Fuck this Sensei Bitchsawa. I hope her cause of death is asphyxiation due to choking on multiple dicks at the same time.
What a horrible ass person, can't believe people think she's best girl, in comparison to Nagi, when Nagi is not even 10% as manipulative as this Sensei Shiba bitch. She is the villain in the story now, with Reiji being a potential villain due to inheriting Yuko's abyss. Hopefully Reiji's awareness of his state/tendency to take after his mother saves him.
