* AlternateCharacterInterpretation - The live action adaptation makes it seem more like Kindaichi is ObliviousToLove (at least in Miyuki's case) rather than just playing coy.
* MagnificentBastard - The Moriarty-esque recurring villain that matches wits with Kindaichi.
* NightmareFuel - Most cases with a supposedly "supernatural" culprit count. There are many of them. The live action "The Seven Mysteries of the School" ("Smoke and Mirrors" in the U.S. manga translation) case had a scene involving a science lab at night with a jar containing a human head that suddenly...''opened its eyes''.
