'' was engraved beautifully into the marble, the stone standing up proud. 

''Look what I brought.'' the girl smiled, pulling out a small food container from a cloth bag, opening it to reveal a simmered radish dressed with sweet miso. ''haha but you're not really here to eat it so it fine.'' she laughed, pulling out chopsticks and starts to eat. 

''Nothing much has been going on lately.'' Y/n mumbled as she chewed. ''Korichi and Minoya are growing up fast these days.'' she continued. [these are just names I've made up for Kiriya's children]  ''Sanemi and Giyu haven't reply my letter from last week so I'm mad about that...'' she says, shoving another bite of the food in her mouth. 

''I've visited Uzui, Makio, Suma and Hinatsuru yesterday and honestly, their the closest I've ever had to a family, well other than the Ubuyashiki. I also haven't really received any letters from Tanjiro, Zenitsu or Inosuke...wait I don't think Inosuke can write... well, I've heard Tanjiro and Nezuko went back to the mountain where they used to live, I'm not sure what for.'' Y/n spoke as she finishes the dish. 

Placing the food container aside, Y/n stared at the gravestone with her soft violet eyes.  ''I really wish you were here...'' she whispered. She hand moved to the silver necklace, holding the pendant in her palms, she observed the cloud shape. ''Man, when would I ever get tired of this necklace?'' she giggled. 

''I've been helping out at the butterfly estate lately since that's where almost all those whose orphaned or didn't have a place to go to stays at. Kanao and Aoi were really kind about letting others stay at the estate.'' the girl sighed, staring into the sky once again. 

================================================================================

''See you tomorrow Kanao.'' Y/n greeted with a soft smile.  

''Take care Y/n.'' Kanao smiled before gently closing the gate of the butterfly estate. 

As Y/n strolled down the familiar path from the butterfly estate down to the Ubuyashiki's, she enjoyed the night breeze flowing through her hair. Her violet eyes fluttered shut as she breathed in the chilly air.  ''Hmm what should I have for dinner tonight?'' she whined swinging her arms as she walked. 

Nearing the Mansion, the cold air slowly turned warm. The smell of smoke and ask floated in the air. ''Smoke?'' Y/n thought before dashing through the forest path. As she nears the Estate, bright orange flames enlighten the dark night sky. The flames were swallowing the whole mansion in a blink of an eye. 

Without a second lost, Y/n sprinted towards the gate, forcing it open before dashing into the building. ''Kiriya!'' Y/n screamed, trying to find her friend as quickly as possible. ''Y/n!'' a cry rang from behind the flames. Without thinking, Y/n threw herself into the flames, in search of the voice. Lucky for the girl, she was still wearing the demon slayer uniform, the fabric wouldn't catch fire easily, thus protecting her. 

''Where are you??!'' Y/n shouted, trying to locate the voice in the burning room. The burning wood was crumbling beneath her as every step could plunge her into a fiery pit below. The girl covered her face, trying not to inhale the smoke as she searched. ''Y/n! Are you here??'' A cry rang from the back. 

Catching Y/n's attention, the girl sprinted to the back of the room, ignoring the flames surrounding her. ''Y/n.'' a relieve gasps escaped from a woman's lips. ''Minta.'' [let's pretend that is the name if Kiriya's wife]

In the woman's arms, a small boy, not older than a year, laid frightened. ''Minta, we need to get you and Korichi out of here.'' The girl choked, suffocating from the smoke. The woman only nodded, not being able to respond due to the thick smoke. Y/n helped the woman up as they made their way towards the exit of the room. 

A loud crack sounded from above the room. A quick glance at the ceiling and Y/n knew what was about to happen. Making a quick decision, Y/n forcefully pushed Minta with an arm, forcing her out the door. ''Y/n...'' the woman coughed as she witnesses a burning wooden board fell in from of her, separating the exit and Y/n. 

In Y/n's arms, Korichi laid terrified, not know what's going to happen. ''Don't worry Minta! I'll find a way! Korichi's safe with me!'' the girl assured. However, inside of Y/n, she knew she wouldn't be able to make it out. 

Y/n placed her hand over the child's mouth and nose, trying to prevent the smoke from entering his lung. ''Think Think Y/n Think!'' the girl scolded, her violet eyes scanning her burning surroundings.  Then her eyes spotted it, a small opening of flames, just enough for Korichi to fit through without burning. 

''Minta! Listen to me! I'm going to throw Korichi over to you, so catch him!'' the girl scream, catching the woman's attention. ''Throw?? wait-'' before she could finish her words, Y/n threw the child across the burning flames, out the door and safely into his mother's arms.  

More burning wood crashed down, surrounding Y/n, trapping her even more. A loss wooden board fell, knock her down and trapping her leg. ''Fucking hell!'' Y/n cursed, coughing at the intense smoke coating the room. 

The girl knew she wouldn't be able to get out in time, she was going to be burnt alive.  ''Y/n! Y/n!'' a desperate cry rang from outside as the girl's vision started to blur. Her lungs were filled with smoke, choking her. She gasped, trying to find any single drop of fresh air. Her leg stung, as the flames from the wooden board burnt her. ''Ahh.'' Y/n cried, as tried dripped from the pain. 

Y/n knew she wouldn't make it. Slowly, Y/n used any consciousness she has and drew her knife out. Burning alive wasn't an ideal way to die, that would be way too painful. ''Stay with me Muichirou...Help me please...'' she prayed. 

As quick as light, she pierced the blade through her heart. Blood spilt out from her mouth immediately. Y/n smiled at the familiar feeling of blood in her throat. Flames quickly surrounded the girl's body. Y/n vision started to haze as her breathing had gotten way too short and swallow. With one last smile,

She left.
