NewGame+, Grade Shop, And Hidden Dungeon.
     Get through the game and at the ending after the sequences, youll
be  able  to  move  around and go places, but theres no enemies in the
world  now.  Head  to  the place where you originally meet Reala (lens
girl) At the first forest dungeon.

     From  there, An FMV Sequence will play and when its over youll be
asked  if you want to save. Save your data on another slot and then go
to the loading screen and load it.

     When  you load youll be at a shop where you can spend all of your
grade  points  that  you  earned  for  extra  features  such as Double
Experience, Carrying over extra items, Stats, and other things.

     Along  with NewGame+ Giving you access to the Grade Shop, You can
access  a  new hidden dungeon by collecting the 15 Unlucky Stones that
now exist in the world.
