Summary

That Time I Got Reincarnated as a Slimeintroduced some new characters in its latest episode, expanding the already large cast even further. At the very least, this gave Rimuru a chance to demonstrate the power of his underlings, thereby earning the respect of some of Jura Forest’s strongest residents.

The big day of the festival has nearly arrived, and with it comes some familiar faces returning. Milim showed up to the dungeon that Ramiris and Rimuru were creating, and demanded to be a part of the plan. Fortunately, Milim did have something of value to contribute, and has been tasked with capturing some elemental dragons to help make the dungeon even tougher than before. The episode also saw the beginnings of Rimuru’s official duties, welcoming parties of representatives who have traveled a long way to pay tribute to their new Demon Lord. Of course, some of these representatives were a little more formal than others.

What Happened in That Time I Got Reincarnated as a Slime Season 3, Episode 15?

Rimuru Meets the Sons of Daggrull

Episode #15 ofThat Time I Got Reincarnated as a Slimeseason 3saw Milim arrive and join the efforts to construct Rimuru’s massive 100-floor dungeon, and she was tasked with capturing elementally-aligned dragons to incorporate into the design of the dungeon. Milim, as usual, is just eager to help out and be a part of things, and so eagerly agrees. Rimuru also welcomed his merchant friend Mjollmiles to town, after paying him a visit a few episodes ago. Mjollmiles was attacked on the way into town, forcing Rimuru to put the road patrols on high alert for further incidents.

With the dungeon’s construction well underway, Rimuru was able to finally begin his official duties, holding a formal audience with those who’ve traveled such a long way to greet him. Among the traveling groups were some familiar faces, such as Gabiru’s father and leader of the lizardmen/dragonewts, and some of the Dryads who live in the forest. Rimuru also had some unexpected guests, as a trio of brothers broke through Shuna’s barrier and entered town. After having Shion teach them a lesson, Rimuru learned these were the sons of Demon Lord Daggrull, sent to train under his leadership. Rimuru dumped that responsibility on Shion, too, however.

The sons of Demon Lord Daggrull arrive in Tempest.

That Time I Got Reincarnated as a Slime Season 3, Episode 16 Meets the Tengu

Rimuru Meets the Most Difficult Group to Deal With

Episode 16 is entitled “Benimaru’s Ordeal.” Episode 15 adapted a large chunk of chapter 106 of the manga, skipping over most of chapter 105 in the process. With the introduction of the Tengu at the end of the episode, however, it seems likely that episode 16 will go back to chapter 105 and explain the attempts at negotiation with these isolated people. As it turns out, the Tengu have quite a few surprises to share, particularly as it relates to the Oni likeBenimaru and Hakuro. With these shocking surprises in store, will it even be possible to negotiate a proper treaty with the Tengu, or is it all a lost cause?

The episode will likely also see Diablo and Hakuro return from the Kingdom formerly known as Falmuth, now that Youm has been installed as its new King. Hakuro’s presence is particularly necessary, due to his surprising ties to the Tengu. Fans can also expect that, as Rimuru began to grow suspicious of the Elven slave trade he heard whispers of, he’ll start taking action to do something about this blatant crime, especially now that he knows those Elves were being taken from the Great Forest of Jura.
