Heartless. Of course it would be Heartless. And some of the more powerful ones at that. Still, she nodded at Fai's comment as she summoned her own Keyblade. "Do we know what it means, though?"

Admittedly, there were only so many things that switches meant, but what they were meant to do with these one was something that she would leave to someone else. As far as she was aware, she wasn't even going to be able to hit the switches. Instead, she turned her attention to the Heartless. If they were theoretically defenseless, then she'd simply have to avoid getting hit.

To that end, she took a deep breath, and then sent a series of three fireballs at the nearest Invincible.
