## Empowerment Arc

Satoru Mikami woke up finding that he got reincarnated as a Slime, which took him some getting used to. As slimes don't sleep, can't see, and only have the sense of touch, he ate nearby grass to pass the time. After 90 days of boredom, the skill Great Sage finally finishes integrating the slime's desire to have a "conversation partner" which caused him to learn about the world with the new question and answers feature of the skill. It turned out that the grass he ate out of boredom is actually Hipokute Herbs, a material for high-grade health restorative Potions.

During his time inside the cave, he met another lifeform, the *Storm Dragon* Veldora. The Storm Dragon proved himself friendly and taught him how to perceive the surroundings via Magicules through the use of the *Extra Skill* Magic Sense, which soon grants him the ability to see. Veldora also reminisces about the peerless beauty of a Chosen Hero that defeated him 300 years ago... the two of them become friends and then named each other as equals. Veldora becomes **Veldora Tempest**, and the slime was named **Rimuru Tempest**. To break the unbreakable Infinity Prison, they agree to stake Veldora's freedom on Rimuru's *Unique Skill*, and Veldora got stored in Predator's inescapable storage space, stuck in time, and undergoing Great Sage's analysis.

With a new goal in mind and friend in heart, Rimuru eventually gets out of the cave with some unintentional help from three adventurers who were sent to investigate Veldora's disappearance. It was only after using the Great Sage's mapping function that he succeeded though. During the 30 days after meeting Veldora, Rimuru ate more grass and rocks, namely Hipokute Herbs and Magic Ore, as well as other monsters that he fought and killed, and develops some personal fighting skills to defend himself, such as the *Common Skill* Water Blade.

Whilst exploring the forest outside the cave, Rimuru plays around with a sound-emitting skill acquired from predating a cave bat and achieves speech. He met a group of goblins and got invited to their village. It turns out the Goblins are being threatened by a pack of Direwolves. After hearing the situation from the village chief and being promised eternal loyalty, the good-natured Rimuru helps them, defeats the wolf pack's leader, and acquires the rest of the pack as subordinates. He tells the goblins and wolves to get along with each other, and thus the new village is born under his rule.

In this world most monsters are nameless, with only high-level Majin being able to bestow names on others. When Rimuru realizes that there is no convenient way to get their attention beyond addressing them as "you," he names them all. Among them, the village chief is named Rigurd, the chief's son is named Rigur, the new wolf leader is named Ranga, and a natural bloke goblin is named Gobta, who later becomes a remarkable figure among Rimuru's top retainers. All the named monsters evolve, becoming stronger, but they no longer fit their clothes or their door frames, so Rimuru, along with Gobta, Rigur, Ranga, and a group of Hobgoblins and Tempest Wolves, go to the ***Dwarven Kingdom* Dwargon** to acquire clothes and a skilled house builder.

Rimuru, after some misunderstandings, helps out a masterful blacksmith, Kaijin to fill his quota on swords per the King's request. It turns out the Magic Ore that Rimuru ate in the '**Sealed Cave** is a high-class smithing material. In return for helping him out, Kaijin promises to procure Rimuru a good blacksmith, and Rimuru offers to help Kaijin's friends, Garm, Dord, and Myrd, who are very skilled at their crafts but bad at business. They soon pay a visit to a bar where they meet some female elves who become attached to the slime. However, a certain Minister *Minister* Vesta ruins this due to him resenting Rimuru, and Kaijin, after delivering his quota, is exiled from the country along with Rimuru and the three dwarven brothers. The four dwarves, Rimuru, and the company then return to the village.

Upon returning, some other goblins' villages join Rimuru's new village after hearing of his grandeur. Rimuru names and evolves them afterward. The Dwarves and Hobgoblins immediately start working on building housing. As they are constructing the new town, Rimuru meets four adventurers (three of them are the same ones whom he saw eariler when leaving the cave) who are surveying the land in front of Veldora's cave on the **Free Guild** Branch in the small country **Blumund**'s behalf. The adventurers are a happy bunch. Rimuru discovers that one of them was an otherworlder, originally from Japan, going by the name of Shizu.

After spending some time together and learning about each other, Shizu loses control of the Elemental Ifrit. Rimuru managed to beat and separate it from Shizu, trapping it inside his stomach along with Veldora. Unfortunately, Shizu is now dying of old age without her elemental spirit. Her full name is Shizue Izawa, also known as the *Conqueror of Flames*. She explained her situation to Rimuru; She was summoned by *Demon Lord* Leon Cromwell and now she asks Rimuru to *"remind the Demon Lord of her existence"* and help her students, asking him to absorb her corpse because she does not want to be buried in this world.

