INTEGRITY'S FALL by KylerArts

Summary
As Of Right Now, This Is A BACKUP For My Visual Novel Integrity's Fall, Which I Will Re Format For Ao3, But For Now This Is A Direct Copy&Paste From My Google Docs, Pending Rewrites And Some Sections I Never Wrote In The Docs, But In The RPY File Itself. Those In Particular May Still Have Some Of The Scripting Until I Can Reformat, So Pls Ignore That '>w<
If You Read Anything, READ THIS As It's Important!
I.F Is A Furry Romance Visual Novel, Meaning Like Its Peers, It Has Multiple Choices In Regards To Its Romance Paths. This Is Still Present Here, Though A Little Scuffed. When Presented With A >CHOICE< You Will Find Big Chunk Of text Between The Name Of The >CHOICE PATH< And The >END<So For Choices You Didn't Pick, Scroll Until You Find The Path You Did Pick. For Example, If You Picked Clase In Chapter 1, Follow The Clase Path By Skipping Past >RYDER PATH< Until You See >END< And >CLASE PATH<
That's What You Read. ALSO, If You Pick >NONE PATH< You Will Be Given More Options Later In The Game. Sorry If Its Confusing, But This Is The Best Way Ive Thought Of To Translate A Multiple Choice VN Into A Google Doc, And Thus A Text Format Applicable To Ao3

Summary
Mettaton is experimenting when something goes wrong and he causes himself to split into his major personalities. The splits have to be reunited before the unknown amount of time passes that will cause Mettaton to disappear for good.
- Um guys I wrote this cause I'm obsessed with the episode Nevermore from Teen Titans. Uh anyway. This fic is, like 75% comedy 25% feelings. I'm an ace trans man who relates too much to Underlust Mettaton, so I had to write this because none of you understand my vision!!!!! (That I have never said anywhere ever...)
Also, yes the title is terrible but I came up with it when I started writing 2 years ago (dies of executive dysfunction) and now I'm emotionally attached to it.Series

Summary
There have been a lot of rumors floating around recently. The barrier shattered, "fallen down" family members returning, true hope for the future of monsterkind... things like that. Things much too good to be true.
Everyone around Ceroba believes it all without question, and eventually she's pushed to investigate. But maybe those rumors aren't as false as she initially believed. Maybe she was a bit too quick to judge.
And maybe she can see the Surface. Maybe she can see her little girl again.

Summary
Not all monsters were forced underground. Multiple monster species were able to pass as human or at least hide away from the mages that ended the war. Over the years they faded away to human myth, along with the mages, but secretly they were thriving in their own communities. When the underground monsters were freed and integrated with human society, the surface monsters had a decision to make: do they come out of hiding and stand side by side with the underground monsters? Or do they stay out of the spotlight as they’ve done for so long?
Reader is a surface monster. She's on the run from her former clan and decides to travel to Ebott City to plead to King Asgore to become one of his citizens so that she'll be able to easier hide from the group searching for her. She ends up under close watch by the skeletons until they can trust her to not cause problems in their city. Reader is named, though her name changes in chapter 2. She has a physical description as well, so I guess she's more of an OC but the story's still told in 2nd person.

Summary
An incredibly short attempt at writing a "horror" story. Basically, Frisk gets absorbed by Endogeny graphically. It takes like 3 minutes to read. It's very badly written since it was wrote at 3 in the morning. If it doesn't make sense, that's why. ⚠️ Does contains depictions of gore and death

Summary
Frisk killed them all, to be able to reach an ending. To be able to stop. Chara-Chara was mislead. They thought this was for the sake of mercy.
Chara will be the one who controls the timeline. Chara will save everyone. Chara will make up for everything that Frisk has done.
Frisk-Frisk will be tucked away. Somewhere unimportant. Somewhere they can never hurt another person again. (Is Frisk really just-rubbing themself against an edge-It does not matter. Frisk does not matter anymore.) -

Summary
Frisk finds themselves in Alphys's lab. However, things go off the road the original game had planned. Think of it as... a lesson in what not to do with Determination.
