I can maybe see Le fay becoming Issei's pawn (I would guess at a value of about 2) but I imagine that Yasaka, Kunou, Bennia and Tiamat wont ever join. Yasaka and Kunou are important political figures for the youkai, Tiamat is involved in the rating games and Bennia is Sona's knight and since he already traded 4 of his pieces. I could see Tiamat becoming his familiar since that was mentioned in volume 4. If older characters are joining his peerage I think its possible Kiyome Abe will join since Christe was mentioned in the latest volume or perhaps Aika since she is developing magical powers.
