According to this ,Kimyo needs to have a light source around to draw energy from it ,but I was under the impression that she got her power from the star Vega and that was where her energy came from. Can anyone clarify?

That's a really good question! Though I haven't been following her as much, there was a point where she was depowered by Arthur Light, right? At that point, it seemed like she had been permanently, but then she started using her powers at some point again. I believe that she used to have a light dependency, but the power provided to her by the Monitor from the star Vega took over after her depowering? At least, that's what it looks like. Now, she still has a fear of the dark but no dependency on a light source.

Anyone else have some insight on the question?
