Our protagonist is Madara, a young apprentice blacksmith that roams the world along with his grandfather Tatara, offering their services as makers of mechanical limbs. Madara's fate, however, changes when the village they are staying in is invaded by the Mouki, demons sent from the evil Emperor Miroku. After witnessing the death of his grandfather, Madara learns that his own mechanical body contains an immense power of mysterious origins, which he uses to defeat the fiends. Now set out on a mystic quest to end the threat of Miroku once for all, and accompanied by his female friend Kirin and the rebel princes Seishinja and Chaos, Madara starts a journey into the unknown world to face challenges beyond his imagination.
The franchise is best known outside Japan for its varied videogames. The manga being originally published in a videogame magazine also helped.
This work provides examples of:
- Body Horror: The varied demons, particularly in the anime, as you can't have an early nineties OVA without tentacled monsters.
- Cyborg: Madara himself has artificial limbs. Cyborgization seems to be incredibly common in the setting despite its Medieval Stasis.
- Shout-Out: Madara's character arc is essentially a giant reference to Hyakkimaru from Osamu Tezuka's Dororo.
