The Art Club president seems like an eccentric exhibitionist with a narcissistic streak, who, because of her appearance, probably gets her way 95+% of the time. Though I can't fault her reasoning for being upset with what MC did with the art room, a competition to keep it open seems weird. I kinda think she's really not that talented as an artist. Once again, she's choosing a rather easy route for her art showing, knowing that it's guaranteed to garner attention for a high ranking. However, her proclamation of Love for art doesn't really mesh well when combined with drawing oneself. She critiques the MC for drawing something so boring, and yet, she is going to draw just herself, again? Maybe there's something missing in the translation, but she's an odd duck, to me.
I believe that this chapter should have been stretched into two chapters, to give more backstory for the prez and her motivations.
