Magatama Idol Kaguya explains:Edit
"Wow, tonight's sky is amazingly gorgeous. Look, you can see Libra there! But did you know that the star and the constellation are different? See there, on the left, is the star. But if you look from there to the right, all that is the constellation! Of course, I know about it! I'm from the Moon, so have a much closer view, you know!"
