Air Fire Black

Air Fire Black is the daughter of the infamous 'mass-murderer' Sirius Orion Black and the famous author of 'Flames are powers' Rolanda Greengrass. As the days bleed into years, Air starts to think that maybe Sirius is her father and he is innocent and was wrongly accused by the Ministry of Magic. One day during Air's summer break after finishing her fourth year at Hogwarts School of Witchcraft and Wizardry, she goes and visits her father. Though she has only an hour left before she has to leave, Air and her father make plans to break him out. Air has the idea that when she leaves, Sirius will turn into his animagus form and wait for his food to arrive and when ot ar rives, he can slip out past the dementor and make a run for it. Air would be waiting at the entrance for him and when he arrives, Air will turn into one of her tenzimagus (you have ten animagus forms instead of one) forms and they will both go to Hogwarts together and Air will take her fifth year education while keeping the secret that Sirius Black is her father. Will she crack to saying that Sirius is her father or will she keep her mouth shut and say she is Regulus Black's daughter?

I do not own anything from Harry Potter. I only own Air Fire Black, Rolanda Greengrass, and any other character or place not from Harry Potter.
