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!

 
Advent is a group of criminals that escaped from The Cell.
It consists of Shiori Novella, Nerissa Ravencroft, Koseki Bijou, Fuwawa Abyssgard,
and Mococo Abyssgard, who were all imprisoned for various reasons.
However, they escaped from The Cell to achieve one shared goal: to rebel against the world, their destinies, and their monotonous lives.

 
Justice has been given but one mission:
to bring justice to the world.
They are a group of rowdy troublemakers who work on the fringes of an uptight, strict organization.
Elizabeth Rose Bloodflame is Justice’s manager, but she does not necessarily hold more power than the other three:
Gigi Murin, Cecilia Immergreen, and Raora Panthera.
They are currently on a mission related to a recent prison break from “The Cell”
and seem to have loose connections with the escapees.
