Despite Giorno wanting to find Fugo, Abbacchio decides to go look for the key, since that was their mission. However, once Abbacchio finds the key, he also gets dragged into the mirror world...
We defeated him, so his ability disappeared!
!زالَتْ قدرتُه بعد أن هزمناه
Wir haben ihn besiegt und
seine Fähigkeit wirkt nicht mehr!
¡Su poder desapareció
porque lo vencimos!
¡Su poder desapareció
porque lo vencimos!
On l’a négocié
et on a supprimé son pouvoir !
L'abbiamo sconfitto, e il suo potere
è scomparso di conseguenza!
Nós o derrotamos e o poder
dele parou de fazer efeito!
Он погиб и его сила испарилась!
