Hibiki sniffs, amused. "You're over-concerned."

From the tone of her voice, she's....she's sincere about that. She sincerely believes that she can be left to her own devices without causing everything to go straight to heck.

Any and all difficulties she encounters are, of course, the other person's doing. Or the system's. Or some other external factor.

So really, Wendy has nothing to worry about at all.
