Description
Louise Françoise Le Blanc de La Vallière, a noble mage from Tristain’s esteemed Vallière family, is the third daughter of Duke Sandorion and Karin de la Vallière. Raised in an illustrious household alongside her sisters, Éléonore and Cattleya, she shares a particularly close bond with the latter. Persistent comparisons to her siblings and familial pressures cultivated insecurities around her magical ineptitude, earning her the mocking epithet "Louise the Zero" from peers at Tristain Academy of Magic due to her repeated spellcasting failures.

Her trajectory shifted during the Familiar Summoning Ritual, where she unexpectedly summoned Saito Hiraga, a human from another world, as her familiar. Their relationship, initially fraught with tension, gradually deepened into mutual reliance and romance. Saito’s role as her Gandálfr familiar linked his combat prowess to her latent Void magic through ancient runes. Though fiercely loyal, Louise’s pride and jealousy frequently sparked conflicts, especially with rivals like Kirche von Zerbst or Tiffania Westwood vying for Saito’s attention.

Louise’s true magical affinity emerged as Void magic—a rare legacy tied to Founder Brimir—granting her spells like Explosion, Dispel, World Door, and Teleport. Mastering these abilities demanded rigorous effort, but their revelation elevated her status. Adopted by Queen Henrietta, she became heir presumptive and Crown Princess, tasked with defending Tristain against threats such as King Joseph of Gallia and his agent Sheffield.

Petite in stature, Louise stands out with long pink hair, matching eyes, and a modest bust contrasting her peers’ more pronounced figures. She dons Tristain Academy’s uniform: a white blouse, gray pleated skirt, black thigh-high stockings, and a signature black cloak. Her demeanor balances aristocratic haughtiness with vulnerability, reflecting her struggle to validate her worth amid lingering self-doubt. Despite a fiery temper, she exhibits unwavering courage, risking her life in battles to protect allies and loved ones.

Her journey intertwines reconciling her Void heritage with noble lineage, confronting challenges like Saito’s fading Gandálfr runes in *Rondo of Princesses*, which they overcome through renewed trust. Alliances with figures like Tiffania, a half-elf Void mage, showcase her growth in transcending jealousy to unite against shared foes. By the series’ end, she marries Saito, adopting the name Louise Françoise le Blanc de Hiraga de Ornielle—a testament to her evolution from an insecure student to a resolute leader and devoted partner.
