You’re the child of Muzan Kibutsuji

He needs not introduce himself, for ordinary folk will never get to know him.
Nor will he need to immerse himself in the sea of humanity, for he has long forsaken any worthless emotion.
Several times now he has risen and fallen, and now he lives only for himself.
"Wanderer" is how he believes he might be best described — he has no home, no kin, and no destination.
Like the breeze, he lives in this world, and he walks its length and breadth.
