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...
The kind of big waves you like 
come when they come!
الأمواج الكبيرة التي تحبّها تأتي عندما يحين وقتها
Die großen Wellen, die du magst,
kommen auch, wenn sie lustig sind.
También hay olas grandes
como las que te gustan.
También hay olas grandes
de las que te gustan.
Tu seras servi en grosses vagues
du jour au lendemain.
Le onde alte che tanto adori
arrivano quando devono arrivare!
As ondas grandes de que você
gosta vêm quando vêm!
Когда надо, бывают
и твои любимые крупные!
