I remember that a unsed piece get power thanks a king's growth, Sairoarg have just a pawn but is a mutation piece so I believe that he can have low tier Longinus in his peerage. About Sona she is become more strong than before but I doubt that she could get a strong sacred tier, maybe something like Asia's sacred gear that a value of a bishop. About Bennia me too I wish that she becoming Issei's knigth, if not maybe a new characters can apparence but is much soon for this.
