[Demon Slayer] The Curly-Haired White Moonlight Who Became Tragic Girl

Here's a recommendation for my other ongoing story: [Crossover] Gintoki Sakata, Substitute God

Blurb:

Gintoki Sakata has a secret. By day, he lives in Kabukicho. At night, he finds himself in a place called Tokyo.

After spending a few carefree months there, he gets beaten up by a white-haired guy and discovers that the place is full of creatures beyond human understanding, like cursed spirits and yokai!

Even worse, he can't get back home! To survive, he takes up the mantle of the God of Calamity, inherits a shrine, and opens an online odd-jobs agency that takes requests for weddings and funerals, exorcisms, curses, fortune-telling, and cleaning. He gathers the power of faith and becomes a famous psychic master.

That white-haired guy who's always right by his side stands with Gintoki during a psychic showdown program, tending to his every need like an assistant. When it gets broadcast live, it shocks the jujutsu world!

Shoko: "Is this really the same Gojo I know, the totally awesome and arrogant one?"

Brain: "The strongest in jujutsu? Hah."

Yaga Masamichi: "Don't go around scamming people with that charlatan. And don't tell them you're a teacher at Tokyo Jujutsu High!"

Junpei: "As expected of the MADAO cult leader! Even Gojo-sensei is one of them!"

Gojo Satoru: "Open your phone and vote for me, thanks!"

*********************Main Story Blurb***********************

After taking a job, Gintoki Sakata accidentally transmigrates to the world of Demon Slayer, where he meets Muzan when he is still human.

Muzan: "Hey, you messy-haired guy over there. Pass me the medicine."

Gintoki: "Who's a messy-haired guy, brat?! Your seaweed head has no right to call me that!"

Much later, Muzan stands in the rain before the long-cold body of the silver-haired man with curly hair. A trail of water silently slips down his face.

A thousand years later, Muzan looks at the silver-haired man with curly hair before him, exactly as he was before, and falls silent.

Some silver-haired guy with curly hair: "...And you are?"

The early story takes place in Heian-kyo, with Muzan as the main character. Later, it will return to the Taisho era. I can't promise what happens to everyone else, but I'm definitely saving Kyojuro!!!

The plot has been heavily changed, and there are piles of original additions! I'm a devoted happy-ending fan, so there won't be any angst. The CP is the scumbag boss.

Theme: Tormenting the scumbag boss and getting a happy ending
