Even though their Father was absent during this time they lived a happy life with their mother, however everything changed when they were 12 years old as several exorcists from the arclight family came to eliminate their family, in an act of desperation their mother acted as bait and held of the attackers enough for the sisters to escape. This day marked their vow to become strong and get revenge for their mother. [Highschool DxD Fanfic.] My first ever fan-fic apologies if there are in consistence to the main story.
