D-Saga: The Code of the Saga Clan

My name is Hypace Saga. I am of the D-Saga Clan. We are the oldest of the living Demon/human species. I've been dating this human girl for three years now, and things are getting pretty serious. However, she wants more. She wishes for marriage and children. I know because I can read her mind. But I have not told her of my true origin. So, I decide to take her on a special date and I plan to let her in on all my dark secrets.
