In a world where coexistence between humans and those with special abilities is fragile, a young orphan named Koji emerges as a central figure. Carrying a faulty pact, Koji faces grotesque creatures known as Gyakus in the city of Dynami, plunging it into ceaseless and deadly chaos.
The once peaceful city becomes a battlefield where millions of lives are lost. Koji, determined to survive and find answers, faces not only the monstrosities that arise due to his pact, but also the guilt and responsibility for the disaster he brought. Amidst the devastation, he finds himself embroiled in an endless war, struggling to discover the meaning of his existence and a way to restore peace. With each challenge, Koji seeks allies and faces powerful enemies as he tries to find purpose and bring balance to a world on the brink of collapse.
