>>32715162The Japanese liked the name You and Mizuki, because they were Japanese names and easier to use than Sun and Moon in Japanese, so they went with it. I don't like the name Elio, and I hate Selene because it's too similar to Serena. Plus Elio was used a total of one time, and only when Sun was already in use and they needed an extra name. So I stuck with Sun and Moon.
As for Kai and Lana, I would fine with them. I just don't use them because GF hasn't. They used Sun and Moon in every piece of media featuring the protagonists and are doing so even now. If GF is sticking with Sun and Moon and ignoring Kai and Lana, I have no reason to go against that.
