After witnessing Tonbo's golfing style up close, Coach Hajime is determined to unlock her potential by entering her in the Kyushu Women's Championship. However, she must meet the eligibility criteria first. As Tonbo starts her new high school life, things get hectic as she learns to juggle school, going to the practice range, and practicing on the golf course to secure her spot in the tournament.

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!

Tonbo joins her first tournament, playing with a bold, freewheeling golf style that puts her in the lead on day one. On the second day, she's paired with the other top players from the first round: Hinoki, Tsubura, and Ema, who placed second. With Ema fighting for a comeback after a rough past, their group’s round ignites from the very first hole!

After competing in the Kyushu Women’s Championship, Tonbo travels to Hinoshima with Igarashi to report the results. Together, they reflect on their new challenges in Kumamoto. Along the way, they recall the people who supported Tonbo and the rivals she faced in her first tournament, each with their own aspirations. Tonbo's journey through golf continues to soar—unstoppable and full of promise.
