Taking place in the Erebonian Empire alongside Zero no Kiseki and Ao no Kiseki, this RPG game centers around the inception of "Class VII" - a unique group at Thors Military Academy comprised of both aristocrats and common Erebonian citizens. Unlike the rest of the academy, where segregation between the classes is prevalent, "Class VII" represents a diverse blend of social statuses.
As players embark on this adventure, they join Class VII on their educational journey, complete with specialized field training sessions across Erebonia. Throughout this experience, the class transforms and challenges their preconceived beliefs about social hierarchy. Simultaneously, players discover the truth about the empire and the power struggle between the four noble houses and the reformists aligned with Iron Blood Chancellor of Erebonia - Giliath Osborne. The storyline takes a captivating turn as it threatens to ignite a civil war between the two classes.
