Seiya brings a young foreigner named Shiketa, whom he met at a certain teishoku restaurant, to the office. Shiketa is looking for a Japanese dish that is “pudgy and a little hard". Ryosuke and Kyoko look up the dish on their computer and deduce that it is stewed pork cubes. After making various flavored pork stews and having them taste them, it became clear that Shiketa was looking for a Japanese-flavored pork stew with a strange chewy texture. At the same time, Chief Yamauchi is visited by Raymond, a consular official from an oil-producing country, who asks him to urgently look for a prince who is apparently in Yokohama on a private visit to Japan. According to the story, the prince, who is the next king of Japan, has some disturbing activities around him that are aimed at his life. Momo and Igarashi, who were told that the prince is a top secret and given his portrait, immediately set out to search for him.
