Rimuru Tempest/Relationships

Jura Tempest Federation

 * Great Sage / Raphael
 * Rimuru views Raphael as his reliable partner while Raphael views Rimuru as its "master" it tries to be useful for. Raphael as Great Sage first came to be when Rimuru was first reincarnated as a slime and desperately wanted a conversation partner. This desire caused the Unique Skill Great Sage to undergo a mutation for 90 days that implemented the Voice of the World to become an interactive Questions and Answers input-output device. It seemingly also started to work on Rimuru's subconscious desires and strengthened Veldora and Ifrit in Rimuru's stomach, obfuscated Rimuru's deeper thoughts from Gazel Dwargo's mind reading and improved Rimuru's internal magicule processing during naming to allow him to go on his mass-naming-sprees without any permanent losses in power.

While initially Rimuru relied on it for many things, Rimuru started to be able to handle increasingly more things on his own, leaving Great Sage with less workload, making it deem itself like it's being less useful. Being unable to analyze Milim's Drago Buster in the fight against Charybdis and the Spiritual Body of Chronoa at the Dwelling of Spirits, it found itself wanting to make up for its failures from those times, culminating in Rimuru's Harvest Festival where it made the decision to sacrifice and integrate the Unique Skill Degenerate into itself in order to succeed at evolving itself without asking Rimuru for permission, which caused it to start developing self-awareness and its own will.

As Raphael, it tries to guide Rimuru on the way of improving himself and becoming stronger as long as Rimuru has even the slightest bit of desire for it, even resorting to tricking Rimuru himself to achieve that but Raphael never refuses any orders that Rimuru issues seriously.


 * Ranga
 * Ranga was the son of the previous Direwolf Boss who Rimuru killed in defending the Goblin Village. Once Rimuru transformed into a direwolf and exerted his aura, Ranga and the rest of his pack yielded to Rimuru in a subservient manner which surprised Rimuru since he killed their leader. Though Ranga admitted he pondered over if he should hate Rimuru for this, he ultimately decided it was his fathers own fault and serves Rimuru faithfully. He was among the first group of monsters that got named by Rimuru. Due to living in Rimuru's shadow most of the time, Ranga has constantly absorbed his aura. He had previously experienced a transformation into a Tempest Star Wolf due to his constant exposures and absorption of the aura. Rimuru sometimes notes that Ranga's loyal dog-like behavior can ruin his image of a cool wolf.

Ramiris' Labyrinth

 * Veldora
 * Rimuru and Veldora became fast friends after meeting each other, even considering each other sworn brothers. Veldora has such a great amount of trust in Rimuru that he allowed Rimuru to devour him the first time to be freed from his Infinity Prison. After Veldora finally receives a body, he spends his time lazing around and reading manga but is willing to take the blame for Rimuru for the massacre of the Falmuth's soldiers. Later on the story, Veldora becomes the "Final Boss" of the The Dungeon and also a playmate of Rimuru alongside Milim, Ramiris, and later also Gaia. He also sometimes gets punished by Rimuru by him spoiling his manga plots and taking away his snacks.


 * Charys
 * To Be Added.


 * Ramiris
 * At first, Ramiris was angry and also scared of Rimuru when he destroyed her Elemental Colossus but, she warmed up to him quickly. Rimuru, before leaving the Labyrinth, summoned a Greater Daemon, gave it a Magisteel puppet body and named them Beretta. Doing this resulted the Arch Doll to become more powerful and intelligent as a guardian better than Ramiris' former Elemental Colossus.

When Ramiris visited Tempest to warn Rimuru about Clayman's attempt to frame and attack him, she got acquainted with Veldora, who taught her about the existence of manga, which caused Ramiris to start calling Veldora her "instructor". This gave her another reason to insist on staying in Rimuru City, which Rimuru was reluctant about, but had more pressing matters to attend to and post-poned the matter until a later time. Ramiris helped Rimuru to participate in Walpurgis himself in order to make his case as a new Demon Lord and to confront Clayman.

Soon after the Clayman matter was settled, Ramiris tried to move into Rimuru City again, with Rimuru favoring the position of refusing her request, but Beretta, who wanted to have both his current master Ramiris and his new body's creator Rimuru close to him, tried to speak up in favor of Ramiris to achieve this goal. Rimuru ended up reluctantly agreeing, quickly trying to make the best use of the situation, planning to move her labyrinth to Rimuru City, and preparing it to potentially making it an attraction to adventurers. With Ramiris providing the Labyrinth itself as well as the "resurrection bracelets" to prevent unnecessary deaths, Rimuru providing the venue for the entrance and the advertisement, along with Veldora's help in supplying the magicules to run the labyrinth and create monsters, and Milim providing some living Dragon Kings as late-floor "bosses," the four of them quickly became playmates who later ended up turning the labyrinth into a game where the four of them possess avatars they created to play around being secret field bosses against the adventurers who enter it. Ramiris also takes over Tempest's post as head of the researchers.

