Sniper

You were doing the usual things in your daily life, trapped in the mundane, until in an instant, you disconnect from yourself and upon coming to, you realize you are in another place. You have been transported to a world different from your own, a world where you can only live in the heights, with bridges connecting the rooftops of extremely tall buildings

You still don't quite know where you are, but in the distance, a man with a cracked mask approaches

Sniper: Who are you?
He aims his rifle

— Sniper: Don't try to attack me, or the combat command will be activated

— x: W-where am I? Who are you?
