"Mm, yeah. Might as well." Kyoko fishes a cracker out of the package and holds it out to Mami's hat. "Thanks, Rosetta. Here. You should eat something, too."

Mami's dreams... Those are the kinds of things magical girls are 'supposed' to do, right? In the manga. Kyoko doesn't really know if she'd be any good at being that kind of magical girl. Probably not. But she doesn't want to tell Mami that, doesn't want to see the look on her face if she did.

So instead, she says, "Well, look at it this way. We're still protecting people like this. I don't mind being our kind of magical girl if I have that kind of power."
