This drama is set on the automobile transport ship 'Ampitrite' during its voyage, featuring Marlin Sakamoto (Marie Iitoyo), a budding third officer, and Tsubaki Ishikawa (Rena Takeda), also a budding third engineer. They confront various troubles, including clashes with their strict superiors, unreasonable transfers, bad weather, and encounters with pirate ships, all in a cute and comical way as they aspire to become fully-fledged sailors in this 'sea work comedy.' As for the male cast, Yuta Hiraoka has been cast as Takuya Kanzaki, the 'Demon Chosser' (first officer) who is on board the Ampitrite and strictly mentors the junior officers like Marlin. Akihito Miyazaki will play Hikaru Kisaragi, a shy and dog-like junior engineer who secretly harbors romantic feelings for Marlin, whom he refers to as 'Sakamoto-senpai.' Additionally, Katsumi Mizuno from BOYS AND MEN, who will perform the theme song 'Flame: Taking the World,' has been cast as Shusaku Harumi, a second officer and self-proclaimed muscle enthusiast who serves as a mood maker and is close in age to Marlin.
