The Holy Grail War continues to escalate as a series of shocking revelations provide an explanation for the history connecting Saber to Excalibur. In a lethal game of chess, pawns and knights are expended one after the other, slowly whittling down the number of surviving players. And as a massive wave of comas begins to take down the cities, it becomes clear that the only imaginable path to victory is an assault on the Master and Servants of the Ryudoji Shrine! But when Sakura is taken with the intention of sacrificing her with the intention to summon the Grail, Shiro is forced to choose from two equally lethal options. Does he let Saber’s mana continue at its existing level, almost without a doubt insuring her death as the battle wages on? Or will have to he resupply her mana from his own magical circuit, reducing his power below that of the other Magus, and leaving either one of them open to magical attack? The cost of winning could mean potentially losing the whole lot in the climactic conclusion of FATE/STAY NIGHT!
