Jotaro Kujo! Meets Josuke Higashikata (空条承太郎！東方仗助に会う Kūjō Jōtarō! Higashikata Jōsuke ni Au) is the first story arc in Diamond is Unbreakable.
The year is 1999, ten years after the defeat of DIO in Egypt and we are introduced to Koichi Hirose who lives in Morioh, Japan. Koichi meets Jotaro Kujo, who is looking for a person called Josuke Higashikata.
Jotaro finds a Stand user with the Stand, Crazy Diamond, getting infuriated when his hair is insulted. Jotaro tells Josuke that his father is Joseph Joestar and that Josuke will get 1/3 of his inheritance when Joseph passes away. Jotaro also tells Josuke to beware of a man lurking around in Morioh that Joseph discovered with Hermit Purple.
A man sees a pretty woman walking in the street and invites her for a ride. She subsequently beats him up. The man asks a police officer to help him but he says that woman is his daughter, Tomoko Higashikata (Josuke's mother). Josuke and Koichi go to a store where a man is threatening to kill a woman. When he insults Josuke's hair, Josuke attacks him and the woman but heals the woman with his Stand's power. The man was revealed to be possessed by a Stand that was depicted in the photograph Joseph created.
