Silverio's setting is based approximately fifteen hundred years from now, just over a thousand years after a massive disaster obliterated the civilizations that existed then.  The disaster was caused by a dimensional reactor melt down (basically, a reactor that draws energy from higher dimensions) and it basically erased Japan, the entire east coast of China, and most of Alaska (along with most of the islands in the Pacific).  In exchange, it created a 'second sun', known as 'Amaterasu' in the air, merged facilities from all over Japan with buildings and cities already existing on earth, and caused all sorts of effects on physical laws.

The biggest effect - and the one that destroyed civilization as it existed up until then - was the effect of 'Astral' (a type of higher-dimensional particle) of eliminating conductive resistance in metals... meaning that superconductors and devices reliant on being able to alter or control conductivity (computers and circuits) became useless.  This basically ended information technology.  Another effect was that, the closer you got to Amaterasu (ie. higher in the sky) the thicker the air became, to the point where using airplanes was impossible and escaping the planet was hopeless (thus eliminating rapid transfer of goods). 

Another issue is that, without computers, precision manufacturing was no longer possible, and humanity has basically fallen back on what amounts to cottage industry for manufacturing.  If it weren't for the bits of surviving Japanese tech spread over the face of the planet during the disaster, civilization probably would have died permanently.

The country in which the story takes place is named Adler, and it consists of France, Germany, and most of Northwestern Europe.  It is a country run by a combination of military nobles and a military dictator (It is sort of like the Nazi-era Chancellor position in that way).  The country is very much a nationalist state, and its growing technological advantage, primarily represented by the Esperant (enhanced humans who can use Astral to strengthen themselves and create effects on reality) and its extensive use of electricity (the loss of conductivity actually means that energy efficiency is much higher than in the old world, lol). 

The two countries mentioned in the game are a religious state that translates as the Canterbury Theocracy (a nation encompassing the British Isles) and the Mercantile State (a country that seems to be made up of the territory of some Mediterranean states).  Rusheed, one of the major characters, is a diplomat/merchant from the latter, incidentally.

Adler is really, really prosperous, even by our standards... but it also has the downside of a slum that makes the ghettos of Nazi-occupied Poland look pleasant (I think the concept was actually based on the Forbidden Zone from Akatsuki no Goei) and a tendency toward authoritarianism, militarism, and nationalism with leftovers of favoritism for those descended from the Japanese (the biggest world religion is one that worships 'lost Yamato' as a god, lol).

One of the funny things  about this VN is the naked Japanese-favoritism... in particular, descendants of Japanese who were transported to various regions along with the facilities that merged there inevitably have much higher basic abilities than the rest of humanity (they are more intelligent, stronger, faster, etc).  Japan is worshiped or at least referred to as a deity by even those who don't believe, which made me rofl hard at first.

Anyway, having finished this VN a second time, I'm going to rest a few days, work on Dracu-riot a bit more, then get ready for next month's releases, lol.

VN of the Month, March 2016

I doubt anyone seriously thought it could be any other way, but Akeiro Kaikitan wins my VN of the Month, 2016.  While I do intend to get to the remaining releases later, at the moment none of them are high on my list of priorities.
