If you a truly a anime fan, and do not have a weak stomach, you must see this series. The drawing itself is compared to Claymore and Vampire Hunter D( the first one) which is pretty decent, but do not get me wrong for those that are all about the drawing, the plot is phenomenal. However like most good anime series it leaves you looking for the next disk, or next season which never came some say it was too gory and is directed to a specific age group not suited for kids and b.s. , Like I said it leaves you wanting more, but unlike some animes you will not de dissatisfied at all.
