[What a fulfilling life, riding on the coattails of others. Katsuki would rather struggle to his his dying breath actually doing something than give up the ghost like that. Foolish? Maybe, but he's not the type to just let someone stronger than him wipe their feet on his face. He can bide his time, let that rage build up and fuel his drive and resolution, but he will never let anyone push him around, especially pricks who THINK they hold all the power. He's taken down someone like that already, and you know what? It was perhaps the most satisfying thing he's ever done in his goddamn life. And he's still just a teenager.

If she asks, he'll show her, but until then Katsuki is quiet and merely watches and listens, frowning deeper when she speaks again. He...really doesn't want to take this seriously, no, but even he's not so fucking stupid and deranged as to keep believing this is all fake. No, it's...gone a little too far past that, much as he hates to admit it. He will, however, continue to deny any one of the people he cares about are dead. That lady can suck his dick.]

So it's a bartering system. Tch...of course. You want something, you can't "pay" for it, you have to trade... It's a sleazy way of tacking on additional time to our stay here. Oldest trick in the book - even our own spirits and folklore pulls that crap.
