Time: Present Day.
Place: Fuyuki City; a seemingly ordinary midsize city in northern Japan.
Few people know the truth behind the secret history of Fuyuki City. Fewer still have directly participated in that secret history and lived to tell the tale. The end of the Fifth Grail War was thought to have ended the tale of that secret history as well, but now, fifteen years later, Fuyuki City’s ghosts once again begin to stir.
