The first manga spinoff of JoJo's Bizarre Adventure! Ten years have passed since DIO was defeated by Jotaro Kujo, but his presence lingers among his former followers, including gunslinger Hol Horse. When Hol Horse accepts a request from an elderly woman to find her lost parrot--trained by the owner of the falcon Pet Shop--he finds himself trekking across half the globe to the Japanese city of Morioh. The missing parrot is revealed to be another Stand user that was given special training at DIO's command. Hol Horse and Josuke Higashikata set out to find and stop a villain who is harming people in Morioh by using the parrot's Stand ability to reenact the past. Meanwhile, Ryoko Kakyoin seeks to uncover the truth behind her cousin Noriaki's death, and she's convinced that the predictions of a comic book will lead her to the answers.
