[Heizou seems perfectly cheerful, even as he idly studies his companion. His emotions are easy enough to read, and the frustration at being unable to find a familiar face in this crowd is completely understandable. And if he's as new to this world as Heizou is, then it's even moreso.]

Well, perhaps you'll have better luck finding them outside of this party. These masks seem to be affecting our ability to recognize even our closest friends. [Or maybe it's already common knowledge at this party.] Maybe you've seen them, but haven't seen them.

But to answer your question, I haven't been here for very long myself, so no, no one in particular. You could say I'm still getting familiar with the lay of the land, so I'm perfectly happy being able to speak to anyone if they're up for it! I don't suppose you have any insight for a newbie like me?
