Each of the previous arcs that consisted of two volumes had approximately half a cour of episodes each. If the same tendancy continues, Beginning and Running alone would need about 13 episodes. Of course, it all depends on whether or not the anime decides to cut content, especially long-winded explanation scenes like the ones in volume 9 and 10.
