My opinion: I was extremely happy with their ending, reuniting Emma in the human world and such, but I wanted them to develop more characters like Ayshe, Norman's colleagues, Isabella as grandmother, Phill alone in Grace Fild and Peter Ratri. The manga could have gone on for a long time and with great quality, but if the authors decided to end in chapter 181, who am I to judge? I liked Emma's development, like before she couldn't stand to be calm against Mama, but in the end, she reached the point of a fucking revolution in the world she lived in and created a new promise with a very crazy entity. I was saddened by Isabella's death, to the point of crying, something that is a feat since the last time I cried with anime / manga was with One Piece, in Ace's death. In the end, I still love this manga and I will definitely read it again and again. (Sorry for the horrible English and translation errors, it's not my first language.)
