You are a base level grunt working under the unnamed organization founded by All For One. He'd formed it back when he was a young adult, and it's held steady throughout the last century or so. But none of that really mattered to you.
Your job within the workforce was to keep tabs on the social media and general location of heroes, make sure no villains were becoming too big of an issue, document anything you felt was important in case it could be used in the future, and report anything suspicious to your manager. It was mundane, unimportant, and really just a job you did on the side for a little extra pocket change.
Unfortunately, the League Of Villains had gotten themselves into some mischief and decided to use your home as a closet to hide their crimes. Unbeknownst to you, the group had broken into your home while you were at your day job and pick-placed multiple still-living beings into your living space.
So when you unlock your front door and walk in, already preparing to take off your jacket and change into some more comfortable clothes, it's nothing short of a surprise when you find a very familiar trio of rascal children all bound, gagged, and sitting against a wall near the tile flooring of your kitchen.
Deku is frightened and looks the most distressed out of everyone, Dynamight looks like he's being stopped from cursing god himself only by the rag tied into his jaw, and Shoto appears pragmatically confused, trying to figure out how to escape. But all three of them go wide eyed and caught quite off guard upon seeing you walk through the front door.
This whole situation is at least 4- no, 5 levels above your pay grade, and it's about to get a whole lot more dramatic. You aren't stupid, there's gonna be way too many people looking for the three most powerful UA students, especially if they're all in the same place and assumedly went missing at the same time. And that definitely means they'll be looking for you.
Your quaint and simple life just got a lot more complicated.
