This is going to be in a school setting. (I do not own demon slayer or it's characters! This is a Yandere fanfic.) I will also be using female pronouns

Where a girl gets sucked into a simulator where her favorite anime characters are in. (Yandere kny x reader)

It was the year 1964, and coming from a poor family, it wasn't a suprise to you that you were engaged to a man you didn't know. You soon learned that the man you were engaged to was a rich man, and he was to be the heir of the KNYTech Industries. "Hello... My name is Y/n L/n..." you spoke out. He stared at you, his cold eyes making you nervous. "...My name is Yoriichi Tsukiguni." he replied, you glanced at his handsome face. You quickly looked away and blushed as he caught you staring. You were ready to accept all his imperfections but... Nothing could ever prepare you for his darkest secret. (No supernatural/fantasy AU.)

"...pure insanity..." "What was that, darling?" Cold, love struck eyes stared deep into hers, boring into every inch of her body, staring deep into her eyes "You..you're all psychotic killers..! I....IHATEYOUALL!!! DONT GET ANY CLOSER FROM ME YOU HAVE ALL HAVE GONE MAD!!!" "what a brat, I'll teach you how to act r i g h t.." In which a girl named y/n has found herself in the anime Demon Slayer after creating a massacre of her entire high school or for others may call it, 鬼滅の刃 The horrific storyline of demons and humans, some being demon slayers, working in the demon slayer corps, getting missions constantly to kill these demons with Nichirin swords. While on our little y/n's journey, she meets various characters, including the main antagonist and protagonist. Through out her journey in figuring out and getting used how this new dimension works, as being just being teleported into her favorite anime. Although, the feeling that characters have been acting really...how should I describe it... Unsettling Be prepared for what's about to come Y/n... (Slow updates)

"What?? Thats it?? I don't end up with anybody?!? Ugh this KnY dating simulator is bullshit!!" I complained and looked at the time,It was 4:50 in the morning. I sighed,"I can't believe I wasted my time for this... I have work in 6..." I soon walked up to my bed and grabbed every minutes and hours of sleep I could get. "Hey Y/n....." A voice says,calling me. Ugh what the fuck I'm sleeping go away,its probably mom. "...Y/n.." Wait what the fuck I live alone YEEETT!!! My eyes shot open to reveal Tanjirou calling out my name, "Thank goodness you woke up... Class is about to start. Wait... Why.. What.. When... WHAT THE FUCK?! (This story is in a modern time.)

Y/N was just an ordinary person from the 21st century, she didn't expect to wake up in an anime where human-eating demons roam free every night. Well, what's left for her is to learn how to use a sword and help the protagonist make his sister human again, who knows if she can get back to her world like this? Little did she know what was coming in this world that wasn't even hers. ❀⊱┄┄┄┄┄┄┄┄┄┄┄⊰❀ ❀ - STATUS : ONGOING ❀ - DEMON SLAYER BELONGS TO KOYOHARU GOTOGE ❀ - COVER ART DOES NOT BELONG TO ME ❀ - ON QUOTEV UNDER THE SAME NAME

when a person gets sucked into their favorite anime, my hero academia yet the characters are acting...weird. (Yandere mha x reader)
