One day, Japan metastasized to another world. Japan, which has a low food self-sufficiency rate and relies on imports from other countries, faces a food shortage. The Japanese government immediately declared a state of emergency to prevent the people from starving. The Japan Air Self-Defense Force will search the area and discover the 'Lodenius' about 1,000 km southwest of the site. Japan got out of a predicament by concluding diplomatic relations with 'Duchy of Kwa'a-Toine' 'Kingdom of Quila' which existed in the continent. For a brief moment, another hegemonic state on the continent 'Kingdom of Lauria' declared war on 'Duchy of Kwa'a-Toine' 'Kingdom of Quila'. How will Japan react to the crisis coming again? What is the fate of national survival for survival?
