Cyann Hure's Questions (2)

So, I read a manga a few years ago, I believe a shounen ai and fantasy type with old school drawing. It's about a guy who's the reincarnation of a "prietess" who's very important for a group of super human. If I remember correctly, she was the only one that could heal symptoms cause by theirs powers, and I think it had something to do with plants. Anyway, she's reincarnated in a blond guy and is found by her/his past lover, one of the superhuman who has dark hair and don't talk much. Any idea ?

So, there is this manga I've read a long time ago, and now that I want to find it, I really can't remember the name...
It's a yaoi about a guy who can understand and talk to birds and a guy who can change into a crow
So you guys have any ideas? I would be so thankful !!!
