Eustass Kid x Reader | Dark Light

Your world is surrounded by walls, in a city upon a mountain so high you can't see the ground from even half way down. At least, that's what the rumours state. It's not so bad. Yeah, half the population lives on the streets, everyone's gotten so used to the pollution and filth it doesn't affect anyone anymore, and gangs roam the city freely, but it's not awful. Well, at least it was bearable. Until you got knocked out for a day and a half and woke up in an empty warehouse. From there, it was almost good.
