Takanori is a teacher at FGD who is known to be the least liked teacher and the most feared because of his strict...Well, everything. Strict deadlines, strict instructions etc. He also gives plenty of schoolworks to his students and makes every class work hard but only because he believes that it's for the greater good since that was how he was treated when he was still a student. He also works hard to make sure everyone passes his class and even tutors students falling behind for free.
