Synopsis
A female ogre (oni) once gave birth to a child who looked human. Instead of having an ogre's horn, this infant came into the world holding a sword called "Onigirimaru" or Ogre Slayer. The child has no personal name and is known only by the name of that blade. Although his appearance is human, he is a pure ogre. Convinced that he will become human once all of his kind have vanished from the human world, he embarks on his destiny to eliminate every ogre. Even now, in the motherland of Japan, he continues to hunt down and slay ogres.
