Atlus Japan has registered several new websites as reported by Persona Central. They were registered by Ryu Office, a marketing company that has close ties with Atlus. They registered the sites dedicated to Persona 3 Dancing in Moonlight and Persona 5 Dancing in Starlight. Below are the following domains.
Most likely they are spin-off titles for the Persona 5 series. Persona 4 had two fighting game spin-offs, a dancing game, two animes, and an updated version for the title which released exclusively on the PlayStation Vita. Rumors believe that Persona 5 or it’s updated version will release on the Nintendo Switch following the announcement of Joker from Persona 5 in Super Smash Bros. Ultimate as DLC. I will report on it if it’s confirmed.
There was an announcement for a Persona 5 anime special: Dark Sun. It will expand on the conclusion of the anime that aired in 2018.
