hell yes. catching up with this today was harrowing, but im glad to see her ready to fight back.
i wonder what sensei's ultimate plan is. my prediction is that he wanted her to experience bullying and realize how cruel and inhuman bullies are, and then once she resolves to fight back, reveal to her that her father is the one who tormented him in the past in hopes of taking the one thing that guy cares about away: his relationship with his daughter.
i think sensei's dangerous but i dont think MC is his target, ultimately.
