He's not going anywhere. I was just thinking.. the reason why in Amatsuki, why Toki had special powers, and was able to fix things, was because he was the unwritten page. He didn't exist in Heaven's Net, so he could disrupt it. The story hadn't planned for him.

A prophecy is like a story, isn't it? So couldn't someone else the world hadn't planned for disrupt it in the same way?
