I've managed to put down a good number of words this morning. Hopefully I should have some more material to post soon.
One thing that kinda jumped out at me while working on these next bits: Really, there's no functional difference between the Book of Darkness and the Tome of Night Sky. The only real difference is that one had that Ultimate Defense Program that goes berserk all the time, and the other doesn't. That said, it would say a great deal about Hayate's abilities if she had left a backdoor into the BoD that was subtle enough that the reconstituted defense program never catches on to it.
Granted, this is something that is never stated in canon, but it would only make sense that one of the first things Hayate would do after the dust settled was to make sure she would never be locked out of the Book again.
