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...
Seems like today's the day I'll be able 
to have fun riding some waves!
يبدو أنّ اليوم سيكون اليوم الذي أستطيع
!فيه التمتّع بركوب بعض الأمواج
Heute werde ich sicher gut surfen können!
¡Parece que por fin
podré montar algunas!
¡Parece que por fin
voy a poder montar algunas!
Ça annonce
une bonne session, aujourd’hui.
Sembra che oggi sia il giorno buono per godermele!
Parece que hoje vou conseguir
me divertir com umas ondas!
Похоже, сегодня удастся покатать!
