Kaguya Houraisan - a lunar refugee
Princess Luna - the rise and fall of the moon
No one would think that these two's lives were entangled with each other. But, with so many similarities within one event, can one really just subject them as coincidence? Follow through what happens when Kaguya receives a formal apology in regards to a certain eternal moon.
These two sacred countries... both of magic and harmony, even though from different methods, are eerily similar... would it not be common sense that these two are somehow intertwined, even from the lands where common sense has turned on its head? Watch as the Lunatics of both worlds meet and greet one another, and the border of harmony and chaos blurs even further than before.

An idea I had on my head for quite a while - so long that my brain clogged any idea pertaining to something other than this. This will be considered a one-shot, though connections may appear in any future ideas I may have. SAD tag because I tried to incorporate a sad overtone, but I'm not sure how well it went over. Also, Teen rating for one reference to incest and one or two expletives.
--EDIT--
BAM, I've decided to continue this into a... not... one-shot... thing. Whatever. Read on as my wonderful little headcanon is splayed out before you.
