There is a legend on campus of an underground room where debaucherous orgies and magic rituals once took place. The room was supposedly sealed off after a human sacrifice was performed there. As the thirteenth anniversary of this grizzly event draws near, someone is plotting for history to repeat itself. Is it the sweet, beautiful class president, Shiraki? The kinky Saeki, whose obsessed with the occult? The innocent Imari? The well-endowed art professor, Miss Takashiro, or the sexy campus doctor, Miss Kitami?
Minase was a mild-mannered junior who never thought twice about magic or campus legends. But then he found the mysterious “Bible Black,” the book of spells that started it all thirteen years ago. Minase now has the power to control others and get any girl he wants, any way he wants. Will he be tempted by the dark path of debauchery, or will he use his power to stop the upcoming sacrifice?
