Ozon Baby's Pressure (story arc)
Ozon Baby's Pressure (オゾン・ベイビーの加圧 Ozon Beibī no Kaatsu) is the eighteenth story arc of JoJolion.
The Higashikata House is under attack from Ozon Baby which manipulates pressure, everyone save Jobin having fallen unconscious. Trapped in their shed, Jobin and the revived Tsurugi realize that Ozon Baby is an automatic Stand which will indiscriminately 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. Determined,they set the orchard on fire by using origamis and Speed King to spur their enemies into action.
Indeed, Poor Tom rushes into the orchard to retrieve the branch while Josuke and Mamezuku go out, protected by Soft & Wet's bubbles. They met just as Mamezuku takes the branch and a fight ensues. Poor Tom takes out Rai and seize the branch but is poisoned by a yew seed. Pursued by Josuke, Poor Tom is bluffed into cancelling the air pressure ability, but his supposed allies from the hospital have arrived.
Surprisingly, Poor Tom is killed by a mysterious ability shooting through his head. An unseen person seizes the branch and drives away before Josuke can do anything. However, it is revealed that Tsurugi used Paper Moon King into tricking everyone: an ordinary branch has been fought over while Jobin stole the real Locacaca branch. They hide the branch, grafted into a cactus. Meanwhile, the ambulance driver discovers the trick and guesses that the arsonist is the one who has the branch.
Finally, Josuke returns to Mamezuku, revealed to be alive and slowly reconstituting himself. Desperate, Josuke can only observe his total loss.
