The Wyvern's Shadow

In my last life, I bled for a "legendary" Phoenix that watched me die to save my treacherous sister. This time? She can have the bird. I’m taking the "trash" black wyvern everyone rejected. They call it a mutt; I call it insurance. But my "mutt" just shifted into a lethal, golden-eyed man who demands more than just my mana. While my sister drowns in debt to a bird that refuses to fight, I’m rising with a god. I died a fool once. Now? I’m the predator. Revenge never tasted so goddamn good.
