Summary
It's been 100 years since the end of the Great Tenma War, and Rimuru was doing his paperwork. To kill his boredom, he decided to visit his old world. But instead of seeing a normal human world, he sees Hunters, Dungeons, Gates, and Monsters. This story will follow Rimuru's journey in this new and old world with the Monarch of Shadows.
I am a new writer, so try to ignore the grammatical mistakes and writing fluency. I also took inspiration and ideas for plot from some other authors. I will give credits to them when I use.
I do not own Solo Levelling and That Time I Got Reincarnated as a Slime. All rights go to their respective owners.

Summary
Rimuru Tempest was just bored out of his mind—he didn’t mean to bulldoze canon like that. It’s not his fault he has ridiculously loyal subordinates. Oh, would you look at that? He just devoured Kocho Kanae before she could die... and restored her body. Oops. He didn’t mean to save the Tokito twins’ family either. That just sort of happened.
He still enjoyed hanging out with the Kamado family—no one can sue him for saving them, right? Or for casually stealing that Muzan guy’s Upper Moons. Honestly, things just kept happening.

Summary
For nearly four centuries, Zaphandor, the last living archmage of a once-great wizard’s guild, defied time itself. From his floating citadel in the heavens, he wielded magic with such mastery that upholding an entire castle became as effortless as breathing. He watched as his fellow mages faded into history, leaving him alone in a world that no longer remembered their names.
When death finally claimed him, he thought his journey had reached its end. But fate—or something far beyond his understanding—had other plans.
Reincarnated into a foreign world, Zaphandor awakens within an ancient tower atop a mountain, overlooking the untamed Jura Forest. Stripped of his title, yet retaining his vast knowledge, he is left to uncover the mysteries of his new existence. With the All-Seeing Eye, an ability that allows him to comprehend and replicate any magic he witnesses, he begins to study the strange world around him, treating it as both a scholar and an observer. Until fate brings a strange slime into his domain…

Summary
What's up with the lack of Release that Witch fanfics!? Well, i wasn't liking how there wasn't many so i'm writing one! Basically, rimuru goes to the world of Release that Witch, he'll be replacing Roland Wimbledon as the 4th prince and as you might expect, he will be the new prince in charge of border town.
I'm really passionate about this one as it's combining two of my favorite Manga/Light Novels.
I don't own anything other than the story. Also, i'm porting this over from Wattpad due to issues over there; expect me to rarely upload lol.

The Rise of Ultima, Time Unwound by Lilaphine

Summary
Rimuru was trapped at the End of Space and Time after Yuuki annihilated all of existence. To make matters worse, Yuuki did something that prevented Rimuru from simply traveling back in time. With everything and everyone he cared about gone, other than his ever-faithful manas, of course, Rimuru slept for many years. Eventually he wakes up and Ciel proposes a way to time travel anyways. Knowing the risks, they do it.
At the dawn of existence Rimuru wakes up in the Underworld, only to discover his body was no longer his own. Instead, he (or was it 'she' now?) was now Ultima, the violet primordial demon. With no way to undo what has already been done, the former slime decides to live out their new life, hoping that one day the timeline will come full circle and she can reunite with her friends, and perhaps save those who were lost. But hey, Diablo and the two demonesses should be around here somewhere, right? Maybe she can get a head start.
Let's just hope the personality changes don't cause too many problems. Who knew becoming a demon would cause so many dark urges?
[Summary: Rimuru travels back in time and becomes the violet primordial.]

Summary
Rimuru was forced to become stronger to beat the odds soon after reincarnating as a slime. Now that he is stronger, though, the world has to deal with the fact that this has created a being that can't be overcome.
Takes place post-series, particularly using Light Novel canon. Since the Light Novel is only up to Volume 20 at time of writing, not everything about Rimuru's eventual powers are currently known, so this work may take liberties with regards to the unknown scope of post-series Rimuru's abilities.
