On Benben's final spellcard, she shoots out two sets of musical staffs on Lunatic only. I lost the recording for normal mode, but Hard is similar except in normal mode the music staff is yellow and the bullet density.
Music Sign "Malicious Musical Score" (Hard)
Music Sign "Double Score" (Lunatic)
In Futo's final spellcard, Easy and Normal mode have the same rotating pattern, but the rotating pattern changes on hard/lunatic. On lunatic only, the rotating pattern dissolves into blue amulet bullets to make another pattern (last 2 pictures)
