This reminded me that according to Wakana; the rest of the students, outside Sensei's class, are basically scared of and want nothing to do with his class:
Sensei's entire class is basically socially ostracized by the rest of the school. His class, itself, is a clique.
I mean, they have a girl that is known for carrying a knife, another girl that supplies drugs, a yakuza princess, the two richest girls in the city that study martial arts, a Zealot, a girl who works at a porn shop, and another who works at a bar. Then there's Noodle girl, Watermelon girl, and the two Incest girls. All of which are virtually fighting over their creepy teacher. The rumors alone have to be insane. (Not even getting into how Ayane has apparently killed some of the staff, and brought both guns and blades to school, lmao)