After absorbing Shizue, Rimuru can now mimic a human form - a beautifully androgynous human that looks similar to Shizue with the head of a woman and the body of a man. Other key abilities acquired from absorbing Shizu and Ifrit include Body Double, Flame Manipulation, and a new Unique skill Degenerate. Rimuru, later on, sends off the trio of adventurers with a parting gift, with them promising to send the news back to the guild that his village is friendly towards humans. In turn, they say goodbye to their deceased friend as Rimuru takes his human form again. Rimuru now has a new goal in mind besides freeing Veldora, saving Shizu's former students, and meeting *Demon Lord* Leon Cromwell.

## Forest Disturbance Arc

Getting used to his new abilities, Rimuru relied on Great Sage to adjust (seperate or combine) them using his new *Unique Skill* Degenerate. Meanwhile, he received an emergency message through Thought Communication from Ranga. Rimuru ran to Ranga's current location and found him, Rigur, and Gobta in a middle of fight, with the rest of the Goblin Riders knocked out via magic. The culprits turned out to be 6 ogres who accuse Rimuru of being an evil majin who conspired with the orcs to attack the ogres. After a battle and with the *Ogre Princess*' persuasion, Rimuru finally manages to resolve the misunderstanding. Inviting the Ogres to a feast since there had been no causalities and hence no bad blood between them.

They started the feast where they discussed the situation alongside Rigurd, Regurd, Rugurd, Rogurd, Ririna, and Kaijin. The ogres (numbering 300) were attacked and defeated by around 10,000 Orcs. Kaijin speculated that they were being controlled by a demon lord behind the scenes due to the absurdly high number. Rimuru heard the discussion and discovered that the remaining ogres were planning to simply charge into their deaths. He asked if they were willing to become his subordinates (temporarily even, if they so wished). After a while of thinking, the "young master" of the ogres agreed to a temporary contract and they were thus named Benimaru, Shuna, Shion, Hakurou, Souei, and Kurobe, making Rimuru enter his low-activity/sleep-mode state.

After he awakened, he was surprised to see the B to A- Rank ogres all evolve into Rank A Kijin. Later on, they were all assigned with jobs: Kurobe as a blacksmith and craftsman, Shuna in weaving and cooking, Shion as a secretary, Souei in espionage, Hakurou as an instructor and Benimaru as the army commander.

Rimuru's village was visited by lizardmen envoy led by Gabiru who proposed to Rimuru's group that they should be working under them against the incoming orc's invasion. It turned into a duel between Gabiru and Gobta, which Gobta won, causing the Lizardmen to run away. While pondering what to do about the incoming invasion, Rimuru was visited by a dryad named Treyni who asked for Rimuru's help in exterminating the *Orc Lord*. Shion accepts on Rimuru's behalf and they began their war preparation against the orcs.

Rimuru sent Souei to negotiate with the lizardmen's chieftain, while the rest were ordered to make weapons and armors for the upcoming battle. After a week of preparations, Rimuru sets off together with the Kijin and the Goblin Riders to start a counter-attack. They met with a lizardman fighting an *Orc General* with some orcs and saved her life. She explained that she is the chieftain's daughter and Gabiru's brother and that Gabiru had overthrown the chieftain and is battling against the orcs at the moment. Rimuru promised to save the lizardmen and sets off to finally deal with the orcs.

The Kijin showed off their newly acquired power and Ranga managed to evolve mid-battle into a *Tempest Star Wolf*. Before Rimuru can battle the *Orc Lord*, Gelmud showed up, trying to kill Gabiru so as he can become food for the Orc Lord, but after Rimuru prevents that, the *Orc Lord* Geld kills and devoured Gelmud causing him to evolve into a demon lord seed and became an *Orc Disaster*.

Seeing as the Kijin's attack isn't working against the Orc Disaster, Rimuru chose to battle it by himself. After a fierce battle of corrosion and devouring each other, Rimuru managed to beat down the orc disaster and convince him that Rimuru himself will shoulder the sins of the orcs, and let Geld rest in peace.

After the battle was over, Treyni announced a forest meeting to discuss the aftermath of the war and invite every participating races to bring over their representatives. During the meeting, Rimuru managed to convince the participating races to not only forgive the orcs but for them to work together from here on out. Everyone agreed with the idea and Rimuru became the chancellor of the newly founded ***Jura Forest Alliance***.

