WHEN IT RAINS, IT POURS! Despite Rimuru's absence, things seem to be proceeding fairly smoothly in the newborn nation of Tempest. But there's trouble brewing elsewhere: The nearby Kingdom of Farmus's top brass are planning an invasion of Tempest, and at the same time, Rimuru's demon lord friend Milim Nava has declared war on Tempest's ally, the Beast Kingdom of Eurazania. As if things couldn't get any worse, all communication between Rimuru and his crew back home has suddenly gone silent in their hour of need! Tempest may be in for some hard times ahead-but this steadfast slime isn't throwing in the towel just yet. He has a plan...and it's downright demonic!

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!

NO REST FOR A NATION-BUILDING SLIME! Now that Rimuru's monster-centric town has blossomed into a bona fide independent nation, it's time for his next step: build and maintain diplomatic relations with nearby countries! With a group of his trusty monster pals, Rimuru travels to the Beast Kingdom of Eurazania and the Dwarven Kingdom to meet with their respective heads of state and represent his domain as best as a slime possibly can. As if there wasn't already enough on Rimuru's mind, the otherworlder Shizu has been visiting him in his dreams, begging him to save her former students. Looks like that'll be another stop on this pliable pioneer's itinerary...

AN INSATIABLE GREED The Tempest Founder’s Festival was a roaring success, and after working out a few kinks, the Advanced Dungeon is proving to be a major Tempest tourist attraction. Now Rimuru’s next objective is to join the infamous Council of the West—however, a certain influential figure working from the shadows of the Council has no intention of allowing someone as powerful as Rimuru to take a seat at the table, and she will stop at nothing to quietly snuff him out before he makes any moves!

Let the good times roll!It’s festival time in Tempest, and this demon slime knows how to throw a party! After reconciling with Hinata and the Western Holy Church, Rimuru’s pulling out all the stops to prepare a massive bash in his nation of monsters—with a little help from his many friends and allies! It’s the perfect opportunity to debut his new demon lord title while showing the world everything the Jura-Tempest Federation has to offer. Will this big event go off without a hitch?

As players of Monster Hunter and Dungeons & Dragons know, the slime is not exactly the king of the fantasy monsters. So when a 37-year-old Tokyo salaryman dies and wakes up in a world of dragons and magic, he's a little disappointed to find he's become a blind, boneless slime monster. Mikami's middle age hasn't gone as he planned: He never found a girlfriend, he got stuck in a dead-end job, and he was abruptly stabbed to death in the street at 37. So when he wakes up in a new world straight out of a fantasy RPG, he's disappointed but not exactly surprised to find that he's not a knight or a wizard but a blind slime demon. But there are chances for even a slime to become a hero...

A gutsy glob in crisis! News of the demon lord Clayman’s defeat by Rimuru shakes the Holy Empire of Lubelius to its core—especially since the chief knight of the nation’s Imperial Guard and captain of the Crusader forces, Hinata Sakaguchi, launched a bold attack on Rimuru not long ago. Things look only more dire when a priest sent by Rimuru to attend an urgent meeting of Lubelius bigwigs ends up murdered. The stakes couldn’t be higher for either side as Hinata heads to Tempest to settle things—one wrong move could spell total warfare!
