Mendosa, the chief adviser of the king of Valiante, begins a campaign to hunt down "witches," resulting in the deaths of many magical knights and their sorcerer assistants. Anna, a sorceress married to the knight Herman Lewis, gives birth to a son before her execution. Herman takes their child, Leon, and flees, raising him to be the heir of the legendary Golden Armor. By the time Leon grows up, Valiante is completely in the control of Mendosa, who drives out Prince Alfonso and his mother. Alphonso decides to seek out the man who inherited the Golden Armor to reclaim the throne and save his people.
