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...
In that case, I'll make Kosuke-san 
understand me through my surfing!
في هذه الحالة، سأجعل كوسكي-سان
يفهمني من خلال ركوبي للأمواج
Dann werde ich Kosuke-san
beim Surfen beweisen,
En ese caso, haré que Kosuke
me entienda por medio del surf.
En ese caso, haré que Kosuke
me entienda por medio del surf.
E allora vedrò di farmi capire da Kosuke
attraverso il surf!
Sendo assim, vou fazer com
que o Kosuke-san me entenda pelo surfe!
Тогда пусть Коске поймёт,
каков я, через мой сёрфинг!
