Mystic Destinies: Serendipity of Aeons

You are an intelligent and practical nineteen-year old girl, in your first year of attending one of the best universities in Japan. A few years ago, your mother married a wealthy business owner. You plan to study hard and take his business over one day. Life can be tough at times, but it isn't complicated.

That is, until your mother takes you to her ancestral home. It's there that you learn of the supernatural world when she performs a ritual on you. You learn that you are not human, but actually a rare type of being called a homunculus. You were created in your mother's image to serve as a transfer for her curse of immortality. And apparently, her ancient and potent sorceress powers.
