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!

The day has finally come for the Tempest Founder's Festival to kick off! From live concerts to incredible feats of monster engineering (and most of all, the massive labyrinth), revelers are sure to have their minds blown. And who should decide to participate in the battle tournament than the hero himself, Lightspeed Masayuki?!

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!

Having easily thwarted the Eastern Empire's invasion, Rimuru wishes to end the conflict once and for all and therefore heads for the imperial capital to take out the source. Meanwhile, Yuuki has worked his way up inside the Empire with the intention to stage a coup d'etat and usurp the throne. Rimuru, however, comes to find that the Empire's true power is on a whole other level from what he's seen so far...

Threatened by Tempest's rapid expansion, the Eastern Empire finally begins to strike back. According to Chloe, the time-traveling Hero, there exists a timeline in which the Empire defeats Rimuru and Tempest subsequently collapses. While Rimuru's doom isn't set in stone, his victory isn't a foregone conclusion either. And to make matters worse, an Empire spy seems to have infiltrated Tempest...

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...

After a fierce battle, Veldora has fallen into the enemy's clutches, and Rimuru is furious. The order comes down to unleash a massacre, and Benimaru and the other Tempest executives couldn't be more thrilled. The fuse has been lit for the final battle between Tempest and the Eastern Empire. But if he wants to save Veldora, Rimuru will need to evolve even further. It's time to release the power he's been holding back!

After a furious battle with the orcs, peace has once again returned to the Forest of Jura. Rimuru may be heading up the Great Forest of Jura Alliance, but he's mostly worried about finishing his town...until a visit from King Gazel Dwargo of the dwarves turns everything upside down. Not only that, but he's about to have a run-in with an exceptionally dangerous demon lord. What's a slime to do?!

Rimuru has emerged victorious in the war against the Eastern Empire, but between the ultimate skill Michael hijacking Emperor Ludora’s body and the mystic lord Feldway’s secret machinations, he still has a lot left on his plate. Plus, a recent fight at the labyrinth―which occurred while Rimuru was busy with his own climactic battle―revealed serious flaws in Tempest’s defenses.

Now that he’s finally got a moment to breathe, it’s time for everyone’s favorite slime to address some major infrastructure issues with his team…

Living alone and never having had a girlfriend, 37-year-old Satoru Mikami is dissatisfied with how his life has turned out. But after dying at the hands of a robber, he awakens to a fresh start in a new world...as a slime monster.

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!

Newly-minted Demon Lord Slime Rimuru has received word of a special assembly of all the demon lords, known as the Walpurgis Council. It just so happens that the topic of this year's meeting is how best to punish Rimuru for assuming his new demonic title... Will this hotshot slime go and crash this council himself?!

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...

The Empire deploys a vast army over 900,000 soldiers strong to invade the Forest of Jura. In response, Ramiris evacuates Tempest's inhabitants into the Dungeon for safety. While Primal Demons Testarossa and Ultima duke it out with the Empire on the front lines, the rest of the imperial army attempts to invade Ramiris's labyrinthine shelter. Little do they know, however, that the only thing they'll find there is a devastating bloodbath courtesy of Tempest's own mighty forces...

Framea's all-expenses-paid tour of Tempest continues, along with her never-ending search for three-star delights! But unfortunately for her, she's about to hit a major roadblock-three know-it-all demonic tourists! Now instead of seeing the sights herself, she's stuck guiding these newcomers around, and they're about to become more trouble than they're worth...

The Jura-Tempest Federation is a vast melting pot of monsters from all walks of life, and they're finally making waves in the wider world around them. Their leader, Rimuru, decides it's time to compile a Tempest guidebook-and there's no one better for the job than a local rabbitfolk girl with a knack for travel reviews! Follow her adventures in this unique That Time I Got Reincarnated As a Slime spin-off where you'll see the sights and learn the customs of this massive monster nation!

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...!

After Ramiris's match-fixing scheme and leaking of Framea's photos to the Shion and Shuna fan club, he's in big trouble with Rimuru. But our resident demon lord isn't getting off scot-free either, as his nightly romps have also come to light, and his allowance is dropping lower by the minute!

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...!

Framea's adventures in Tempest have only just begun, and she's already experiencing so many new wonders! Tasked with writing a guidebook to help introduce visitors to each of Tempest's many attractions, Framea finds herself visiting workshops, hot springs, and even venturing into labyrinths, all in the name of promoting tourism! All that's left now is to finish the book and unveil it, but an unforeseen obstacle bars her path...

After having a little too much fun collecting data for the next volume of her guidebook, Framea finds herself penniless with little income to speak of. After consulting her boss, Rimuru, he decides to let her use his card in place of the money she lacks. But after her initial reluctance to spending his money, Framea starts seeing brand-new, three-star cuisine and clothes, and she just can't say no! As she begins to worry about her reckless spending, the kingdom's greatest troublemakers pay her a visit...

Ever since Framea, a rabbitfolk girl, stepped foot into Tempest for a visit, her life's gotten way more exciting! Her analytical abilities have gotten her a gig as the land's official guidebook writer, working under the mighty demon lord Rimuru! But after being away from home for so long, her father's come to take her back, and her boss just might be tagging along...

Now that Framea's first guidebook to Tempest and all its cuisine, shops, and activities is done, she's on to her next adventure-school! At Rimuru's suggestion, she enrolls in the Tempest Technical Development Academy, where she's sure to have all sorts of new experiences to write about!
