I ran in on my own. Dior's bones come from the comic book JOJO's Wonderful Adventure: A Sea of Stones, which is the work of Hirohiko Araki. In the second film, Xu Lun took the initiative to enter the most severe isolation punishment room, because he learned that a magical bone ran here by itself, and this is Dior's bone. This work mainly tells the story of Kujo Jotaro's daughter, Jolyne Kujo, who was framed and arrested and imprisoned after "hit-and-run" with her boyfriend. In order to save his father, Xu Lun stayed in prison and fought against his enemies.
