A week after coming to the island, Handa is trying to focus on improving his calligraphy. However, he keeps getting interrupted by Naru and her friends, including middle-school girls Miwa and Tama, who want their old base back!

Handa's only friend, Kawafuji, arrives with a kid named Kanzaki Kousuke in tow, but their trip to Handa's house ends up being very roundabout. Why does Kousuke want to meet Handa so badly, and why did Kawafuji agree to bring him?

After Handa submits his "Star" calligraphy despite some trepidation, he gets roped into helping to build a stone wall and then into taking the girls to the summer festival. Meanwhile, Kawafuji gets the exhibition hall director to agree to welcome Handa back to Tokyo. How will he bid farewell to the kind islanders who've taught him so much?

With his calligraphy exhibition entry finished, Handa wants to return to the island and the people he cares about there. Unfortunately, his mom is dead set against it. How will he convince her to let him go?
