Choice
I could never have easily returned to being human, having never known a normal life to begin with. So when we were given the choice I knew that I didn't really have one, but feared that my only friend would chose to return to that normal life he is lucky enough to have had before this all began. So when Daisuke's response to the fact that we had a choice was not a quick 'I give up my magic' but instead 'we need to think about this' I was overjoyed. And when we came to tell the Eternal Guide our decision, I managed to sum up all of the feelings I had about this in one sentence "It would cost more to give up magic than it could possibly cost to keep it."
Sleep
I don't fear sleep anymore, even with the way I meet Krad in my dreams, what with him no longer being the monster he was while bound to me. Ironic that he only became someone I could stand having been part of my life after there was no more chance for that to happen. But I sleep, dream of Krad, wake up, and often haven't gotten enough sleep that I should be functional in the day, yet somehow feel well rested in spite of this. It seems that one of the effects of magic is that less sleep is necessary, and given that Daisuke and I only really dare fly at night that's a good thing.
