That's why I'm going out! There is a way out and it happens randomly! People don't vanish in thin air, they must be finding the exit, maybe it's a portal or a magic hole or whatever but it changes places and moves randomly! Besides, maybe Shun has been brought here but no one knows yet, he's a baby, he can't even say his name yet! If going out and try to find it isn't a good option what's your idea?
