Well, overall this manga is good. The story is quite interesting and enjoyable. But, too bad, the author chose to drop it because he/she had a bad health. So, it didn't have a proper ending and.., yeah, of course a cliffhanger. It's really a shame, since the story has gotten so much interesting lately, but.., yeah, it has ended and there's nothing we can do about it. I hope the author will continue it someday in the future. Because, there's still a lot mysteries that hasn't been solved yet.
