That Time I Got Reincarnated as a Slimeepisode #21 featured the Tempest opening festival in full swing, with a major concert performed that won over even the likes of Luminus Valentine, as well as the long-awaited arrival of the arena’s opening. Rimuru also discovered that the country has a bit of a liquid asset problem, which may make paying for the festival a real problem.

The episode dealt with a wide range of characters and issues, most notably featuring Shion and Shuna showing off their previously unknown musical talents for all the world to see. While the scene was quite a bit shorter than its manga counterpart, it was still an enchanting performance, and it is, of course, nice to actually be able to hear the music that they’re playing at long last. Luminus was so impressed by the concert that she arranged for an advanced cultural exchange with Tempest, even providing Rimuru with a powerful new skill. Here’s how to tune in and catch episode #22 when it debuts.

There was also a scientific presentation, showing Tempest’s study of Magicules and how they interact with even non-living objects, stunning many academics in attendance.

Later on, Rimuru had a meeting with Mjollmiles and many of his other most trusted associates, where it was revealed that Tempest might be having a problem paying its debts. While the nation is rich in treasure, it has little in the way of actual currency, making it difficult to pay smaller merchants the appropriate amount. The idea was floated to overpay a bit in raw gold, rather than coins, but Mjollmiles objected vehemently, claiming this would set a bad precedent. The situation seems to have been orchestrated by the merchant’s council, hoping to damage Tempest’s plans for a “co-prosperity” zone.
