Diablo and the others are locked up in the sanctuary by Vishos and kept apart from Lumachina.
Meanwhile, Horn managed to escape, but she's torn between her desire to flee all by herself and her desire to help her friends. That's when Babalon, the Level Up Goddess that resides within the Holy Grail, appears before Horn.
If we eliminate the Head Priest along 
with that Demon Lord, we'll be secure!
Wenn wir diesen König der Dämonen und die
oberste Priesterin gemeinsam auslöschen würden,
Se facciamo fuori la Somma Sacerdotessa insieme
 a quel Re dei Demoni, saremo salvi!
Se eliminarmos a Madre Principal e
aquele Lorde Demônio, estaremos seguros!
