friendly information: I've seen it and it's not really a sequel, since about half of the volume was mangetsu no ou, though there is some difference like...( http://imgur.com/a/4Vk3K ) but don't worry there's kinda like 3 chaps that weren't here and it also has extras of Zhen.
THIS STORY HAVE A SEQUEL!!!!!
