After a car accident, Su Hao transmigrated to the Taisho era with memories of the entire Demon Slayer manga and two Mangekyo Sharingan.
When he opened his eyes, he saw familiar mountains. Walking toward him were Kanae Kocho, who should have died at Doma's hands, and a still-young Shinobu Kocho.
He had arrived more than a decade early, before the tragedy began, while there was still time to undo every heartbreaking loss.
Starting with saving the Flower Hashira, Su Hao took one step at a time into this man-eating world.
He had seen the Flame Hashira's burning silhouette, heard the Insect Hashira's restrained hatred, and knew how the prodigious Mist Hashira's story would end.
This time, he had come with memories of the entire story.
Take up the sword, slay demons, change fate.
Let the Flame Hashira's fire never go out, and the flowers of the Butterfly Mansion bloom forever.
