Josuke Higashikata is a high school student with a heart as large as his signature pompadour, but his quiet life in the seaside town of Morioh is shattered when he meets a mysterious visitor named Jotaro Kujo. Also known by its original Japanese title *JoJo no Kimyō na Bōken Part 4: Daiyamondo wa Kudakenai* or the alternative translation *Diamond is not Crash* this vibrant chapter of the legendary Joestar saga begins with the shocking revelation that Josuke is the illegitimate son of Joseph Joestar. Gifted with a supernatural power known as a Stand, Josuke finds himself thrust into a world of bizarre phenomena as an ancient Bow and Arrow begin to awaken dangerous abilities in the town’s eccentric residents. He must quickly learn to master his powers to defend his home, struggling to reconcile his newfound family legacy with the simple desire to keep his friends safe in an increasingly strange world.

The stakes of this supernatural mystery skyrocket when a chilling truth emerges: a cold-blooded serial killer has been stalking Morioh’s residents in secret for nearly twenty years. This terrifying discovery turns the town’s sunny facade into a labyrinth of danger, where a monster hides behind the mask of an ordinary neighbor. Forced to confront an enemy who thrives on anonymity and possesses a lethal explosive power, Josuke and a band of unlikely allies embark on a desperate investigation to unmask the predator before he can strike again. Driven by an unwavering sense of justice and a deep-seated love for his community, Josuke pursues a singular, heroic goal: to purge the evil poisoning his streets and ensure that the peace of his beloved Morioh remains truly unbreakable.
