“Advance notice: Tonight I will appear in Nippon Budokan,” the advertisement reads. It’s signed, “The Phantom.”
Nippon Budokan is, of course, the venue of the concert.
In the center of the advert, we see a character wearing a white mask. We’re not sure who he is, but given the previous concert teaser visual, it’s likely the protagonist of Persona 5.
In the lower left corner, we see the text, “Persona 5 begins.”
The Persona live stream is still ongoing. Another unannounced event is planned for 10:30 p.m. EST tonight, and a final unannounced event (heaviy suggested to be Persona 5-related) is planned for tomorrow morning after 7:00 a.m. EST.
