The event has been announced only for Japan at the moment, which is normal since the Japanese version of the game is ahead compared to the western one. That being said, it should come in English at some point down the line.
It’ll start in Japan on September 9, 2022, and it’ll include its own quest and three playable characters from Persona 5 Royal, Joker, Queen, and Fox.
Update: Square Enix revealed that the event will actually happen at the same time on the global servers. It’ll launch on September 8 Pacific Time.
