Fate/Grand Order: First Order

In 2015, during the final era in which magecraft remained prevalent, the Chaldea Security Organization was established with the mission of preserving the continuity of human history. Chaldea monitors a world that magecraft could not observe and science could not fully measure, in an effort to prevent the inevitable extinction of humanity. However, one day, the future that Chaldea had been observing vanishes, and humanity's extinction in 2017 becomes inevitable—indeed, it has already occurred. The cause appears to be linked to Fuyuki, a provincial town in Japan, in the year 2004. In that year, an "unobservable region" emerges where none had existed before. Assuming that Fuyuki is responsible for humanity's extinction, Chaldea issues an order to explore, investigate, and possibly destroy this singularity—the quest for the Holy Grail, known as the Grand Order.
