Jeanne d'Arc  

Diamond Dust Witch, Durandal, ジャンヌ・ダルク

Jeanne dArc 30th, also known as Durandal or Diamond Dust Witch, is an ice ability user from a criminal organization called EU. In Volume 2 of the light novel, she attempts to kidnap Shirayuki and force her to join EU. She is successfully captured by Aria, Kinji, and Shirayuki during the season of Adseard. As part of her plea bargain, Jeanne was required to stay at Butei High as a 2nd year international student from Paris enrolled in the Informa department. Jeanne is known for being a reliable Informa student who assists Kinji with information about cases he's involved in. She gets along well with Riko and is one of the few people who knows about Kinji's secret. Jeanne has a serious and cool personality, but she was initially opposed to Butei High's skirt policy, stating that unmarried girls shouldn't reveal their legs so openly. However, her views on this have been influenced by Riko, and she now collects maid dresses, Lolita fashion, and other cute outfits. While Jeanne is exceptional in terms of fighting skills, beauty, and ability, her drawing skills are not impressive. Despite her strength, she claims to be the weakest among EU members.
