In a world where sorcery reigns supreme, bumbling witch-in-training Louise Francoise le Blanc de La Valliere is known by her classmates at the Tristain Academy of Magic as “Louise the Zero.” During an important coming-of-age ritual, when each student must summon a lifelong familiar, Louise proves herself klutz when she mistakenly conjures a teenage boy from Earth. Now, whether they like it or not, Louise and her unwilling servant, Saito, are bound to each other by the laws of magic for all eternity!
Louise and her spellcasting companions have been sent on a top secret mission to the Kingdom of Albion, where the royal family is besieged on all sides by rebelling nobles. They are accompanied by the dashing Viscount Wardes, who is not only captain of the Griffin Corps but is also Louise’s longtime fiancé. Saito can’t help but feel jealous of the impressive captain, but there’s a more pressing concern: will they find the Prince of Albion in time before the kingdom is lost?
Saito’s been in hot water with Louise before, but things have never looked this bad! Siesta, and the rest of the gang take Saito on a treasure hunt that could fix his romantic problems once and for all, but he finds more than he bargained for–the first real clue that could lead him back to his homeworld. Meanwhile, the small nation of Tristain is on the brink of war with the Albion Empire whose underhanded tactics threaten to push hostilities over the edge. Can a mage called Zero and her legendary familiar come together to prevent a catastrophe?
