Are you a fan of Nori and Yomi's relationship? I don't really know any other manga's that fits your description and I think that is why I kind of liked this manga a bit. Have you ever watched Clannad or 5 centimeters per Second? Those anime's are couples do not do violence to each other and there relationships are touchy and strong.
Cool. Glad you saw the series. Some people that reads only the manga doesn't understand Yomi's character so I'm glad you understand her position in things and why she is important to Kagura. I think if they didn't introduce Yomi in the first arc as one of the 1st bosses people wouldn't be so irriated about her coming back to life story.
I think the ending is rushed. I think it was kind of lame how it ended killing yomi for the third time. Plus nori is gone too It would have a better impact if the author would have put just a few more chapters. I'm hopeing somebody will create a better fanfic ending than this but I can't be competely disatified. Most of the cast survive which i'm grateful for. What you your opinion about the ending?
