As the Nation faces invasion from the peoples it has pillaged for a century, one man defends it: Derek Rondo, the second coming of the Mercenary King Vult. He fights for his country, but plots to seize the throne for himself... A new visual novel betrayal epic begins from within!

To the west of the continent of Serenus lies the land known only as the Nation.

Founded over a hundred years ago, this country represents the apex of both corruption and prosperity. Its decadent empress Ladomira turns her nation's vices—as well as her own otherworldly charm—to her advantage to maintain her power as her armies pillage and plunder in the neighboring nations, leaving the seeds of tragedy everywhere in their wake.

In the face of this peril the neighboring states, having finally united in a Holy Alliance against their oppressors, launch an all-out assault that quickly threatens to overpower the Nation, surrounding its strongholds from all sides.

But before peace and justice can be returned to the land, a single man stands in their way. Derek Rondo, commander of the Nation’s army and hailed as be the second coming of its founder Mercenary King Vult, successfully repels the allied armies under the orders of Empress Ladomira. However, he holds another desire in his heart... the desire to usurp the throne.

Derek burns with ambition to take down not only the invading knights but Ladomira herself, and claim everything for his own!
