When Conan Edogawa observes that every victim shares a connection with the now-renowned detective Kogorou Mouri, suspicion immediately shifts toward the newly freed offender Jou Murakami, as Kogorou was responsible for his capture a decade earlier. With additional targets still in danger, Conan and law enforcement are resolute in apprehending the perpetrator. As the investigation progresses, both Conan and his companion Ran Mouri uncover deeper insights into her parents' split and the events that unfolded ten years prior, and the lingering unresolved mysteries.
