Nobody talks about this one. A single, perfect hour that moves like a folk tale being told by someone who knows exactly when to pause. The mystery unfolds not through exposition but through what the camera chooses to show you, what it chooses to hide, and the weight of silence between frames. Okamoto's direction trusts you completely. You walk out of it having understood something you can't quite explain, the way you understand a dream after waking.
