"Do you promise...?" "I promise..." Y/n, less than a quater demon, and more human then not, has been alone most of his entire life. Besides the Kamados' and his sister, he's never really been close to anyone. But life isn't fair, and the smell of blood tends to grow every second. Killed, murdered...no...Slaughtered, that's what the Kamados' were. But Tanjiro, Nezuko, and Y/n are determined to turn Nezuko back and hunt down the killer. For that to happen, Y/n must embrace his demon side and harness the power of the Tessaiga. But can he stay in control? Or will he lose himself to his demonic bloodline? (Disclaimer: If you couldn't tell, this is a cross over of both franchises. Meaning stuff like Demon Energy and stuff from Inuyasha will be in this story)

Y/N never expected this. She never thought she'd be fighting demons. No one thought she'd know the sun breather. Now here she is, sitting in the dark. Sitting alone, wishing to fix what was broken. I can still gaze at the stars I never expected this to be so... So... ... Real [This will contain spoilers for the kny series for all you anime only.]

Join Y/n in becoming a hero with his honestly op abilities of being a demon along with some new power, what is the new power? guess you'll have to read to find out. BTW this is my first fanfic so i appreciate any support I do not own kny, mha or the cover art nor do i own any characters from either universe. please enjoy and thankyou for reading.

In a word infested by immortal beings known as Demons. People coward in fear and lived under their threat for decades, not knowing what or who they are as they had seemingly just suddenly appeared. But few brave warriors know as the Demon Slayers picked up their weapons and trained in the art of the Katana to fight back and kill these creatures, despite the severe disadvantage they were at. Their limbs don't grow back, their wounds take longer to heal, and will die an easy death to such powerful creatures, yet to even out the playing field, they have created what's know as breathing styles. Everyone has their reasons to joining the core and training with a style, some might be for money, others might be for unfortunate circumstances that set them down this path, but one things for sure, they all fight to protect humanity. Now a young man has grown and decided to become a slayer for reasons only know by few, what such reason? Why don't you find out for both of us?

You're new at the Demon Slayers Corp. Sought after by the Master for your recognition of defeating over 100 demons single handedly and w/o the help or even knowledge of the Corp. You're known for your ruthless tactics & unwavering hatred for demons. Orphaned at 14, Doma, an upper rank demon, decided to take you in, rather than kill you, because of his obsession with your beauty and intellect. He had all intention of turning you once you reached a more suitable age. Needless to say, that was a nightmare you will never fully heal from. Some of the Hashira are weary of letting someone so shady, & unpredictable just join so quickly... then again you are the only person to ever master multi-breathing techniques period, let alone w/o a Sensei. Kagaya has asked you to join his beloved Hashira and become a demon slayer to stop all the endless suffering. He even assigns you Tsugoku, Tanjiro Kamado; being that besides you, Tanjiro is the only other person who can use two breathing techniques. You know you can help him perfect his sun breathing. And you are a tough Sensai, because you expect the most from Tanjiro. Two Hashira among them all have caught your attention and vice versa. Afterall you've suffered through, you didn't ever expect to find love, much less, to love two people at the same time. You try to push them both away, but they just won't let it go & they've made it VERY clear neither of them is going share you. (NOTE: QUITE A FEW EVENTS HAVE BEEN ALTERED. SPOILERS INCLUDED)

Y/N. He is a boy whose life was changed when demons attacked. Seeing the death of his family filled him with sadness. And Rage. That day he decided to become a demon's worst nightmare. They are wicked. They are terrible. They are heartless. But Y/N? He will be worse. He will make them regret their existence. He will not stop until every demon in the world is extinct. Until they are all gone. He will rip and tear until it is done.

He was known to be a hot-blooded individual. Showing little to no concern about anything or anybody. Except towards the swords he creates with his burning passion. Many disliked him, finding him to be very difficult to approach. Given how hot-headed he was, yet the passion he had for swords made him stand out from most of the swordsmiths who made swords for the sake of it. He didn't need anything else. Nor did he need love. He just wanted to create swords after swords. Only to realize he had other feelings, for a particular Hashira. Then many started to question then, why would someone like her fall in love with someone as hot-tempered as him? And how?

An alternate take of the canon story where, Tanjiro has learned Sun Breathing, the Kamado family lives, Nezuko becomes a Demon Slayer, Zenitsu masters Thunder Breathing, and isn't scared of everything. None of the Hashira die, some of the battles are changed based off of my imagination. Just keep an open mind about this story as I try and write this. There could be possible lemons. I do not own any of Demon Slayer
