Rainy Lionheart and the Wizarding world

Follow the history of Rainy Lionheart, A girl lost in a forest with only her strange magic to trust in when she was four, and her journey to become the most powerful witch in the history Expect Final Fantasy magic and other Square Enix games. And obviously expect a partial op mc. I don't own anything on the fan-fiction (not even the surname of the OC xD) as it is property of J.K. rowling and Square Enix.
