Successfully complete the game once. Press [Down] at the title screen. The words "Special Mode" will appear. Press [Start] to play the game with only the action scenes without having to use creation mode.

Complete the game, then press [Up] or [Down]x2 at the title screen. An option for professional mode will appear below the "New Game" selection. In this mode, your character has no magic and regular monsters are twice as hard to kill.
