Muzan, I'm Here to Take You In

[A Mischievous Yokai of Unclear Nature + Demon King + Anime Crossover]

A chance encounter that began over a piece of rice cake led to Hayamae taking care of a sickly young master at the Takado estate on behalf of a shrine maiden.

Later, out of pity for an innocent noblewoman, she cleaned herself up and married the sickly young master.

Their genders didn't match, but that was fine.

Their ages didn't match either, but that was fine too.

After all, the people in the great estate had long since lost all patience with the ailing young master. They didn't care who the bride was,

so long as it kept outsiders quiet.

But the eldest young master, whose life had always gone badly, looked at someone who could run freely and bask in the sun every day, and his hatred grew.

He did plenty of terrible things.

Their entanglement lasted a thousand years.
