Summary
Bucciarati's group searches for any hint which will lead to the Boss, hacking into numerous police database to look for any correspondence with the Boss' fingerprints. They find nothing, but are suddenly contacted. Bruno tells Giorno to shut the connexion, but that third party confirms that they are on the same side as Bruno, revealing the Boss's true name: Diavolo, and his time erasure power.

The third party invites them to meet in Rome, explaining that the Arrow may unlock a power which is able to beat King Crimson's time erasure power. Bruno accepts the offer and the gang confidently leaves Sardinia. They are however spotted by Doppio, to whom Diavolo orders to look at the landmark on the beach, as the traitors have a too determined look on them to have been truly defeated.
