Louise Françoise Le Blanc de La Vallière (Born 6th August) is the female protagonist of the series. Although Louise is in her second year at the Tristain Academy of Magic, her magic skills still need a lot of work. Because of this she lacks self confidence, and her classmates look down on her, calling her "Louise the Zero." During the ceremony when all second year students summon their familiars, instead of summing a normal familiar like the other students, Louise summons a human from another world, Saito Hiraga. At first Louise and Saito do not get along, but as the series progresses, Louise falls in love with him, and, eventually, him with her. Louise is quick to become jealous whenever Saito is around other girls and either blows him up with her magic or beats him.
