We also get another look at the mysterious girl we first saw in Chapters 102 and 104. It seems she, as well as Teru, plays a part in motivating Saki, but we have yet to see who she is or what impact she had on Saki.
It's also nice to see Saki making some headway against her opponents, even if her wins are small at the moment. I suspect that her victory will be the result of a direct hit on Kyouko, thereby dragging Himematsu out of second place.
