Seven Knights Re:BIRTH And Demon Slayer Crossover Runs From October 1
The crossover hands the RPG a limited four-week window built around the two Kamado siblings rather than a broad roster, with Tanjiro as a login gift and Nezuko gated behind play.

Seven Knights Re:BIRTH is running a Demon Slayer collaboration for four weeks, from Thursday, October 1 to Thursday, October 29. Pre-registration opened Monday, September 14 through the collaboration special page, and everyone who registers gets 10 Demon Slayer Summon Tickets. Tanjiro Kamado is the first-day login reward and can be raised up to awakening by playing, while Nezuko Kamado appears as a Legendary Pet obtainable during the event period.
The pre-registration window and the event window do not open at the same time. Registration runs from Monday, September 14, while the collaboration itself starts Thursday, October 1 and closes Thursday, October 29, four weeks later.
The two Kamado siblings are handled differently in-game. Tanjiro Kamado arrives as a gift reward for logging in on the first day of the event period, and can be raised up to awakening by playing. Nezuko Kamado appears as a Legendary Pet and is obtained by playing during the event period.
