After hearing the description of the Soul Battlefield from Isabella, Nightingale began getting depressed. "Do you mean that you also don't know how to make His Majesty wake up from the coma?"
She shook her head. "This is unprecedented, and I have no idea how to deal with it... But Zero was absentminded for a while when she was devouring Garcia. At that time, she explained that she had found some interesting things in Garcia's memory and so it took her a long time. Zero has had a more complicated life than anyone else, so if Roland wants to accept these parts of Zero's memories, it may take some more time. But as long as he's alive, he'll wake up naturally."
Nightingale could not be sure whether this was true or not, but she could tell that Isabella did not lie. At least these conjectures were heartfelt thoughts from Isabella.
But Nightingale also knew that the situation was not at all optimistic.
