The Blue Lock × REMATCH collaboration ends on October 23. The closing reminder published on October 20 highlights the temporary Aura Striker mode and urges players to obtain the Isagi, Nagi, Bachira and Rin bundles before their withdrawal.
For anyone who has postponed taking part, the practical consequence is a limited window to play the mode or obtain a bundle. Those are different reasons to return to the event: experiencing its gameplay and choosing character content each involve something whose availability is temporary.
Aura Striker is a temporary seasonal mode
In its official Steam announcement, the team describes Aura Striker as a temporary mode for the current season. Players interested in trying it should therefore plan around the collaboration’s closing date, rather than assume it will remain part of the available modes afterward.
The seasonal framing matters here. Aura Striker is presented as an opportunity tied to this event, so putting off a session also risks missing the mode during its announced run. For players whose interest is primarily in playing it, the relevant action is to make time for a match before the collaboration closes.
Isagi, Nagi, Bachira and Rin bundles face withdrawal
The reminder also names the Isagi, Nagi, Bachira and Rin bundles and encourages players to obtain them before they leave. Anyone interested in one of those characters has a separate choice to make about the corresponding bundle during the event’s availability.
The announcement concerns the opportunity to obtain those bundles. It should not be read as notice that content already obtained will be taken away. That distinction matters for existing owners: the end of an offer and the removal of something from an account are different claims.

October 23 comes without a cutoff time
No closing hour or time zone accompanies the announced date. October 23 therefore should not be treated as a promise that the collaboration will remain accessible until midnight in a player’s local time. Scheduling a final session around that assumption could mean arriving after the event has closed.
If you want to play Aura Striker or obtain one of the named bundles, leave room before the closing day. The reminder establishes an upcoming withdrawal; it does not establish whether the Blue Lock content will return later.
