What Happened in That Time I Got Reincarnated as a Slime Season 3, Episode 12?

Festival Preparations Are in Full Swing

In That Time I Got Reincarnated as a Slime episode 12, Rimuru checked in with the progress of festival preparations, as invites were being sent out to VIPs from around the world. Rimuru then took a quick trip to Engrassia with Shuna, where they managed to convince a patissier otherworlder to come to Tempest and create sweet treats for the festival. The next stop for Rimuru was the Kingdom of Blumund, where he met with Mjöllmile, who was trapped in a meeting with a corrupt noble when Rimuru arrived. Mjöllmile kicked out the noble when he was rude to Rimuru, and the two quickly got down to business discussing the festival.

Mjöllmile suggested that the festival feature theatrical performances, as well as an arena for combat sports to take place. Rimuru was enthusiastic about these ideas, and they spent a good deal of time on the logistics of such an undertaking. Rimuru later paid a visit to guildmaster Fuze, giving him an invitation to the festival as well as one for Yuuki Kagurazaka, knowing that the busy guild leader might not be able to attend.

That Time I Got Reincarnated as a Slime Season 3, Episode 13 Sends Invitations for All Nations

Rimuru Gets a Visit from Ramiris

Episode 13 of That Time I Got Reincarnated as a Slime season 3 is entitled “Invitations for All Nations.” Rimuru has already gotten started on the process of delivering invitations to VIPs across the continent, and it seems that will only continue into the next episode. Based on chapter 103 of the manga, fans can expect to see the Fairy of the Labyrinth, Demon Lord Ramiris, making an appearance, as she decides to move to Tempest unexpectedly, hoping to bring a little more excitement into her life. Rimuru will be less than enthused, at first, until he gets an idea from Ramiris’ power.

Ramiris can create labyrinthine dungeons, giving Rimuru the idea to set up a dungeon raid as one of the activities that adventurers can partake in during the festival. Thanks to Ramiris’ magic, no one will be at risk of dying in the labyrinth, so they can fill it with all sorts of monsters–and maybe a certain Storm Dragon at the end. The dungeon will also have plenty of powerful treasure and loot, of course, making it the perfect temptation for any traveling warriors who might hear of Tempest’s founding festival.

Episode 12 also marked the debut of a new opening and ending theme for That Time I Got Reincarnated as a Slime, signaling the end of one arc and the beginning of another. These peaceful arcs about developing Tempest can be among the most endearing moments of the series, and aspects like the dungeon and the arena tournament should ensure that there’s still plenty of action for That Time I Got Reincarnated as a Slime fans who are more here for epic battles.
