Prefecturals are over and the Iwatobi Swim Club members are pleased by the progress they have made.  A local summer festival gives them an opportunity to relax.  When Nagisa finds out that Rin is also at the festival, he orders Rei to follow Rin and make sure that Haruka and Rin do not meet.

на улице 39 градусов?
