I don't watch tons of anime but this one I loved it , I think it is a nice story quite original I would and the fact that there is only 2 seasons and the story ends abruptly left wanting more, I have read 9 volumes out of 14 wainting for the english translation for the others the series in my opinion summons the right amount of everything if you are a balanced human being if you are into more violent stuff you might not like it .
