On four islands, three of them 'deserted' by Nagisas words... and with a 1 km distance between each island, the Iwatobi swimming team is staying for summer camp. Rei and Nagisa have a tent on the beach, and so do Haruka and Makoto.. While teacher and Gō found a lounge and are staying indoors! So unfair. But it's fun for Nagisa either way!

Once swimming practice came to an end, Nagisa forcefully dragged Rei to go on a walk with him around the beach. He swings their hands back and forth, bouncing and jumping as he walks.

"You're getting better at swimming, ya know?" Nagisa hums proudly, pulling Rei closer to him with a forceful pull of their conjoined hands.
