The real weight hits when you realize you're watching a ninja fight his best friend's corpse, and the show treats that as horror, not spectacle. The animation moves like something alive and dying at once, all gothic ink and rotting detail that makes every frame feel like a violation. Two episodes is barely enough to contain what this demands, but that's exactly why it stays with you.

Warfare has left the land scarred and soaked in blood, and from that carnage the Yoma return. These demons from hell rise again, strengthened by the blood of countless dead warriors, and turn their violence on humanity. A skilled ninja sets out to stop the slaughter before it spreads further. But his mission carries a weight that cuts deeper than duty. His best friend, a fellow ninja, was killed in battle. Now that friend returns, raised from death to serve the very demons the ninja has sworn to stop. To end the Yoma's bloodshed, the ninja must face the undead comrade he once fought beside, in a two-episode supernatural horror action OVA.
