an average person is reborn into the world of demon slayer, at first, it sounded good, until he found out what he was

(Note: due to a friend's request, I will have to clarify this if you haven't read the story yet, this takes place in a knyverse absorbed by the nasuverse, not the other way around)

Reincarnation (Demon slayer x Male reader) by Creamyrose22

The prospect of reincarnation is defined as the rebirth of a soul in a new body. What would happen if the strongest character in demon slayer was reborn as you? Makes me wonder how a certain demon king and the world as we know it would react.
◂☆❝A heart of wisteria❞☆▸ |Giyuu angst| by IdkDontMindMe91
21 parts Complete Mature
Peace and tranquility. Most all humans wish for a life filled to the brim with it. Giyuu was no exception to that. He, much like any other people, had only ever wanted to live a comfortable life. One without hardship, and one without illness. Most people never thought to wish on the second. Giyuu, however, has suffered dearly due to both physical illness, and mental. He often times found himself wandering around at night, not heading anywhere specific. His mind is awfully foggy at these times, and so he will often feel disoriented in a way; he wasn't thinking about where he was, and nor did he care.. The cover art isn't mine! Disclaimer: none of these characters belong to me, they belong to the creator of kny itself. TW: This story contains strong language, self harm, mentions of self harm, death, gore, mentions of suicide, and suicide itself. Why does everyone keep adding my book to sanegiyuu and/or sabigiyuu reading lists..? 😭 Disclaimer, this is an old book. There is a version of it that is going to be the rewrite, and many scenes have been added and removed. If you are looking for genuinely legible writing, I would transfer to the rewrite.

32 parts Ongoing Mature
IN WHICH Y/N IS THE MIST HASHIRA'S TSUGOKU MAIN TW'S: SUICIDE, SWEARING, VIOLENCE cringe as fuck I promise I'm not weird I don't know how to write okay If you wanna know a little bit about me which I doubt you do but I'm gonna yap away anyway- I'm canadian and speak french and english. my favourite band is weezer (live laugh love rivers) also I swear on my infected ear piercing I know how to use capital letters they just look like shit with lower cases and I'd rather die than write any letter other than "I" that way- BUT I DO IN THE FANFIC ON GOD. funfact about me or morbid secret I guess: I used to make gacha club videos and text stories on YouTube of demon slayer, mostly muichiro x y/n stuff. I started like a year ago and then stopped sometime because I couldn't handle how embarrassing it was getting for people to learn that I did that, and then check it out only to laugh at me. so I deleted my videos and account. now I feel more happy and less stressed out making fanfictions and bots on c.ai ( if you want to go check those out its in my description )
