Also I found that the variety of characters is something that really made this really awesome to read and enjoy, the fact that those personalities are either strong and simple, make it easier to understand the character's feelings and can possibly, as I said earlier, make you identify yourself with someone.
I do not know how suspicious I'm to talk about the art, but I found it really enjoyable and easy to understand what happens on the scene, anyway it is a great work indeed.
To finish, in the overall this story is very narrowed to a specific type of people since it's genre is not something that everyone could like or enjoy, but for who enjoys that type of stories, have fun reading it.
