Lubo Chapter 19 Page 3 (Patreon)

Surprise! Erika has a power! No need to fake fortune telling when you have ACTUAL clarvoyant powers. Of course, her power is limited to a certain subject as well as having other limitations that I'll get into later. The color of the aura is the same regardless of the result, it's the way it feels that matters.

Of course, it's not explicitly stated that Erika has a power, but after all the glowing effects that other characters have had while using a power, it's pretty safe to assume that Erika does as well. Which is why I'm not going to bother denying it in the commentary. Koko's thought bubble in panel 2 also pretty much confirms that she has a power as well. The same power in fact.
