It seems she isn't interested in Rating Games and is jsut using her peerage as a means of granting amnesty to those who are under suspicion or are mistrusted by the higher-ups such as Balberith, Verrine and Kuroka. Ruruko Nimura was allowed to become her Pawn due to Sona retiring from DxD to become the Head of Sitri due to her father falling into a coma, so she allowed some of the strong servants she meet recently like Ruruko, Rugal & Bennia to become members of individual DxD peerage's so they can fight with them.
