Jabarkan Agnès dari Daftar karakter The Familiar of Zero

is introduced in the second anime season as the Captain of the Tristain musketeers in service of Henrietta. She hates Mages, especially fire-element ones. She is fiercely loyal to Henrietta, who proclaims her one of the few people Henrietta can truly trust, and prefers to use a pistol or sword; she states that in combat, it is quicker than casting a spell. Originally very suspicious of Saito (particularly when she thought he was making a move on Henrietta), over time she comes to accept him as a trusted ally, even mourning his supposed death at the end of Season 2. One of her motives for joining Tristain's army is avenge her parents who died when her village, D'Angleterre, was razed, and she eventually tracks down the people responsible. Her sexual preference is questioned when Siesta speculates to Louise whether Agnès prefers girls; Louise unintentionally affirms it because Agnès had recently kissed Louise on the lips during a spying mission in an attempt to draw attention away from themselves. She kills Lishman, a politician who tricked the government into burning the village, and fights the former vice-captain of the army when he holds the academy girls hostage, but learns the leader of that army, Flame Snake, is the primary man responsible. She then learns Colbert is the Flame Snake but also the one who saved her life after noticing the burn scar on his back. After Colbert sacrifices himself in season 2 but returns in season 3, Agnès gives up thirsting for vengeance; she eventually tells Colbert he has to make amends 'one hundred times' over for each member of her village.

In the novels, Agnès was asked by Henrietta to find Saito after his battle with the Albion army. She found him in Tiffania's village, and discovered he had lost his Gandálfr powers. She then trains Saito in swordsmanship, with some success.
