With the world at peace, Rimuru Tempest grows bored. Guided by Ciel, his hidden Manas, he creates a parallel reality and travels 2,000 years into the past, leaving a copy of himself in the present. In this ancient era, Rimuru rises as a legendary Ancient Demon Lord, shaping civilizations and magic Disclaimer: This is a fanfiction story created by the author for entertainment purposes only. All characters, settings, and story elements belong to Fuse, the original creator of That Time I Got Reincarnated as a Slime (Tensura). This work is not official canon and is purely a creative exploration of the world and characters in an alternate universe scenario.

A blind girl cursed by her mismatched eyes meets a transfer student with the same golden gaze-unaware he's the leader of one of Japan's deadliest gangs.

Cover is a commission by cbotakuarts Far long ago, the creator Veldanava thought of getting rid of his Omniscience and Omnipotence in order to exist as a part of creation and not something beyond it. Just before doing it, he looked one last time in the future of his creation, to be sure that nothing that could become a threat impossible to dealing with will spawn. But he overlooked something. Countless years later, an odd demoness began to wreak havoc in the Underworld, an abnormal existence on par with the Primordials, who seek greater strength for a secret purpose. Almost 2 century after her, a little blue blob appears in a sealed cave, ecstatic of being reborn in this world at last. A slime, which possess only one half of a soul. Authors note: annex book of the fic here: https://www.wattpad.com/story/384887823-accursed-banished-regretfuls-annex-book This story will take place with a new Rimuru, meaning he's not Satoru, and a former French (yeah, why not). The demoness is an OC linked to this Rimuru as family. Small warning: Mature tag is for harsh thematics that will appear later in the story, like depression and its derivatives, or occasional depiction of violence, mostly mental. The tag isn't for lemons as they aren't put in this fic but will be gathered in the annex book alongside bonus chapters. Still, dirty jokes will occur occasionally. This story will still have some relationships (including polyamorous) and fluffy moments. Reminders: I do not own the rights to Tensura, or any other licences' ideas that will appear in a way or another.

Shadow Slave crossover now included (will resume after current Short Story concludes) Collection of Short Stories. The majority are set in Post-Canon Tensura WN (though I incorporate some LN components when appropriate)

In the taisho era, a young girl named Rimuru, lost everything in the hands of a powerful demon, fortunately she was taken in and adopted by a kindhearted family of charcoal makers. One day, while helping her adopted brother Tanjiro sell charcoal, they found their family was killed except for a lone survivor, Nezuko. Follow their journey as they find and kill Muzan Kibutsuji who is the source of the demons tha plague the world at night Note: This rimuru is born in the demon slayer universe, but i would add fun references and such from that time I got reincarnated as a slime. (I don't own demon slayer, that time I got reincarnated as a slime, or the pictures and videos that may be used those belong to their respective owners and i found them on Google or screenshoted them)

Since no one's done it, I'll do it myself. This book is an experimental reaction fic to my fanfic, Melting the Eternal Frost. The cast is the one from canon, of course, taken mid-Tenma War to react to this cinematic experience. As usual, credit to Fuse for creating the original series.

During Rimuru's evolution to demon Lord, something unexpected happened Rimuru's consciousness travel from one universe to another, possessing the body of an alternate counterpart. but something about this counterpart is different this Counter part was not a Living Person but Instead a Machine Created to Defeated and Kill those beings known as Spirit. What would Rimuru Do in this Alternate world? And How will This Story Goes...well Only Time can tell.

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

In this story, rimuru has died but due to his wishes he went back in time and become a slime? now with his new found powers and skills, he strod off into the unknown and it seems he is not a normal slime but a demon slime? and he is the only SENTIENT BEING IN THIS REALM! Now surrounded by mindless demons, what will this slime do? Rimuru due to his strong if not stronger soul changes his gender into a male Instead of veldora, veldanava will be his 'sworn friend' since there are almost no other sentient beings other than a few Rimuru will also later evolve into a primordial instead of being one from the beginning. don't ask me how I don't know either Rimuru and ciel will also be with each other wayyy longer hence they become a bit 'EXTREMELY YANDERE ON EACH OTHER' uhmm a bit obsessive. also my first time writing a story + haven't read the light novel but kinda know the order and story to an extend + I'm a 6th grader so I don't know a lot of words I can use for my story to express my story BUT I hate spelling mistakes and will probably not make any but a few. I do not own the tensura series or light novel it belongs to fuze san(I think that's his name?) also if any one copies my story without my permission I WILL SEND YOU TO JESUS Taking inspiration is very much allowed

After achieving peace Rimuru was stuck doing paperwork for the last few centuries and was stuck with boredom. Ciel seeing her master's state suggests going back in time to the era when Veldanava created the cardinal world. I don't own Tensura. I adjusted the story to my liking. English is not my main language so don't bother about grammar mistakes too much If you guys want to read advanced chapters go to my Patreon account. patreon.com/Nauty_Manu
