Rating: ***
Warriors of the three clans of shadow ninja must unite their spirits and their mystical weapons in order to stop an evil tyrant from opening a gateway to the demon world. Dark, brooding, and bloody, the story finally starts to twist and get interesting in the last twenty minutes, with pretty satisfying results. The character design and overall animation is average, but the main ninja girl (Ayame) gets to parade around in a variety of attractive and well designed ninja outfits. A good serious-minded ninja flick with gross monsters, but not all that engaging.
