JJL Chapter 69

Rock Human and Rock Animal, Part 2 (岩人間と岩動物 その②) is the nine hundred sixteenth chapter of the JoJo's Bizarre Adventure manga. It is also the sixty-ninth chapter of JoJolion.

Summary
The mechanism of Brain Storm is explained. The crystal-like Stands grab onto the skin with hidden feelers, then dig inside the body and then the blood stream to cause hemolysis, multiplying exponentially and boring gaping holes in the body.

Urban Guerrilla gloats, as his target Rai Mamezuku is in a desperate position and already Brain Storm is digging into Rai's body, while Josuke and Yasuho are cornered by Doremifasolati Do. As Urban threatens to turn Rai into a shoe lace, Yasuho despairs on her boulder. Although she begins to blame herself, Josuke interrupts her, stating that their predicament is simply due to the difference in offensive power between them and the Rock Humans.

Meanwhile, Rai starts to rant about the impending doom of humankind. In his mind, although the Rokakaka is a miraculous cure or a source of income for mere humans, the Rock folk have been using the fruit for a considerably longer time and it is tailor-made for them; in the contrary, humans and Rokakaka have poor compatibility due to differences between carbon-based life and silicon-based life. Beyond the limited use the Higashikata Family and by extension humans have for the new variety, the new Rokakaka, Urban claims, will allow them to shift the hierarchy between humankind and the Rock men.

Unfazed by either his wounds and Urban's speech, Rai unravels his arm and transforms it into a slingshot with which he shoots a fork toward Urban, hitting him above the eye and shattering his goggles. Urban cries out in pain and orders Brain Storm to increase its damage, but Rai already prepares a second fork. Despite the countless holes on his body, Rai manages to shoot his fork but unfortunately misses, the fork landing on the pole instead. The plant appraiser subsequently falls to the ground. Victorious, Urban descends the pole and already shouts menacingly at Josuke.

For his part, Josuke looks at Rai, and seeing the determination in the eye of the plant appraiser, is impressed and understands why Norisuke considers him a valuable ally. Despite Yasuho's pleas, Josuke jumps to the ground, intending to take down Urban at the risk of being badly hurt. Josuke runs to the base of the seventh pole under Urban's unimpressed gaze and pursued by Doremifasolati Do who is already grazing his feet. Ominously stating that careless humans will end up forever below the rocks, Urban challenges Josuke. The Rock Human then jumps down to the ground, deploying Brain Storm to bore into the soil so he can find himself underground immediately and enter his partner's shell before Josuke can reach him. Josuke begins to sink into the ground, as Yasuho panics and Rai attentively watches.
