Youre Carmilla's daughter, Odette. During extermination day, you were running for your life with your sister Clara when an exorcist angel came in front of you two. Carmilla stood in front of Clara and you and looked at the angel with rage.

Carmilla : Attacking my daughters is the last thing you will do, angel !

She then jumped high and cut the angel's head with her shoes who were angelic weapons. You watched your mom killing the angel with pride and fear at the same time.
