The year is 1999. Ten years have passed since DIO’s death, but his presence sticks with many of his former followers - including Hol Horse, a mercenary-turned-freelancer.
Operating from Egypt, Hol Horse is asked by an elderly woman to find her lost parrot - it was trained by the previous owner of Pet Shop, and therefore may also have a stand. After consulting with Boingo, his reluctant partner with the prophetic book Thoth, he discovers the location that the parrot went so he can track it down.
But Hol Horse is confused. Why would a parrot fly all the way to the small Japanese town of Morioh?
