The headmistress of the NY branch of the Magdalan Order. Though she appears to be older, she's only 29 years old. Her height is 168 cm and her weight is 50 kg. She is a first-class militia and is a rather strong and capable woman, but she frequently loses her patience with Rosette, who is a real source of trouble for her. Despite this, she sincerely cares about her and doesn’t stand the idea of Rosette wasting her life because of the contract she made. Due to her hatred of devils, Sister Kate is very distrustful of Chrno, but she knows how much he cares for Rosette, so she tries to be tolerant with him.
