Fate/stay night Movie: Heaven's Feel - II. Lost Butterfly

The Holy Grail War in Fuyuki grows darker as Servants and participants disappear in ways that no longer resemble the conflict's known rules. Shirou Emiya continues fighting even after losing his own Servant, while his bond with Sakura Matou becomes increasingly important as the war begins leaving visible marks on both her and the city.

A mysterious Shadow consumes everything it reaches, and secrets surrounding the Matou family and Sakura's old connection to the Grail War begin to surface. Shirou insists on protecting the person in front of him even when that clashes with his old ideal of saving everyone. As Rin, Sakura, Zouken, and the remaining Servants are drawn deeper into the crisis, the dream of becoming a hero of justice starts to fracture around a harsher question: what if saving one person means abandoning others?
