Personally now that they've mention there is a day night cycle, and you bringing up a good point about the names.

I feel like the core concept of this game heavily, is dealing with duality in every way possible. Wether it be in the character designs Black vs White, the character names, the game's day and night cycle mechanics, fantasy vs reality, or the word versus in general XD I can't wait for more info so we can form more duality connections. It's really interesting!!!!

Also, I like the names. And that they have some significant meaning. Like they weren't given names because someone thought they sounded cool, they might actually be tied to the story
