    Summary

    The resets keep happening, but Papyrus is gone. Nearly six years of grief have warped Sans, causing him to risk his soul with self-destructive behavior and making him all but unrecognizable to his old friends. Any day now, he expects a reset that will bring him far enough back in time to reunite with his brother and erase his sins. In the meantime, he'll distract himself with Muffet's new call girl...

    You need a lot of money, right now. Unlike the majority of humans in the slums of New Ebott, you don't have any anti-monster prejudice, and you're kinky, submissive and enjoy sex. You've heard someone like you can do very well for herself, catering to monsters. Now here you are with your first client, a skeleton monster in a suit offering you a drink from a hip flask...

    Undertale gangster AU with a 1930s-era American aesthetic, essentially because I like the clothes. Status updates and story chatter at http://neroli9.tumblr.com. Also, come chat with other APJFM fans at the APJFM Discord server!

    Summary

    You watched him unwrap his lunch, pouting.

    “C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

    Summary

    I'm not so good at finishing long stories, so I've decided to try my hand at One Shots. Prompts and Requests are welcome. I also might do sequels to any chapters that get lots of love.

    It's been a while since I've written anything let alone shared it. Please let me know your honest opinions. I want to know the good, the bad, and the ugly. I can't improve if I don't know what needs fixing.

    Summary

    New York City in the late 1920’s is an exciting- and dangerous- place for a young woman like Frisk. She’d’ve rather stayed behind in her hometown but she’d promised to watch over her dad for as long as she could and she intended to keep that promise. With the police force slowly being corrupted by Mafia money, and an old friend suffering from an unspeakable trauma and a hard life, she’s found herself set up for quite the ride- one she is not looking forward too. Besides, it’s not her fault- not really; who could think with those eyes boring into her like that all the time? Why was he everywhere she went? Why does it look and feel like he wants her gone? If only the dreams would stop keeping her up at night... If only the ache in her heart would cease for one freaking moment, she might have time to make a plan.

    Summary

    Money. Murder. Jazz. Liquor. This damned city had it all. Every cranny had a crook and every gutter held a beggar. With your history, though, you couldn't be picky, scrapping dimes off dirty tables and counting blessings instead of wages. But, it could all turn around in a night, when you decide to move into a new boss's territory, a gang of monsters known as the Gasters. No protection fees and no catch... you decide to get to the bottom of it, and the Don on the block isn't too happy with that. You've been lucky for the last three years, but your luck is about to run out...

    Summary

    1920s, Manhattan, New York; 100 years after the Monster War and the Peace Treaty was signed- allowing monsters of all shapes and sizes to reside on the surface and make a life for themselves and their families. There is still plenty of prejudice against the monsters in these current times, as there is prejudice against anyone different or uncommon within the world as a whole, but times are changing and humans are adapting. There are those in this city who wish humans would adapt much faster and have since established political groups and parties in an attempt to push their own agendas for civility and equality through polite presentation and example- there are also those who see such things as slow going and wish to speed things up on their own terms; no matter how dark and underhanded those terms may be.

    Enter the Reader. One, bob-haired, female reporter plucked from the countryside with hopes to make it big in Monster Manhattan and the great wide city beyond. You've done your best so far, landing a gig at 'The Tribunal', a small paper company from the lower eastside, but you're ambitious and determined, and you're hungry for more.

    Let's hope you haven't bitten off more than you can chew.
