Kirche

Kirche is a Fire mage, as her secondary names are "Kirche the Ardent" and supposedly, after Saito wins against Guiche, "Kirche the Passion". It is often implied in the anime that she has a habit of choosing (and sleeping with) her boyfriends with a fixed schedule, however, when she meets Saito, her habit could've possibly changed because of him.

Her best friend is Tabitha, and is always sticking with her through thick and thin, but this might be attributed only to Tabitha's fondness and closeness for action and adventure. She cares for Tabitha a lot, and sometimes, would even get mad if anyone would hurt the latter, as shown when she learns of Tabitha's secret during their visit to Gallia.

Kirche is the daughter of a Germanian military family; However, she was a nuisance to the family since she was expelled from her last school and was forced to marry an "old geezer" (by her words). She later got transferred to the Academy and met Tabitha.

Kirche has a special talent in persuasion, as she does not think twice of using her body to gather secret information like in Gallia when they tried to gather information on Tabitha's whereabouts. A very small amount of men could resist this persistence, which does not include the Academy boys including Saito himself, until he realizes his feelings for Louise.

This talent is something Kirche often uses to annoy Louise, who has been her bitter rival ever since, until she admits he knowledge of Louise's void affinity and apologizing for the terrible things she had done to Louise, though she side comments that if Louise was not a Noble, she would make a decent maid back in their family's mansion.

Kirche's love interests include most of the Academy boys, Saito, and finally, Professor Colbert.
