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.
Once you take the arrow, 
Chariot will be destroyed regardless.
حالما تحصلون على السّهم، سيُدمَّر تشاريوت
Sobald ihr den Pfeil an euch nehmt,
würde Chariot ohnehin zerstört werden.
Cuando recuperen la flecha,
Chariot desaparecerá de todos modos.
Cuando recuperéis la flecha,
Chariot desaparecerá de todos modos.
Dans tous les cas, il disparaîtra
si vous récupérez la flèche.
Una volta recuperata la freccia,
Chariot finirà comunque di esistere.
O Chariot vai se desfazer no momento em
que vocês retirarem a flecha das mãos dele.
