Demon Slayer: The Box of Lingering Embers

Warning: This story contains original characters and settings that may cause some differences from the source material.

She is a Gray-Scorched Demon who survived the Muromachi period. With one finger, she can burn an Upper Moon to actual ash.

She is a shrine maiden who was forcibly turned into a demon during the Sengoku period. With moonlight in her hands, she can even briefly reverse demonization.

After centuries of fighting, cold wars, making up, and fighting again, by their seventeenth reconciliation, all they wanted was to enjoy a quiet romance.

But then they passed through the Taisho era,

The Hand Demon was instantly reduced to ash,

Kyogai was so scared he set himself on fire,

Rui lasted less than three seconds,

Akaza was sent running with a single move,

Daki begged to die,

Hantengu didn’t even have time to release his clones,

and the Infinity Castle was locked away in the Gray Realm…

They never joined the Demon Slayer Corps, and they never helped Muzan.

They just took care of every tragic death in the original story because they couldn’t stand the sight of them.

Tanjiro, Nezuko, all the Hashira, Zenitsu, Inosuke, and everyone else… they all lived to see peaceful times.

Yet nobody knew these two women were responsible.

“Try running away again, and see what happens.”

“I’ll burn down your shrine, and you’re still coming with me.”

Obsessive lovesick girl × stubbornly devoted partner. An overpowered female lead finds love and casually turns the Demon Slayer timeline upside down!

Canon pairings remain rock-solid, no out-of-character behavior, and a mix of satisfying power fantasy, angsty romance, sweetness, heartbreak, and a happy ending for everyone.

A 400,000-character roller coaster of sweet and painful romance. Complete. Hop aboard!
