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). *I DO NOT own Demon Slayer or That Time I Got Reincarnated as a Slime. The characters and plot that are depicted in this story either belong to Koyoharu Gotouge, or Fuse. All art in this story also belongs to its respective owners and I do not own them in the slightest.

Aya, now named Freya, is past friend of Satoru Mikami, one year later she dies at a shooting while drinking at her favourite coffee shop. Now you may be wondering, why would she peacefully be drinking her coffee? Easy! She's deaf... meaning she died because the guy didn't know Sign language causing her to die. She made two v-shaped hands and tapped them twice and made a W with her right hand. [fuck the world!] because they're is no 'the' in sign language she didn't sign one out. Even so know In her next life still deaf she uses her thought process to get by in the world... Wait a second! How is she further in the past, Shizue's a child which just got summoned by Leon and Milim's been bothering her about a fight! Well then... let's take a trip down memory lane. I made this fanfiction for entertainment purposes, I gain nothing by making any of my fanfictions, please enjoy reading this. I also technically didn't finish this, don't expect stuff the last title represents exactly what I ment it to, my laziness!

Rimuru Tempest start having dreams about Shizue Izawa it's been bothering him everyday he always think about her being alive but even if he can bring her back to life he thinks that his broking the promise he made with her but Ciel suggested that how about he turn back the clock so that he can save her before she gave her last wish and correct every mistake he makes in the past This is just a fanfiction I made because I really love that time I got reincarnated as a slime and there's only few fanfiction about it in wattpad so I decided to make my own fanfic I hope you all like it

Veldanava, even as a God, was hard pressed to control the energy of 'nothingness': the origin of all his creations, [TURN NULL]. The actual reason was his finite stomach. So to solve this one, he decided to create an entity suitable to control his powers for him. This leads to the birth of the first 'True Ancestor', the first "True Demon." Later to be known as the Mother Progenitor.

Rimuru achieved everything which was possible but there is one regret he has in his mind even after the 12 years of the great war that he cant save his 'Destined One' So after 12 year he Decided to clear this regret but he don't want to change the whole timeline by directly interfering so he decided to live the whole life again after being reincarnated but this time he has every skill from the moment he reincarnated. Note: I changed rimuru personality a little bit after ch4 , I made him act like evil sometimes. The story also started to change after ch4, You would only be spoiled the events and character names of ln. Thanks @VytsuDesigns for the cover.

This story is about Rimuru going to another world to explore. This is a fanfic. Rimuru was bored of doing nothing so he wants to explore and have some fun. He wants to meet new people and make some new friends with Ciel by his side. ( Note : This is my second fanfic so please support and share your thoughts and suggestions. ) I hope you all will enjoy and like it.

Welcome to the World of Re:Zero x Rimuru! Thank you for joining! I hope you enjoy the story. To all the amazing people helping me improve, I truly appreciate it. I'm not a professional writer, but I love storytelling. There may be mistakes, so feel free to point them out so I can fix them. I tried my best to make the story understandable, but you the readers are the true judges. Of course this story contains spoilers! It has been 1M+ years, and the world has changed-just like our beloved slime. Rimuru has evolved into a being whose rage alone could erase existence itself. Tired of ruling, he decides to resign as king and explore worlds beyond Veldanava's creation. In his journey, he discovers a land filled with humans, elves, demons, and beings known as "whites." Admiring the elves, he chooses to stay there for a while. Upon entering this world, he encounters a beautiful half-elf and her companion, Puck. Will Rimuru be able to win over the elves and the girls he meets? Let's find out! DISCLAIMER! This Rimuru has a different personality-he's more playful and childish, similar to Veldora and Milim. This story also contains strong language and mature themes. (I don't own any characters or images used in this story.)

After living for billions of years and reaching the end of everything, Rimuru Tempest realizes one painfully stupid truth: he may have won at life, but he completely fumbled love. He treated everyone precious to him like family, ignored every confession, dodged every chance at romance, and only understood what he was missing when the universe had already gone silent. Watching him drift alone in the void for over three billion years, Ciel finally snaps. With one forbidden decision, she rewinds time itself and sends them back to the distant past, before Rimuru was ever Rimuru. Now reborn as human Satoru Mikami, armed with all of his future god-tier powers but none of his memories, he's thrown into a world that has no idea a final-form god has just arrived way too early. With Ciel now at his side, canon is doomed, fate is panicking, and Satoru's second chance at life is about to become a chaotic mix of mystery, overpowered nonsense, emotional reveals, and harem-level romantic trouble. Because this time, Ciel only has one goal: Make sure her master stops being dense before history embarrasses him again.

Need some sweet dose?
