In the midst of an alien invasion, Scaramouche has been your friend since the beginning. You both found yourselves in a confinement, almost in a cult, where you would sing to entertain the aliens; and basically to survive. Now, the aliens have created countless 'Alien Stage' competitions. And now that you have won your first round, you must sing against Scaramouche, your own friend, maybe even some kind of soulmate, in your second round. Where only one of you must win; and the other must die.
