The Eternal Paradise Arc (Demon Slayer) by CartoonFuel
12 parts Complete Mature
Sometime after defeating Upper Moons Gyokko and Hantengu, Tanjiro Kamado awakens from one of his usual comas. While the demon slayers prepare for the upcoming Hashira Training Program, Tanjiro recovers quickly and is assigned a solo mission: to investigate a region in the mountains where people have been going missing for years. Assuming Muzan Kibutsuji's forces are recuperating, Tanjiro gladly accepts, hoping to save more innocent lives from everyday demons. It doesn't take long for him to stumble upon a society known as the Eternal Paradise Faith. Disclaimer: This is an attempt to capture the writing style of Demon Slayer and its creator, Koyoharu Gotouge. While it may not reflect my personal storytelling style, my goal is for it to feel like a legitimate 8-12 episode Demon Slayer arc. That said, I include my own writing style flair and take ownership of any original characters and the plotline itself. Please also note that there is some overlap between this arc and a couple of others, specifically the Swordsmith Village and Hashira Training arcs. OR: Taking on another Upper Moon so soon? Tanjiro was seeing stars just thinking about it. AKA, Tanjiro gets trapped within Douma's cult and must strategically fight his way out. And yes, the Tanjiro vs. Douma fight will probably end exactly how you think it will. And no, I will not be killing our main protagonist.
Demon Slayer: A New Enemy by TroyAcapen2
29 parts Complete
What if Muzan wasn't defeated and instead pulled a trump card in order to save his own skin? A new king destined to bring terror once more. What if some of the uppermoons were cured thanks to Tamayo's cure efforts? A new ally arises to help the fellow slayers to defeat a new enemy. Note: To those who don't know Demon Slayer, watch the anime and/or read the manga. Because it wouldn't make sense for the new readers. I do not own the Demon Slayer characters nor the story. I used it as a reference to maintain the continuity of the story with a few changes in this AU fanfic. Also I own my original characters here, and there will be spoilers up ahead.

"I've lost my hope and my kind heart thanks to you. I may have ran away before, but I won't anymore." The sun had rosen and Muzan was gone. However, there was a cost to this. Tanjiro Kamado had turned into a demon thanks to his cells and is now immune to the sun. His sister was killed trying to save him, and the Hashiras and his friends around him were on the verge of death. However, instead of killing them, he kept them alive. But at what cost? By turning them into demons. They were under his command now, as the new Twelve Kizuki. And him as the new Demon King. His kind hearted side was gone, and now replaced with a cruel and sadistic side. Everyone else was dead around him. Except for one person. Taeko Miyazaki, who was amongst the battle, had been helplessly watching her dearest friend turn her other close friends into demons, and having them under his command. However, instead of fighting... She ran. She ran away from the battle, and away from everything behind her. The master's son, who was now the leader of the Demon Slayer Corps, has found out about the situation, but also Taeko's disappearance as well. However, when he meets her again, she is not alone. However, Taeko has lost most of her hope in saving her friends. The only thing she could do is to prevent that from happening again in the future. Her pure hearted side still remains. However, there was also a cold, stoic, and vengeful side that she had shown. And the new Demon King, Tanjiro Kamado has recently found out about her disappearance as well. And he wants her to join him. And if she doesn't, he'd kill her.

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

Cover created and drawn by me 💞 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The fight against Demons had gone on for as long as anyone could remember. There was never an end in sight. The Demon Slayers continued each day working to chip the number in hopes to rid the world of the biggest threat; Muzan. Nothing ever changed in their lives. At least, not until the day a new threat made their presence clear. A demon far more dangerous then Muzan himself! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This story is a Demon Tanjiro, who is an Uppermoon. The cover is what he looks like! (I love a motherlike Demon Tanjiro!) 💕

27 parts Complete Mature
You became a pillar way before tanjiro and Giyu met, so this was like basically the beginning in the demon slayer anime/manga. You are the blood pillar that has a demonic sword that needs blood in order to do blood techniques and breathing. You have an X shaped scar on your back which came from a demon trying to hurt you when you were little. You master 10 breathings...... When you see the Wind pillar you instantly felt uneasy and weird inside which to your understandings didn't make sense till later . you had demon blood in you because of the sword itself so your immortal...But luckily the Hashira accepted you because you killed an Upper moon and didn't even attempt to eat human flesh and the fact that you sacrificed your humanity to weild such a sword to slay demons with. But little did you remember that you lost your humanity completely at a younger age due to unknown events. You forgot this memory and only thought you lost your human side to the sword itself DISCLAIMER: This story will contain gore, strong language, touchy subjects, Those touchy subjects will bring spoilers to the manga!!! It will also contain some Mature content later on in this series!!!! S P O I L E RS! this is will be following the manga/anime at most parts but ill be changing it throughout.
