This information is from Unco and translated from AIR-千年之夏.

From: "Colourful Pure Girl" in the March edition.

"The author declared that those two kids were not the reincarnation of any of the characters and he doesn't want people think of air like that."

The author also says that those two kids were more of outsider view point. It's like themselves (KEY) are watching the story.

Also, those two children said something at the end, but from the information provided on the site, it says the sentence was not fully represented. There should have some word to make the sentence "right." The sentence before they change was "cruel days are waiting upon them, new days are welcoming us." After putting words into the sentence to make it "right" it reads as "memories of stars gave them cruel days, and give us new memory to start."
