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.
It all comes down to what went down 
at this Colosseum before we got here.

المُدرَّج قبل أن نصِل إلى هنا
Die Frage ist, was im Kolosseum geschehen ist,
bevor wir hergekommen sind.
Todo depende de qué pasó en el Coliseo
antes de que llegáramos.

Qu’est-ce qui s’est passé
avant notre arrivée au Colisée ?
Dipende tutto da cosa è successo qui
al Colosseo prima che arrivassimo noi.
Depende do que aconteceu no Coliseu
antes de nós chegarmos.
Что-то произошло перед тем, 
как мы попали в Колизей.
