Ep. 29: The team heads to Rome to find the Stand arrow while facing ambush by Cioccolata and Secco.

Bucciarati and Giorno fail to identify a suspect in police databases, but a laptop voice reveals the boss is Diavolo and suggests a Stand arrow in Rome is the only counter to King Crimson. The boss dispatches Cioccolata and Secco to intercept the group. As Guido and Narancia travel to Rome, the voice explains that arrows originate from a Greenland meteorite virus granting superhuman powers. Trusting this information, Bucciarati agrees to meet the voice’s source at the Colosseum. Upon reaching the Italian mainland, the team is attacked by Cioccolata and Secco. Cioccolata deploys his Stand, Green Day, to spread lethal mold. Giorno deduces the mold activates when victims lower their bodies, prompting Mista to detonate fuel tanks and launch the team onto the shore to escape the ambush.
