After a light-hearted banter in That Time I Got Reincarnated as a Slime season 3 episode 1, Diablo tells Rimuru about the task he was assigned while he was away. The Demon butler, accompanied by others from the Jura Tempest, had to reach Falmuth with the prisoners.

However, he realized that Shion had gone "overboard" with the captives, reducing their existence into meaty flesh. With his special magic, he restored Razen and others to their original form. They pledged their loyalty to Rimuru and promised to support their cause.

Razen realized that the Kingdom of Falmuth had awoken a sleeping lion in Rimuru Tempest. At the same time, he understood the power Diablo possessed. As such, it was a no-brainer for him to pledge his alliance.

Similarly, the King of Falmuth felt he was in no position to continue the war. Interestingly, Diablo thought of a plan. After arriving at the Kingdom of Falmuth, he instructed Razen to devise a false narrative for the nobles to ensure they thought highly of Rimuru Tempest.

The Falmuth sorcerer told the nobles that their forces were demolished by a slumbering dragon that was awakened due to their battle. Sir Reyhiem, the archbishop of the Western Holy Church arrived and added that if it weren't for Rimuru Tempest, they wouldn't have survived.

He also mentioned that Rimuru spoke to the slumbering dragon, Veldora, to calm him down. Following that, Razen informed them about how he had personally witnessed the town that the monsters had built.

Undoubtedly, the nobles were shocked to hear about Rimuru's exploits and realized they made a grave error in issuing a war against them. As such, they asked if they could come to terms.

Youm Farmenas revealed that although Rimuru sought a peaceful co-existence between humans and monsters, he wouldn't let slide the fact that many of his comrades perished in the war. As such, the Kingdom of Falmuth had no choice but to yield.

Once the nobles agreed, Diablo released the king and restored him to normal. He also revealed that there would be peace talks between the kingdoms in a week. The Demon butler then told the Falmuth nobles that they had to choose one of three options.

According to the first option, the king must abdicate and the nation has to pay for war reparations. For the second option, they must surrender to Rimuru's nation and become a vassal state. The third and the last option was to continue the war.

Before leaving the hall, Diablo firmly declared that if his kingdom didn't hear anything from Falmouth in a week, they would assume that Falmuth wished to continue the war.

After that, That Time I Got Reincarnated as a Slime season 3 episode 1 returns to the present. Diablo explains to Rimuru that Falmuth has no choice but to choose the first option. Neither do they have the means to continue the war nor would they want to become a vassal state.

At that moment, Rimuru Tempest feels that the nobles may choose a third party to pay off the war reparation amount.

Since the king will abdicate his throne, he will also lose his political foundation. As such, Diablo speculates that he might be forced to take responsibility for the crisis. In other words, he will become the "third party."

With everyone against him, the king could be forced to seek Youm's help, which means indirectly asking for Rimuru's aid.

That Time I Got Reincarnated as a Slime season 3 episode 1 ends with Diablo assuring Rimuru that if the next king allies with the neighboring kingdoms in the war, he will go to the battlefield himself.
