Joutarou Kuujou

Joutarou Kuujou is a Japanese student and marine explorer recognizable by his signature torn hat and a long blue uniform jacket decorated with yellow chains. He originally believed his Stand was an evil spirit, leading him to turn himself in to the police. Once he understood its true nature, he learned to master Star Platinum, an Aztec-inspired entity capable of machine-like precision and devastating physical strikes. While often driven by a quick temper, Joutarou utilizes high intelligence to balance brute force with strategic combat. During the events of Part 3, Dio identifies him as his primary threat. By the time of Stone Ocean, Joutarou has transitioned into an oceanographer living in the US, where he is married and raising his daughter, Jolyne, who has inherited his Stand potential.
