Both series stream on the ABEMA Anime SPECIAL channel. The press release notes that ABEMA celebrated its 10th anniversary on April 11, 2026, and positions itself as "the new future of TV." The service broadcasts about 25 channels across news, original dramas, reality shows, variety, anime, and sports. It claims the highest number of original episodes among domestic video services in Japan as of March 2026, per its own count.
The marathon is part of ABEMA's 10th anniversary programming, which includes the "ABEMA 10th Anniversary Free Great Thanksgiving Festival" and other special broadcasts throughout the year. The Fate series began with TYPE-MOON's game Fate/stay night and has expanded into anime, movies, and games. The press release describes the series as centering on the Holy Grail War, "where mages (Masters) and heroic spirits (Servants) engage in battle over the 'Holy Grail,' a wish-granting device that fulfills any wish."
