Jaune can't manipulate shit with an aura with his Elementals

But they wouldn’t let me win this. If Penny was something else—if she was a Spider Droid or even a super Spider Droid—I would have any reason to fear her. If she was just as strong and a normal robot, I’d tear her apart regardless of our level difference. It might be difficult in a few ways and a tad dangerous in others, but I was almost certain I’d win such a fight. Crocea Mors could let me tear strips of metal from the White Whale’s hull with about as much effort as lifting a bed sheet. Vulturnus could reach into and cause havoc on any electrical system, tearing up the power and letting it run loose. Between the two of them, I was certain that if I had to face a Spider Droid or two or even three, I would win. Not so much because I was powerful, but because I could literally just reach inside them and turn them off.

But Penny wasn’t just a super advanced robot. She had an Aura, a soul—she was a real girl.

And that changed things. I couldn’t reach into her and mess with things, even if I wanted to. I could sense her, the metal and electricity that made her run, but I couldn’t control it—or at least, not like I did with everything else. It was a matter of my Aura and hers and it would mean a clash that she’d almost certainly win. If I could touch her, fight it directly, and hold on for a while, maybe I could do something, but I was pretty sure what would actually happen was that my body would be introduced to realms of physical discomfort previously unheard of.
