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).

Tensura: Melting the Eternal Frost - Book 1
This story depicts an alternate timeline wherein Velzard attends Walpurgis after sensing Veldora's presence. She subsequently meets our protagonist and becomes interested in him after his display at the meeting. After thinking for a bit, she decides to move to Tempest and becomes a close ally of Rimuru. Rimuru and Velzard will sometimes be out of character since it's unavoidable. Our protagonist will be more rational and have an actual spine, while Velzard will not be as cold and ruthless as her canon counterpart. Besides, Velzard lacks substantial characterization, so I decided to write my own interpretation of her personality based on the original light novel. I recommend at least having seen the second season of the anime, since my story picks up from there. This fanfic will follow the main story beats of the original light novel, so some arcs will be glossed over with minor changes. I'm somewhat OC, so expect a lot of chapter edits or updates, as I tend to reread chapters and catch minor mistakes here and there. (Note that this is Book 1 for the full story.) Also, it goes without saying that I do not own the series 'That Time I Got Reincarnated As A Slime.' Check out and read the original light novel written by Fuse.
Jewel of Tempest
Rimuru was taking a break after the entire orc invasion incident and decided to take a stroll through the forest. While walking along he runs into a monster that was run out of their home by the orcs and lost their entire family to the attack. With nowhere to call home and no family to go back to, Rimuru accepts the monster into the new and growing town as his adopted daughter. The story will follow the main story beats of the light novel, but events will be changed due to a close bond forming between Rimuru and the new monster. The bond will be explored along with the world around the two of them, giving more depth to the characters and allowing them to move outside of the main story's narrative. This is my first time writing something like this so I apologies if there are any glaring issues you may notice. With that said if you see something that could use improving, I invite you to drop a comment and let me know about it so the story can be improved for everyone. The Mature rating is mostly just to cover my bases as I don't know where things will go as the story progresses. I of course don't own "That Time I got Reincarnated as a Slime' so please check out the original work by Fuse.
New Game +
Rimuru Tempest, now at the absolute pinnacle of his power, stands as the revered leader of the Jura-Tempest Federation. He has seen it all: triumph and heartbreak, loyalty and betrayal, the rise of his nation, and the tragic price of war. But what if he could do it all over again? Ciel performs an unprecedented feat-sending Rimuru's consciousness back to the very moment of his reincarnation. This isn't a second chance; it's a New Game +. Armed with the wisdom of a god-tier being, the memories of a fulfilled future, and the power of a True Dragon, Rimuru must navigate the pitfalls he once faced as a naive, newly-reborn slime. This time, he won't be caught off guard by the schemes of Falmuth, Clayman, or the complex political machinations of the world. With his foreknowledge, Rimuru is determined to build a true paradise, a nation where no friend is lost and no sacrifice is in vain. But even with his immense power and knowledge, the past isn't so easily rewritten. New variables and unforeseen challenges await. Can Rimuru truly create a perfect world, or will the weight of his own godhood and the very nature of time itself create a different, darker path? --- Disclaimer This is a work of fanfiction.

TENSURA SPECIAL
In this fanfic, this story will briefly discuss Rimuru's mindset (which passive & pacifistic ). This new version of Rimuru will have proper ruler's attitude and not allows apologizing for the smallest mishaps. But don't worry will still have his personality but there will slight improvements. ( let's be honest he deserves respect) In in my personal opinion, I never did understand why Japanese animes allows that 'no-back bone main character' who even lets his subordinates boss him around a little when his is supposed to be the master!!! smh . However on the contrary, they do have those lovable rage moments, barely. Now to continue my outline of this fanfic, this will not be the regular tensura slime we know and love. The world of tensura will take place a few years after The Great Tenma War.... No there will be no harem involving hinata, velzard, velgrynd or luminious. There maybe a chance with chole , ...maybe! I have some class. Relationships who knows ??? Not me... ::: rimuru x ciel ??? rimuru x chloe ??? rimuru x shuna ??? rimuru x shion ??? This is just brief outline of how I want Rimuru to be in this story. I hope you find it entertaining for my first writing publics work. I will give my thanks the original author who came up with such a master piece of work. I truly enjoy watching the anime and manga.

Rimuru restart : rebirth of the perfect life
Ten years after the end of the Great Tenma War, the world is finally at peace. Rimuru Tempest has become something beyond comprehension-a godlike being with uncountable power, unlistable skills, and a divine weapon forged from Genesis-class blades. And yet, buried beneath his calm smile and mountain of paperwork lies a quiet, aching regret. He couldn't save Shizu. He couldn't reach the Ogres in time. Despite all he's built, those moments still haunt him. But when a single question leads to an impossible answer, Rimuru realizes one thing: With his current power, even time itself is no longer a limit. Now, Rimuru travels back to the past-to rewrite his story, save the people he loves, and create the perfect future he once dreamed of. This is a story of second chances, deep regrets, and a god who still carries the heart of a slime.
