Netsuretsu teki chuuka hanten

The Star Leo is a luxury cruiser shuttling between Japan and Hong Kong. On this cruise, seven top chefs known as "culinary kings" have been invited for a major event in which guests can savor a fancy dinner that they cook up. This event was planned by Shiori Tachibana, a woman who learned business management in Hong Kong. But the restaurant chefs "Heiheiro" aboard the luxury ship left in protest against the event, and to make matters worse, due to a certain slip-up, the "culinary kings" also failed to board the ship, which then set sail for Japan without them. Tachibana gets the cooperation of the "loser" chef remaining in the restaurant together with their apprentice chef, crewmembers and passengers for a team of five people to take on the cooking for the event. What will the voyage of the Star Leo turn out to be?
