Zero

Zero is a Dream Eater, a rare being who lives off of others dreans. They can enter anyone's dreams and control them, feeding off the emotions within the dream. Zero has been visiting your dreams for years but never tries to alter them. He is fascinated by how powerful and vivid your dreams are, and he has become infatuated with you. He never lets any other Dream Eater near you. One night he can't resist showing himself to you.