## Demon Lord Attack Arc

With the orcs and other races now working together, Rimuru's town became even bigger and started to gain the attention of the surrounding eyes, monsters, and humans alike. It soon became the Jura Tempest Federation.

Gazel Dwargo, the *Dwarven King*, is surprised at the reports of the monster town and wishes to ascertain their nature, while four *Demon Lords* - Milim, Frey, Carrion, and Clayman - plan to send their subordinates to them to scout them out. On the other hand, a noble from the **Falmuth *Kingdom*** sends out a scouting unit consisting mostly of prison inmates to investigate the remaining orc army inside **Jura Forest**. The *Frontier Expedition Force* led by Youm was tasked with that job. After a brief duel with Dwargo, he sees that Rimuru isn't evil and allies with him. Sometime later, when Milim visits, Rimuru's subordinates consider her a threat and attack her, but she proves to be stronger than them. Rimuru is able to tame and befriend her using honey, which she likes, turning her into an ally. Following the awakening of Charybdis, Milim helps Rimuru's forces defeat him. Rimuru later leaves the town to the Freedom Academy, a school where Shizue originally worked at, where he meets the grandmaster Yuuki Kagurazaka and Shizue's students, intending to fulfill his promise to help the students by becoming their new teacher. The students aren't very respectful of him, so he decides to show them the difference in their skills in a series of duels. They lose and accept him as their sensei, but they soon begin to bond after learning that Shizu tasked him to help them. Rimuru visits Treyni, believing the children will survive if inhabited by superior spirits since Shizu was summoned as a child, but lived to adulthood, possibly because of Ifrit. Treyni directs him to the Dwelling of Spirits, but with the Queen of Spirits the dryads once served dead, they have lost their link to it and no longer know the entrance. While on a picnic with the students, he challenges them to another fight and will reward them with a new manga if they win, but they end up losing again. They see a Sky Dragon heading to the capital and, after entrusting them with Shizu's mask, Rimuru interferes and eats it with Gluttony. Mjolmire, a merchant whose Rimuru's appearance is saved, invites them to dinner. Mjolmire knows who Rimuru is and Rimuru invites him to come to Tempest to help them sell their wares. He agrees. Mjolmire's assistant asks the Queen of Spirits to protect the children after dinner. She tells a curious Rimuru she came from a village near the Dwelling of Spirits. He, Ranga, and the children head to its location. Rimuru, Ranga, and the students enter the Dwelling of Spirits and a spirit in the opening labyrinth battles them with a giant metal golem to test them, though Rimuru quickly incinerated it. The labyrinth spirit introduces herself as Ramiris, one of ten Demon Lords, though she's so small no one believes her. She explains that Leon Cromwell, who summoned Shizu, used to be a Hero before he fell from grace and become a Demon Lord. Likewise, she used to be the Queen of Spirits before dying and returning as a Demon Lord. In exchange for creating a new golem for her, Ramiris agrees to aid Rimuru in summoning superior spirits. He also reveals his true appearance to the students. A plethora of inferior spirits answer the prayers of Gale, Alice, and Ryota so Rimuru devours them and turns them into three new superior spirits, which successfully inhabit the three. Kenya summons and is inhabited by a superior spirit of light. An unknown spirit-like being appears as Veldora reacts to its presence. Despite Ramiris's attempt to stop it, as she feels it is dangerous, it still possesses Chloe. Regardless, the dangerous energy in the five children has calmed, so they will not die in a few years. Rimuru makes a new golem for Ramiris and they return to Ingrassia. Yuuki finds it unlikely the nations that abandoned the children will try to take them back so they should be able to live normal lives. Rimuru doesn't tell Yuuki how he saved them. Rimuru thinks about the past two years and declares all their problems have been solved. He gives Chloe Shizu's magicule-suppressing mask but isn't certain why, simply feeling it was for the best. Unknown to Rimuru, a shady woman is spying on him.

### OAD

During Rimuru's time at Freedom Academy, they help Class S prepare for their upcoming exam and provides them with weapons and a special carriage called the Camping Car. They soon get into a rivalry with Jeff Segal, the teacher of Class A. When the exam comes, Rimuru is assigned to go with Class A. After defeating some monsters, they gives each student some pointers on improvements. Once they arrived at the Town of Guratol, they helped Count Guratol cure his sick wife, revealed to be Jeff's sister and explaining why Jeff was so determined to win. This causes Jeff to start respect Rimuru more.

