Query: Don't bother

Okay, first off I really enjoyed it, but there's a major flaw, these volumes (1-4) only have 5 episodes each and there seems to be no plans on releasing more so going with these volumes you'll only make it to episode 20 out of a total of 50 episodes. If you really want to watch this series you should go with the increadibly expensiveBlood +: Part One with Bonus DiscandBlood +: Part Two, however that (at the time I'm writing this) is extremely expensive, approx $250 for USED and $400 for NEW.So if you don't mind not finishing the story that at episode 20 is still building up, I encourage you to get this, but if you like to see things through to the end (like me) you're better off without it.
