What if Rimuru was instead reborn as a primordial demon; the strongest in combat and intelligence. He reincarnated just before Star king dragon Veldanava created the omniverse; it was nothing but a void, his soul being exposed just a little to turn null made his soul undergo a change. Making him an individual with a high evolutionary potential

80 years have passed since Yuuki's defeat. Rimuru, after dwelling for countless years at the end of time and space, has surpassed Veldanava in terms of strength and is, therefore, the strongest being in the Cardinal world. With his strength, he easily dealt with the aftermath of the final battle and accomplished his dream of coexistence between monsters and humans. Although he is happy with the results, his daily routine consists of constant paperwork. During one of these boring days Ciel, who is worried about the mental state of her master, suggests creating an alternate Timeline and traveling back in time. Rimuru, not wanting to do everything over again, comes back with an alternative idea. Going back in time but with one addition: instead of traveling to his original time of reincarnation as a slime, he decides to go much further in time and become one of the ancient demon lords.

After the meeting with Shizu and gaining a human form, Rimuru decides to follow the three idiots back to Blumund where he takes the Adventurer Guild test and learns how to summon demons. Back at his budding village, he give this demon summoning thing a try, and somehow gains a white haired secretary. Not long after, while celebrating his new taste buds, Rimuru's subordinates tell him of a tragedy they found and hand him its only survivor: A very greedy little girl. All characters are owned by Fuse and who ever currently has the Tensura IP. This one is a wild idea I got while reading "Dominant Run" by @Greyninja27 (You should go check it too!) And you can definitely see the similarities and inspiration.

Rimuru chooses to return to the past even if he has to erase what he already has to make a better Tempest kingdom than before. Just so he can have even more friends and loved ones then before that he lost, or was not knowledge enough at the time to help grow and become better along with himself and his nation. He also does it so he can make it so paperwork is someone else's problem but he will never say that. Little does he know that doing that gives him an even worse daily activity to deal with... Rimuruism

The world before Rimuru's reincarnation reacts to their future! Currently, only the demon lords would foresee the future events, but soon, more characters would join! This, however, contains slight spoilers for the anime-only, as I will add LN content! But I will put some warnings in the title if they are LN content! :D I hope you enjoy!

After Rimuru defeated the evil dragon Luvelgé formally know as Ivaragé, the world Veldanava created was destroyed. Rimuru found the truth about himself...

Sleeping in the voids embrace, he awakens once again, yet this time serving someone as a butler

Have you ever wondered what things would be like if Rimuru actually stuck to what he had said when he died? "In my next life, I'm gonna go on the prowl! I'll hunt down all the ladies!" Well, let's find out together as Rimuru starts his next life in his new world. A slime, yes, but a slime on the prowl. Just a fun little story I thought up while thinking of what next to write with my current tensura story. That said, this book has nothing whatsoever to do with that ever-lasting book pretending to be a small novel. No, this is its own thing so have fun reading!

Future Rimuru rewinds time to his Demon Lord evolution to fix everything, but instead gains a desire-manipulating skill that causes lust-driven chaos and forces him to wear a blindfold to control it.
