Shining D (Diamond) is Unbreakable, Part 1 (Episode)

Crazy Diamond Is Unbreakable, Part 1 (クレイジー・は砕けない その1) is the thirty-seventh episode of Diamond is Unbreakable and the one hundred eleventh episode of the JoJo's Bizarre Adventure anime. It covers Chapter 426 through Chapter 430.

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.

Manga/Anime Differences

 * Added a flashback to Hayato calling Josuke in the house before leaving.
 * Removed Kira's detailed mathematical calculations to predict where the air bombs would travel.

Commentary
"This is where the ultimate fight begins. Between Bites the Dust’s cancellation, Okuyasu being wounded, and Josuke and Kira's face-to-face, the episode is just full of twists. I remember feeling very motivated when looking over the storyboard.

In regards to the breaking heart visualization that shows when Bites the Dust is deactivated, I took a bit of inspiration from the second opening, specifically when the hand squeezes the heart until it explodes. I loved this scene and wanted to use it again in the series. Mission accomplished, the circle is now complete.

When we discover Stray Cat in the belly of Killer Queen, the colors veer into mostly red tones to symbolize anger. Regarding Stray Cat, his attack where it launches an air bubble was achieved by displacing the layer and inflating it to show how it approached its target. Had it been required to draw this by hand, it would have taken significantly more drawings. This is especially bad since the drawings were getting more and more detailed now. This is proof that our animators are 100% invested in the series. I should perhaps use them as an example for the character profile art. (laughs)"
