That Time I Got Reincarnated as a Slime

Rimuru entrusts the children's education to a new teacher and returns to Tempest. After being updated on the events that transpired during his abscence, Rimuru starts negotiations to establish diplomatic relations with the Kingdom of Eurazania, led by Carrion.

The negotiations between Tempest and Eurazania are successful and both countries begin exchanging technologies and establishing trade routes. Some time later, Rimuru pays a visit to Gazel in the Kingdom of Dwargon, unaware that Clayman is preparing another scheme against him and his nation.

A meeting with King Gazel and a speech to the people following the declaration of mutual friendship with the Armed Nation of Dwargon. After completing these two major tasks, Rimuru slips out from Shuna's and Shion's sight and triumphantly heads to "that paradise," which he once promised to Gobta.

In Tempest, preparations were underway for a banquet before Rimuru's return. But then came Myurran, a demon sent to infiltrate Tempest as a sentinel for Demon Lord Clayman. She accompanies Youm's group as a military advisor, and upon entering Tempest, she is surprised by the power of the country, and deepens her relationship with the inhabitants. At the same time, King Edmaris of the Kingdom of Falmuth, who finds Tempest an eyesore, colludes with the Holy Church of the West and plans to invade Tempest.

Myulan takes action under Clayman's direction. And then another force - three Otherworlders sent by the Kingdom of Falmuth - turn on Tempest, where the Chancellor is absent.

As Tempest is attacked, an assailant appears in front of Rimuru. It is Shizu's other student, the strongest Holy Knight, Hinata Sakaguchi.

In a desperate attempt to escape from Hinata, Rimuru uses a skill, Gluttony, and Rimuru's fate is sealed. At the same time, Tempest is enveloped in a cloud of smoke and blood...

Rimuru learns of the plans of Clayman and the Kingdom of Falmuth. Rimuru lost the lives of his friends and the warmth of his daily life, and as he lay in the depths of his despondency, he heard the unexpected words of Eren.

In order to revive Shion and others, Rimuru reveals to his friends his past as a human being.

The battle for retribution has begun. Benimaru and the others carry out their respective missions. Hakurou's group challenge Shogo and Kyoya to battle once again. And then, Rimuru's wrath envelops the army of Falmuth.

The "Evolution to become a True Demon Lord (Harvest Festival)" is here, Rimuru, who has secured the necessary amount of souls for evolution was put into an intense sleep. Rimuru summons a demon to capture an enemy who had escaped.

Tempest has successfully revolved against the Kingdom of Falmuth but more threats arises. In the midst of this, Raphael has good news that it has successfully analyzed the Infinite Prison.

After saving his city and inhabitants, Rimuru brings back a very important figure to the people of the Great Forest of Jura. The end of the war between Falmuth and Tempest leads to the next step: reorganizing forces and treaties.

Although unforeseen, Rimuru opens a meeting with great leaders from various nations to discuss the steps that will follow the birth of a new Demon Lord.

After certain unforeseen events, the conference between monsters and humans continues and the leaders of the nations involved will know the steps that will follow the birth of a new Demon Lord and the return of the Dragon of the Windstorm.

Ramiris finally exposes the dire news about Tempest's future, about which he came to warn Rimuru. The confusion is soon resolved, but the situation can be dangerous for other reasons. Everyone then comes together to try to predict Clayman's plans.

The announcement of the upcoming event that will bring together several Demon Lords serves as part of the plan to face Clayman. But before that, Rimuru must find a way to save the people of Eurazania, who have become the target of a diabolical plot by Clayman.

After sending his troops towards Eurazania, Rimuru needs to prepare for the Walpurgis, the great gathering of Demon Lords - and also for the confrontation with Clayman for what he has been doing.

Benimaru is in command of the troops that will face Clayman's army, which invaded the Animal Kingdom. If everything goes according to plan, achieving victory is just a matter of time.

Gabiru and the Three Beast Warriors battle Clayman's forces until they encounter formidable opponents. Benimaru will have to take action.

On the other side of the front, Shuna, Souei and Hakurou must face Adalman, one of Clayman's most powerful subjects.

The long-awaited feast of the Demon Lords begins, and Clayman serves the first course: a hate-filled, accusation-filled speech to put Rimuru against the wall.

Veldora's sudden appearance surprises Rimuru, but this saves him from Milim's attacks. It's time to try to end the battle against Clayman.

Clayman awakened as a true demon lord. The fight between Rimuru and the puppet master continues, but the difference in strength is very evident. The battle and its aftermath bring profound changes to the Ten Demon Lords.
