This is a set of two books: Shin Megami Tensei Devil Summoner: Akuma Zensho (Devil's Compendium) and Devil Summoner: Soul Hackers Akuma Zensho Dai 2 Shu (Devil's Compendium Volume 2). Both have been confirmed to work. Shin Megami Tensei Devil Summoner: Akuma Zensho includes the obi (sleeve), postcard (with age-related stains), and a special iron-on transfer. Both cases have scratches and other damage, and the discs have some scratches and dirt. The instruction manuals for both are in relatively good condition.
