At first i didn't think it would be that good but as you get into it, it becomes great. There is a fair bit of blood and gore but it's not that much so it shouldn't put anyone off that much. There is loads of action and it's not one of those series were the main character is just the most powerful. That makes it far more interesting about the other people involved as well. Well drawn with lots of detail an just all around a great series.
Awesome anime. A shame they did not continue it with the manga
