||Tetsujin, Narrator 1
is the disciplinary master who also became class F's homeroom teacher after the first classroom wars when the Class F was lost to Class A. Nicknamed Ironman or Tetsujin, he is extremely strict and drags people off to remedial classes whenever they lose a battle, regardless of location, often saying, "those who are KIA must receive supplementary lessons!". He is also said to possess godlike physical abilities. He has once shown a considerate side when Yuji and Akihisa apologized for leaking out test copies.
