Kyoko sighed. "First, I can't tell you what Shell's goal is. So that's off the table."
"However, I can tell you how to catch this elusive ghost. Is that what you want to know?" When your group decided not to object, she put down her muffin. She covered up another yawn with her hand.
"The impersonator works by remaining unknown. KID just happened to be a really convenient target to masquerade as, but really, the power comes from the Noh mask he (or she, let's not discriminate here) wears. I think it wouldn't matter a bit if the impersonator was wearing a black robe or dressed as a clown. The power is in the mask." "See, that mask is a great thing to hide your face behind. Can't tell who's behind that mask, so people start making things up. The result is that the impersonator has a lot of power that he or she didn't have before but does now. The impersonator draws power off fear – fear of the unknown."
"If this phantom grows strong by remaining unidentifiable, then all you have to do is make the phantom identifiable. Reveal the phantom's face. Then his (or her, discrimination isn't cool at all) powers should wane. Should, at least." She stood up, picking up the muffin and walked out, leaving your group to wonder what to do next.