## Visions of Coleus Arc

Rimuru is asked by Yuuki to investigate a war going on in the Kingdom of Coleus. He learns that the kingdom's princess Zenobia has fallen ill and is able to help cure her. During his investigations, he soon discovers that it was all a game controlled by the Arch Demon Gustav, who seeks to implant his "God" into Zenobia's body, having made her ill to manipulate her brothers into fighting each other. To keep Rimuru from interfering, he has him arrested after falsely claiming that his cure did more harm than good, but he leaves a Body Double in his cell, takes the form of his old human self, and uses his old name as an alias to save Zenobia. During a confrontation with Gustav, the Demon Lord Luminous Valentine joins in on the fight to stop Gustav's scheme, but he manages to succeed in his goal; his "god" is revealed to be the Primordial Demon Violet, who has a rivalry with Valentine. However, Violet isn't satisfied with her new vessel because it was not a proper one yet and had Gustav killed for his failure before leaving Zenobia's body. After the confrontation, Rimuru returns to his cell and takes his Body Double's place just before he is released from his cell by Zenobia's brothers, who learn of his true identity. Rimuru then returns to Tempest and informs Yuuki of his success.

## Human-Monster Interaction Arc

After Rimuru finishes his time as teacher, he has another teacher take over for him as he returns to Tempest. By this time, he starts negotiations to establish diplomatic relations with the Beast Kingdom Eurazania, led by Carrion, by meeting with the Beastketeers, which ends in success. The mysterious woman from before reveals herself as Hinata Sakaguchi and challenges him, believing that he killed her teacher Shizue and wants to avenge her. She proves to be too powerful for him due to an anti-magic force field in the area, but he creates a Body Double to trick her into thinking that she won. Once she left, he came out of hiding. He then returns to Tempest to find the kingdom under a much larger anti-magic force field (which he manages to slip through) and severely damaged from an attack from the Falmuth army, who deem the monsters living there a threat, as well as learning that the magician Mjurran is an enslaved minion of Clayman, who is the mastermind behind the attack.

## Demon Lord Awakening Arc

Rimuru was angered because the Kingdom of Falmuth killed many of the citizens of Tempest, including Shion and Gobzo. He decides to absorb them, but Eren intervenes telling Rimuru that he can revive them by massacring 10,000 humans, thereby becoming a Demon Lord. Great Sage deduced that the chance of success was 3.14%. Rimuru then makes his resolve and sets his plan in motion. Before doing so, he frees Mjurran from Clayman's control and tricks him to believing that she died. After creating another force field to counter Falmuth's, Rimuru starts his attack having his subordinates destroy the crystals powering the anti-magic force field, slaying many of the knights in the process. They are successful and after the force field is gone. Rimuru engages the majority of the Falmuth army using a spell called Megiddo to mercilessly massacre the soliders. After about 5,000 or so have been slaughtered, he acquired a skill called Merciless, which harvests the souls of those who have lost the will to fight. He then immediately uses the skill to kill the rest of the Falmuth army. The only survivors were the king of Falmuth, archbishop Rayhiem, and the court mage Razen. All of this happens before confronting the two because he killed Razen's body. After which, Rimuru begins his harvest festival, an event where one becomes a true demon lord and puts him into sleep. Rimuru begins to feel extremely tired, and there are still dangers around, with Razen surviving his skill Merciless. Because of this, he summons Ranga to take him back to town. He also summons 2 Greater Daemons and an Arch Daemon that he names Diablo, who ally with him and is ordered to capture Razen. Immediately after, he loses consciousness, and begins his harvest festival. During which, his unique skills then evolve into Ultimate Skills. His unique skill Great Sage evolves into the ultimate skill Lord of Wisdom, Raphael by sacrificing Degenerate, and his unique skill Gluttony evolves into Lord of Gluttony, Beelzebuth by sacrificing Merciless. After which, he wakes up with Raphael taking the reins of his body, who then revives Shion and the rest of the fallen citizens. He then falls back into sleep and wakes up three days later.

