I know people will disagree with me, but I can't help but think that the crow Girl has some connection to Ai. I never thought that she was a reincarnation of Ai but as we all know, she knows every event that transpired and in detail.

My theory is that she has something to do with Ai's death and manipulated the events that happened which led to her getting stabbed and probably got Goro killed as well. She knows too much even that they are reincarnations and with the way she spoke to Ruby and Aqua as well as the vibe and attitude she gives off, I wouldn't be surprised.

I know it probably sounds far fetched, yes, we know that their father has kills women and like to see them die slowly but at the same time I don't think a cold blooded killer, especially him would visit Ai's grave in the fist place. Something doesn't sit right with me, I personally feel like thing aren't adding up. I think that the author is trying to make us think that Kamiki gave their location away just because she contacted him like he's trying to bait us.

Even if he has a twisted mind and in his own twisted way, loved Ai, why would he visit her grave in the first place if he killed her. It doesn't make sense to me. I read to many stories to know and feel like all the pieces don't really fit in place. What if Aqua kills their dad for nothing. I don't care if people agree or get at me or not. That's just how I feel, the crow Girl, even if its just her personality, seems too suspicious to me. She's a red herring for me. I'm pretty sure that a few people have the same thoughts.
