Tonbo!

Igarashi hits rock bottom as he loses his family and his job. He flees society on a ferry to Hinoshima - “Japan’s last hidden paradise.” There, he meets Tonbo, the islands only middleschooler. As Igarashi explores the remote island, he senses something odd—a pervasive golf theme, despite no golf course or known golfers on the island. What secrets does this golf-enveloped, mysterious island hold?

Tonbo impresses seasoned golfer Igarashi with her unique style, playing solely with a 3-iron. Intrigued, Igarashi adapts his wedge with her 3-irons grip and coaches her on its use. Teaching Tonbo reminds him of instructing his son, Rintaro, evoking regrets about robbing Rintaro of golfs joy.

Igarashis unease with Tonbos golf stems from the fact that she doesn’t feel the pressure that comes with a competition. On the islands cliff-top course, he sees his past failures with his son in her. Yet, Tonbos 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.

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

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.

Mr. Kuta asserts, "Tonbos golf style wont 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.

Tonbo decided to leave the island, which greatly impacted the residents of the surrounding islands. Amidst the mixed emotions, a farewell golf tournament was held, with just one day left until departure.
