A great continuation of the first season.
It's really good to see that there is no drop in quality of anything - the animation, music and everything is just as good as in the first season.
Storywise it even takes it up a notch - I loved the ending and the twist. Makes me want to rewatch it all real soon to see the signs of foreshadowing.
Anime like these are the very best: You have finished watching them and have the urge to rewatch it again.
Definitely a "must see"! Especially if you like series where you can laugh out loud and also may have to cry a river...
