Koutarou Azumamiya

Azumamiya is the master of Nonohara Kaede and a member of the kendo club. He is considered the weakest member of the club because his strikes are random and dangerous. He has a vulgar mouth, but it is Kaede's duty to refine him into a gentleman. When he is in trouble, he calls for Kaede to fight for him. Both Koutarou and his butler Kaede are references to "Mahou Sensei Negima!"
