Damn, damn, damn. Was that a wing? Terrific. There would be no room in this place for that kind of combat if he got out. The building, while sufficiently sized for the seals they'd put up, wasn't big enough for him to fight in bankai. Especially if Frau took a winged form, too.

He'd have to dispel his own barrier around the house and take the battle to the open sky, if it came to that. And that would still leave countless people in danger.

His mouth set more firmly at that little display. So Hollow-like, all these mannerisms. But the creature Frau was becoming would not be allowed to feed.

"I don't know." He hated saying that, wished he had a better answer for her -- she looked to him to have answers. But this power wasn't of their world, and there was much of it that they still didn't understand. "Just concentrate on keeping that last barrier fortified."
