The year is 1999. Morioh, a normally quiet and peaceful town, has recently become a hotbed of strange activity. Jotaro Kujou, now a marine biologist, heads to the mysterious town to meet Josuke Higashikata. While the two may seem like strangers at first, Josuke is actually the illegitimate child of Jotaro's grandfather, Joseph Joestar. When they meet, Jotaro realizes that he may have more in common with Josuke than just a blood relation. Along with the mild-mannered Koichi Hirose and the boisterous Okuyasu Nijimura, the group dedicates themselves to investigating recent disappearances and other suspicious occurrences within Morioh. Aided by the power of Stands, the four men will encounter danger at every street corner, as it is up to them to unravel the town's secrets, before another occurs.
