Remember when the Comedic Duo were in Undertale? Well, this time, they return back to the Underground, only this time, things are very different the moment they fell into the hole and landed on top of some flowers before meeting Flowey with a country accent, then a goat woman, who had an unhealthy obsession with snails, Sans being a total retarded acholic, Papyrus being annoying and likes Sans' jokes, Undyne secretly being a softie under all that armor and can't resist the sound of a nearby ice cream truck, Alphys being a Lisa Simpsons type of nerd, and so on. So it looks like the Comedic Duo will have to find a way back to their own universe with the help of Genderless Child and a strange being from another world that speaks in a strange unintelligible language and a cutie little doggie the duo adopted named Toby Fox. But who knows what kind of hilarious shenanigans the Comedic Duo will end up in the Undertale Realistic universe.

Okay, so. My first idea for this story was what if Overhaul was in HH/HB? But then I realized that would be really difficult to make their stories make sense with each other. So I decided I would make something similar but without the whole quirk debacle. And that's when I came up with this story. Just a heads up, this gets really scientific in some aspects and I'm not sure if they're entirely true, I tried to make them as accurate as possible so they might be a bit complicated. I'm always open to new ideas by you guys, so if you want to help with this book's progression, Dm me or leave a comment. Anyway, thanks for checking this story out. I hope you'll stick around for its development.

No clue where I am, no memory of how I got here, no sign of my parents and no way to contact anyone for salvation. With only the clothes on my back, it appears I'm forever lost in the forests of this new unrecognisable world with only the tools I can make myself to survive the harsh conditions of the wilderness. ...Or so I thought, until I met her.

As a servant of Ars Goetia family, one must have a strong will, the grace, and skill of a gentleman. No matter if it's in the human realm, one of the nine rings, or the pearly gates. One must do what they can to ensure the Goetia's status remains unchallenged.