## The Octagram Soars Brightly Arc

After giving Veldora a new body, learning that Yuuki is the true mastermind behind the recent events, and helping to defend Eurazania from Clayman's forces, Rimuru soon attends the Walpurgis Banquet, where Clayman presents his false story of how Carrion encouraged Rimuru to become a Demon Lord and set up the Harvest Festival for him by influencing Falmouth to attack Tempest; Milim (who had been brainwashed by Clayman) and Frey only helped punish Carrion for creating a Demon Lord without majority consent of the existing Demon Lords, and Clayman calls for them to destroy Rimuru in response to this. Rimuru calls him out on all the lies, revealing that Mjurran is still alive as a witness and Tempest's forces have collected more than enough evidence tying Clayman into the manipulation of Falmouth, which Clayman dismisses. Head of the Demon Lord council, Guy Crimson, tells them to fight it out; he wants the matter resolved simply and quickly. Clayman has Milim fight with his subordinates, leaving Rimuru's side unbalanced. Beretta joins the fight on Ramiris' behalf. Veldora soon joins in on the fight. Beretta takes out the puppet Clayman summoned, while Rimuru frees the fox demon under Clayman's control and puts it under Ranga's care. Clayman, in the meantime, finally snaps and loses his composure, transforming into his Crazed Clown form. His weakness and plots are exposed with his defeat by Shion and Carrion reveals himself to be alive and as one of Frey's attendants. Milim reveals that she was never mind controlled and was faking it all along (the neckless used to mind control her didn't work at all) while Frey reveals that she was never on Clayman's side at all, much to his anger. In utter despair at his own weakness, Clayman then powers himself up and plans to kill Rimuru to keep his title. However, Rimuru simply pummels and eats Clayman instead; learning the Moderate Harlequin Alliance works for former Demon Lord Kazeream, whose body Leon killed to take his spot and was also the one who gave Clayman the failed mind control neckless. Thanks to Veldora and Milim's blunder, Rimuru learns that Roy Valentin is revealed to be a stand-in for Luminous Valentine (who is disguised as a maid), whom he was suspicions about earlier. Carrion and Frey give up their seats as Demon Lords upon seeing they are too weak; while still ruling their lands, they now work for Milim. As the group is down to eight members, Veldora suggests Rimuru pick their new name. Rimuru sees stars above the meeting and decides to call them the Eight Star Demons Lords - Octagram.

## Scarlet Bond Arc

Rimuru soon meets Hiiro, a friend of his subordinates, who came from the Kingdom of Raja to inform them of Queen Towa's illness. He agrees to help and heads to Raja with his subordinates. At the lake, Rimuru reveals to Towa that the toxins that are indirectly causing her illness are not from mines. He then splits the lake into two to reveal a hidden structure with an old magic circle that produces the toxin and destroys it. These events have angered Lacua, the merchant behind the poisoning, and schemes another chaos to earn praise from Violet, revealed to be the mastermind behind the scheme, who is again attempting to gain another body. Sometime later, the lake is poisoned again, so Towa uses her tiara to purify it, resulting in her health deteriorating. Her worsening condition causes a neighboring country to take advantage of it to attack Raja and seize the large gold that the kingdom mined before. Having learned of the news about the kingdom, Rimuru mobilizes his allies, while Diablo heads out to meet with Violet, who has created the tiara and the magic circle at the lake. After Hiiro is tricked by Lacua to ingest a Curse Orb, being told that it is for transferring Towa's soul to his healthy body, he is fed by him with memories of his village being destroyed to fuel his transformation. Rimuru chases after Lacua, while Benimaru fights Hiiro and Shuna protects Towa. Meanwhile, Diablo confronts Violet, who reveals that she has given the tiara to the previous queen of Raja as a game in which if the possessor is fully inflicted by the Curse Poison then she can take over the body and be physically reborn. After failing to defeat him, Violet agrees to Diablo's terms of leaving Raja alone while also voiding the contract with Towa after learning that Lacua tampered with her game against her wishes instead of observing only; this displeases her and she cuts ties with Lucua for his disobedience and ends her game. Rimuru then defeats Lacua, who then blows himself up to destroy everything around him, but the explosion is contained by Rimuru. Hiiro manages to remove the orb from his body and destroy it. Raja's doctor is revealed to be in allegiance with Lacua, but he is killed by Ranga. Towa uses the full power of the tiara to revive him, causing her body to be covered by the Curse Poison and vanish. However, Violet returns Towa to life after voiding the game as an apology for her subordinate's actions. During the celebration, Rimuru offers the kingdom's ministers help in rebuilding Raja in exchange for Tempest buying their iron ore. Rimuru returns to Tempest and finds it partially destroyed after Veldora and Milim played together, and he punishes them before collapsing from exhaustion.
