I Cosplayed Demon King Tanjiro, Then Transmigrated into the Original Story

The prequel in this series starts updating on May 10. If you're interested, little darlings, feel free to check it out. Thank you, everyone.

I'm currently doing a major revision of the story to fix plot holes.

The main story is complete. Extras will be posted at unspecified times. Thank you so much for your support.

Please note the pairing warning. I got carried away by a sudden flash of inspiration and wrote a pairing that upset some readers. I'm sorry I didn't give a warning beforehand. From now on, I won't write any pairings other than the ones I've warned you about.

Blurb:

I, dressed in cosplay, transmigrated as Demon King Tanjiro, waking up in the original story.

Giyu's Nichirin Blade was still stuck in my neck.

The will of the world told me: [Keep your identity hidden and lie low for thirty years, and you can go home.]

Home? I thought of the pale face of Lady Rengoku in my memories, the Flower Hashira's life slowly fading away, and the massacre of the Kamado family that had yet to happen.

Then I remembered Giyu, my good roommate back in the real world, waiting for me to come home, feed the cat, and split the rent.

I smiled.

"Sorry, but I'm definitely getting involved."

And so...

A "traveling doctor" who could cure any illness appeared at Lady Rengoku's bedside.

I saved the dying Flower Hashira with medicine I'd given her in advance.

The Tokito family took in a kind traveling doctor, who gave them medicine to bring down a fever.

They guessed at my identity and thanked me for helping them.

But who knew that Master Ubuyashiki's overactive imagination would make the will of the world think I'd become "Yoriichi Tsugikuni," and trigger the Yoriichi blessing...

The Demon King and Upper One are closing in on me. What do I do?!?!

The story is ensemble-focused and will involve many characters. It will include interactions between modern Demon Slayer characters with some original settings and characters from the original story.

The protagonist will try to redeem the demons, but as demons, they will still receive the punishment they deserve.

The author has an enormous imagination and a habit of tormenting everyone.

I like describing the family, romantic, and platonic relationships of the other characters in the story.

My personal ship is Demon King Tanjiro and his good roommate Giyu. The pairings I enjoy are Tanjiro/Giyu (two pairings), Sanemi/Genya, Obanai/Mitsuri, Akaza/Koyuki, and Kyojuro/Sabito. There may be more pairings later.
