That Time I Got Reincarnated as a Slime

Tempest is thriving after the success of its festival, but unexpected trouble has arisen with the new dungeon.

Rimuru and his trusted companions discuss ideas for improving the dungeon.

Yuuki is saddened by the death of Clayman, and Luminus is saddened by the death of Roy. Steeped in sadness, and having lost their friends, they seek their next move against Rimuru, who has grown in power and become a true Demon Lord.

Expecting visitors from all races to come calling after learning that Rimuru now controls the entire Great Forest of Jura, Rimuru decides to hold a festival to introduce himself and Tempest to the world, with the goal of attracting new citizens.

Responding to Rimuru's concerns about monsters in the forest harming humans, Vesta and Kaijin reveal a new invention they hope will keep the road to Tempest safe. Also, Rimuru assigns a new task to Geld.

A war council led by Hinata is held in the Holy Empire of Lubelius. Moments after Hinata declares her intent to meet Rimuru and talk to him, she receives a hostile message from Rimuru.

The spread of false information causes the Temple Knights to assemble, endangering Diablo's plan to conquer Falmuth. Meanwhile, Rimuru learns that Hinata is on her way to Tempest.

As Hinata makes her way to Tempest, the ramen and well-built roads she sees along the way prove to her that Rimuru genuinely wants monsters and humans to coexist. But against her wishes, one of her men is also on his way to Tempest...

The Crusaders have reached Tempest, and the battle is on. Hinata lays everything she learned from her mentor, Shizu, on the line in a life-or-death showdown against Rimuru.

Diablo descends before the enemy, King Edward of Falmuth. Also present are Saare and Glenda, two of the three Battlesages who are regarded as the most brilliant among the Master Rooks.

Just after the end of Hinata and Rimuru's duel, Hinata's sword moves on its own and targets Rimuru. Hinata jumps in its way to protect him and is gravely injured. Then the masterminds behind the whole conflict show up...

The Seven Days Clergy have been purged, and the battle is over. Rimuru and Hinata hold a meeting to discuss future relations between their two nations, and the masterminds behind the whole conflict, the Eastern merchants, are revealed.

Everyone in Tempest is busy preparing for the festival to celebrate the country's opening. Rimuru visits Mjöllmile to share ideas on forms of entertainment that will keep people coming back for more.

Demon Lord Ramiris tries to argue her way into moving to Tempest, where there's great food, hot springs, and ample entertainment. Rimuru happens to walk into the argument and comes up with a way to make use of Ramiris's skills.

Rimuru is building a dungeon in preparation for the upcoming festival. It will feature treasure chests containing weapons made by Kurobe, and Veldora will inhabit the deepest floor as the final boss. Then Milim suddenly shows up with a suggestion...

Numerous representatives from across the Great Forest of Jura have assembled in Tempest to congratulate Rimuru on his appointment to Demon Lord. Shuna requests holding a three-day audience to meet with them.

On the last day of the audience, Rimuru meets Momiji, the representative of the Tengu clan. Their meeting comes after Rimuru had sent Benimaru to the Tengu village to request their permission to build a tunnel through the Kusha Mountains.

After learning about an elf slave trade, Rimuru had Soei investigate, but it turns out the slave traders have already been shut down by Masayuki, the Lightspeed Hero. Word is now spreading that the Hero is headed to Tempest to slay a Demon Lord...

After meeting with the kings of various nations, Rimuru heads to Engrassia to invite his former students to the festival. The kids are thrilled to go back with him to Tempest, but then the hero Masayuki arrives as well...

The night before the Opening Festival, Rimuru throws a lavish banquet for all the nobles and royalty visiting Tempest. When the party is in full swing, Empress Elmesia of the Sorcerous Dynasty of Thalion arrives, throwing everyone into chaos.

It's day one of the festival, and Rimuru finally gets to see all of his friends' performances and presentations. As he's enojying the festivities, he's summoned by Luminus...

The second day of the National Foundation Festival dawns, bringing with it the main round of the battle tournament. The fighters face off and give it their all—except for one, which causes Rimuru concern.

Gazel and Elmesia pledge to assist Rimuru with Tempest's lack of funding. Elmesia then proposes an alliance, but she's concerned about the danger Diablo poses.

