That Time I Got Reincarnated as a Slime is a reincarnation anime that is a huge hit, on par with Overlord. It also has spin-off works and is a very solid story about the success of the main character, a slime named Rimuru Tempest. As the slime grows stronger and stronger, one day he learns of the existence of a demon lord. This demon lord is not necessarily evil, but actually exists as a deterrent to prevent humans from becoming arrogant. In this article, we will introduce Karion, one of the demon lords who appears early in the story.

A beastman nicknamed the Lion King, the king of Usurania. Usurania is a country inhabited by beastmen, with an abundance of fruits and berries that have been improved over generations, allowing them to produce even higher quality produce. They are also very faithful to the monster teachings of survival of the fittest, with powerful figures such as Karion living in luxurious buildings and the people living simple lives, but they seem to have no complaints, as if this is exactly how they wanted it. Also, as you'd expect from beastmen, there are many soldiers with great fighting ability. The envoys who tried the fruit wine in Tempest were captivated by its deliciousness and began trading fruit.

Demon Lord Karion first appears in the series after Rimuru's plot to turn Gerudo into a Demon Lord is foiled. Karion, along with Clayman and Milim, is involved in the plot, and it is there that he learns about Rimuru. Along with Frey, who was unaware of Rimuru's scheme, the group becomes interested in Rimuru and abolishes the non-aggression treaty in the Great Jura Forest. At this point, the three Demon Lords don't know about Milim's conditions for abolishing the non-aggression treaty, or rather, they haven't even thought about it. Compared to Milim, Clayman, Karion, and Frey are still newer Demon Lords. Incidentally, they are apparently roughly the same age as Frey.

Milim suddenly attacks Usurania. This is before Rimuru becomes the Demon Lord. At this time, Milim pretends to be manipulated by Clayman and attacks Karion. It was Clayman's plan, but Karion is prepared to fight back. However, he is taken out in one hit by Milim's Drago Nova. At this time, Clayman thinks he has killed Karion, but in fact he is still alive. Why is his strength so different despite him being a Demon Lord? It's because Demon Lord Karion (Frey, Clayman) is not an awakened Demon Lord. Incidentally, Milim became an awakened Demon Lord a long time ago. As was the case when Rimuru fought Clayman, the difference in strength between an awakened Demon Lord and not is like night and day.

At Walpurgis, when the protagonist, the slime Rimuru, becomes an awakened demon lord, Clayman plots to pin all the blame for Karion's murder on Rimuru. Unfortunately, however, all of his plans fail due to Milim's pretending to be manipulated. Demon Lord Karion is actually alive at the time, and appears alongside Frey. In That Time I Got Reincarnated as a Slime, there are many scenes like this where someone seems dead or seems to be being controlled. Leaving that aside, after Rimuru successfully kills Clayman, Demon Lord Karion, realising he is not strong enough, decides to join Milim's forces. Just as you'd expect from the beastmen's survival of the fittest mentality. At that time, Frey also joins Milim's forces.

Karion is trained by Milim. The opportunity to test his skills is at the martial arts tournament held in Tempest. Former Demon Lord Karion dons a mask and enters the main event. In the cheering section is Milim, also in disguise. He must win at all costs! Karion is fired up to fight, thinking about the punishment he will exact if he loses. But his opponent is Diablo. Unfortunately, he is easily defeated. Milim is now tasked with training him to become even stronger. The sense of formidable opponent he seemed when he first appeared is nowhere to be seen.

Karion has spent countless hours with Milim's training partner. Seeing him during his training, he was called a genius. That person was Gobta. As a Hofgoblin, Gobta's magical energy reserves are low, but he is able to merge with Ranga, and Milim instructs him to shift his training to thoroughly develop his senses. Karion fought alongside this genius Gobuta (and Ranga) in the battle against Vega. At first, Karion struggled alone, but Gobuta joined the fight. During the battle, Gobuta taught him how to super-recover. Karion then brilliantly defeated Vega.

【That Time I Got Reincarnated as a Slime】Why Former Demon Lord Karion Is So Unhateable

The reason why Demon Lord Karion is so unhateable is probably because he's a complete muscle-brained idiot and completely terrified of Milim. After the war, he and Milim visited Tempest together, hiding from Frey, and it seems like they have a good relationship. Furthermore, even during his time as Demon Lord, Karion has always had a straightforward personality, and his negotiations with Rimuru and discipline of Fabio were both very clear. Perhaps it's precisely because of this that Karion is so lovable.

[That Time I Got Reincarnated as a Slime] Demon Lord Karion Summary

Is this the kind of person he is? Since the Demon King is a beastman, this work's definition of the Demon King is distinct from that of the demon kings depicted in typical stories. His role as a mediator. Demon King Karion likely wasn't aware of this, but he simply pursued martial arts, and when he was crushed, he had the generosity to humbly join the defeated enemy. Perhaps this is something we should all learn from as men. Karion, who seemed poised to be a loser, was ultimately able to win the battle against Vega, which was a truly wonderful event.
