About once every sixty years, the spiritual power in the earth's veins will accumulate enough to support the birth of the Holy Grail, and then the Holy Grail will appear with the power to instantly realize any wish.
However, only a group of Masters and Servants can obtain this power. Therefore, an unwritten covenant was made, and the seven magicians, leading the heroic spirits summoned by each, fought for the ownership of the Holy Grail. The winner who survived in the end would obtain the ownership of the Holy Grail - this is the Holy Grail War.
The Sixth Holy Grail War is about to begin.
