Yup! They're back! A thing I started back in my older account UndertaleKyannaKitty.

They're your siblings now!
Cute, edgy, as much angst as you want, sad-whatever!

Hi guys this is a new story based off of the game undertale. Also this is my first fanfic I have ever written so I hope you like it. Frisk is 13 and so is chara. Sans is 130 which basically means he's 13 in monster years. Papyrus is 160 and toriel is 170 aka 17. Undyne is also 170. Mettaton is a girl. Alphys is 160.

Smol thing I guess. I don't own Undertale (obviously), but I do own all of the art in this book (as the first A/N states). This is my first fic. I update as often as I can, especially on most weekends. Don't be afraid to comment if you have something to say.
Reset (Sans x Older!Frisk) by error-code-707
18 parts Complete
There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

Undertale:Secrets by ItIsComic
34 parts Complete
Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!

For many years, Frisk never once knew about Valentine's Day. What?!! That's probably what you're thinking. Anyways, Frisk has a huge crush on a certain skeleton who's also crushing on someone else. Will she be able to confess her love to him and live a happy ending? Also...Frisk is a girl in this story ;) UNDERTALE DOESN'T BELONG TO ME. IT BELONGS TO TOBY FOX. None of the used pictures&gif's are mine. And that's about it. Plz follow, vote, and comment in my books. I'll be happy to hear from you. Buh bye!!!!
