Hogwarts: Hallie Returns to the Marauders’ Era

Hallie × Sirius Hallie Lily Potter, the girl who lived, was an outstanding Auror by the age of twenty-two. After an accident, she transmigrated back to 1975, just as her parents, James and Lily, were preparing to enter their fifth year. Hallie's appearance reverted to that of a fifteen-year-old, and she enrolled at Hogwarts as a transfer student. There, she met the young Sirius, and a legendary tale of romance and adventure began.
