Hovering along on the magic book, Francis manages to catch up with them, having been left in the dust earlier by Pig.

Rita acknowledges her familiar with a glance, then tries to also look up, shoving Yuya's head out of the way as she does.

"Ugh... of course he had to go set up all the way up there!" she complains, then eases off of Yuya. "Light cancels shadows, doesn't it? I don't have any light magic, exactly, but I can use the light emitted by fire magic to screw with any shadows he might try to use." Fortunately, in an open space like a rooftop, there shouldn't be that many objects casting shadows to begin with... she hopes.

Of course, she wouldn't complain if they could go fight him literally anywhere else, but she doubts Childermass is going to accommodate her preferences.
