The manga is really beautiful and well made, is a pity the anime has the "animation" problem, maybe they'll do it again as a proper anime because really, the story in the manga is everything really set perfectly. Is just incredibly good!! How Lua evolve and learn to build up confidence in herself, thanks also to Sven and the others, how Sven learn to value up himself too, and this thanks to the romance that build during the story. How Arianne is depicted as the villainess, the "true" one, as well Father Flix. The last battle between Lua and Arianne was also incredibly good, stlye, butalso storywise, and all the constant sense of suspence was managed sooo well. Also, the ending, not being rushed but also not being too slow.
I really think this one, considering the villainess/revenge genre, is one of the best manga ever done recently.
If people can't withstand the animation in the anime, please do yourself a favor and go read the manga, because is really totally worth it.

ABSOLUTELY RECOMMEND IT > 10/10!!!!!
