I must say I didn't read the manga altough I have it but I saw the anime...hmm it was a little bit confusing in some parts and the ending wasn't very good but I loved it and adding Shin that made me love it more!
So I don't care what others say from my point of view it was much better than many,many others,the art looked good also,it had a little bit of everything^_^ but that ending still annoys me!
