Completion bonuses: Successfully complete the game and save. You can reload
a saved game at a point before the final Boss then go to the world
map to access a location called "Old School Building".
A section inside there is called the "Forbidden Zone".
There is a teleporter in the dungeon that can be used to access
a bonus dungeon. The bonus dungeon has powerful monsters, an alternate
stronger final Boss, and an appearance of the Boss from Atelier
Iris 3. Additionally, your cleared saved game file will unlock
the "Extras" option at the main menu. The "Extras"
menu has "Gallery", "Database", "Music",
"Cast", and "Endings" options. Note: Each
subsequent time the game is completed, more endings will appear
in the "Gallery" and additional entries will appear
in the "Database".
