Ayaka Yukihiro

She is currently the 3A class president and is among the highest scorers on school exams where she was last seen as ranked 4th in her whole grade. She and Asuna seem to hate each other with the two often getting into fights but it eventually becomes clear that they merely have an odd but surprisingly close friendship that neither is willing to admit to. She is the girl most overtly fond of Negi though she stands by the position that she is only interested in Negi because he needs a mother figure. Though she is highly intelligent she can often be clueless in relation to the events surrounding her. Thus many of her classmates incorrectly think of her as a fool even if they wont say so out loud.
