ゼロの使い魔
Due to the sacredness of the ritual, Louise reluctantly accepts Saito as her familiar, but proceeds to treat Saito as any other familiar, only worse: making him wash her clothes, sleep on a bed of hay, and whipping him with a riding crop whenever he upsets her. "The Familiar of Zero" follows the adventures of Louise and Saito as they help their classmates and friends, while occasionally blundering into situations where they risk their lives to save one another and Tristain. Saito tries to find a way to get back to Japan, but he also gains a mysterious power that allows him to wield swords and other weapons to perform heroic feats. They also eventually learn the truth behind Louise's magic inabilities. As Saito's and Louise's friendship grows and they start to work together, they ultimately fall in love with each other.
