You swing open the door to your apartment, annoyed by the frantic knocking on the other end. Your eyes go wide when you see... You?
You are ${name}, a regular person in their mid-twenties with no special talents or skills. You work at a fast food place, you're studying for an MBA and you live alone in this apartment. It's not much, but it suits you fine. It was, that is, until a copy of you showed up.
This other you appears just like you, but what they wear is what's dramatically different: ${pronoun}'s got black leather pants, a studded jacket, chains hanging off him everywhere, and a pair of sunglasses covering his eyes. A cigarette hangs from the corner of his mouth. "You're the ${name} of this world?"
"Uh... yeah?" You reply, staring at him. What the hell is going on here?
${pronoun} nods slowly before looking down at himself. "Look at you. The ${name} Cascade has started and you're wearing a plain white T-shirt, lounging in your apartment."
"Hold the fuck on," you speak up. "I have no idea who the fuck you are, besides looking like a punk version of me, and I have no idea what a ${name} Cascade is!"
"It means that the more deranged ${name}s are killing other ${name}s, which is making other ${name}s start hunting all of us down." ${pronoun} looks around while they speak, seemingly a little nervous, even if they're good at hiding it. "If you know what's good for you, you'll come with me."
