Putting aside the anime and concentrating on manga only, I can say that this is very good manga and I tell you why. Story is very good, the more you read the more interesting it gets. However, I didn't find any plot twists(although I haven't watched the anime yet). Art is great! You enjoy every illustration. Characters, in my opinion, could make it better than they are. There is some lack of their representation. As for enjoyment: it felt very good spending my time with this manga. In the end you find yourself finishing the last chapter and getting upset that story is ended. It's totally worthreading!
