Some of the " crimes" they stated are rather stupid. Destruction of personal property is a valid crime but the others. . . Since when is spreading groundless criticism a crime? Has anyone ever be expelled for a reason like that before? Unless it gets to an extreme degree, I don't think any school administration will care. The " crimes " then become more and more petty. Ignoring and insulting someone? Who hasn't. Not sending invitation for school tea parties and gatherings? That's not like trying to expel someone who didn't invite you to their birthday party. The only way I can picture it being valid is if Tia in charge of these gatherings and it is hosted by the school. Even then, I think she would just have been reprimanded by a teacher. Not exactly school expulsion worthy.
Just to clarify, I know she didn't actually destroy Sophia's property and there is another reason for the others. I'm just baffled the student council would be stupid enough to frame some of them as crimes.
I think I probably like this chapter the most art-wise. I really like how the artist drew Tia's expressions.
On another note, is there another villainess manga with a villainess named Sophia? I feel like there is but I can't recall any.
