Demon Slayer: After I Entered the Demon King’s Body

[Two male leads, top-focused. Unless something unexpected happens, the pairing is Wucan.]

One day, Huang Yuan Wucan found himself inside the body of the main villain from the Demon Slayer manga he'd read.

As an overworked office drone, Huang Yuan was numb with despair. He hadn't even spent all the money he'd saved.

So you really do get transported just because you have the same name?!

Whatever. First, he'd use the Demon King’s body to stay alive.

As a demon, was he supposed to live in darkness, never seeing the sun? Then he'd force humanity to accept demons!

As a demon, did he have to drink blood? Then he'd make the blood trade legal!

As a demon, could he not touch sunlight? Then he'd build a city of eternal night!

Run into characters from the original story? Put them to work!

The Twelve Kizuki? No illiterates! No one who can't do the books!

The Demon Slayer Corps? Sign a contract and work as bodyguards!

One day, the original Demon King's soul inside his body woke up...

Huang Yuan Wucan: Ah, that cowardly, stupid demon's awake.

Muzan Kibutsuji: Get out of my body!

Huang Yuan Wucan: Useless, disobedient, and always causing trouble. I guess I'll have to train him properly. *grins*
