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...
I see. Yeah, he's my little brother.
هكذا إذاً. أجل، إنه أخي الصغير
Ach so. Ja, er ist mein kleiner Bruder.
Ya veo. Es mi hermano.
Ya veo. Es mi hermano.
D’accord.
Ouais, c’est mon petit frère.
Ah sì?
Entendo. Mas sim,
ele é o meu irmão caçula.
Ясно. Да. Это мой младший брат.
