In the world of That Time I Got Reincarnated as a Slime, a game is being played between the hero Rudra and the first Demon Lord Guy, in which they use their pawns to fight for world dominance, and the winner must listen to what the other person has to say. Guy's pawns are the Demon Lords. The original role of the Demon Lords is to act as a deterrent to stop humans from becoming arrogant, in other words, as mediators. We would like to introduce you to one of the Ten Great Demon Lords, Frey!

Frey appears in the story after Gerudo is defeated by Lilm. When Clayman, Karion, and Milim's plan to create a new demon king ends in failure, the four of them, including Frey, gather together. The three lament the Demon Lord's failure, and take an interest in Rimuru, and the non-aggression pact with Jura Forest is abolished. Meanwhile, Frey has something on her mind. That is, the seal on Charybdis, which had been sealed away by the hero, is about to be broken. Frey, the Queen of the Harpies, knows that if the seal is broken, they will be caught up in a great disaster, and she is at a loss as to how to deal with it.

Just as Rimuru (Milim) successfully defeats Charybdis thanks to Clayman's strategy, Clayman mutters to Frey that he will repay her for this debt at Walpurgis. Walpurgis is one of the few treaties that bind Demon Lords, and is convened with the consent of Clayman and two other Demon Lords. Clayman was not an awakened Demon Lord, but he had secretly received the method to become one from Kazalim (chairman of the Moderate Clowns), and it is likely that Gerudo's transformation into a Demon Lord was also one of the experiments. Frey is basically uninterested in others, and Clayman must have thought that he was one of those people he could not bring in unless he did this. Incidentally, neither Clayman nor Frey are awakened Demon Lords.

In fact, Demon Lord Frey and Demon Lord Karion are from a fairly new generation of demon lords. Guy and Milim were the first generation, followed by Leon and Dino's generation, and then Karion and Frey. Although Clayman is a relatively new demon lord, he is a more veteran demon lord than Karion or Frey. That's why when the non-aggression pact was abolished, Milim said that it was no wonder he didn't remember because he was a new demon lord.

Clayman attacks Tempest. At the time, Rimuru is absent as he is fighting Hinata. At that time, Shion dies, and Rimuru kills all the soldiers to revive Shion and becomes an awakened demon lord. In the background to all this, Clayman had a plan to become an awakened Demon Lord through a bloody battle between humans and the monsters of Tempest, but it ended in failure. So they target Rimuru and open Walpurgis. Frey agrees to do so in order to repay the debt she owed him last time. And for some reason Milim also agrees, and Walpurgis is opened. Clayman and Frey seem to get along well, but it seems Frey actually did not like Clayman. In the end, she betrays Clayman, and he dies there.

During Walpurgis, Clayman is killed by Rimuru's Gluttonous King. After that, Guy says that Rimuru can call himself the Demon Lord. Everyone agrees, but then Frey looks at Guy and Milim and begins to make a request. He says he is too weak compared to the other Demon Lords, and at best is equal to Clayman. He also says that he cannot leave Milim alone and would like to become her subordinate. Karion then adds, saying that he was also defeated by Milim with one punch and that he would like to surrender to Milim's army. Milim ultimately accepts the two, Frey and Karion are expelled, and with Rimuru becoming the new Demon Lord, the title is changed from Ten Great Demon Lords to Eight Star Demon Lords.

After the final battle, the territory of the Celestial World becomes Milim's. The Tenma Clan also become Milim's subordinates. Many people have migrated from Milim's former territory, so Rimuru should be busy with general affairs and chores, but Milim and Dino sneak away from Frey and come over to hang out with him. After the two finish hanging out, Frey comes to pick them up, looking angry. Frey is probably the one who is mainly doing the chores. It's quite a tough role.

Frey is now under Milim's command. I was wondering what their relationship was, but it seems like they have built a good relationship. When Frey was seriously injured in a battle, Milim asks Rimuru to help Frey. Frey is the queen of the Harpies, and although she prides herself on being superior to Karion and Clayman in aerial combat, she quickly realized that she was no match for Milim, so she must be quite an analyst. Frey, a former demon lord with such a beautiful place, is probably busy with chores today as well.
