Jean Pierre Polnareff holds the key to defeating the boss. The one who appeared before him wasn’t Bucciarati or his squad, but the leader of Passione, Diavolo himself. Diavolo tries to eliminate Polnareff once and for all and summons Emperor Crimson, but then Polnareff summons Silver Chariot and it is pierced with the arrow. That’s when something happens to everyone in or nearby the Colosseum. They find themselves losing strength and all fall asleep. After waking from their deep sleep, they all realize something has changed.
That's not it. 
That's definitely not the boss's soul.
هذا غير صحيح. هذه ليست روح الزّعيم حتماً
Das ist er nicht. Das ist
keinesfalls die Seele vom Boss.
Ese no es él. El alma del jefe
no se encuentra allí.
Ese no es él. El alma del jefe
no se encuentra allí.
c’est pas le cas.
C’est pas l’âme du parrain.
Non è lui. Non è sicuramente l'anima del boss.
Aquela definitivamente não é a alma do chefe.
это не он.
