Igarashi sends Tonbo, now a high schooler, to stay at a golf practice range in Kumamoto run by a friend who trains junior players. When Tonbo tries a driver shot for the first time, the other students are puzzled by her skill. She soon gets a chance to practice at a nearby course, where she meets Hinoki Otowa, a talented junior golfer known for her performance at the Kyushu Junior Championship.

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.
