Crazy Diamond is Unbreakable, Part 4 (クレイジー・は砕けない　その④), originally in the WSJ release, is the one hundred sixty-sixth chapter of Diamond is Unbreakable and the four hundred thirty-first chapter of the JoJo's Bizarre Adventure manga.

Summary
Kira calls his boss, informing him that he'll be late for work under the guise of punishing his child. In reality, Kira begins to hunt through the neighborhood for Josuke, Okuyasu, and Hayato. He laments that with Josuke indoors, it'll be harder to target him with Killer Queen's air bombs. Kira is then stopped by a neighbor, believing Kira is spying on his neighbor. Kira ignores the man, who proceeds to steal Rio's underwear after he leaves. Unknown to him, Kira primed the underwear causing it to explode and kill the man, eliminating a potential witness to his battle with Josuke.

Hayato attempts to call Rohan for help, but Kira has already cut the phone lines. Josuke accepts Okuyasu's death and tells Hayato that his Crazy Diamond will be the one to kill Kira. Knowing that Kira is getting desperate, he tells Hayato to hide and waits for Kira to attack through the front door. Unknown to Josuke, Kira sends an air bomb through the window which Hayato spots. He warns Josuke about it as the two wonder how Kira knows their exact location.
