Han-Gyaku-Sei Million Arthur

In a Britain besieged by a mysterious enemy, chaos reigns as the once peaceful land faces an unprecedented threat. The only hope for salvation lies in the hands of Arthur, a guardian chosen by the legendary sword Excalibur. However, the mantle of Arthur is not held by a single hero; instead, countless challengers have risen to claim the title, each selected by Excalibur itself. These millions of Arthurs unite to defend their realm, engaged in a relentless battle against the forces of death.

Yet not all are aligned with the mission of these Arthurs. A different faction emerges, known as the AGENT Arthurs, who harbor a dangerous objective: the destruction of Excalibur itself. Armed with the very sword they seek to obliterate, these warriors walk a fine line between ally and adversary. Their struggle unfolds in a gripping tale of rebellion, as they strive to thwart the impending apocalypse while grappling with the complexities of their identities as Arthurs, yet distinctly not Arthurs.
