Guided by the threads of fate, the young women gather once more at the academy. While investigating a series of bizarre murders, Imari and Aki head to a bank to uncover the true nature of the "Spear of Longinus"—an artifact allegedly kept in a safe-deposit box by the archaeologist Soji Furuya. However, they are abducted by robbers sent by an organization also seeking to obtain the spear. In this desperate situation, the "power" of the Spear of Longinus triggers the reawakening of Kitami’s personality—which had been sealed away within Imari—and the spear ends up in her hands... The terror of "Walpurgis Night" returns. The young women assemble in the forbidden basement of the academy. A nightmarish ordeal is brought back to life.
