Well, at first I was a bit disappointed. I was expecting the gang to
suspect Tsukino, only to have her turn out to be innocent, because the running moral of Kotorou-san is that no matter how bad someone might seem at first, they're basically good, deep down, if you give them a chance. Of course, it turned out that she was indeed the attacker, but they still managed to keep with the theme somehow.
I appreciated Moritani's skirt-flip aversion gag at the beginning; there was more than enough drama this week, and some dumb, goofy comedy was sorely needed.
