Book of Shadows is a sequel to Corpse Party and features a series of nonlinear chapters. Upon release, the game received mixed reviews from critics who generally considered it inferior to the original.

This 2011 sequel to Blood Covered, Book of Shadows features a series of nonlinear chapters that add new twists and backgrounds for various characters and details important to the storyline. The game mostly takes place during the same time the first game did, continuing from one of the "wrong ends" in Corpse Party, where Sachiko sends the Kisaragi Academy students back in time. For this purpose, she erases their memories except for Satoshi's. He fails to dissuade his classmates from performing the charm, but he joins them, not wanting to let them go alone, sending them on alternative course of actions and encountering several supporting victims in Heavenly Host.

The game's epilogue, Blood Drive, serves as the set up to the eponymous sequel. Two weeks after escaping Heavenly Host, Ayumi and Naomi go to investigate the Shinozaki estate, Sachiko's birthplace, believing there is hope in reviving their dead friends since Naho and Kou Kibiki's existences were not erased like the other victims. At the estate, Ayumi discovers that she is of the same lineage as Sachiko. Hearing an eerie voice, Ayumi uncovers a magical tome known as the "Book of Shadows". Ayumi and Naomi perform a resurrection spell for Mayu, but fail. As compensation for using black magic, the book unleashes its rage upon Ayumi until her older sister Hinoe Shinozaki rushes in and saves Ayumi, at the cost of her own life.

Conversely, IGN's Scott Butterworth was more mixed, rating the game a 5.8/10. He criticized the pacing, length and some aspects of the story, and considered it a niche game for a very small audience.^[7]
