Ya I thought of that. Isn't their two of rooks, knights and bishops. She said it is already her full set then that must mean Koneko and Kiba must have taken two each and one bishop is already been made off screen
no, kiba and koneko only took 1 each. the last bishop, or the mutating piece, was taken at about the same time as koneko, i think. it is given to a half vampire. the knight will be given to a holy sword user after the battle of Excalibur , and the rook will be given to a valkyrie after the battle of Ragnarok.
