About meeting with Santa Mikado, check out chapter 1 (that's right, the very first one) and 178. On a side note, it is amazing to see that Hata-sensei had the End of the World arc in mind from the very beginning, if you look carefully at the cover page of the first chapter.
I wish that someday Hata-sensei will create a serious spin off based only on End of the World/King's Jewel arc. I would shower him with my monies.
