When you first start the game, wait for the “PCCW Japan” logo to come up. When it does press and hold L1, then rotate the right analog stick five or more times. You’ll hear a confirmation sound when the code is entered correctly. This will unlock the fifth character Iria in story mode. It will also unlock all the characters in duel mode, as well as an all new mode called “Full Attack”. This mode plays pretty much like story mode, but when you continue you have the option of changing characters. You also get a sixth bonus character in “Full Attack” mode, Alicia the fallen angel. Once this code is entered you can save your game and everything will remain unlocked on your game file.
At PCCW Japan logo screen, press and hold L1 and rotate the right analog stick 5 or more times.
Unlocking More Characters In Duel Mode
To unlock characters in Duel mode you must beat the game with at least one character on any difficulty. After that you get the option to save. Save the game and then the next time you start a Duel game, you will find that most of the monsters you encountered previously will be characters that you can use in Duel mode!
