In a nutshell: the story of Demon King Tanjiro from an alternate timeline transmigrating into the original story
I once embarked on a long journey. Thousands of years of memories wore me down until, over the course of four hundred years, I had blended the bloody shadows of humans and demons into a gentle twilight.
Then, once again, the unexpected happened.
This time, what vanished was every memory and every trace of my existence. When I woke, I had become Kamado Tanjiro, a charcoal seller struggling through the snow with his family on his back.
I began writing a new “observation log.”
Entry One: The demons of this world are misshapen and ravenous, frenzied shadows condemned to an eternal night with no hope of salvation.
Entry Two: The power system known as “Breathing Styles” is brilliant and tragic.
Entry Three: The most important subject of observation is “Kibutsuji Muzan,” who considers himself a perfect being.
Entry Four: The first swordsman to use a Breathing Style...
Entry Five: The same face, a different presence
Entry Six: ...
And I am the one holding these incomplete notes.
I know who I am, and I don’t know who I am. Demons should not suffer like this; humans should not struggle like this. I have forgotten the answer, but the question itself, along with the power to seek the answer, has long been rooted in the deepest part of this body.
An amnesiac observer puts pen to paper in the wrong era.
He records the demons’ trembling, humanity’s courage, and the world’s cracks.
When the notebook reaches its final chapter, the “solar eclipse” will end, and reality will return
The theme is super new!
