Atlus has been busy producing a range of spin-off titles and projects related to Persona 5, much like it did with its prior title, Persona 4. These have included collaborations with mobile games, a re-release in the form of Persona 5 Royal, and the recent announcement of Persona 5: The Phantom X, a mobile/PC exclusive title by Black Wings and Perfect World Games. While the latter is currently only available in China, the registration of a new domain name, "P5T.JP," near the end of May suggests that another project related to Persona 5 could be on the horizon. Although the site is currently inactive, the recent update could indicate that Atlus is gearing up for an official unveiling soon.
The recent update to the "P5T" domain follows a pattern seen in previous updates to Persona 5-related media and games, where the website is moved from the Japanese domain registrar nameservers to Atlus' own nameservers. This change has historically signaled an impending official announcement, with past reveals typically happening within two weeks of the update. Persona Q2's domain, for example, was moved to Atlus' nameservers shortly before the game's official announcement at a Persona music concert. Similarly, Persona 5 Royal and Persona 5 Strikers were teased shortly after their nameservers were changed. With upcoming events like Summer Game Fest 2023 and the Xbox Games Showcase just days away, it is possible that Atlus will use these platforms to unveil more information about the mysterious P5T project.
There is speculation that the new spin-off game in the franchise could be related to Persona 5: The Phantom X mobile spin-off. One theory suggests that this game could potentially be the international title for P5X, which currently does not have its own domain. Persona 5 Tactics has been suggested as a possible title if the game is released outside of China. However, it is important to note that these are just rumors and speculation, and fans should wait for official announcements before getting too excited.
