Fate Purification

Following the Fate Stay Night UBW line, the event is still in Fuyuki City, but this time Fuyuki City is located two kilometers underground in London. The Clock Tower specially appointed El-Melloi II to organize this Holy Grail War, and the magicians invited were all children of aristocratic families who had a close relationship with the Clock Tower. However, due to some reasons, the beginning and end of this war has not been officially recognized, and naturally it cannot be regarded as the Sixth Holy Grail War. At the same time, some external forces are secretly lurking in it, and coupled with internal competition, I believe this Holy Grail War will be very interesting.
