Montmorency Margarita la Fère de Montmorency, a noble-born student at Tristain Academy of Magic, hones her skills in water magic while upholding her family’s ancient pact with the Spirit of Water—forged during a childhood pilgrimage to Lake Lagdorian with her father. Though her magical prowess remains modest, she summons Robin, an orange frog familiar, as a living emblem of her lineage’s bond with water spirits.

Her tempestuous romance with Guiche de Gramont oscillates between fiery confrontations and fragile truces, fueled by his chronic infidelity. A desperate bid to secure his loyalty drives her to craft a forbidden love potion—a scheme derailed when Louise inadvertently consumes it, triggering a perilous journey to the Spirit of Water’s domain. There, Montmorency negotiates using ancestral accords to procure a Spirit Tear, while Saito vows to retrieve the purloined Ring of Andvari.

Proud to her core, she bristles at diminutives like “Montmo” and engages in razor-edged rivalries with classmates. Though comporting herself with noble poise, jealousy sparks impulsive acts—publicly striking Guiche after his duplicity surfaces, or developing fleeting fascination with Julio Chesaré, a charismatic visiting cleric. Fate subjects her to absurd misadventures, including inhaling Siesta’s rogue love elixir, which triggers indiscriminate ardor until Tiffania Westwood’s memory magic erases the humiliating episode.

Her bond with Guiche matures into a dance of clashing wills and unspoken devotion, cycling through reconciliations and fresh betrayals. While she joins allies against existential threats, her personal saga orbits two gravitational centers—preserving her family’s mystical legacy and navigating love’s treacherous currents.
