Nobody talks about this one. A black cat detective and a missing pair of shoes sounds disposable until you realize the show treats the mystery like it matters, like every detail, the shoe shape, why Hanako cares, what Felix notices first, is worth your full attention. It moves slow. It breathes. By the end you've watched a small, perfect thing that knew exactly what it was and didn't waste a second pretending to be bigger.

Felix is a black cat who works as a detective. When someone steals Hanako's shoes, he gets moving and sets out to track them down. The film is a mystery built around that one case, following the feline sleuth as he searches for the missing pair.
