Summary
As Kira brags about his victory to Hayato, he unknowingly reveals his own identity to Josuke, who Hayato had secretly called ahead of time. Needing Killer Queen to protect himself from Josuke, Kira is forced to undo Bites the Dust before it is able to kill Rohan, preventing his death. Forced to Engage in a battle against Josuke and Okuyasu, Kira manages to retrieve Stray Cat and use its air shots to create invisible remote bombs, lethally wounding Okuyasu.

As Josuke tries to reach Okuyasu in order to heal him, Hayato deduces that Okuyasu's body might have been turned into a bomb, leaving Josuke with the tough decision of whether to sacrifice himself to save Okuyasu. However, Hayato, also deducing that Kira can only set off one bomb at a time, sets off the bomb on himself, allowing Josuke to heal both him and Okuyasu. As Kira launches another air bomb, Josuke, refusing to believe Okuyasu might already be dead, manages to use Crazy Diamond on debris in his wounds to dodge the explosion.

Josuke and Hayato soon retreat into an empty house, carrying Okuyasu's body with him as the rain stops. Kira, meanwhile now no longer believes that Jotaro isn't the greatest threat to his peaceful life, but Josuke is.
