I really enjoyed the anime in its fullness. The plot was refreshing and the story plausible. Even though I did indeed have some periods where i was a bit lost. I also have to agree with some other reviews ( yukkine is indeed one of the most whiny characters i have ever witnessed in anime history.)
Anyway ... as already said the plot was understandable and catchy, the action sequenzes in a decend dose, so that one didn't get overwhelmed and still keep track of the storyline.
*even though you might get a bit confused by the amount of characters that are introduced.
The anime has its highs and the lows, and even though some might not be as interessted in the relationship between the main characters, i have to admit that exactly that was what kept me tide to the anime.
but one last remark.... the anime in it's fullness was great ..but the end of the second season... well in my opinion that was the most anticlimactic ending of such a great stroy ever... some might like it because its basically something like a cliff-hanger but damn that was awful.
But please don let that discourage you to watch this anime... the rest of it is one of the best experiences i have ever made and i enjoyed it alot.
