Taking the standard murder mystery setup and flipping it on its head, Munou na Nana introduces you to the killer in the first scene and revolves its (early) mystery elements around wondering how she’ll get away with it. As it progresses and more is revealed about the protagonist the focus shifts to a broader conspiracy-minded framework without losing any momentum whatsoever.
I’m particularly fond of the ending, though most will probably be more pissed off about the show wrapping on an arc’s climax with no sign of a continuation in sight.
Also told from an antagonist’s point of view, though one more morally ambiguous than Nana‘s, Yuukoku no Moriarty tells the story of Sherlock Holmes through the lens of his greatest rival. It’s less a mystery series and more an almost episodic revenge drama, one populated by surprisingly likable characters and consistent thematic framing.
