SO Chapter 30

There's Six of Us!, Part 5 (6人いる！ その⑤), originally in the WSJ release, is the thirtieth chapter of Stone Ocean and the six hundred twenty-fourth chapter of the JoJo's Bizarre Adventure manga.

Summary
Ermes suspects that the inmate with a nose bleed is the Stand user. The nose bleed girl claims that the tan inmate hit her, pointing at the blood on her hand. The tan girl states that she remembers Ermes mocking Loccobarocco when he formed the search team. The other inmates claim the same thing. Tired of getting nowhere, Jolyne punches the nosebleeder in the face, knocking her out.

Jolyne decides to knock all of them out, but is stopped by the inmate with a shaved head. All three inmates' eyes go black, and they consider aloud in unison that Whitesnake may want to steal Jolyne and Ermes's Stands before they die. Jolyne uses Stone Free to punch one of them out, but the prisoners begin melting into black sludge. The tan inmate is revealed to have been the impostor, its body created from the remains of the missing prisoners; the other two were killed and assimilated when they inspected the tractor. As the tan inmate melts, a similar Stand to the one seen earlier emerges, with two DISCs lodged in its head. The Stand, Foo Fighters, announces its mission: to preserve the existence that Whitesnake bestowed upon it, Foo Fighters will protect the Stand's collected DISCs at any cost.

Ermes suggests that they run into the field, away from the water. Jolyne, having figured out that the Stand is its own user, instead explains that they have to keep it away from water. Ermes claims that cannot be true, and that Foo Fighters is nothing more than a mass of plankton. Foo Fighters uses 's theories to explain how it has sentience; insulted by its enemies' confusion, the Stand runs toward the barn in order to hide the discs. At the same time, its other form in the water begins dragging the guard into the water, hoping to force the bracelets to explode.
