Honkai: Star Rail was released globally on April 26, 2023, and serves as a narrative continuation of Honkai Impact 3rd. The game’s second major content expansion, known as Part 2, launched on February 29, 2024, adding new locations, characters, and storyline arcs.
On the other side of the collaboration, Fate/stay night: Unlimited Blade Works first aired on October 4, 2014, and features Rin Tohsaka as the central protagonist. The series spans two seasons with a total of 24 episodes, concluding with Emiya Shirou becoming Rin’s servant and the two departing to study in England.
During his time in England, Shirou becomes close to Luviagelita Edelfelt, a character affectionately referred to as “Guinevere” by fans.
With two beloved franchises crossing paths, fans of both Honkai: Star Rail and Fate/stay night can look forward to a unique and memorable collaboration event this summer.
