"... I've never been to New York. I'm from Tatsumi Port Island, in Japan." How to explain this... "Shadows re monsters. I think they're from people? I'm not totally sure how. But most people aren't awake during the Dark Hour, which happens when the clock strikes midnight. That's when Shadows come out and that's when we do most of our stuff. Things that aren't Persona - parts of ourselves that we summon in order to fight - have a hard time taking down a Shadow."
