A half-ogre born with a sword for a hand hunts his own kind across feudal Japan, chasing the delusional hope that genocide will make him human. The OVA doesn't waste time on philosophy, it moves between villages and battlefields with the focused brutality of something made in 1994 that refuses to explain itself. Every swordfight is economical, every character encounter is a transaction, and the premise itself is the entire story. This is anime that trusts you to understand what it means to be a weapon pointed at your own bloodline. Four episodes. No filler. No redemption waiting at the end.
A half-ogre child enters the world gripping a legendary blade instead of inheriting horns. Nameless except for his weapon,the Onigirimaru, an ogre slayer,he walks between two worlds that will never fully claim him. His mother was ogre, his form human, but his purpose is singular and brutal: eradicate every ogre remaining in Japan. Driven by a dangerous belief that slaughtering his entire race might somehow transform him into something truly human, he becomes a solitary hunter. Each ogre he encounters brings him closer to either redemption or damnation, depending on whether his twisted logic holds any truth. The blade in his hand carries the weight of genocide, and he carries it willingly. This is a tale of blood and longing set against feudal Japan's shadowy places. Where yokai legends meet swordplay, where one warrior's crusade unfolds across episodic encounters with monsters both supernatural and tragic. It's violent, intimate storytelling that questions what price a person will pay to escape their own nature.
