Summary
In a dystopian Japan subjugated by the ruthless rule of demons under the emperor Kibutsuji Muzan, the Mazoku Era has transformed the archipelago into a nightmare of iron and blood. Cities, choked by toxic fumes and oppressive laws, are divided between the opulent districts of demonic elites and the squalid slums where humans toil to survive. In a world where hope seems extinguished, a flicker of resistance endures, carried by broken but determined souls.
Muichirō and Yuichirō Tokitō, twin brothers scarred by tragedy, struggle to survive in the underbelly of Kuragari-shita. Their lives, defined by grueling labor, hunger, and fear, are upended when they come into possession of a dangerous secret—a legacy from a mysterious warrior that could alter humanity’s fate.
Amid the intrigues at the pinnacle of Edo’s Tower, the gratuitous massacres and abuse of demons, this story probes the resilience of the human spirit in a world where survival demands sacrifice. Muichirō and Yuichirō must choose between submission or reigniting the flame of a free future.
