Kyouko hadn't caught the announcement, but she wanders around enough to know when something's up.

Something is most certainly up. The ground, to be exact. She watches, impressed despite herself, when a rock just shoots out of the air. She knew about magic, of course, but the Puella Magi were more flashy, all bright colors and explosions of light. This was different, and so it was interesting. The girl in the center of the makeshift arena looks younger than her, but there's something about the ease in which she moves that suggests skill and familiarity. Kyouko knows a fellow soldier when she sees one.

"Oi," she calls out. She's carrying a bag of chips, per usual, and talks as she chews. "What are you doing? What kinda magic is that?"
