Jishu, an immortal god from high-dimensional space.
Her daily life is to travel between time and space to maintain the balanced operation of countless worlds.
This time, she is about to go to the world of Demon Slayer: Kimetsu no Yaiba.
She has read through the "original books" of this world and knows where everything is headed: the war between the Demon Slayer Corps and Demon Maitsuji Muzan is destined to fail miserably, with the entire army destroyed, hundreds of ghosts running rampant, and the world being disordered.
The purpose of her trip is to reverse the situation and rewrite the ending.
Her plan is: to instigate rebellion to the third string, the second string, and the first string.
However, the moment she fell from the sky and fell into the Palace of Eternal Bliss——
The gears of fate had begun to turn in a direction she could not predict.
Pervert without emotion
The foul-mouthed and soft-hearted Mr. Fengzhu
Tomioka Giyu, a man of few words
And the man who hides in the dark and controls everything - Muzan Kibutsuji
When gods enter the world of ghosts, is it salvation or another kind of perdition?
Purpose: Real strength is not immortality, but choosing to fight even though you know the outcome is bleak.
