Fate/Zero Season 2

The Fourth Holy Grail War continues with no clear winner, but an emerging danger forces the surviving Masters and Servants to consider cooperation. Church supervisor Risei Kotomine calls on them to confront a threat powerful enough to disrupt the war itself and potentially destroy Fuyuki City. Their temporary alliance is fragile, and individual ambitions soon begin tearing it apart.

At the same time, the partnership between Kiritsugu Emiya and his Servant, Saber, grows increasingly strained by their incompatible views of heroism and chivalry. Elsewhere, Kirei Kotomine continues searching for meaning in his own life as he forms a troubling connection with another Servant. As the Grail War moves toward its conclusion, the remaining participants become increasingly willing to cross moral lines in pursuit of victory.
