Okay. I've decided. This is an Undermafia Sans x op!reader. You are amazing at hand-to-hand, and you weapons of choice are blades, but you can shoot a gun well too. You are fast, agile, strong, and very smart, but you have one problem. This is a world involving Monsters, and their Magic you can do nothing about. That was, until you found out a truth about yourself you never even thought to consider, and your mind had blocked from your past.
