Fix it?

[Kaz pulled a very strange expression at that - as if he wasn't quite sure how to even take that. He very much doubted that it could be 'fixed'. His soul was glued very solidly with the other Bels, and to Bel himself - he was very certain that any attempted fixing to pry them loose would kill him or traumatise his soul badly enough that it would split apart again. On the other hand, there was a sort of wistfulness. Becoming a demon wasn't an actual choice for him - it was just something he had to do, or have himself, his friends, and a large chunk of Tokyo's population die. A noble sacrifice of his humanity, yes, but it was something that he didn't necessarily... want]

I don't... I don't think that's possible. [Kazuya sighed too, as if Kevin was being the troublesome one] Like I said, it's complicated. You can't just shake them loose and, bam, I'm fixed. It's very... [he made a twisty gesture with his hands, trying to convey just how messed up it was] It doesn't matter. I'm not a danger to anyone, so you shouldn't worry, anyway.
