Holy shit, this is easily one of the best chapters in the entire story so far. So much personality on display from every character. Yuri in top form as per usual but her antics with Nemo are always a treat. Nemo might have upgraded herself to my second favorite character after this stunt (she was pretty close already, I love that little star-eyed dumbass).
Tomoko saying she's a bit pissed off that Yuri only gave her 75 points and the punch line that it's because she had one of the food items the previous day is perfection, classic comedy duo routine. Tomoko also had Nemo pegged from the beginning of her little scheme, it was 100% masturbatory. She just wanted to flex and be in her element.
I hope the class president saw the movie and approaches Tomoko after. That's really the only thing missing to put a nice little bow on this arc. The movie is basically the culmination of all the new friends and bonds Tomoko has made since the Pres graduated. It's physical proof that she's grown substantially.
