Of Fire and Life

***ON HOLD UNTIL I GET INSPIRATION FOR THIS FANDOM BACK***

When the dawn is the only other witness to the murder and last breaths of one truly innocent, a phoenix demon is born, saving the life of the innocent in the process. There hasn't been a phoenix demon in thousands of years, but when Suzuki Iruma's parents try to poison him at age 10, he gains a little sister.
Years later, Sullivan has no knowledge of what he will find when he makes the deal with Iruma's parents in order to gain a grandson, but having a bonus granddaughter seems like a grand idea!
