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

The Fifth Holy Grail War presses on as Fuyuki City slips further into turmoil. Shirou Emiya remains committed to his ideal of becoming a hero of justice, but a mysterious dark shadow and its string of killings force him to confront a threat that doesn’t fit the war’s usual rules. Determined to uncover what’s behind the murders, Shirou pursues the truth while the stakes rise for every Master and Servant still standing.

At the same time, Shinji Matou advances his own schemes, using his sister Sakura to corner Shirou. Shirou and Rin Tohsaka move against Shinji in an effort to free Sakura from his abuse, only for long-buried secrets within the Matou family to come to light. As the city’s darkness deepens, the Holy Grail War itself begins to feel increasingly unstable.