Rimuru's dungeon is finally revealed, and his new ally Masayuki is among its first challengers. Later, after the festival is over, Rimuru's biggest job still awaits.

Rimuru pays the merchants with the gold coins he's procured. The merchants try to garner futher favor, but Rimuru ceases trading with them. Rimuru then gathers his allies and calls for action again the eastern merchants who are operating in secret.

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.

Mikami Satoru, a businessman, is stabbed by a criminal on the street and killed. When he regains consciousness in the darkness, he finds that he's been reincarnated as a slime! With nothing better to do, he spends his time devouring all the rare herbs and precious ores he comes across. As he does, he encounters the Storm Dragon Veldora, who was sealed in this cave 300 years ago by a hero's "Unlimited Imprisonment" skill. He's frightened at first, but as they talk, he becomes friends with the long-isolated Veldora.

The slime Mikami and the Storm Dragon Veldora decide to give each other names. Veldora gives the slime Mikami the name "Rimuru," and Rimuru comes up with a family name for both of them: "Tempest." Then Rimuru uses his Predator skill to take Veldora into his body and analyze the "Unlimited Imprisonment" seal in hopes of breaking it... but this action sends a shock through the nations surrounding the Great Forest of Jura. With Veldora gone, there's a chance that the larger nations could become bold and invade the smaller provinces. With no knowledge of this, Rimuru leaves the cave and meets some Goblins.

After leaving the cave, Rimuru encounters a village of Goblins under attack by a clan of Direwolves. Caught in the heat of the moment, Rimuru agrees to help the Goblins in their battle. That night, the Direwolves arrive to try to take over as the new rulers of the Great Forest of Jura!

Rimuru and his companions visit the Dwarven Kingdom, the Armed Nation of Dwargon, in search of some artisans to help the Goblins learn to supply their own food, shelter, and clothing. However, a skirmish just outside the city gate lands Rimuru and Gobta in a prison cell. Then there's a report of an Armorsaurus in the nearby mines!

Thanks to Rimuru's skill, Kaijin was able to finish all the longswords and deliver them to the king, so the two of them celebrate by heading to a bar staffed by lots of elf girls. One of them reads Rimuru's fortune for fun, and sees an image in her crystal ball of someone she believes Rimuru is destined to be with. As everyone wonders who this person could be, Vesta shows up and starts to hassle Rimuru...

One day, in the midst of the improvements on the Goblin Village with the help of Kaijin and the dwarves, Rimuru meets a trio of adventurers from the Guild who've been temporarily joined by a masked woman named Shizu. Shizu turns out to be the person Rimuru is destined to be with, as his fortune said. Shizu also came to this world from Japan, but unlike him, she was summoned here many years ago. So Rimuru uses his Thought Communication skill to show Shizu what Japan looks like today.

The Demon Lord Leon Cromwell summoned Shizu out of Tokyo as it burned during in the air raids, then forced the high-ranked spirit Ifrit to possess her. After taking over Shizu's body, Ifrit begins to rampage.

When Shizu was still with Demon Lord Leon, it was a Hero who rescued her. That Hero was Shizu's inspiration to help as many people as she could for many years. She even worked as a teacher for children who'd come from other worlds. And now, as her time comes to an end, Shizu asks Rimuru for one last favor...

Rimuru and the Goblins' village is developing nicely. The Dwarves are building all kinds of houses and furniture, and the local Goblin Lords have appointed Rigurd as the Goblin King. As Rimuru watches everything come together, he decides to return to the cave and test the skills he received from Shizu. While there, he receives a request for help from Ranga through Thought Communication, and he rushes back to find his friends facing six Ogres. One of them orders Rimuru to "reveal his true identity." What is going on in the Great Forest of Jura?

Six Ogres are all that remain of their clan after an attack by an Orc army. They say that the Orcs were traveling with a mysterious majin who wore plate mail and a clown mask. Rimuru proposes that the Ogres join his ranks, and they accept on the condition that they will get to take down the one leading the Orcs, so Rimuru gives all six of them names. Meanwhile, the Orcs begin to invade the marshlands surrounding Lake Siss that are inhabited by the Lizardmen. So the Lizardman chieftan gives his son, Gabiru, an order...

