Livia and Sage are both sisters (Werewolves/Group C) 

But, I would like one voice actor for both since they pretty much sound the same except Livia is younger. Livia is about 13-14 and Sage is about 16-17. Sage is one of Rubens close friends, who creates weapons and likes to fight. She is only a minor. Livia on the other hard, doesn’t come in till a little later in the series, but she becomes a supporting character,. She’s very innocent, quiet and shy at first, but soon becomes brave and independent, and will go out of her way to help the people she loves.
