takes the form of a mummy, which can be seen during the Test of Courage in Episode 12 of Season 2. Fumizuki's Teachers Kaoru Tōdō is the Principal of Fumizuki Academy. Her name is never spoken in the Japanese version of the anime. Shin Fukuhara was the first homeroom teacher of Class 2-F, who in the anime became the narrator after the first classroom wars, and was replaced by Nishimura. Sōichi Nishimura is Fumizuki Academy's Disciplinary Supervisor, who becomes homeroom teacher for Class 2-F after their loss to Class 2-A. Nicknamed or Tetsujin because of his hobby of participating in triathlons, he is extremely strict and possesses prodigious physical abilities, like being able to jump with the best of them. He also supervises remedial classes, dragging students off for supplementary lessons regardless of their location whenever the points of their Summoned Beings reaches zero, declaring, "Those who are KIA must receive supplementary lessons!"
