[Nia can't say a thing there. No one knows her secret -- except Goku, the bastard! -- and she doesn't want them to. Keeping her identity hidden is important, she can't say why, but deep down to her literal core she's convinced that she has to. So the truth of her shinki power, that it's just resonance, can't escape her lips.]

Yeah, that's literal. When you need it, I can give you extra strength. And -- there's a lot more to it, but you'll learn that over time.

[There's still fear lurking inside her, wondering what she's done and what will come of it. But equal to that fear is her willingness to see it through. She doesn't call it courage, but she won't let fear make her falter. That's for sure.]
