On July 11, 2004, World War III broke out, intensifying the Cold War and destroying trust between individuals and nations alike. The reason it ended was never made public. It was a war with no winners. On February 28, 2021, the universe from another plane invaded. Humanity's already fractured military forces were no match for their ruthless opponents. Then a woman named Kasugano Ai led her troops to successfully repel the invaders. Driving them back may not have been the most important result of this interplanar war. The most important outcome was that ordinary people learned supernatural abilities existed, and that vampires, monsters, psychics, and others like them were collectively known as the supernaturally gifted.
