Fate/Grand Order is preparing to bring back its Fate/Samurai Remnant collaboration event on the Japanese server, with scheduled maintenance on October 14, 2026, ahead of the rerun.
The returning event, 復刻版:盈月剣風帖, revisits the collaboration inspired by Fate/Samurai Remnant, the action RPG developed by Omega Force and published by Koei Tecmo.
Alongside preparations for the event, the maintenance will introduce interface adjustments and fixes to issues involving transformation camera behavior.
Players on Android and iOS will also need to update their game clients to version 2.139.5 after maintenance.
The announcement applies specifically to the Japanese version of Fate/Grand Order. It does not establish a rerun date for the English-language server.
Samurai Remnant Collaboration Returns to Fate/Grand Order
The collaboration rerun revisits 盈月剣風帖, an event connecting Fate/Grand Order with the world of Fate/Samurai Remnant.
Originally released in 2023, Fate/Samurai Remnant follows Miyamoto Iori and his Servant, Saber, through a Holy Grail conflict set in Edo-period Japan.
The collaboration brings that setting into Fate/Grand Order, giving players another opportunity to experience the crossover's story and characters.
However, the October 13 maintenance briefing does not establish the rerun's complete reward list, summon lineup, or closing date. Those details should be taken from the dedicated event announcement rather than inferred from its previous run.
October 14 Maintenance Includes Bug Fixes and UI Changes
The maintenance announcement identifies three main areas of work: preparing the collaboration rerun, making interface adjustments, and correcting transformation-camera issues.
Players should expect a client update following the maintenance, with both supported mobile platforms moving to version 2.139.5.
Fate/Grand Order Japan: October 14 Update
| Server | Japan |
|---|---|
| Maintenance date | October 14, 2026 |
| Collaboration | 復刻版:盈月剣風帖 |
| Required app version | 2.139.5 |
| Additional changes | UI adjustments and transformation-camera fixes |
The available briefing does not specify the maintenance start and end times, so players should consult the Japanese announcement before planning around server downtime.
What About the English Version?
The October 14 maintenance concerns Japan's Fate/Grand Order service.
Although the English-language version has previously received content originating from Japan, its event schedule is managed separately.
There is currently no English-server date established by this announcement for the Samurai Remnant rerun.
For Japanese-server players, the immediate priority is ensuring that their device can install version 2.139.5 when the update becomes available.
The collaboration's detailed schedule, rewards, and participation requirements should be checked against the dedicated event information.
