SPY×FAMILY
Everyone has a part of themselves they cannot show to anyone else. At a time when all nations of the world were involved in a fierce war of information happening behind closed doors, Ostania and Westalis had been in a state of cold war against one another for decades. The Westalis Intelligence Services' Eastern-Focused Division (WISE) sends their most talented spy, "Twilight," on a top-secret mission to investigate the movements of Donovan Desmond, the chairman of Ostania's National Unity Party, who is threatening peace efforts between the two nations.
