That Time I Got Reincarnated as a Slime season 3 episode 24 begins with Mjollmile trying to calm the irritated merchants, who accuse him of scamming them. He apologizes to the merchants and says that he can pay them anything but the dwargon gold coins they want.

Amid the chaos, Duke Meuse joins the scene and assures the merchants that the monster nation won't put their debts onto them. He believes Mjollmile and the Jura Tempest's executives can put the merchant's mind at ease by providing them with the Dwargon gold coins.

The narrative for That Time I Got Reincarnated as a Slime season 3 episode 24 shifts to Rimuru Tempest, who enters the room, accompanied by his executives. Duke Meuse, who is originally sent by the Rozzos family, grins in delight because he feels the Demon Lord won't be able to satisfy the merchants and make a mockery of himself.

However, his plan is spoiled, as Rimuru puts the authentic gold coins from Dwargon on the table. The Demon Lord even brings the international reporters, who capture the scene and take notes. After clearing everyone's payment, the Slime reveals he won't ever do business with them, since they wanted to sully his nation's name.

While it's only fair to ask for the internationally accepted Dwargon gold coins, Rimuru reminds everyone that their nation hasn't joined the Council yet. Moreover, he plans to build their own new giant economic bloc. Thus, there's no reason for them to join the council.
