The “Tokugawa Restoration Labyrinth, Ooku” limited-time event first appeared in the game’s Japanese version in 2019. The event first appeared in the game’s English version in 2021.
The game’s English website describes the event’s story:
Headquarters has fallen eerily silent, now almost empty following an attack from the outside. Master is called urgently to the Control Room, and along with the single Servant who managed to escape harm, Rayshifts to determine the cause.
They arrive in mid-seventeenth century Japan—the Edo Period. In the deepest reaches of Edo Castle, the epicenter of the issue, the silent abnormality still grows. The castle’s Ooku, a realm detached from the rest of the world, has transformed into a bottomless labyrinth brimming with sinister mystery. The party roams the endless paths of the luxurious osuzurouka, the ‘corridor of bells,’ in search of an exit.
Aniplex released the Fate/Grand Order mobile game in Japan in summer 2015. The game received an English release in the United States and Canada in June 2017.
The game inspired the Fate/Grand Order Absolute Demonic Front: Babylonia television anime in October 2019, and the two-part Fate/Grand Order The Movie Divine Realm of the Round Table: Camelot films in 2020 and 2021, respectively.
