I bet you guys kiba's friend, tosuka, will become rias's new rook. I say this because of two reason because of how useful she would be as rook with her strong barrier type sacred gear(hope we get a name for it soon), which would make her good at defense like how rosswessie was with her defense magic, and because as rias's rook she would be able to send more time with kiba, rias's knight. What do you guys think?
