Hiko is an animator in the day, and streams games with the homies at night. She do be just a.. regular pal. Good ol' human being. Oh, she has forged pacts with a bunch of powerful demons too, but that's not that important.. right?
A human being who sometimes summons demons to help her out in a pinch. I think that means she might be a Faust. Or a Warlock.. a Witch? Never mind, let's keep it to human being for now.
