Kaigaku Stories

What if Tanjiro became a demon instead of Nezuko? What if the strongest demons became the protectors, and the strongest slayers became the monsters? This is a Kimetsu no Yaiba Swap AU. This will be a similar plot to the manga/anime. All characters belong to Koyoharu Gotouge.

It was too late Muzan has taken over Tanjiro's body and because of this everyone has died, all but one. Little did anyone know, one survived, an infant, the son of Nezuko and Zenitsu. This son will be the one to set things right, the one who will change the future, his name was Denki. God pitied Denki, and when he wished for things to be different, that he could meet his parents it was granted to him. But not in the way he expected. Denki was traveled back in time before everything happened. The time, he could set things right, fix everything and more importantly meet his family

This is going to be a story based on Kaigaku and Gyutaro because I really enjoy the ship. This story will be set in the modern AU.

Kamado Tanjiro meets a new student called Zenitsu Agatsuma. Well, our little blondie here is sadly diagnosed with Fluency Disorder, it basically means you'll stutter or your words will get blocked when you speak, from a recent accident. Due to this disorder, Zenitsu doesn't speak in school, afraid others would judge him for being different. But knowing Tanjiro, he will do his best to help Zenitsu overcome his fear. How will Zenitsu react with Tanjiro's overly protection and kindness? Hi again! This cover art isn't mine, so a big thanks to the person who drew this beautiful art! This story is inspired by a Chinese/Mandarin comic book called 《高塔公主毕业纪》by Bunnysama. Also yea I got motivational support from my friend to start another story :) Also I changed the title. Is it better?? ❗️DiScLaiMeR❗️ 1 I don't own any of the Demon Slayer characters, they were made by Koyoharu Gotouge. 2 Kaigaku is a good brother 😀 3 This is a school AU 4 This contains bl (boy x boy) and some fluff! I'm still thinking whether to do smut or not since I've never written it before 😚 5 Hope y'all like it! 6️⃣7️⃣

After defeating Muzan, Zenitsu finds out that he has feelings for Tanjiro. He feels that he is unworthy of someone as brave as Tanjiro so he leaves butterfly mansion. Two years later all the slayers who worked under the demon slayer corps are called back due to someone reincarnating Muzan. Zenitsu who was no longer a cry baby is reluctant to return but has no choice when the village he calls home is attacked by a demon. He returns in a female attire under the fake name Zera Yoshikawa. #inogen-1- 29/4/24 #tanzen-1-18/8/2024 #genya-1-4/9/2024

"Hanaru que escapo de un demonio junto su hermano menor y se convirtió en la única aprendiz femenina de su maestro Jigoro desde ahí conoció ah un joven de su misma edad llamado Kaigaku el cual cambiaría su vida por completo" Advertencia: Este fanfic aunque no es tan fuerte va ah contener faltas de ortografía, escenas explicitas, obsesión(leve), violencia. No me tiren hate ya que este fanfic se tratara de Kaigaku y pues yo se que es un personaje muy criticado de Kny y que ah muchos no les cae bien pero yo quise hacer este fanfic ya que era una idea que tenia desde hace mucho tiempo y pues quería hacerla pero no tenia tiempo y ahora que puedo hacerla pues aprovecho las ganas y perdón si deje mi otra historia sin terminar tal vez la continue no lo se... pero les quería pedir perdón por haberla dejado inconclusa.

Disconnected cus idk what to do with it, sorry but I might rewrite it again one day, I was planning to but gotten to busy. From being the first generation to pass down the hinokami kagura in his family, to be reborn over 400 years later into the same family as a twin. Kamado Sumiyoshi who once lived in the Sengoku era, now is reincarnated into the Kamado family again but this time he has a twin brother. Sumiyoshi doesn't remember anything younger than 6 years old because when he remembered his past life he forgot his current reincarnated life. With the knowledge that he has of hinokami kagura can he teach his twin how to use it properly or will he be too late or even will there be no use for him to teach it to him properly? I do not own any image, most found on pinterest, unless stated otherwise I'm not sure how well this sounds but the actual thing is better than the description. This is only the second fanfiction that I've written on paper- well technically online- all the other ones are in my mind that will probably never be seen by others.

ALRIGHT MOFUCKAS THIS IS AN UNDER APPRECIATED SHIP AND THERE AREN'T ENOUGH STORYS FOR IT SO HERE WE GO None of the art is mine

In this story instead of Tanjiro being the older brother he is the younger brother (He's also the one to get turned into a demon by Muzan) Nezuko is basically the older sister in this Story.Basically the Hashira are different Shinobu,Giyu,Sanemi, Muichiro,Mitsuri,Obanai and Gynoemi and Yoriichi are all demons while Gyokko,Nakime,Daki,Gyutaro Kokushibo,Douma,Akaza, Hantegue, Kaigaku, are the Hashira's. And the Lowermoon Enmu (Lower moon 1) Rokuro (Lowermoon 2) Mukago (Lower moon 4) Rui (Lowermoon 5) Kamanue (Lowermoon 6) Kyogai (New Lowermoon 6) Are all Demon Slayers

This is will showcase the uppermoons :)) Just a chatfic with the reader and the uppermoons including Rui and Enmu. When you opened up your messages you saw a groupchat you didnt know. So being the dumb person you are you started texting the the group chat.

so In this new story it's just doumas daily thougths ig, since i hyperfixionate him a lot and I felt like writing about how I feel. so this is kind of a vent book, and no one has to feel bad for me!! pls just look at this if it's just a normal book about douma. ty <3 contains: mentions of sh? death mentions vent sensitive content

*Old story, I made a new one* Lady Tamayo's poison turns Muzan into a 3 year old child instead of what orginally happened. I thought of this idea on my way to school so I decided to write it, sorry if the characters are out of character I don't usually write hashiras.

Also from my GakuKai drabbles book, which I deleted

My friends are gonna kill me 😅 In this story, Zenitsu is dating Kaigaku(not related obviously) Kaigaku is abusive though so TW! Tanjiro and Zenitsu meet at some point. Also not sure where the story is going, I'm just rolling😃

This story is inspired by one of my baddie bestayys @Um-Hello-World go follow her now or i will get u a goat for cristmas and fuck it (っ◔◡◔)っ ♥ NOTE: These are all my opinions, some canon ships will *NOT* be included! ♥

'Magic is drying out, and its servants are almost gone. The few left, called endlings, are in hiding or captured by humans...' An original story using Vocaloid characters (Kaito and Gakupo), in this case blending fantasy and some sci fi elements. I have no beta for this, let me know if you spot any weirdness.

A story in which twins are taken from their home (A demon slayer AU) (⛔TW⛔ Abuse,Blood, minton's of R@pe, and kidnapping)

Muzan Kibutsuji is known for being heartless and anger,but he can't help but feel delighted whenever he sees his uppermoon 3,what is this feeling?... First book on Muzan x Akaza!
