Fate/stay night [Heaven’s Feel] III. spring song

The Holy Grail War has become dangerously distorted as Masters and Servants continue fighting for the wish-granting Grail. Shirou Emiya has chosen to protect Sakura Matou and refuses to ignore the truth surrounding her, even as she sinks deeper into darkness.

Shirou joins forces with Rin Tohsaka in an attempt to stop the war, while Illyasviel von Einzbern confronts knowledge that ties her closely to the conflict. At the same time, Zouken Matou continues using Sakura for his own ambitions. With the Grail War approaching its conclusion, Shirou's determination to save Sakura drives him into a final struggle against forces that threaten both her and everyone caught in the battle.
