Ozon Baby's Pressure (story arc)

​​ is the seventeenth story arc of JoJolion.

Summary
It is morning at the Higashikata household. After witnessing a scene during breakfast, Jobin disables the camera and reminisces the first when he met the Rokakaka Smuggling Organization. During an argument with his father at the local baseball stadium, Jobin, wanting to rise in the social ladder, proposed to expand the family business, but Norisuke refused to his frustration. It was at this moment that Yotsuyu Yagiyama first contacted him.

In the present, Jobin buries Ozon Baby in the orchard. At the same time, Josuke and Rai sneak into the orchard through secret underground tunnels. Rai spots the Rokakaka branches, and plants several moth larvae inside it to have a fruit in two days.

Meanwhile, Jobin is confronted by Tsurugi in the garage, the latter asking about Jobin's actions. Before the conversation is concluded, Ozon Baby begins to attack the household, and gravely injures Tsurugi. Jobin realizes that Ozon Baby is an automatic Stand which will indiscrimately attack anyone in its range. Managing to bring Tsurugi back to safety, he also roughly grasps the enemy's ability: Ozon Baby can decrease the air pressure in a zone, but any closed space will dampen its effects. Cornered, Jobin revives Tsurugi and formulates his own plan, planning to use Josuke and Rai whom he is sure are in the garden. For their part, the two begin to feel the enemy's power in the tunnel but decide to go out in the open.
