A familiar, thin figure was standing at the doorway.

He wore a yellow and black square haori, and his long, deep red hair was unusually tied in a high ponytail.

He was holding a katana that he had never seen before.

That was the back view of his father, Tanjuro Kamado.

And facing Tanjuro face to face.

It was a man Tanjiro had never seen before, dressed in a black suit and wearing a small top hat.

Because Tanjiro fell in the snow, he couldn't see the expression on his father's face, who was turned away from him.

But he was able to see the other side.

—The man in the black suit, his red eyes revealing a look of horror.

That was an expression as if he had seen a ghost.

A distrustful emergency call led Ling Ke, who had transmigrated to the eve of the Third Great Collapse, to be used as a guinea pig for several years, suffering immense torment. Meanwhile, the Crimson Phoenix had already "transcended to the mortal realm," Kiana was in Anti-Entropy, Mei was in World Serpent, Bronya had long since reunited with Seele… and Ling Ke had become the Herrscher of Domination for thousands. "From this moment on, I will complete my revenge in this world!" The transmigrator from the Celestial Empire, already completely corrupted, revealed a terrifying, sinister grin.
