Description
Louise Françoise Le Blanc de La Vallière is the third daughter of Duke Sandorion de La Vallière and Karin de La Vallière, nobles ruling Tristain's northeastern territory. She frequently clashes with her eldest sister, Éléonore, yet remains deeply attached to her second sister, Cattleya. Her childhood friendship with Princess Henrietta leads Henrietta, upon becoming Queen of Tristain, to adopt Louise as her sister, positioning Louise as heir presumptive and second in line for the throne.
Enrolled as a second-year student at the Tristain Academy of Magic, Louise consistently fails to cast elemental spells, resulting in explosive outcomes that earn her the mocking nickname "Louise the Zero" from peers and staff. This failure masks her true heritage as a Void mage, a rare and potent hereditary magic linked to Halkeginia's founder, Brimir. During the Familiar Summoning Ritual, she unexpectedly summons Saito Hiraga, a human from Japan, binding him as her familiar with a sealing kiss that brands him with Gandálfr runes. Initially treating Saito as a servile animal, forcing him into menial tasks and sleeping on straw, their relationship evolves from hostility to mutual affection. Louise often reacts with jealousy to Saito's interactions with other women, frequently punishing him physically with a whip or magical explosions.
Her Void magic manifests through powerful spells like Explosion, causing massive destruction; Dispel, nullifying other magic; Illusion; Teleport; and World Door, enabling interdimensional travel. These abilities emerge during critical moments, repelling Albion’s invasion of Tristain and combating an Ancient Dragon. Her Void lineage thrusts her into conflicts, culminating in her renouncing her aristocratic status to rescue her classmate Tabitha from Gallian imprisonment. After this mission, she rejoins the Tristain court as crown princess.
Later, Louise temporarily erases her memories of Saito to prevent perceived "corruption," though he restores them by sharing his own memories. She serves as a priestess alongside Tiffania for the Pope’s anniversary enthronement and participates in battles against Gallian forces and the Ancient Dragon. Following the dragon's defeat, Louise and Saito marry. After the wedding, she uses World Door to travel with him to Japan, meeting his parents.
Louise possesses a petite stature, standing 153–156 cm tall, with long pink hair and pink eyes. She typically wears the Tristain Academy uniform: a white blouse, gray pleated skirt, thigh-high black stockings, Mary Jane shoes, and a black cloak fastened with the school’s emblem. Her personality blends aristocratic pride, stubbornness, and impulsiveness with underlying vulnerability, loyalty, and self-sacrifice. She exhibits tsundere traits—harshness masking deep affection—especially towards Saito. Her relationships include her rival, Kirche von Zerbst, whose provocations fuel Louise’s competitive streak, and Tabitha, whom she supports unwaveringly. The character is named after Louise de La Vallière, a 17th-century French noblewoman and mistress of Louis XIV.
