Nagato Yuki-chan no Shoushitsu: Owarenai Natsuyasumi

Haruhi is determined to squeeze everything possible out of summer vacation, dragging the Literature Club to a swimming pool where a race for exotic fruit is only the beginning of an exhausting schedule of seasonal fun. Kyon joins in until he realizes that the break has almost ended and he has not touched his summer homework.

With only two days left, the group gathers at Kyon's house for an emergency study session, complete with Asakura taking her role as teacher far too seriously. Kyon keeps finding excuses to play instead of work, and when everyone else finishes first, his final hope is a visit to Yuki and the very homework he should have done himself.
