There's a pained sound for a moment before the solider shrugs off this rather uncomfortable feeling filling herself. It's hardly the first time that she's ended up injured before, except... Her Device assures the young woman that no such damage exists which causes her to raise an eyebrow.
N: "No damage... That's, are you sure Raising Heart? Because I don't feel unharmed here in the least bit."
R: "Yes my master, your physical body is unharmed! Moreover, my sensors are detecting something else nearby us!"
Nanoha's eyes narrow a bit, this feeling is... Unnatural, there isn't any reason she can think of as to why exactly she'd be sad right now. Scared maybe, worried sure, but sad? No that isn't right. Despite the foreign feeling, she presses on.
N: "I see, let's stay on guard then. I don't want to get caught unaware if we can help it."
The Device replies in the affirmative as its master focuses her efforts upon trying to pin down... Whatever is stalking out there, she can't make out exactly what it is. But she's ready to defend at least, that's something.
