3 years after the defeat of Yuuki...

In this timeline, Rimuru is bored and getting increasingly impatient. In a hope to satisfy this eternal boredom, he ends up, with the help of Ciel-sensei, dimension-hopping into the world of Demon Slayer. 

How will things play out in this new world and how will the story of Demon Slayer change?

(Rimuru is very heavily nerfed, at least for now).

Demon Lord Shinobi by Hadanuke
6 parts Ongoing Mature
This is a story of Rimuru going to a different universe to have fun and basically do the same thing he did in his previous world. Create a world where he and his people can live a good life. How will that work in the shinobi world? Will he able to create peace while being called the Demon Lord? This is a rewrite of my first story [Rimuru goes to the Shinobi world] This story will feature more thought out plot and better done story and hopefully less typos and better update schedule and a lot more though put into the direction of the plot so that It doesn't bite me in the ass like last time. I hope that you enjoy reading :) Also on a different note, the title pic isn't mine, I didn't draw it, AI did. Sorry to disappoint, you can deck me in the shnaz in the comments about it.
Whispers of Affection: The Milim and Rimuru Love Story (Rewriten ) by Friris
26 parts Ongoing Mature
Hello! This is the rewritten version of the story. In this updated version, there will be several changes, including adjustments to the relationship between Rimuru and Milim, and at some point, the story will diverge significantly from the original light novel. Please excuse any errors in my English, as it's not my first language. If you notice any inaccuracies, such as errors regarding the kingship of certain countries, please leave a comment, and I'll make sure to correct them. Thank you for your understanding and feedback! Additionally, I will be evolving Raphael into Ciel quite rapidly, but Rimuru will not be progressing from Demon Lord to True Dragon at the same pace.

10 parts Complete
"I'm gonna be Rimuru-sama's wife for sure!" shion said as she ran off to get a dress. "No I am!" shuna said as she too ran off. "In your pathetic dreams!" Testarossa exclaimed running off. "I'm going to marry rimuru!" milim said as the rest of the women, and even some men, ran off. Rimuru sighs deeply at the sight. He can believe that the bickering progressed this far, no shame really. post war, rimuru was living his life happily and freely after becoming a God. he was enjoying his day when all of a sudden, the girl's started bickering about who would be the one to marry him. not that it mattered to him, he only ever saw them as friends that he treasured the most than a romantic partner. to stop this commotion, benimaru suggested that they should host a ball to see who their master would pick. Rimuru thought this was a waste of time but agreed anyways for the sake that this would all stop. Little did he know of the new adventures he was about to encounter. Inspired by a Taylor swift song and I think yall know what song judging by the title. This story includes: -Lgbtq -harem (but the main ship is Diabru) -smut (maybe idk I haven't written one before but I read some) -jealousy -op characters
