#04 of 2D Game Bunko/Pocketnovels, this is a reissue of 2D Game Novels #31 with alternative cover, but I'm not sure if contents are the same.

There are 2 books yielded from the game "Akatsuki no Goei" made by now discontinued "Syangrila" (once restructured into "AKABEiSOFT2" then split into "hibiki works" and "akatsuki works"), not including reissues. The game itself has 2 expansions.

for the cg sets:
Main part,
1st expansion: プリンシパルたちの休日
2nd expansion: 罪深き終末論
there should be a "Trinity" edition which contains all the expansions but I haven't seen it in the gallery yet.

no info on mugi database yet.

What a pity itself, I was pretty sure the game can be made into anime if Syangrila does not broke up. The storyline of the game is very good, plus bloody D:
