That Time I Got Reincarnated as a Slime: Clayman's Revenge

Now that things have mostly been settled with Hinata, its time for Rimuru to announce his rise to Demon Lord to the world. Thus, Tempest prepares to hold a ceremony, inviting other countries to attend. Will the nation of monsters be able to convince people to respect its right to exist and its leader, though? It certainly seems like Rimuru has his work cut out for him.

The Tempest Founder's Festival is finally over-but now the bills are due! With all the human merchants refusing to accept the monsters' currency, it looks like trouble for the monster kingdom until a handsome nobleman offers them a loan. Or is this seeming generosity just a trap set by the secret leaders of the human nations, the mysterious Five Elders? Meanwhile, a party of skilled adventurers forces Rimuru to defend his dungeon personally!

The slime hits the big-time! Rimuru and his closest allies are invited to the kingdom of Engrassia to speak to the prestigious Council of the West. Will their plans come true, and Tempest, the monster kingdom, be allowed a seat among the human nations? But Maribel the Greedy-the mind-controlling heir of the all-powerful Rozzo family-won't let Rimuru's new country stop her plans for domination. And arrayed against them are not just Maribel's psychic powers, but high-tech weapons brought from another world...!
