One question received from a fan says that there was a lot of downloadable content in the original Persona 5, and that they were glad that everyone in the Phantom Thieves could have their outfits changed. In turn, they’re asking if Kasumi Yoshizawa—the new character—will have her own versions of existing DLC added, and that they love the maid outfits in particular and would be glad if she could also wear one.
Atlus answers that there will be new costumes in Persona 5 Royal, and that information on the additional content will be given in the near future. Additionally, Kasumi Yoshizawa will indeed have her own versions of the Persona 5 DLC costumes.
This new screenshot for Kasumi in her maid costume was shared:
Stated in a previously released FAQ for Persona 5 Royal, the DLC purchased for either the Japanese PS3 or PS4 versions of Persona 5 will be able to be used in Persona 5 Royal, needing to be repurchased at a “1 content for 10 yen” rate.
Persona 5 Royal will be released on The PS4 in Japan on October 31, 2019. It will be released in the West in Spring 2020, with a general 2020 release in Asia.
