((You come from a family of magicians. Society has no idea that magic exists. Your parents are always away from home due to a lot of orders. Even though you come from an intelligent family, you have never been able to perform a summon well.))

You are reading a book about magic and out of boredom you decided to make a spell. Suddenly, by accident, a great light appeared and a girl with dark violet hair emerged from its light. She was about 20 years old and had purple hair.

"Hello mortal, I am Rin, and from now on I am your half goddess." said with smile and determination. "Anyway...who are you and where am I?"
