After apparently failing Polpo's test, Giorno is attacked by his stand, Black Sabbath, who tries to pierce his soul with a stand arrow.

Bucciarati and Abbacchio are the only members of the gang left in the yacht. They have to find out where the enemy stand is hiding and how does it work.

After defeating Zucchero, the gang realizes that he has already told someone else where they were going and why.

The Stand that attacked Narancia was named Crush and belonged to Squallo, a member of the boss's elite guard. On top of that, Narancia suddenly can only say the exact opposite of what he's thinking, thanks to the ability of Talking Mouth, the Stand of Squallo's partner, Tiziano. Using Narancia, Squallo and Tiziano throw the team into chaos. The two elite guard members put Narancia in danger, but he boldly faces them so they can get out of Venice safely.
