Quite a nice episode, I really love the new OP and ED, especially the OP.
Well, while Sugou is exactly that a**hole I expected him to be, it's the same for Sugu and her cuteness ^^
The kendo fight was just one thing...NICE. I really liked and it was quite well animated
The surprising thing imo was the pacing, I expected the E-mail sth around 5 mins earlier, maybe the pace is really done well for the rest of the series
And ofc the biggest change is the overall change in the mood, starting obviously from the OP everything (apart from that part with Sugou) is a bit livelier and maybe aswell friendlier, dunno how to make this clear but you simply feel the change in the mood ^^
