Raise a character to level 32 in World Tour mode. When you reach the last stage (in Japan), either win or lose; it doesn't matter as long as you get to the ending credits. Save the game and your character should now have an asterisk (*) next to him/her. Go back and beat the arcade mode with that character without continuing to receive the 6th ISM-Plus, "Guts". This raises all of your stats slightly.
