Okay, it's pretty hard to review one episode, but let's still try. Was it worth the wait? The answer is surely yes. Except for an interesting story of its own, it also gives background to the manwha (Later on they mention it, but not much. Guess they thought this one is enough). Things that aren't really explained suddenly get clearer. Unforunately, there are some question marks. We didn't learn much about Rai (Except for how he got to the 820 years sleep), but we surely learned a lot about Muzaka and the reason for why all the story in the manwha actually started. As I already said,one might still ask himself\herself a lot if he\she didn't read the manwha, but it's clearly can be seen as ova on itself and nothing more.

Okay. now let's focus on the ova of its own:
---------------------------------------------------------
The story was set clear but pretty depended on the fact that those who watched it already know the plot of the manwha, a disadvantage in my opinion. Sure, it helped to decrease the time needed for an explanation, but still.

The relationships among the characters were shown very clearly, and even if you see it for the first time, there's no question about it.

It was interesting to watch, though it was a bit excepted (though I think that even those who didn't read the manwha may agree with me). But there were some new facts, that even for those who read, can be still interesting.

I know the review sucks, but I really recommend it. I just don't know to explain myself to well. :(
