After kind of weak 1st season, I was delighted when I started the sequel. The most noticable change about 2nd season is there was no big plot in play and it worked perfectly for the anime in my humble opinion. It finally become what it was supposed to be, a light anime that makes you feel relaxed and happy and not to concern about some complex story. That was the thing I liked the most about it. In other segments it hasnt changed much since first season. Art style, music and characters stayed pretty much the same with a few additions, but none of thosethings are what made this anime so enjoyable. Hope the 3rd season keeps this recipe.
