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!

BACK TO THE WALL At the climax of the Walpurgis, Clayman’s schemes are exposed, and he resorts to desperation. Although Rimuru is firmly in command, this is unlikely to be the end of the Moderate Harlequin Alliance. Meanwhile, the truth about a certain vampiric Demon Lord with connections to the Holy Church are sure to complicate matters for Tempest. The origins of Luminism are finally revealed!

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?

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 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!

Rimuru and his forces fight heroically on all fronts to stop Michael’s plan...only to lose the demon lord Leon to Feldway’s schemes. Michael’s next target is Masayuki the Hero, who possesses the soul of Ludora, Michael’s former host. There to meet him in battle are the paladin Hinata, the Primal Demon Blanc, and Velgrynd the Flame Dragon. But just when Michael begins to set things in motion, the situation devolves even further into chaos...

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…
