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.

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!

The night before the tournament’s final day, Igarashi arrives in Kumamoto. Noticing a change in Tonbo, he offers advice to draw out her strengths.On the last day, Tonbo, with her trainee caddie Nishida, faces challenging, windy conditions. Skillfully using the wind to her advantage, she climbs the leaderboard, making Hinoki, Tsubura, and Ema recognize her as a serious rival for the title.
