Dunbine is set in Byston Well, a parallel world that resembles the countryside of medieval Europe with kingdoms ruled by monarchs in castles, armies of unicorn-riding cavalry armed with swords and crossbows, and little winged creatures called Ferario, flying about offering help or hindrance depending on their mood. The main draw to the series were the insect-like Aura Battlers, used by the population of Byston Well to fight their wars. These fighting suits are powered by a powerful energy called “aura” or “life energy.” Certain people are strong enough with the aura-energy to act as power-supply to these mecha, making them Aura Warriors.
The series aired on Nagoya TV from February 5, 1983 to January 21, 1984, totaling for 49 episodes. There was a three episode animeOVA sequel, New Story of Aura Battler Dunbine (also known as The Tale of Neo Byston Well) released in 1988.
The series was later dubbed by ADV Films and was released to DVD in North America, along with the original Japanese version in 2003. However, it quickly became out of print, and as of 2017, is only now available as a digital purchase from Daisuki.
