Aura Battler Dunbine

Shou Zama, an 18-year-old from Tokyo, is transported to Byston Well, a medieval fantasy world where he joins Lord Drake Luft's forces. People from "Upper Earth" like Shou possess strong aura power, which allows them to pilot the insectoid mecha, Aura Battlers, designed by Shot Weapon. Shou's allegiance shifts after meeting Marvel Frozen, who is rebelling against Drake's ambitions, and he joins the resistance led by Neal Given. Shou and his comrades, including Riml, the daughter of Drake, work together to prevent Drake's takeover of Byston Well.
