Assassination Classroom, S.1, Ep.9 - Transfer Student Time (Patreon)

I hate that I get teary eyed when I see how passionate Koro sensei is when he's teaching. A new member added to the classroom causing a huge disturbance while trying kill Koro sensei...

She couldn't help it though. She was programed to be that way.

I like what Koro sensei did to help her be herself.
