Después de perder su trabajo y su familia, Igarashi se encontraba sin esperanza. Su destino lo llevó a Hinoshima, conocida como "la última región inexplorada de Japón". Allí, se encuentra con Tonbo, la única estudiante de secundaria en la isla, y percibe extrañas señales de golf por todos lados. ¿Cuál es el secreto oculto detrás de los misterios de esta isla?

En el campo de golf construido por los habitantes de la isla, Igarashi queda sorprendido por los impresionantes tiros de Tonbo, mientras que ella admira la habilidad profesional de Igarashi. Los dos disfrutan del golf hasta el atardecer, momento en el cual Tonbo expresa sus sentimientos hacia la isla. Así se revela el pasado de Tonbo bajo el cielo estrellado de la noche.

As Igarashi adjusts to island life, he observes the interactions between Bunpei and Yoko. Golfing daily with Tonbo, he sees how the island has influenced her impressive shots. Inspired by her uninhibited style, Igarashi wants her to try tournament golf. However, he feels there's something unusual about her play. Unexpectedly, a squall hits them on the course.

Igarashi's unease with Tonbo's golf stems from the fact that she doesn’t feel the pressure that comes with a competition. On the island's cliff-top course, he sees his past failures with his son in her. Yet, Tonbo's actions make him reconsider, accepting her as she is. Learning from Yoko that Tonbo hates the idea of leaving, Igarashi realizes that a change in perspective, not location, is needed.

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?

The typhoon hit Hinojima directly. At the development center, Tonbo and Tsubura took refuge. Despite the power outage, Tsubura practiced her swings and shared her feelings. After the typhoon, she gifted her 5-wood to Tonbo. Igarashi then found plans for a hidden hole on the island's golf course and took Tonbo to play it.

Igarashi travels to Akureki to meet Mr. Kuta, the designer of the Hinonoshima golf course. He shares his past with Tonbo, who fears leaving the island. The next morning, Tonbo joins him willingly. Mr. Kuta warmly welcomes them and shows them a special one-hole course he created in the forest by a small pond.

The single-hole course designed by Mr. Kuta on Warizumajima Island, with its beautiful scenery, was a challenging monster hole. Igarashi struggles to conquer it, while Tonbo impresses with creative shots, though Mr. Kuta has doubts about her use of a 3-iron for putting.

Mr. Kuta asserts, "Tonbo's golf style won't work in competition," and takes Tonbo and Igarashi to a challenging practice green. As Tonbo tackles the monstrous green all day, she starts to appreciate the kindness of Igarashi and Mr. Kuta.

The children of the island had to write an essay titled "The Last Summer Vacation" at the end of their final middle school summer. After returning from Akurekijima, Tonbo expressed feelings for the island and new resolutions in essay. The islanders were surprised, and Igaiga worked hard to support her. By spring, at the graduation ceremony, Tonbo had grown taller, and hair reached her shoulders.

La decisión de Tonbo de abandonar la isla afecta tanto a los residentes locales como a los sentimientos del abuelo Gon, Wataru, Bunpei y Yoko. Mientras estas emociones se entrelazan, se organiza un torneo de despedida para Tonbo en el campo de golf de la isla. Solo queda un día hasta su partida

Tonbo decide dejar Hinoshima y, junto a Igarashi, aborda el ferry rumbo a Kagoshima. Durante el trayecto, ambos rememoran su vida en la isla desde que se conocieron. Gracias al golf con Igarashi, se abre un nuevo horizonte para Tonbo. Ahora que mira hacia el futuro, los habitantes de su amado hogar la observan y cuidan con cariño desde la distancia.

Para que Tonbo asista a la preparatoria, Igarashi la lleva a vivir con un conocido suyo en un campo de práctica de golf en Kumamoto. Al ver su swing con el driver, los demás aprendices dudan de las habilidades de Tonbo, pero pronto tiene la oportunidad de practicar en un campo cercano. Allí conoce a Hinoki Otoha, una talentosa golfista junior. ¿Podrá demostrar su verdadero potencial?

Tonbo y Hinoki recorren el campo de golf para practicar. Mientras Tonbo disfruta del juego con sus característicos tiros libres, la percepción de Hinoki sobre ella empieza a cambiar. En medio de la partida y bajo un fuerte viento, Igarashi llega al campo con un regalo inesperado para Tonbo. ¿Será de ayuda frente a su formidable oponente?

Después de observar de cerca el golf de Tonbo, el entrenador Hajime decide motivarla a competir en el Campeonato Femenino de Kyushu. Sin embargo, debe superar varios obstáculos para poder participar. Mientras comienza su nueva vida en la preparatoria, Tonbo divide su tiempo entre sus estudios y el golf para cumplir con los requisitos del torneo. ¿Podrá lograrlo a tiempo?

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!
