Worldview Fun even if you don't know it
The world is currently in the midst of a large-scale war between the Ligiro camp and the Fasces camp. The Ligiro camp, consisting of the Alliance Nations, the Queen's Kingdom, the Liberte Republic, the Republic of Sinrat, and the Union of Krasnaya Socialist Republics, has formed a united front to block the expansion of the Fasces camp. In contrast, the Fasces camp is a military alliance centered around the Waltz Empire, the Miyabi Empire, and the Verde Kingdom, continuing to invade various regions using their powerful military force and controlled systems as weapons. Magic also exists in this world and is used in a wide range of fields such as military, medical, communication, and industry. In particular, high-level mages are often treated as strategic weapon-class forces, and competition for magical research and supernatural weapon development is intensifying between nations. Furthermore, there exist national strategic-class personnel called "Last Resorts." They are the "final trump cards" who support the nation not only through overwhelming combat ability but also in various fields such as information warfare, intelligence, and politics. Nations are engaged in fierce management and competition over them.

-What is a Last Resort?-
"Last Resort" is a general term for the final trump card a nation deploys. The etymology is literally "Last Resort." Today, it is treated as a title referring to "national strategic-class personnel," including those in information warfare, intelligence, politics, and technological development. The selection criteria are not limited to simple combat power. Those with overwhelming military force or supernatural abilities are obvious candidates, but those who excel in national management or information manipulation can also become a Last Resort. Therefore, their nature varies greatly by country; some are feared as "monsters," while others function as the "brain of the nation." Additionally, previous generations of Last Resorts exist in each country, and their fates vary. Some live as heroes, some are imprisoned, and some are erased from history—the treatment differs by nation.
