The film was first announced on September 21, 2016 when the finale of the anime's fourth season, Fate/kaleid liner Prisma Illya 3rei aired. Shin Oonuma and Silver Link returned from the anime series to direct and produce the film, respectively.^[2] Singer ChouCho performed two theme songs that are played in the film's ending primarily centered around Shirou's actions and his bonding with Miyu.

Sentai Filmworks released the film's Blu-ray in English regions during July 2020. Critical reception to the film has been positive for its handling of an alternate take of Shirou and his battles in the Grail War while also highlighting the visuals produced in general.
