She can shoot anything without missing her target within 2km radius. Her personal weapon is a Dragunov sniper rifle.

Jeanne d'Arc

Jeanne d'Arc 30th (also known as Durandal or Diamond Dust Witch) is an ice ability user from EU (criminal organization). During the events in Volume 2 of light novel, she is targeting Shirayuki in an attempt to kidnap her and force her to join EU. She is successfully captured with the combined efforts of Aria, Kinji and Shirayuki during the season of Adseard. As one of the conditions of Plea Bargain, she was forced to stay in Butei High as a 2nd year international student from Paris enrolled in Informa department. As a reliable Informa student, Kinji most of the time, asks for her aid whenever he needs a supply of knowledge about a particular case he is involved at. Jeanne and Riko get along with each other very well.
     She is one of the few people that knows Kinji's secret. Her personality is serious and cool. Her first comment about Butei High's skirt is: "Unmarried girls shouldn't openly reveal their legs like this!". However, that notion was pretty much shattered because of Riko's strong influence on her, and she had grown a habit of secretly collecting maid dresses, lolita fashion or any other cute dresses.
