Yuta is the administrator for Shirasu Wave, an app that offers information on wave conditions. Many surfers are grateful to him for his daily updates on the weather, wind, and waves in Shichirigahama. Yuta begins acting strangely, not eating all of his favorite shirasu, skipping practice, staying home from school, and stopping service for Shirasu Wave. Is he planning to quit surfing? Worried, Masaki searches for Yuta...
Joy enters the bloodstream...
...يدخل السّرور مجرى الدم
Das Glück schwimmt im Blut mit.
Una vez en el torrente sanguíneo,
Una vez en el torrente sanguíneo,
Quand il passe dans le sang,
La gioia entra nel flusso sanguigno e scorre
in tutto il corpo, dando vita a un nuovo potenziale...
Alegria passa a correr nas veias,
В кровь попадает счастье...
