Why am I the last person on Earth?

Okay, that was just a joke on a new game I got called "The World Ends With You." It is really weird. You are a boy namedNeku Sakuraba, and you just do your own thing, not caring about other people, wishing they were gone. Then you wake up in the crosswalk with no memory except for your name. And suddenley some frogs appear, and they try to kill you! So you run away, and bump into Shiki Misaki and you fight the frogs, known as noise. You make a pact, and then start on your adventure in the Reapers Game.
