Holy shit I actually feel bad for Jimi-sensei now.
I still wonder why he still clings onto being a teacher, I'm assuming that it's his only way of livelihood now because of the shit the chairman's little sister did and the aftermath on his societal/career status where he used the incident as "blackmail" for the chairman of the school to keep a job.
But man, that shit shouldn't even be called blackmailing. It should be seen as a compensation from the chairman's part, her little sister was torturing him and when shit blew over he gets framed as the murderer of the horrible little sister's suicide.
