I have an idea for the pokemon RPG. We make a whole new bad team, and they work to use souls to awaken Darkrai and cause chaos in all the regions, starting with Sinnoh. Menin's mother is part of this evil team, which makes Menin herself a member as well. Menin uses contests to lure out souls, then checks to see if one is fully light with no worries at all, as the awakening of Darkrai needs a soul of darkness (which is currently not being worked on), and a soul of light.
Based on my character, I bet you can guess who the soul of darkness is if this works out...
