"I'm so gonna kink shame you if that's what you're into," he says, trying to cover up his yawn.

But he knows Prompto knows he's fighting sleep at this point. They've spent enough time together by now that Prompto can easily tell when he's minutes from sleep. Ignis and Gladio can tell, too. The power of Lucian kings is draining, even here in Nippon, but he doesn't feel it as strongly as he did back home, probably due to the fact that the Crystal isn't here with them... That doesn't stop him from thinking about it, though, his mind drifting back to his dream, their own world, what awaits him when if he is ever able to return.

Noctis yawns again, "You need to get some sleep too, Prom. You've been up as long as I have."
