At the beginning you will believe it to be one of those blood and gore kind of anime where you only see limbs and guts flying all over the place. But surprisingly, it's not just blood and chopped off limbs. With only 12 episode they managed to capture the characters of almost all the main players, gave them back stories, gave some character development and oviously a lot of action and fights and even strategic and tactical view points of a handful of them.
What made me most suprised was the ending, wasn't expecting a slice of life type of ending at all. Over all good. Worth watching.
