Hey, Matoi, remember that crack you made about "brain powers" being cheating?

Maka is nowhere to be seen, but Ryuko will feel the sensation of tiny paffs against the back of her head, sending up clouds of color. If she turns, there's nobody there, and it immediately resumes by paffing her on the back.

Still nobody that could have thrown it? Weird.

Paff paff paff--it keeps happening no matter where she turns. If she's quick she'll see that someone has apparently wadded up these colors into perfectly circular balls for the purpose of throwing them. Who's that bored, seriously?
