However, five girls who are members of the Occult Research Club have not gone home. Calling it ‘the first cool of the evening quest’, the girls have decided to investigate a rumor about the Tokugawa buried treasure and sneak into the university’s data warehouse. What they find is not the rumored treasure, but rather, two extremely well-preserved mummies of two young girls.

Sayaka Kamoshida, who is the one to originally get her friends to sneak with her into the warehouse, secretly steals the mysterious ‘stone of life’ that was placed inside both of these mummies. Disappointed in the outcome of not being able to find the hidden treasure, they leave the data warehouse. The theft of the ‘stones of life’ is actually the trigger to resurrect these two mummies.

One of the resurrected girls was the daughter of a former Baron, who, due to an unexpected incident, became an undead being via magic. Her name is Euphrosyne Studion. The other is Euphrosyne’s maid Alma V, who was created from a homunculus. Now, the two girls attack the members of the Occult Research Club in order to get the stolen stones back.

Can the members of the Occult Research Club survive this development? Also, why were the stones of life stolen? A bloody tragedy of the late-night student dormitory attacks…
