The United Nations, often shortened to UN, is an important political entity in the Guilty Gear series. It was established in 1945 after World War II and continued to exist into the 22nd century.
Its existence became pivotal during the Crusades since it established the primary force that battled the Gears, the Sacred Order of Holy Knights and entrusted the Outrage pieces to the organization. It is unknown how the UN acquired the weapons, which were created by Frederick Bulsara.
Since the war decimated many nations such as Japan, the UN handled all the stateless areas. The UN is also responsible for the International Police Force and the Post-War Administration Bureau, whose tasks include regulating technology and keeping the population safe from the threat of Gears. In Guilty Gear Judgment, the UN declared an international emergency because of the outbreak of monsters in Viltania and issued a bounty to whoever could restore peace. Likewise, the UN also issued the 500,000 World Dollar bounty on Dizzy.
Prior to the events of Guilty Gear 2 -Overture-, it is stated in Ky Kiske's short story that the UN divided Europe into three entities and established them as the United Kingdom of Illyria. The UN then issued an election for the position of the king which Ky won by popular vote. However, according to an interview, Ky was appointed secretly so that he would lose the ability to exhort those who were above him. It is also confirmed in Ky's short story that he was coerced into cooperation as the UN knows about his wife.
