"Tonight I will appear in Nippon Budokan."

Today’s issue of Japanese newspaper Yomiuri Shimbun includes a surprise advertisement for Persona 5 and the Persona Super Live concert.

“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.”

To the right, we see the magic hat-wearing mask-thing and “Take Your Heart” text that appeared in the “News Flash! Persona Channel 2015” live stream earlier.

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.

Thanks, @Satohk1, @Yousei, @Sinopu, and so on.
