Nezuko meets Sans Aus? by AmIsChill
Fandoms: Undertale (Video Game), 鬼滅の刃 | Demon Slayer: Kimetsu no Yaiba (Anime)

Summary
I was bored, and this is just Nezuko from Demon Slayer (KNY) mysteriously (for whatever reason) teleported into the Undertale Aus multiverse.
Wattpad version has (more) images and updates more(?) often https://www.wattpad.com/story/295407214?utm_source=ios&utm_medium=link&utm_content=story_info&wp_page=story_details&wp_uname=Is_Am_CHILL&wp_originator=%2FPGItqzLCv68gDBNf12ZT9ARb2ev2f3sIr2CR6fW%2FCNjveXPJlBXjW03v13tQ8prDN8dIKR2DoFxuK9ybxIGaFokJmQU%2Fl%2B4Y09mAWQRPMIzg%2FSuM9R0mQJofMLI%2F9Kc
And yes, this Ink knows multiple languages. This is a branch-off from my videos with Sans AUs reacting to Demon Slayer on my YT channel. (Cringe, I know) you don't need to watch them, but the story will make a bit of sense (?) all you need to know is that some of the Sanses have a slight idea about KNY
All characters go to their respective owners, and I don't own any images.
You can look up AmIsChill on YouTube for OLD cringe reaction vids

Your were well on your way to your masters degree, or at least you were until your mom skipped out of town and left you to take care of your drunk of a stepfather and your younger siblings. You could have said no, told Jerry to clean himself up and be an adult, told off your mother for not taking the kids with her when she ran from her abusive marriage.
But then you’ve never been one for talking very much. The thought of talking back to the man who labeled himself your father… well you’ve seen what happens.
So now you’ve given up your future, your half finished degree and research papers all but forgotten as you play housewife and stay at home mom for your younger siblings, shielding them from as much of it as you can and trying not to embarrass yourself in front of the sweet goat woman and funny skeletons that moved into your building.
Oh yeah, Monsters were a thing now.

"Protect humans and keep them safe from harm, no matter the cost."
Sans had made a promise, and he was prepared to go to any lengths in order to keep it.The short skeleton refuses to let you go because you'd only find danger outside the Snowdin village. He loathed himself for poisoning your drink in order to make you weak and sick so that you can't leave the safety of the town. It was a horrible thing to do, but this way you would stay with him and Papyrus.
He'd keep you safe and happy.
