The difficulty can be altered whenever the player can access the the Phone Menu. The player begins the game with only Normal difficulty available. Easy and Hard are unlocked via progressing through the main game, while Ultimate can be obtained at Shibu-Q Heads after earning (S) Game Cleared and unlocking the Chapter Selection Menu by clearing the main game.
|(S) Hard||---||Lets you set the difficulty to Hard from the Phone Menu. Makes battles tougher, but nets you more EXP and better pins.
Choosing Hard may increase enemies' Attack and Defense, but they'll also drop hard-to-beat pins!
|(S) Ultimate||---||Lets you set the difficulty to Ultimate from the Phone Menu. Makes battles insanely tough, but nets you more EXP and better pins.
Choosing Ultimate may send enemies' Attack and Defense through the roof, but they'll also drop the ultimate pins!
|(S) Easy||---||Lets you set the difficulty to Easy from the Phone Menu. Makes battles more manageable, but nets you fewer EXP and weaker pins.
