"Oh right, almost forgot," Nagito said as he sheepishly rubbed the back of his head. He turned to Joey, "Right. I mentioned something earlier about things called Shadows? Well they're like the embodiment of negative human emotions that try to eat your psyche. A bunch are right outside, so you'll probably get to meet 'em soon enough. To battle these guys, we use Personas."

He gestured to Karna, Pixie, Kurama Tengu, and Alice - the 4 Persona currently standing idly by. "Long story short, they're like Shadows since they're basically made of our emotions and inner psyches and all that psychological crap, but they're 'tame', I guess you could say."

Nagito had a coy grin on his face as if he was planning something mischievous. "Speaking of which, let me show you something cool..." 

And with a quick speed, Nagito's Evoker was in his hands, directly pointed at Joey's head. Due to their close proximity, there was probably no way he could've missed unintentionally if it were a real gun, which, for all Joey would know, it was.

Nagito pulled the trigger.
