In the lightless depths of the world lies The Cell, where dangerous untouchables are imprisoned. Among those prisoners are Shiori, Bijou, Nerissa, Fuwawa, and Mococo, the five who would later call themselves Advent. Though their prison life was uncharacteristically comfortable, they wanted more—they wanted freedom. Meanwhile, Elizabeth, Gigi, Cecilia, and Raora, the four defenders known as Justice, find themselves embroiled in a bitter battle with boredom. The two groups soon find themselves facing off in an ancient contest, the Oliventis, with the prisoners’ freedom on the line. A battle for the ages is about to begin!
