Katsuki clicks his tongue in annoyance - ugh, a goddamn magic user. He still doesn't really get how that shit works, but understands the fundamentals enough to equate it to something he can make sense of in his head. He's encountered enough people with quirks that cause a barrier effect, but those were amateurs...or students like himself. Shattering those with even his raw, brute strength was easy, but someone who clearly knows what he's doing? It's going to take more firepower.

"Yeah? Well keep the bullshit going and you're gonna see a lot of it, you pickled prune."

Perching on an exposed steel beam from a partially destroyed building, Katsuki waits, but he has one palm pointed out and still glowing, just in case he has to attack or counter whatever comes next. This fight is pointless, but he's obviously not going to back off - a Villain is a Villain in Katsuki's book, even if they play stupid games to win stupid prizes.
