Commentary:
Similar to the last page I showed this power, I left the forth panel with lighting effects so the reader can know what color the aura is actually supposed to be. And yes, as some may have noticed, this is a Dark Power aura. When it was first shown, Dark Powers weren't explained yet, so it would be easy to miss that unless you reread chapter 19 after that moment.
When Erika used the power on Jamon, Jamon didn't think much of it. Mako is a bit more experienced with powers in general, which is why I had him assume that Koko was using a power on him.
