   The Fourth Holy Grail War.
   In most timelines, The Japanese city, Fuyuki, a secret magical tournament is held, where seven mages known as "Masters" summon "Servants", reincarnations of legendary heroes from all across time, to fight in a deadly battle royale where the winner obtains the Holy Grail, an omnipotent wish granter.... bringing nothing but ruin

   In this timeline, unbeknownst to the mages participating in the ritual, someone is about to alter the course of their destiny.
