What if Muzan found out that the Kamado family were the descendants of Yoriichi Tsugikuni, the first breath, and went to destroy them, but ended up not killing Tanjiro and raising him to make him a spy for him? Beware of manga spoilers!! 🚨 ~~~~~~~ This is a personal fanfic, there's a lot of fanfics that are like mine, so don't be surprised if you read something like that. And I DO NOT OWN any of the characters nor the original story. #1 swordfighting 2022/02/01 #1 demonslayercorps 2022/08/02 #1 douma 2022/08/19 #1 blooddemonart 2022/09/25 #5 powers 2022/12/07 #2 demonhunter 2023/02/22

Hai so this is a story where Yoriichis wife had a child after a while she died so but the child was Tanjiro.

Rengoku is sent out on a mission to take down a demon north of the demon slayers corps building. The Master tells Rengoku to take Tanjiro with him, for this demon has a really faint smell. Tanjiro agrees to go on the Journey, but struggles to leave his sister behind, due to the Masters orders. Tanjiro learns more about the Flame Hashira on the Journey, and his feelings of admiration grow into something more.... meanwhile Rengoku focuses more on their mission, But soon, Tanjiro's survival becomes more important to Rengoku than the Mission, and soon, something goes on between them, something that changes their relationship forever. (this may include just a little 18+ and above aka sex. I'll have a warning at the top of the chapter if you wish to skip it, and also this takes place before Mugen Train! Hopefully, this isn't to confusing for you)

What if Tanjiro wasn't a boy, but a girl named Tanko dressed as a boy going by the name Tanjiro to keep her identity secret. Her reason for this is that people always judge her saying that women are weaker than men and are meant to protected. Tanko wants to become a demon slayer to turn her brother Nezuo (yes they both swapped genders) back into a human and prove that women can be stronger than men. Read as an unexpected love story unfolds in all its twists and turns. Will her identity be found out? Read to find out!

Yoriichi had once been the best swordsman. Even as an Omega, he was feared by Demons. But choices led to his leave. What choices might have forced this conclusion? His love for the Demon King, Muzan Kibutsuji. His one and only mate. His destiny. (Cover Drawn by me) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (This is a story following Tanjirou as the child of Yoriichi and Muzan. Will be a long series I do, following through the years of Tanjirou's growth. Drama, fluff, and multiple relationships are guaranteed in this adventure.)

Tanjiro had always done his best on missions, succeeding and pushing onward. But one thing continued to bug him. After his first encounter with Muzan, something in him twisted to force a different emotion. It was confusing to him and left him wondering what it meant. Who knew fate would offer the answers. Once enemies, the two begin to grow inseparable, forcing meetups beyond the eyes of everyone else. They viewed Muzan as a monster, but Tanjiro saw it all. The Demon King was just lonely. Once Enemies, The Two Become Something Forbidden. But There Is Always A Price To Pay.

Tanjiro is unwanted in his own household. Even after failing to save his family his sister Nezuko who survived left him. He becomes a demon slayer just to search for muzan to kill him. When he does find him, how will muzan react? What would this do to the demon slayer corps? Will some more people end up dead or will they turn to the demon's side? It sucks but I just came up with it. Might not update as often. Also cover art is not mine. I don't own Demon slayer. I do own the plot tho. It will follow some of the canon plot but more of my own. I mostly post once a week. Don't ask for the date bc it will not always be right. I also suck at grammar so if you see mistakes then i'm sorry. Other than that enjoy the story and see where it goes with me. Enjoy ~Iris/Nex/Author-chan Started: November 27, 2021 Ended: ??? P.S. It has been chosen that a gay Harem will be going on. There will probably be a bit more of giyuutan tho. I will not write another book until I finish this one but make sure to look forward to some of my future stories! ~Iris/Nex/Author-chan out!

So hello! I decided to do my take on the demon Tanjiro trope! But it may be a little different than what you expect. There's always the classic AU where Tanjiro is turned into a demon instead of Nezuko and she goes on to become a demon slayer. Which is all jazzy and nice, but I wanted to try something else. In this world, Tanjiro will be turned into a demon during his time as a demon slayer. And a harsh reality will come upon his comrades and friends. Along with becoming allies with enemies. I don't think I'll shipping anyone with Tanjiro in this book just because I feel like tying in romance in this story will kinda affect the vibe I imagine for it. But don't worry I have other books planned. Speaking of books, this is my first one, so my writing is (WILL BE) kind of horrible. So I'm sorry in advance. ≡(▔﹏▔)≡ DISCLAIMER: Demon slayer and its characters do NOT belong to me. DISCLAIMER: The lovely artwork does NOT belong to me. It belongs to にこ @haiduki295 on Twitter. Please go support them!!!!! P.S: If someone already came up with a story concept like this first please let me know!! I want to credit them properly!

Muzan was getting strange reports of demons getting killed off in large numbers, he investigated and heard something that horrified him "Sun breathing, first form: waltz" This will be a tanjiro x mitsuri ship and slow updates

In this au tanjiro has been trained by his father tanjuro to use sun breathing. Tanjiro can use sun breathing 12 forms without any backlash, he does not know the 13th form of sun breathing. Another thing he looks a lot like yoriichi so muzan Jackson is going to have lot of heart attack when he will meet him in this au. The story will be quite similar to cannon timeline only that tanjiro is going to be a prodigy like muichiro tokito. Note English is not my mother tongue so there could be grammatical mistakes in the chapter so I apologized.
