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...
Somehow, I feel like I finally 
made friends with Shonan's ocean.
بطريقة ما، أشعر وكأنّي شكّلتُ صداقة
أخيراً مع محيط شونان
Irgendwie habe ich das Gefühl, mich mit dem
Meer von Shonan angefreundet zu haben.
Siento que por fin me hice
amigo del mar de Shonan.
Siento que por fin me he hecho
amigo del mar de Shonan.
J’ai l’impression d’avoir enfin
apprivoisé la mer de Shônan.
Ho come l'impressione di aver finalmente
fatto amicizia con il mare di Shonan.
Acho que finalmente virei amigo do mar de Shonan.
Мне кажется, я наконец-то
подружился с морем Сёнана.
