    Summary

    [New Desc.]
    Somewhere in a suburban town is a school. In that school resides a club. A Vampire Roleplay club, to be precise. All the members were different; they ranged from a French transfer student, two spoiled siblings who had morbid senses of humor, a single jock who was only there to spend time with her girlfriend, and an overbearing nerd who was too polite for his own good. There were others, but they were the most prominent members. So what happens when these teens get pulled out of their reality and into the world they once thought was only fictional? And how will their environment, friends, and new enemies react when couple after couple forms in this world? Take a step into the vortex and find out...

    These are short stories about AUs using writing prompts I find on Tumblr. These stories can be sad or happy or whatever I want. Enjoy! Also, you should probably know that the tags are subject to change. So beware, I guess.

    Summary

    You had been raised to be a hero, to defend humanity against monsters if they should ever show, but when they do-there's no need for heroes and no need for you.

    Years later you get summoned by your old boss to help with a problem that threatens the peace between monster and human kind. Someone you knew is tearing apart the fabric of reality and bringing boss monsters from alternative worlds to yours. You need to team up with the monster mascot and his boss brother plus their softer, alternative versions to track down the new arrivals and...make nice. But is that all?

    Summary

    Edge wants religion dead. He couldn't give fewer damns, and nobody is ever gonna get him into a church... until someone comes along and steals his heart.

    Error is a technological genius who feels underappreciated, though that changes once he meets a talented young artist hiding a dark secret.

    Geno is trying to escape from the memories of his past. To do this, he seeks the help of a death-obsessed graveyard manager.

    Dream is a therapist who has exactly two clients: a depressed pun lord and a very odd but very hot writer.

    Lust is a stripper at the local club. He has one particular favorite person, and that is the local butcher.

    I am someone who will probably degrade all of this into nonsense.

    Summary

    Red wanted a better life for his six-year-old brother, so he saved his money, scored a new job and hauled the temperamental brat halfway across the city to a new apartment, far away from the cesspit they once called home. Falling in love with his punny next door neighbor wasn’t part of the plan.

    Summary

    It's been more than twenty years since you fell. You're not sure how long, exactly... long enough for six human children to fall and die in the underground.
    You've given up on saving them, almost, mostly, but you won't just stand by and do nothing.
    You won’t let another child die here. Not if you can save them.

    Summary

    Classic Sans... everyone has heard about their origin tale. The very character that ended up setting up all of their lives in their own universes and their own time. However, to any extent, almost no one has met him. The reason? Simple, there was no reason for them to. Whilst they all were able to talk to each other face to face, Classic was the one who never intermingled with the alternate universes.

    So, what happens when a chance encounter leads to all of the Undertale Au finally being able to meet the one who started it all. The very reason they too are anomalies in the grand spectrum of the universe.

    One thing is for sure, Classic will never be able to get a break.

    However, no matter how akin anybody actually does becomes to Classic, there is always something that he is hiding. All of his newfound friends and aquaintences are determined to figure out just what happens when he is not around. Why he won't allow them to go and see his universe with their own eyes.

    // Welcome to a general fan-book that is going to be written in a script format, because I have nothing better to do in my life and I am literally just wasting away here. Please help me, I am going to die of boredom... :'(//

    Summary

    After being freed from the Underground, monsters became 'bitties' as humans called them.
    Small, unable to protect themselves properly, monsters had no choice but to entrust care for them to humans,
    that were guided by toriel and asgore, always alongside frisk to ensure everything went smoothly.

    But being stuck in a bittycenter (as the carecenters for them were called) all the time became worse for him, when Sans' brother
    Papyrus left him.

    A decision made on a whim to be able to leave the center turns into quite a tedious, degrading episode, because the normally observant skeleton
    was running out of excuses and couldn't be bothered to try harder.
    His quick escape plan ends in him desperately hoping for help only to get his wish at the end.
    But as the saying goes 'be careful what you wish for'.

    Summary

    Deadluck Hotel & Casino; it’s cheap, seedy, flashy...and it’s the most popular house of sin and desperation on the Ebott Strip. Deadluck is where ne’er-do-wells, average Joes, and high-rollers alike go to take a chance on winning it big or losing everything. And, rumor has it, the monster brothers who own the place are in thick with the mob, but you were never one to listen to rumors. It was either buy a room there or sleep in an alley, so you take your chances.

    The thing is, the Devil was always a gamblin’ man.
