The summer camp arc was a bit overall, since its resolution spilled over into the next volume. Yukino was hinted to have some terrible secrets herself, I wonder how this would affect the balance of their little club. Unlike Yui, who has more or less settle things with Hachiman and his lost opening ceremony, Yukino actually played a larger role in it that it appeared.
This was a good volume. The chapters were longer and paced very well.
