In the year 2015, the last era of magic comes to an end. Caldea, an organization dedicated to monitoring the balance between magic and science, ensures humanity's survival for at least 100 more years. However, their predictions suddenly shift when the future they've been observing disappears, and they now believe humanity will cease to exist by 2017. The organization launches a Grand Order for a "Holy Grail Expedition" to investigate and possibly destroy the singularity responsible for this catastrophic event, which originated in Fuyuki, Japan in 2004.
