Isabelle du Monceau de Bergendal is a Witch of the 506th Joint Fighter Wing. Isabelle is a small aristocrat from Belgica. When the country fell, she and her family emigrated to Britannia.
Isabelle, who goes by "Isaac" amongst friends, is calm, collected, and has a silver tongue, doing things mainly for her own amusement. This usually includes cracking jokes from old books she's read or playing pranks on the other members of the 506th's A-unit.

"Noblesse Oblige" - The obligation of nobles. This addition to the World Witches franchise focuses on the 506th Joint Fighter Wing; a squadron of witches tasked with protecting innocent people from the Neuroi following the liberation of Gallia. These Witches are referred to as the "Noble Witches" because of their social status and their dedication to serving the needs of the less fortunate.
