That Time I Got Reincarnated as a Slime Novel Series by Fuse, Mitz Vah, 伏瀨

Lonely thirty-seven-year-old Satoru Mikami is stuck in a dead-end job, unhappy with his mundane life, but after dying at the hands of a robber, he awakens to a fresh start in a fantasy realm...as a slime monster! As he acclimates to his goopy new existence, his exploits with the other monsters set off a chain of events that will change his new world forever!

37-year-old Satoru Mikami got a new lease on life when he was reincarnated into another world...as a slime named Rimuru Tempest. But with the help of his wits, his newfound powers, and a little luck, he's started building a cross-species village of goblins, direwolves, and dwarves! Rimuru doesn't know it yet, but his arrival is bringing major changes to his new world...

TIMES ARE CHANGING FOR THE WORLD!After a furious battle with the orc lord, peace has once again returned to the Forest of Jura. Rimuru may be heading up the Great Forest of Jura Alliance, but he's most worried about finishing his town...until a visit from King Gazel Dwargo of the dwarves turns everything upside down! Not only that, but Rimuru is about to have a run-in with Milim Nava, an exceptionally dangerous demon lord known as the "Destroyer." What's a slime to do?!

Rimuru is gaining more and more power with his monster country, especially now that he has demon lord and dwarf allies. But then he has a dream about Shizue-a grief-stricken plea to save her former students...

Despite Rimuru's absence, Tempest was as peaceful as always. Well, as peaceful as a monster town called "Tempest" could get, anyway. But that was only until they learned that a bunch of heavily armed humans were coming their way. To make matters worse, the Beast Kingdom of Eurazania has declared war on Milim, and Rimuru is nowhere to be found...!

A meeting of demonic minds!Newly minted demon lord Rimuru has received word of a special assembly of all ten demon lords known as the Walpurgis Council. It just so happens that the topic of this particular meeting is how to best punish Rimuru for assuming his new title without their permission... moreA meeting of demonic minds!Newly minted demon lord Rimuru has received word of a special assembly of all ten demon lords known as the Walpurgis Council. It just so happens that the topic of this particular meeting is how to best punish Rimuru for assuming his new title without their permission. Fortunately, he's got friends in high places who are willing to vouch for his authenticity, and this council could be the perfect opportunity to get revenge on the demon lord Clayman for the violence he brought to Tempest. Is this blobby big shot cunning enough to kill two birds with one stone? less

News of demon lord Clayman's defeat by Rimuru shakes the Holy Empire of Lubelius to its core, especially since the Chief Knight of their Holy Imperial Guard, Hinata Sakaguchi, had once attacked Rimuru not long ago. In an attempt to avoid total warfare at all costs, Hinata shoulders the blame for all the bloodshed and decides of her own accord to head for Tempest...!

It's festival time in Tempest, and this exuberant ectoplasm knows how to throw a party! After reconciling with Hinata and securing his title as demon lord, Rimuru's pulling out all the stops to hold a massive bash in his nation of monsters, along with a little help from his many friends and allies!

AN EVENT OF MONSTROUS PROPORTIONS!The Tempest Founder's Festival is in full swing, with Rimuru and all the monsters under him keeping busy setting up the attractions. From live concerts to incredible feats of monster engineering (most notably, the massive dungeon), revelers are sure to have their minds blown... moreAN EVENT OF MONSTROUS PROPORTIONS!The Tempest Founder's Festival is in full swing, with Rimuru and all the monsters under him keeping busy setting up the attractions. From live concerts to incredible feats of monster engineering (most notably, the massive dungeon), revelers are sure to have their minds blown. But all eyes are on the main event-the First Tempest Battle Tournament-and who should decide to participate but the Hero himself, Lightspeed Masayuki! What will come of his chance encounter with the demon lord Rimuru? less

The Tempest Founder's Festival was a roaring success, and Rimuru's next goal is to join the infamous Council of the West. However, a certain influential figure within the Council has no intention of letting someone as powerful as Rimuru have a seat at the table, and they will stop at nothing to quietly snuff him out before he makes any moves!

A RACE AGAINST TIME​Rimuru and his team are headed for the Holy Empire of Lubelius to organize the concert he promised Luminus, its leader. But as preparations continue, a fiendish conspiracy involving both demon lords is being laid out behind the scenes. There may not be much time for music after all…especially with a third demon lord on the hunt for a certain otherworlder in Rimuru’s care!

ABANDON HOPE, ALL WHO ENTER HEREThe Eastern Empire’s vast army (over 900,000 strong) is ready to invade the Forest of Jura. Thanks to Ramiris’s mind-boggling powers, Tempest’s entire capital—buildings, inhabitants, and all—has been evacuated into the nation’s labyrinthine Dungeon. While Primal Demons Testarossa and Ultima kick some serious imperial butt over on the front lines, the rest of the Empire’s army attempts to storm the Dungeon... moreABANDON HOPE, ALL WHO ENTER HEREThe Eastern Empire’s vast army (over 900,000 strong) is ready to invade the Forest of Jura.
