I admit I found this compulsive viewing and finished it quickly. It was very good but not to me a real school drama〜more like Mission Impossible using a school setting. Manga, not realism but see below for the unfortunate attempt at the end to combine the two. There is the usual sensei going to any lengths for her students but thankfully she is just a side issue here. The characters and role of the dark sensei [Eikura Nana as Takakura was just the right combination of cold computer and mysterious attraction] are good. The individual stories and problems resolved by the dark women teachers were not that original but made interesting by the characters and the manga-like way they zoomed into battle in their ’extraーcurricular activities” made me smile. What spoilt it for me was the end：very dramatic but then trying to bring together or convert fantasy into realism for me just does not work ーand I feel this is what they tried to do here. I am torn between giving top mark or taking off one for this reason but it is maybe unfair to let the unsatisfying end wipe out the very good stories. I think this is a one view only series but if it kept this guy watching every day it must be good. I am usually watching four or five at once.
