The ones I call demons travel Earth's realm freely without being seen unless they want to be. It allows them to do their work in the most efficient way possible. So most humans don't know about them, not unless a demon wants to do a deal with them.

But really, the idea of demons is something humans created. Anything that could remove, destroy or damage the soul is called a demon, right? Which means in a general way, any kind of person could be a demon.

So even if someone says there aren't demons, I think there probably are.

[Mahdi notices how pointedly serious he's gotten. All of the rather childish enthusiasm that normally tilts his words upward is gone. He smiles a little.]

Heh. I get a little bit serious when it comes to that kinda thing, sorry! And if you're a human, I'm not even supposed to discuss it with you. If my bosses ever show up here I'm in big trouble.
