The synopsis of episode 6, "Seeds of Hope," of the TBS Sunday Theatre drama "Diamonds Sleeping in the Sea" (Sundays at 9pm), starring actor Kamiki Ryunosuke, which will air on December 1st, has been released.
The story is set in 1963, the year before the Tokyo Olympics. While many coal mines are forced to close, New Year's Day comes as usual on Hashima Island. Meanwhile, Asako (Sugisaki Hana), who is enthusiastic about her activities in the gardening club, shows Teppei (Kamiki) the potted plants she has grown. Seeing Asako's joy, Teppei becomes happy. The two of them seem to be steadily getting closer.
Meanwhile, Kensho (Shimizu Hiroya) makes a decision and confides his feelings to Teppei alone. Meanwhile, Shinpei (Saito Takumi) and Rina (Ikeda Elaiza) visit the Araki family. The two have become closer since Reo (Kamiki, playing two roles) risked his life to save Lina from pursuers, and now they have come to deliver a message.
In the present day, Reo (Kamiki, playing two roles) learns that he and Izumi (Miyamoto Nobuko) are not related by blood, and that Izumi's real name is "Asako." In order to find out more about his relationship with Teppei, he begins to unravel the 10 diaries Teppei left behind. He then finds something like a "seed" tucked inside one of them... and so the story unfolds.
The drama is a story of love, friendship, and family spanning 70 years, set on Hashima Island (Gunkanjima) in Nagasaki Prefecture, which developed through coal mining from the beginning of the Meiji era to the postwar period of high economic growth, and in modern-day Tokyo. It is produced by the team behind the dramas "Unnatural" and "MIU404" (same series) and the film "The Last Mile," with screenwriter Nogi Akiko, director Tsukahara Ayuko, and producer Arai Junko.
