The Eighth Deadly Sin: Ban's little girl (the wolf sin of sorrow)

The year that Ban was captured he found a newborn baby girl that he lovingly named, (y/n). Six months after Ban adopted little (y/n), he was captured by the Holy Knights. Then Ban along with (y/n) were incarcerated in the Basteen Prison for 5 long years. At which point Meliodas, Diane, Elizabeth, and Hawk come to their rescue. She may have grown up in a prison but she will grow up to be as strong as her father.
