A student of Ena dai gu Fillmore, Nio Hathler is the 4th Fillmore headdliner chosen as an ace Arcanna Knight. Though young, her pedigree and training more than make up for her lack of experience. Thus she was chosen as the Knight of Clubs and given charge of an Arcanna Siren. Her co-pilot is Koop Fatima Stoy.
Nio is a serious, straight-laced sort of person.
