There is one ray of hope, however: an ancient tome known as the Book of Shadows. Class president Ayumi Shinozaki attempted to make use of its magic to resurrect her deceased friends once before, but only compounded the tragedy in the process. And now the book has been lost.
Or has it? When a spiritual photograph turns up, suggesting the Book of Shadows may now reside in the tattered remains of Heavenly Host, Ayumi becomes obsessed with finding it so she can make one last attempt to set things right.
What follows is nothing short of a nightmare.
Picking up two months after Corpse Party: Book of Shadows, Corpse Party: Blood Drive serves as the definitive conclusion to the Heavenly Host story arc.
