While visiting a golf course on the island made by the residents, Igarashi witnesses Tonbo's incredible super shot. Intrigued by each other's golf skills, they decide to play together again the next day. While playing, Tonbo opens up about her love for the island. Returning at sunset, Gon encourages Igarashi to experience the island's starry sky, under which Tonbo reveals her past.

Igarashi heads to Kagoshima to find a young golfer who can match Tonbo, who refuses to leave the island. Despite visiting several ranges, no one measures up. On the ferry back, Igarashi learns from Yoko that her niece is a junior tournament winner. Excited, he arranges her visit to Hino Island. Days later, a pickup truck arrives by ferry, with the girl sleeping in the back.

Despite meeting for the first time, Tonbo and Tsubura hit it off and decided to play a round on the island's golf course. Tsubura is amazed by Tonbo's free-spirited style. However, Tsubura's own approach is methodical and precise, with calculated shots. Inspired by each other's contrasting styles, a competitive spirit grows within Tonbo, determined not to lose. How will their match turn out?

Though on the first day of the Kyushu Women’s Championship there were many players around Tonbo's age, she ended up paired with a housewife golfer named “Shima-san.” Her skills being just barely above the cutoff line irritates some fellow competitors. However, as the championship progresses, Shima-san’s unique approach to golf begins to influence her fellow competitors playing style!

Emma pushes through the pain of her injured leg for the sake of her swing, Hinoki battles her inner limits, and Tsubura stays true to her own style. Watching from the sidelines, Tonbo cheers them on. An intense showdown over a single final stroke builds to a thrilling, unexpected finish.
