During episode 11 of Persona Stalker Club, what seems to be the official logo for the Persona Super Live 2015 concert was revealed in a promotional video for it.
The logo—that of a dagger casting a large shadow in front of it—could be depicting a theme of the concert and, potentially, Persona 5, which will presumably be featured at the event on February 5th, 2015.
