Petition for Saotome-chan to be a recurring character! She would fit in with the girls just fine!
The teacher was pretty irresponsible, though. She should have taken this more seriously and sided with the students of her school. It won't be hard to find out what schools those boys are attending. She and the principal can report their behaviors to their schools and they would be in deep trouble. Author really disappointed me in giving them such a slap on the wrist like that.
