Read the whole set in one long sitting, and what a treat! The style of this manga was very off putting at first, but I gradually adjusted to it. It's fast paced and packed with action. The characters are drawn to be easily recognizable, but the very cartoon like style diminishes their impact somewhat. Don't be dissuaded by the amateurish looking art though, because the story is epic, and I don't use that word lightly. It made me think about the concept of absolute evil, and the evils done by man to his fellow man. I wondered about the nature of friendship, and the need to protect those close to one's self. The plot is magnificent, and progresses so quickly and dramatically that you may wonder if you've missed something. Highly recommended for all serious fans of horror, supernatural, and action.
