Corpse Party: Blood Drive

Continuing from the prologue included in Book of Shadows, Naomi manages to save Ayumi and takes her to a hospital. The Shinozaki estate and tome subsequently vanish without a trace. Ayumi had been severely ill for her misuse of the "Book of Shadows'" black magic. In the hospital, a woman claiming to be a spiritual associate of Hinoe's visits Ayumi. This woman belongs to the "Wiccan Institute", an organization that worships spirits. She tells her Hinoe's last wish, which is to regain the "Book of Shadows" or the world will fall into the abyss. This is partially a lie, as the woman is under threat of other organizations to get Ayumi to find the book, which they wish to use for their own gain.
After being discharged from the hospital two months later, Ayumi returns to Kisaragi Academy where Satoshi and friends give her a warm welcome. However, the absence of their dead friends is a constant reminder of their inevitable reality. A new teacher's assistant, Kuon Niwa, supervises their homeroom. Later, on her way home, a black hooded boy approaches Ayumi and tells her, "If you reclaim the "Book of Shadows" and use it at Heavenly Host, those who have died there will be revived.". Ayumi pledges that she will once more take back the "Book of Shadows". The trail leads into the previous residence of Makina Shinozaki. To make matters worse, Heavenly Host's curse is expanded by the "new Sachiko", later named "Sachi".
