I guess old habits die hard, huh?
After reading this chapter, I guess it's pretty clear now that Saki wasn't consciously acting to eliminate Miyamori and Esui. It was all done so that she could get a final score of +/- 0. The remaining question now is whether she aims for that score consciously or otherwise. After all, I don't think she's the kind of person that would flaunt her skill needlessly in front of everyone.
What would Teru say when she looks at this match's record?
