Fate / Stay Night part 2 (Blu-ray) (Japanese Animation)

From Sentai Filmworks! The Holy Grail War continues to escalate as a series of shocking revelations explain the history connecting Saber to Excalibur. As a massive wave of comas begins to take down the cities, it becomes clear that the only possible 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 in order to summon the Grail, Shiro is forced to choose between two equally lethal options: Let Saber’s mana continue at its existing level, certainly ensuring her death; or resupply her mana from his own magical circuit, reducing his power and leaving him open to magical attack.
