This is a world where despair rules and people are turning into daemons right and left. But the one remaining guy who was deliberately created to easily turn into a daemon is like, nah, fuck that, I’ve gotta keep it together on the slim hope that Noctis will return.
He’s the one character in the game that gets to pick love over the destiny assigned at his birth. Even if he didn’t or couldn’t survive the daemon purge.
