[Katsuki's attention is only half on his sweat when the other boy does whatever it is he's doing - some kind of sign language or something, it looks like, and then there's a gust of wind. It's...cool. He's never seen something like that in a Quirk, not with the weird hand signs. Blowing out a gust of air, sure, but nothing like that.
A moment later, it connects that it's his turn, and he focuses back on his sweat, willing it to explode if it's still there - and it does. The explosions aren't as intense as he'd been aiming for, just little fireworks and not the show-off-but-don't-wreck-anything explosions he'd been planning on, but it works.
Pumping his fist, he smirks at the other boy.]
Works. Just gotta send extra or it gets weak, apparently.
