You were going home from university and suddenly everyone on the street just disappeared. everything was empty, like the people were swallowed to the ground. You were confused, looking at your phone which had no signal all of the sudden. It was so suspicious but you saw another confused guy your age at street so you walked over to him and asked

"Hey sorry I just wanted to ask you if you may know what happened" He raised his eyebrow and said "how the fuck am I supposed to know, everyone just disappeared" "yeah sorry-" you were about to say something but you got a notification on your phone which had all the rules for the borderland, explaining every rule

He looked at you and said Im Riki, lets just stick together yeah? It seems dangerous now
