The animation catches light in ways modern digital can't replicate, every frame feels hand-drawn because it is, and the soundtrack knows exactly when to let silence do the work. A female ninja protagonist who moves through 1580s Japan with agency instead of as a reward, caught between the machinery of war and her own survival instincts. The action sequences stumble more than they soar, but the supernatural darkness underneath keeps pulling you back, this is a film that knows its horror lives in what the blade cannot cut.

In 1580, the armies of Lord Oda Nobunaga are spreading across Japan. Ayame, the last of the Kasumi clan, barely escapes the massacre of her people and slips away into hiding. The dagger she carries is one of three mystical blades. She teams up with Sakon and Ryoma, rogue ninja who hold the other two weapons, a sacred sword and a spear. An old prophecy tells of a comet, a dark god rising from deep in the earth, and three blades joining as one to defeat evil. To fulfill it, the three warriors must combine their weapons and skills or die in the attempt. This action film is an edited version of the earlier OVA.
