With the Falmuth army decimated, Rimuru’s transformation into a Demon Lord finally begins. A successful evolution would mean unlocking new powers and a chance to resurrect the dead, but as Rimuru and his followers are forced into a deep sleep, the future is all but certain. Fortunately, the mysterious demon Rimuru summoned has every intention of seeing his master return as the slime he always was, no matter the cost…

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!

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!

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...

ABANDON HOPE, ALL WHO ENTER HERE The 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. Little does the enemy know, however, that they’re about to face a devastating bloodbath at the hands of Tempest’s own mighty forces...

AN EVOLUTIONARY TRIUMPH Following a fierce battle against his sister Velgrynd, Rimuru’s steadfast ally Veldora has fallen into the enemy’s clutches. An enraged Rimuru gives the order to massacre his foes, a request his Tempest top brass couldn’t be more thrilled to oblige. Once Rimuru’s demon underlings evolve en masse, the final battle between Tempest and the Eastern Empire will begin in earnest. But if Rimuru wants to save Veldora, he’ll need to undergo an evolution of his own. It’s time to unleash the power he’s been holding back!

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!