Rimuru's village has gained Benimaru and the other five Ogres as its newest allies. Soon after, the Lizardman Gabiru visits the village, having heard rumors about it. Gabiru has been visiting Goblin villages throughout the Great Forest of Jura to enlist their aid in fighting off the Orc army. When he faces Ranga with an attitude of provocation, Ranga tells him that if he can defeat Gobta, they'll hear what he has to say...

The Orc army, led by the Orc Lord, continues its conquest throughout the Great Forest of Jura. The crisis has spurred Treyni of the Dryads, the caretakers of the forest, to take action. She has had her eye on Rimuru after noticing his rise to prominence in the forest, and she wants Rimuru to defeat the Orc Lord.

Rimuru and his Goblin riders set out for the marshlands to finalize their alliance with the Lizardmen. On the way, they save a Lizardman who'd been attacked by the Orcs. The victim turns out to be Gabiru's younger sister, who reveals that Gabiru led an insurrection and left to fight the Orc Lord without waiting for the alliance. She also pleads with Rimuru to save Gabiru and the rest of her clan. Meanwhile, Gabiru faces the massive Orc army and is shocked when he witnesses the power of their unique skill, Starved.

The majin Gelmud makes his appearance at last. His true goal was to evolve the Orc Lord into the Orc Disaster, a Demon Lord, and have him reign over the Forest of Jura. Upon learning this, the Orc Lord takes action...

Post-war arrangements following the battle with the Orcs have begun. At the meeting, Rimuru reveals that he made a promise with the Orc Disaster, Geld, to take all of the Orcs' sins upon himself. When the Ogres and Lizardmen hear this...

The Jura Tempest Federation, with Rimuru as its leader, has formed an alliance with the Armed Nation of Dwargon. Just as Rimuru thinks there are only peaceful days ahead, he senses an enormous mass of magical power heading straight for his location at an incredible speed. When the smoke from its collision with the ground clears, standing in its place is a humanoid figure. She is the Demon Mord Milim, the one and only Dragonoid and the one bearing the nickname "Destroyer." Ranga, Benimaru, and the others who face her are quickly overwhelmed by her power.

The Demon Lord Carrion has sent one of his Three Beastketeers, Phobio, on a raid of Rimuru's city. However, Phobio is quickly defeated when Milim meets his attack with her own. Rimuru and his subordinates then ask Phobio why he has come to their town.

Phobio can't restrain his anger toward Milim. He finds himself faced with Footman and Tear, two masked members of the Moderate Harlequin Alliance, who suggest that he become a Demon Lord to take revenge on Milim. They tell him that he can accomplish this using the power of Charybdis. Meanwhile, the Jura Tempest Federation sends Youm out on a journey to make the world believe he was the champion who defeated the Orc Lord.

Rimuru and his forces attempt to destroy Charybdis with a full on attack, but fail, so Rimuru decides to take on Charybdis alone and learns the shocking truth!

The threat of Charybdis has gone. That night, Rimuru has a dream in which he sees Shizu teaching children at her school in the Kingdom of Ingrassia—a dream showing Shizu's lingering regret. To see her wishes through, Rimuru leaves the Jura Tempest Federation and heads for the capital of the Kingdom of Ingrassia. His first goal is to meet with the Grandmaster of the Guild, Yuuki Kagurazaka, who happens to be a Summon and a former student of Shizu's.

Rimuru becomes the new teacher for Shizu's students. However, having been summoned into this world against their will and facing shortened lifespans as a result, the children's feelings are complicated, and they're reluctant to accept Rimuru. So Rimuru proposes a series of mock battles with each of them to ascertain their abilities and allow them to let off steam.

Summoning superior might save the children, so Rimiru enters the Dwelling of Spirits. The Queen of Spirits is amused by Rimuru and decides to put him through a test.

In the heart of the labyrinth, Shizu's students pray to summon superior spirits. As Rimuru watches over, an overwhelming presence appears. Will Rimuru finally be able to fulfill his promise to Shizu?

Long ago, Shizu is called to the kingdom of Filtwood to stop a revived demon who poses a grave threat to the world. But as the adventurers are briefed, a mysterious being named Black appears who challenges Shizu to a fight.
