That Miyuki brocon scene was more graphic than I had imagined it to be. It really emphasizes how abnormal their relationship is.

What magic did she use against Tatsuya? Was it the new non-lethal magic that she just had Tatsuya install? If so, he was basically used as a guinea pig.

I agree about the sheer stupidity of the club members. Being someone who practices martial arts, seeing how Tatsuya easily fended them off should have already given them the impression that they are unable to beat him. All of them even started using magic!? How pathetic must Mari's group be to allow people like this to just randomly use magic and attack other students, much less disciplinary committee members? If they did their job properly, students should be afraid of breaking the rules. It's like they don't even care.
