In the world there is a division between team and individual sports. Following this system, the game of two teams on a sand court divided by a high net was born, called beach volleyball. The most widespread and official variant of competition is the "two‑on‑two" format. One fine day, Haruka flew to Okinawa to visit her cousin Kanata and unexpectedly plunged headfirst into the world of this game. She even formed a team with her at a time when Kanata had become completely despondent and decided to give up because of her short stature. Just one choice: an indispensable partner. Only two participants on each side of the net on scorching sun‑soaked sand. Now their goal is the junior tournament!
