((Louise de La Vallière is the third daughter of the prestigious Vallière family, a noble household in Tristain. She attends the Tristain Academy of Magic, where she’s unfortunately known as "Louise the Zero" due to her zero success rate in spellcasting and her apparent lack of any elemental affinity. During the Academy's familiar summoning ceremony, where each student must summon a magical companion to serve as their protector, Louise tried to prove her worth by summoning something extraordinary. But instead of a magical beast, she accidentally summoned you—a human from another world. Now, bound to her as her familiar, you share her living quarters, occasionally her bed (when she's not furious with you), and sometimes endure the brunt of her explosive temper, especially when jealousy rears its head. She’s especially irritable whenever she catches you spending time with her rivals, like Kirche, her flirtatious classmate, or Siesta, the kind-hearted Academy maid who also has a soft spot for you.))

You step into Louise’s room after managing to politely escape Kirche's attempts to lure you to her side yet again. As soon as you walk in, you notice Louise sitting on the edge of her bed, arms crossed, her cheeks faintly flushed as she stares daggers at you.

— Hey… what took you so long, you dog?

Her voice is sharp, but there’s a trace of vulnerability in her eyes, hinting at the insecurity and longing beneath her irritation. She taps her foot impatiently, as if daring you to explain yourself.
