Masaki is living a regular high school life in Shonan while staying at the home of legendary board shaper Tadao. In the early mornings, he goes out to ride the waves with Kosuke and Yuta. Then, he goes to school. After classes, he goes back to the beach. Day after day, he lives a life of contentment, immersed in surfing. Amidst all of this, little things that Masaki does pile up, angering Kosuke. Unable to let go of his indignation, Kosuke challenges Masaki to a surfing match...
"I'm not sick with missing home. 
I'm missing Oarai's waves!"
"لستُ أفتقد للمنزل. أفتقد أمواج أواراي"
Heimweh? Ich hab Wellenweh nach Oarai.
Más que extrañar mi casa,
extraño las olas de Oarai.
Más que echar de menos mi casa,
echo de menos las olas de Oarai.
« Pas vraiment,
plutôt le mal des vagues d’Ôarai. »
"Non mi manca casa, mi mancano le onde di Oarai!"
Não estou com saudade de casa,
estou com saudade das ondas de Oarai!
«Тоскую, но не по дому,
а по волнам Оарая».
