In a world of constant war between humans and witches, there exist the beastfallen—cursed humans born with the appearance and strength of an animal. Their physical prowess and bestial nature cause them to be feared and shunned by both humans and witches. As a result, many beastfallen become sellswords, making their living through hunting witches. Despite the enmity between the races, a lighthearted witch named Zero enlists a beastfallen whom she refers to as Mercenary to act as her protector. He travels with Zero and Albus, a young magician, on their search for the Grimoire of Zero: a powerful spell book that could be extremely dangerous in the wrong hands. During their journey, his inner kindness is revealed as he starts to show compassion and sympathy towards humans and witches alike, and the unlikely companions grow together.

Louise Françoise Le Blanc de La Vallière is a self-absorbed mage in a world of wands, cloaks, and royalty. Although she studies at Tristain Academy, a prestigious school for magicians, she has a major problem: Louise is unable to cast magic properly, earning her the nickname of Louise the Zero from her classmates. When the first year students are required to perform a summoning ritual, Louise's summoning results in a catastrophic explosion! Everyone deems this to be yet another failure, but when the smoke clears, a boy named Saito Hiraga appears. Now Louise's familiar, Saito is treated as a slave, forced to clean her clothes and eat off the ground. But when an unfamiliar brand is found etched on Saito's hand from the summoning ritual, it is believed to be the mark of a powerful familiar named Gandalfr. Wild, adventurous, and explosive, Zero no Tsukaima follows Saito as he comes to terms with his new life and as Louise proves that there is more to her than her nickname suggests.

Revered as heroes for their role in defending Tristain, Louise Françoise and her familiar Saito Hiraga face heavy pressure to continue protecting the Kingdom. With an uneasy peace now established within Albion, the newly crowned Queen Henrietta must deal with a political struggle brewing on the horizon. To make matters worse, a new villain has begun plotting in the shadows against the Crown. With the continuing threats that face the Kingdom, Louise and Saito are compelled to work together once more. No longer Louise the Zero, the young mage's newfound aptitude for Void magic gives her enough power to wipe out an entire village; however, wielding these abilities comes with its share of challenges. As more conflicts arise, the idea of placing honor above oneself is put into question—regardless of their answer, their only choice is to see it through until the end.
