Fate/stay night [Unlimited Blade Works] Season 2

During the Fifth Holy Grail War, Caster makes her move by seizing Shirou Emiya’s Servant, Saber, tightening her grip as her power continues to swell. Recognizing the danger, Rin Tohsaka and Archer decide she must be confronted immediately—yet the war’s shifting alliances and pressures begin to pull Masters and Servants onto diverging paths.

Even after losing his Servant and fighting through serious injuries, Shirou refuses Rin’s insistence to withdraw from the conflict and throws himself back into the struggle against Caster. As battles escalate and the city is drawn deeper into violence, the true aims of the competing Masters and Servants gradually come into focus, each willing to risk everything for a chance to claim the Holy Grail.
