Final Fantasy XIII : Agito
The game is set in a magic school named Akademia and will gradually expand to the larger world outside of the school. It is described as an online RPG, but not "massively multiplayer.
There are thirteen characters revealed, 12 of whom appear to be students. Weapons include longsword, katana, handguns, a shotgun, a mace, a bow and arrow, a spear, a scythe, an extending flail, bare fists, a flute and a deck of tarot cards. The thirteenth character is a Moogle used in previous Final Fantasy games. The character with the deck of cards has been revealed to have a greater importance than the other characters (shown in a pamphlet at the 2006 Tokyo Game Show).
