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...
