I wasn't into its prequel, Yurara no Tsuki, but weird enough I'm so attracted to this story. The heroine is not like Yurara no tsuki's heroine, Rasetsu is much stronger and she knows who she is. I can say that she kicks ass, I love her. And the boy? Personally I love Yakou even since Yurara no tsuki, and now I love him even more.
The story begins with fun cases as the opening. Like the other great mangas out there, the tension is built step by step and as the story goes the plot becomes more and more complicated. Of course this wouldn't work for those impatient readers. But for me, it works because I just hate the type of story which goes too fast like 'oh it begins', 'woowie it's climaxed', and then in the next book 'whoot, it ends'. No, I don't like something like that. I like something that's thoroughly planned and slowly but sure reveals bits by bits its mysteries.
The romance part is really good because they don't rush things. They are human with problems. They won't fall in love THAT easily without going through many things, moreover that they have dark pasts. If they do fall in love that easily, then that's absurd and unrealistic, I'd throw the books without reading them further. Luckily, the romance goes just in a perfect pace for me so I can say I LOVE it very much.
One of the mangas I love. I own thousands of mangas (FYI my country is one of the biggest manga publishers in this world) and I read mangas since I was five. As I grow up I become more and more picky, as I've read so many books that I become bored to read the cliche ones and the unworthy ones. So if a manga can pick up my interest, then it's special. I don't know about other people's taste, but so far this is one of the few mangas I found worth to read.
