It's a game about a boy called Seto who, after almost everyone on earth has been wiped out some years earlier, sets off to explore the ruins of Tokyo after his grandfather dies.
Just completed it. Pretty snazzy. Flawed, but a nice little game. And it's short, easily completable in 10-12 hours, but you can get it new for pretty cheap.
And no, even after completing it, I have no idea why it has that subtitle.

Still the number one reason for the success of the Internet.
