So after Noct Gar, I head cannon Noct and Prompto picking dorky as hell names that they use when gamming online.
And 100% when getting a high score on a game at the arcade they left weird initals or names on the high score board.
There should have been a cutscene showing Noct putting a dorky name in on the Justice Monster five game.
I will accept this as nothing less than cannon.
ETA: Square Enix would have my soul if they put something after their done playing JM5 with Ignis doing a heavy sigh and eyeroll saying something along the lines of “Well, at least they aren’t leaving behind a trail of our whereabouts for the Empire.”
Because you know safety first children.
