Hikari Kohinata, affectionately known as 'Pikari,' is a girl raised along the Izu coastline who radiates warmth and energy throughout the series. Her boundless love for the ocean is matched only by her carefree, wholehearted nature—she often expresses her feelings through a signature whistle. Upon enrolling at Yumegaoka High School, she reaches out to the reserved transfer student Futaba Ohki, welcoming her into the diving club. With infectious enthusiasm and a surprisingly sharp eye for detail, Hikari guides her friends to uncover hidden wonders both beneath the waves and within the fabric of everyday life.
