Zenitsu Stories

The Demon Corps had done it-the impossible. The endless war ended with the Demon King's death beneath the piercing rays of the rising sun. Yet victory demanded the ultimate price... none lived to see it. The nightmare was over. But not for one man. A swordsman blessed by lightning rose from the ashes. No longer the trembling coward, he vowed to become the wall that would defy time itself-to shield the ones he loved and strike terror into demons like the wrathful thunder of the heavens. Zenitsu Agatsuma awakens in a world both achingly familiar and impossibly distant. Fate has given him a second chance-or perhaps a cruel jest. Haunted by battles yet to come and faces he could not save, he walks a fragile path where even the smallest change could unravel destiny. And as shadows gather once more, a single question remains: can he rewrite the future, or has fate already chosen his end? ----------------- MAJOR SPOILER FOR THE DEMON SLAYER MANGA!!! READ IT AT YOUR WON RISK! Disclaimer: I do not own Kimetsu No Yaiba or any of the characters from this story except any OCS that I may create in the future.

I'll get to the point; You get Isekaid , and you end up in Demon slayer with your favorite characters and a particular blond- BUT the side effects of getting isekaid turned you into the enemy of all demon slayers. In here, some might attack you, some might be confused by you, and some may ask for your hand in marriage. The thing is... your transformation into a demon has caused your memory to get foggier as the days go by. Will you remember yourself in the end? Your worth? Or will you end up a mindless, uncontrollable demon? ANYWAYS (Update!! I might turn this into a kny x reader, but know that you'll probably end up with Zenitsu. Because that's what the books about). Also, a ⚠️Disclaimer⚠️ the book might contain some things that I hear some people are uncomfortable with, like gore, cussing, something close to smut (?) maybe idk, BUT if you don't care about these things READ AS MUCH AS YOU WANT Just wanted to let you know in case i might cross the line, bc i might write about this in later chapters... Idk we'll see how far you'll want to go with these characters ( Y'all prolly know this already, but I do not own demon slayer nor the fanart!! ) ⚠️ warning!!⚠️ I only update when I want to and when I have the time! So when you decide to read please don't expect too much of me. I'm really busy with real life and I hope you can understand how that is. 🙏❤️✨

For years, not a single demon had been sighted there, and there were no records of anyone disappearing due to demon activity. The Corps believed the village to be free of demons. But what they didn't know was that someone else had been protecting it, a Demon Slayer unknown to the rest of the world.

Y/N Rengoku, brother of Kyojuro and Senjuro Rengoku and son of Shinjuro and Ruka Rengoku, is a powerful demon slayer.

What begins as a professional collaboration between rival crews quickly spirals into viral fame, high-stakes performances, and an unforgiving spotlight. As the line between idol and person blurs, Tanjiro and Zenitsu fall into a rhythm that was never on the schedule, one that could either survive the pressure of fame or burn everything down.

In the world where demons used to run rapid the demon king Muzan Kibusuji was defeated and demons finally came to an end. Tanjiro, Nezuko, and all the others they met during their journey finally were able to go back to a mostly normal life and put their demon slaying past behind them.

They had little choice, knowing it was for the greater good they had to look back as the new Hashira.

"Run Himari ! Take Sumie and make a run for it!" . . It was a demon, no doubt. But the numbers had scared her the most. She knew who that demon could be. Upper moon one. . . . The Tsugikuni brothers, Yoriichi and Michikatsu Tsugikuni were the ones to create the first and second breathing techniques, Sun and Moon breathing. Although Yoriichi's Sun breathing was passed down from one generation to another in the Kamado bloodline as Hinokami Kagura, or "Dance of the Fire God", many believed Moon breathing was never passed down. But what if it was also passed down from one generation to another along with Sun breathing with its original name? In the Taisho era when demons are everywhere, hiding and preying in the dark, what if the last surviving swordswoman from Tsugikuni bloodline comes to the front lines to fight against the demons with two most powerful breathing techniques by her side? {This is a fanfiction of my favourite anime. All characters other than my ocs belong to the original creator of the Demon Slayer manga artist.}
