Crazy Diamond Is Unbreakable (story arc)

The Invincible Crazy D (クレイジー・は砕けない) is the twenty-eighth and final story arc in Part IV: Diamond Is Unbreakable.

Summary
Kira proves to be a difficult adversary, as he combines Stray Cat's aerokinesis with Killer Queen's explosive charges to produce invisible air bombs. After defeating Okuyasu, Kira charges Okuyasu's body to explode on contact, forcing Josuke into a dilemma over whether to take a chance at healing Okuyasu or to pummel Kira. Hayato, however, jumps in the way and sets off Okuyasu's bomb himself, after which Josuke pieces the two back together with Crazy Diamond and resumes his fight with Kira.

Despite the impediment, Kira refuses to back down and his air bombs retain their accuracy even after Josuke attempts to escape them. Hayato eventually finds out that Yoshihiro had been hiding in his jacket pocket and had been giving instructions to his son and Josuke deprives Kira of his means to attack them accurately by faking the radio call and directing an air bomb to incinerate Yoshihiro's photograph. Without the accurate means to incinerate Josuke any further, and with Josuke's blood still on his shirt, Kira is defeated when glass shards stained with Josuke's blood strike him via Crazy Diamond's restoration abilities.

Kira, unwilling to accept defeat, is pummeled out into the neighborhood side-walk, exposed to the crowd of people he did not want to get noticed by. Unwilling to accept this irony, Kira attempts to use Bites the Dust again and escape. Gloating over how he won and is now hidden again he gets confused when he sees he's in an alleyway that isn't anyway near where he works, and when he looks at his watch he sees its still broken after getting hit by Stray Cat when Hayato took him in his bag.
