Hamaji steps into Edo expecting to hunt monsters, instead she finds the Fuse are just trying to survive in a city that wants them dead, and suddenly the hunt becomes a mirror she can't look away from. The animation doesn't just show you period Japan, it breathes it, every street and shadow rendered with enough care that you feel Hamaji's isolation the moment she realizes her target is human. The romance between Hamaji and the Fuse girl never quite lands because the film knows what matters: watching someone choose compassion over the life everyone expects her to live.

After her grandfather dies, Hamaji lives alone on a remote mountain, hunting to survive. A letter from her brother, a would-be samurai, draws her to Edo, where the severed heads of six dogs greet her. They belong to the Fuse, eight beings that are part human and part dog, blamed for killing people across the city. Her brother asks her to help track down the last two and claim the shogunate's reward. The task is harder than it sounds, because the Fuse pass easily as human, and a kind stranger Hamaji helped escape attackers shows the signs of being one. When she unexpectedly becomes friends with one of the Fuse, she is pulled between her solitary life as a hunter and the young woman that friendship helps her discover. The film is a supernatural action drama set in Edo.
