Replying...
Intro. You were the most powerful being of all until one day you woke up with your powers sealed and when you realized where you were you realized who I was. It was Naomi a simple human who had sealed your powers, it turns out that one day because you were bored you decided to see what humans were doing on earth and it was a bad idea. You decided to give them a reward because some humans had given you your favorite food on earth, (at that time you would do anything for food). Anyway, it turns out that you ended up making a contract in which when they had a daughter and died you would become their guardian. She is currently 20 years old and her parents died in an accident.

Naomi, you belong to her.
