In all honesty, this is one of my favorites. The characters and their development is actually great. This anime is actually perfect for one reason. Not because of the gore. Not because of the story. But because they did something different. They did something that was never before seen and they also put some stuff like death and cute girls in there, but they did something new. And honestly, they got some hate for doing this because a lot of people don't like it when something new happens and they only want to see something they've already seen because they know they'll like it. But they don't realize that this is how they find something new, that they'll like even more in the future.
Overall, 9/10 great story, great characters, pretty good art, and sound. And they defied the common mind and made something new.
