Extensive Collection of Game Material
For anyone who likes the art style of the game, this book is great simply due to the wealth of content. It features character bios for all of the major characers, though in Japanese. But the bios also have full body illustrations of the characters in addition to models of all the facial expressions, sprites, and views seen in game and concept sketches for each character; great concept pieces for cosplayers. It also has pictures of the sprites of each demon along with information about each, again in Japanese, though. The book also has some excellent pictures of the the background art and locations featured in the game. There are also some storyboard sketches and interviews with the game creators.
Though players of the game know it took a minimalist approach to cutscenes and other such flare, the included material is a nice high resolution version of everything in the game.
