"...Dangerous?" Accelerator asked, letting out a small laugh as he looked down at the girl. "So you're telling me that trying to scare someone when they're there isn't [i]just[/i] as bad? Or, y'know, the fact that you scaled the building to do that? Don't go telling people off when you're making just a big of a mess as they are. Got it?"

Sighing, Accelerator shook his head before trying to process the incident that had just occured. As far as he knew, Academy City was the only place with access to this sort of technology, barring any sort of illegal smuggling. Even if that fringe case was the reason she was able to come here, it still wasn't enough to propel her up the many stories of the building in one go without putting considerable strain on the machine. That, coupled with the fact that espers were essentially an Academy City-exclusive...

"...Oi. Don't tell me... You're not one of those magic-using crazies, right?"
It would make perfect sense, of course, after what happened with Othinus and that weird mummy-thing he saw blasting down the street chasing after that spiky-haired idiot and the Number 3 the other day. Even though Touma had resolved those issues, the fact remained that there could be residual efforts to take the city down... Which would more or less spell disaster for the world. Would they be trying to lessen the city's defenses by taking him out of the picture? If so, then what of the other Level 5s? Imagine Breaker?
But, once again, that was all dependent on how hostile these forces ended up being. Jumping to conclusions would only cause trouble. But if his assumptions proved to be correct...
"And... Do you have any intention of taking down Academy City?"

That tense moment, however, was interrupted by Last Order seemingly dragging another random person into the mess--a blue-haired individual in... Well, it seemed to be more cosplay. Pausing to look at the girls for a moment, Accelerator sighed and massaged his forehead.

"Last Order? Why did you...?"
"'Misaka saw this person climb up from the edge of the roof and offered to help, so Misaka brought her over here!' says Misaka as Misaka directs the blue-haired lady to Accelerator."

There was a moment of silence before Accelerator began speaking again.

"Climbing up this many stories isn't within the realm of normal human abilities, and I use the term 'normal' in the most basic sense of the word. I can only assume that you're magicians, at the very least. So let me make this clear: you mess with Last Order, you die. Understand?"

"'But Misaka doesn't think that they're bad people!' says Misaka as Misaka runs over and tugs at Accelerator's jacket."

But Accelerator remained there, gripping his cane tightly as he prepared for the worst. A two-on-one while protecting Last Order was highly disadvantageous for him, but if he managed to disable one of them quickly enough...
