The Iwatobi High School Swim Club is participating in a joint training camp with the Samezuka Academy and Soufuukan High School teams. Sousuke is also participating as an alumnus. In the midst of the excitement, Rei and Nagisa notice that something is odd about Romio's swimming. Then Shizuru tells them the story of what happened to Romio in middle school...
But the last day should be special.
لكن ينبغي أن يكون اليوم الأخير مميّزاً
Doch der letzte Tag
sollte etwas Besonderes sein.
Pero ese día debería ser especial.
Pero ese día debería ser especial.
Personne n’a une idée originale,
pour le dernier jour ?
Ma visto che si tratta dell'ultimo giorno, 
perché non facciamo qualcosa di diverso?
Mas deveria haver algo
legal no último dia.
Но последний день
должен быть особенным.
