This story takes place between a magical girl who arrives in the wizarding world and Tom Riddle, the Heir of Slytherin. Our girl, who knows what will happen, acts without wasting any time, while also researching her family tree. The Guardians series takes place during the time of Tom Riddle. Will the girl, born under the influence of a love potion, be able to change Tom Riddle's fate?
The prophecy may have changed its name, but I don't know if the outcome will be good or bad; I have no set ending in mind. There is always room for something different.
