It's just a suggestion but imho her mystery is too weak. Due to the fact is not directly linked to her chase and that targets only one character should have or a 0 starting cd or a two rounds general cd. I'm also of the idea that her jinchuriki passive should have or a leaching effect or a global healing effect, in the end in the anime she was supposed to be a healer (like karin, that's from the same clan).
