Fragile is another one of those Japanese releases where it's pretty clear that someone in the marketing department decided to stick the word "RPG" on the box for sales purposes. Your character levels up, but aside from that, there's really nothing RPG about the game.
Within the first few minutes of starting play, you learn of main character Seto's goal: to make his way to a red tower far to the east. There, he'll apparently be able to find another person. This is a big deal, because aside from Seto, the world appears to be populated by nothing but ghosts.
