Astarotte, the Second Mortal Sin, is a net idol with a decent following, but Lucifer is ready to take her on with her own performances. Lucifer has a different style than Astarotte, starts to outshine Astarotte. As the crowds get bigger, and more is on the line for both Demon Lords, just who will come out on top?
At this rate, Onee-sama is going to lose!
Da wird mein Herz
noch verlieren!
¡A este paso, Lucifer perderá!
¡A ese paso, Lucifer perderá!
Luci chérie va perdre,
à ce train-là !
Di questo passo la Mia Signora finirà per perdere!
Se continuar assim 
a Onee-sama vai perder.
