Corpse Party: Book of Shadows is divided into eight chapters, each of which tells its own self-contained short story. Some of them help fill in the blanks of what happened during crucial off-camera scenes from the original game. Others go into the back-story of various characters, helping to flesh them out and make their roles in the series mythos a bit clearer. Still others ask "what if?," presenting an alternate version of events from the first game in which characters who previously died are kept alive and given a fleeting chance to stay that way. And the game's wonderfully-titled final chapter, "Blood Drive," serves as a true sequel, focusing on two of the first game's survivors as they venture somewhere even deadlier than Heavenly Host Elementary School in order to dig up some answers.
