This one doesn't chase you, it settles on you. A single 1992 OVA, no franchise, no sequel hook, just Goro working a missing husband case in a smoke-colored 70s-80s Japan scored with jazz, and the deeper he digs the less clean the moral ground gets. The twist isn't a gotcha, it's an ethical trapdoor, the kind that makes you sit with the credits arguing with yourself about who deserved what. Inspector Yamagishi is the reason people who've seen this won't shut up about it, a voice performance and character design that carry more weight than the runtime should allow. Yes, the setup can read sentimental if you're in a cynical mood, and yes, it's nearly impossible to find, which is exactly why finding it feels like being handed a secret. If Master Keaton's quiet competence and Kindaichi's moral knots are your lane, this is the fifty minutes nobody told you about.
Private investigator Goro takes on a routine missing persons case: a husband vanished without a trace, leaving behind only questions and a desperate wife. His search pulls him deeper into a twisted psychological maze where nothing adds up and every lead spirals into darker territory. One stormy night, a young woman is shot dead on a cliff, and the man last seen with her is now wanted. Working alongside a law enforcement officer who has his own reasons for tracking the missing husband, Goro follows a trail of tragedy and intrigue and runs into a deranged killer as he tries to find how the murders and the disappearance are connected.
