Nobody talks about this one. An old man and his dog walk through a neighborhood, both scowling so hard that children cross the street to avoid them, but the score moves like breath, like time itself softening around their routine. There's no plot to chase, no conflict to resolve. What hits is the quiet recognition that scariness and loneliness look the same from the outside. By the end you're not afraid of the old man anymore. You're wondering who's afraid of him.
An old man with a permanently angry look takes his dog out for walks, and the dog wears the same sour expression as its owner. Together the pair look so fierce that the local children run off whenever they come near. The story is told in a single episode of music anime, built around this grumpy-looking duo.
