The story of Heavenly Host High School is not the only urban legend that began in the town of Tenjin... Decades ago, a hidden operating room was found under the local Divine Blessing Hospital. It is said that a rogue doctor committed horrible experiments in this room, but all information about the doctor and his work seemed to disappear before anyone could learn the truth.
Six souls are drawn into a twisted recollection of the mad doctor's project, cut off from the outside world. Soon, they will learn the truth of the old Divine Blessing Hospital and its creator...
The story takes place a couple days after Corpse Party D2: Depths of Despair's best ending.
