The battle against demons has raged for centuries, but the tide is about to turn. After Muzan Kibutsuji ruthlessly disbands the Lower Moons, only one survives-Enmu, empowered and more sadistic than ever. As the Mugen Train speeds toward destiny, Kyojuro Rengoku, the Flame Hashira, takes command of a mission that will change the Demon Slayer Corps forever.
Tanjiro, Nezuko, Inosuke, and Zenitsu join Rengoku to protect a cargo of immense importance-newly developed Demon Slayer uniforms infused with wisteria poison. But as the train hurtles through the night, demons emerge from the darkness to destroy everything in their path.
A relentless battle ensues, leading to a clash with **Akaza, Upper Moon Three**-a monster of unfathomable strength. As fists and blades collide, philosophies are tested, wills are shattered, and the line between life and death blurs. Rengoku refuses to falter, but Akaza is determined to break him.
With breathtaking battles, emotional intensity, and a renewed hope for humanity, **"Demon Slayer: The Dawn of Reckoning"** reimagines the Mugen Train arc in a way you've never seen before. The sun is rising, and with it, the end of the demons' reign draws near.
Will the Flame Hashira survive? Will the Demon Slayer Corps usher in a new era? Or will the darkness consume them all?
The train has left the station. All aboard.**
In this story, Tanjiro wasn't able to become a human after the fight against muzan and becomes the new king of demons. Now in the modern era, tanjiro is attempting to create a serum using his blood to make his demons walk under the sun. But he discovers the new hashiras of the now demon slayer are the same hashiras he met in the past.
And that is when he gets worried, because he remembers their strength. But using whats left of his humanity to create a drug that will weaken him so much giving the slayers a chance to kill him. But most of his humanity is now gone.
The now modern hashiras remember their past lives and nezuko, Zenitsu, and inoskue remember their past lives.
