I've seen it too, McIcy. I'mnow officially seperating the storyline from the manga and seeing it as it's own thing.
But so far, the start seems reasonably similar to the manga's "second saga" (After the Totaku incident.) It has a different start to the manga, as Ryomou gets what I believe is a different looking Gyokuji, aka "Soul of Conquest," which she recieves from Ryofu.
Apart from that, it goes to the story of Kanu and her group.
The action itself is pretty impressive. If it continues on like this, I may like this series far greater than the previous.
