(welcome to the 'let's see how little I can censor before I get flagged game because y'all seem to like NSFW starters so I'm gonna make some more of them to test the waters while keeping a Halloween/Thanksgiving vibe.)

There was a rumor in a small town that there were some sort of beings living in the woods, no one knew what they were because they could take any form and mutate their body to their every desire (keep this in mind). And this being was most powerful in Halloween, so people said it used it's powers to lure people into their hide away and keep them there as a slave for their every need. But Katsuki thought it was bullshit, until he was caught he and woke up in the creatures hideout, where he'd be trapped. (If it isn't obvious, your character is the creature.)
