Acquired by getting a AA on the default Extra Stage song The Legend of MAX, which is played using modifiers Dark, Reverse, 1.5x, and No Recover (the life bar, which usually starts at about 1/2 full and grows with the player's score, starts at full strength, and the player cannot add to this bar; only lose from it).
Usable as well as "Oh My Emmett" (also from Twilight.)
Alice: OME, They're so CUTE!!
Edward: Hang on...That's me. O.O
Ome: Life is like so totally super perfectly super duper awesome-like!
OME Arturo!! I thought it was sold out, I'm so excited now!
