Ghost Hunt

Mid-ghost-story, high school freshman Mai Taniyama gets interrupted by a cold, sharply-dressed teenager named Kazuya Shibuya, and discovers he actually investigates the supernatural for a living. Through a series of clumsy mistakes involving broken equipment and an injured assistant, Mai ends up working for his paranormal research company. She calls him 'Naru' almost immediately, because he is genuinely insufferable in the most entertaining way possible. What makes Ghost Hunt work is that it takes the ghost-hunting premise seriously. Cases are multi-episode arcs, the investigations use real methodology, and the team that assembles around Naru includes a monk, a shrine maiden, a Catholic priest, and a spirit medium — all with different approaches and different beliefs about what they're dealing with. It creates this genuinely tense procedural atmosphere where you're never quite sure what kind of supernatural entity you're up against or how it's going to be resolved. The tone is dark and slow-burn. Don't go in expecting jump scares every five minutes — this is more creeping dread, strange children, and rooms that feel wrong. Think closer to Shinrei Tantei Yakumo or early Shiki than anything action-heavy. If you've bounced off horror anime that felt cheap or rushed, this one takes its time building atmosphere. It's 25 episodes adapted from a manga, and the case-based structure means it's easy to get pulled through one more arc before you realize how late it is.
