Summary
Zenitsu Agatsuma has lived her entire life beneath the lanterns of the Entertainment District.
She knows nothing of Demon Slayers.
Nothing of demons.
Nothing of the world beyond the district.
At twenty years old, she has become one of its highest-ranking courtesans, known for her extraordinary beauty, impossibly long golden hair, gentle temperament, and uncanny ability to hear things others cannot.
Then three strangers arrive.
One is a wild-eyed man in a boar mask.
One is a young woman carrying a mysterious wooden box.
And one is a kind young man with hanafuda earrings who becomes very flustered when he learns her surname.
Their arrival introduces Zenitsu to a world she never knew existed.
But something stranger is waiting for her.
She has begun dreaming of a little boy.
A boy she does not know.Series

Summary
Zenitsu Agatsuma has spent twenty years beneath the lanterns of the Entertainment District.
After the battle against Upper Six, she leaves the only home she has ever known and begins traveling with Tanjiro, Nezuko, and Inosuke.
But the farther Zenitsu travels from the district, the more frequently she dreams of a life she cannot remember.
A sickly little boy.
A quiet home.
A mother who loved her son more than anything in the world.
And a voice that keeps calling her Mother.
As fragments of her forgotten life begin returning, Zenitsu discovers a connection to the Demon King that she never could have imagined.
Somewhere in the darkness, Muzan Kibutsuji remembers his mother too.
He remembers loving her.
He remembers losing her.
And most painfully of all, he remembers how he was responsible for her death.
Now his mother has been given another life.
The question is whether a thousand years of hatred and bloodshed have made it too late for a mother and son to find each other again.
Zenitsu must eventually choose what kind of future she wants:
One where she simply remembers the son she lost...
Or one where she tries to reach the person he became.Series

Summary
Zenitsu Agatsuma remembers being a mother.
She remembers a little boy who hated medicine, who feared death, and who believed that becoming strong meant never having to be afraid again.
She remembers loving him.
And now she remembers how she lost him.
Muzan Kibutsuji has lived for a thousand years with the knowledge that he killed the person who loved him most. When his mother returns to the world in another life, he is offered something he has never believed himself worthy of receiving: another chance to stand before her.
But Zenitsu's love cannot undo the suffering he has inflicted. The Demon Slayer Corps still intends to destroy him, and the dead cannot be returned simply because their killer has finally learned to regret his actions.
As the final confrontation approaches, Zenitsu must discover whether her promise to her son can coexist with her responsibility to the living.
Tanjiro, meanwhile, has made his own promise.
He will protect Zenitsu.
Even if doing so means standing between the woman he loves and the monster she remembers as her child.Series
