Crazy Diamond Is Unbreakable (story arc)

Crazy Diamond Is Unbreakable (クレイジー・は砕けない), also known as Crazy D (Diamond) Is Unbreakable, is the twenty-eighth and final story arc in Diamond is Unbreakable.

It narrates the climactic battle between Josuke Higashikata and Yoshikage Kira.

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. Josuke deprives Kira of his means to attack them accurately by faking a radio call to Kira, who directs 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 sidewalk. Kira attempts to use Bites the Dust again and escape.
