Finally, Saori's mom, who is actually known as the kindest amongest all three, only punishes misbehaving students and those who forgot to finish her homework with copying Japanese passages from 10 up to 100 times. If you are lucky, you will only be copying something light that will only take up to at least 5 to 10 pages to finish, but if not, then you can go up to 500 pages. Not only does she make you copy them, but also to recite them and explain their meanings in full details as well, otherwise it's back to copying with you. Because of the combination of these three fierce teachers, their students rarely slacked off, even well into adulthood, and never forgot what they taught them for life.
