Hn... Blue Sky Kingdom does sound like something coming out of a fantasy manga. I don't think I've heard of Pikarigaoka Prefecture, but neither have people so far known about Saitama Prefecture.

[Konata walks close to her, towered by a whole millimeter, which would make Hime taller everywhere on Earth but the United States.]

I don't think I've seen you around! I'm Konata Izumi, a student from Saitama Prefecture! Nice to meetcha!