Humans

 * Gard Mjöllmile
 * Mjöllmile first heard of Rimuru when he was referred to Tempest by Fuze to bring Tempest's High Potions into the market. He only arrived in Tempest when Rimuru was already on his trip, so he could only learn about Rimuru through words and drawings of varying accuracy. Upon Mjöllmile coming to the Kingdom of Ingrassia's capital Lura to sell the potions, he got attacked by a wandering Sky Dragon at the city's entrance and got rescued by Rimuru in his adult-form disguise, who Mjöllmile mistook for a Goddess at first glance. Rimuru and Mjöllmile soon after hit it off, with their shared merchant nature causing them to quickly become business partners and friends.


 * Masayuki
 * Masayuki in his series of misunderstandings caused by his Unique Skill Chosen One that makes all his actions look heroic, eventually made his way into Tempest. The misunderstandings caused him to have to challenge Rimuru since he was afraid of his followers turning on him if he did not go along with the flow. Eventually Rimuru managed to talk to him alone upon which the reveal that both are Otherworlders from the same Japan made Rimuru very happy as the only other Otherworlder he could have a decent talk with until that point was Yuuki. Masayuki ends up being hired by Rimuru, working on Tempest's public relations to soften the relationship between Monsters and Humans.

Goblins

 * Rigurd
 * The village chief of the first goblin village that Rimuru encountered. He and the entire village swore their loyalty to Rimuru after Rimuru promised them that he'd protect their village from the invading Direwolves, becoming his first subordinates. As the first individual to ever be fully named by Rimuru, he, as the Goblin King, is entrusted by Rimuru to govern the Jura Tempest Federation as its Prime Minister.


 * Rigur
 * The second son of Rigurd who, like his father, is also extremely loyal to Rimuru as the second individual to be named by him. At first leading the Goblin Riders, Rigur later handed his position to Gobta. Rimuru trusts him enough to be sent as a diplomat to represent Rimuru in Eurazania.


 * Ririna
 * As one of the Goblin Lords, Ririna is trusted by Rimuru to handle the food supply of Tempest.


 * Gobta
 * Gobta is the third individual to be fully named by Rimuru. Rimuru regards Gobta as a genius, though quite an idiot at the same time, as well as sometimes calling him prodigy, and the subordinate that Rimuru is the most casual with.

Dwarves

 * Kaijin
 * The Dwarf swears loyalty to Rimuru after Rimuru helped him out of his predicament of meeting the quota for providing swords to the Armed Nation of Dwargon and being exiled from there. He works together with Kurobe on the production of weapons.


 * Garm, Dord and Myrd
 * Three brothers that worked with Kaijin and sided with Rimuru during his court hearing when he went to Dwargon. When Rimuru first arrived in Dwargon, it was his healing potion that saved their lives when they were attacked by an Armorsaurus in the mines. They came to live in Tempest after being exiled and contributed greatly to the growth and technological development of the Federation.


 * Vesta
 * Vesta was at first antagonistic towards Rimuru due to being an associate of Kaijin who Vesta was jealous of. After being exposed as a liar and fraud, he is banished from the Dwarven Kingdom's royal court, but is later delivered to Tempest by Gazel Dwargo in the hopes that his genius would not go to waste. Kaijin vouches for his abilities and Rimuru takes him in as a researcher. Vesta is successful in developing a 99% effective healing potion with Rimuru and Gabiru's assistance and has contributed to many of the magical and technological advancements of Tempest, while also being a proxy of contact to Dwargon.

Kijin / Oni

 * Benimaru
 * Benimaru is one of the most loyal servants of Rimuru, despite initially being the heir of the Village Chief position of the Ogre Village. Rimuru entrusts him with the position of Commander-In-Chief of the Jura Tempest Federation as one of Rimuru's top executives with the title of "Samurai General." Because Benimaru once almost let Rimuru become one of the victims of Shion's cooking, Rimuru forced him to be the official taste-tester of her cooking training, much to Benimaru's dismay.


 * Souei
 * Souei is Rimuru's loyal "Spy Chief" who leads Tempest's Intelligence Bureau and is the boss of the elite "Azure Shadow Squad," that's led by Souka. Despite Rimuru being somewhat jealous about Souei's pretty boy demeanor, Rimuru always humors his Ninja-like behavior by giving firm and direct orders to Souei, unlike his usually more casual tone.


 * Hakurou
 * As the "Instructor," Hakurou is Rimuru's and the entire Tempest Military's teacher in the way of the sword. He also teaches Arts, even though those are usually the specialty of humans', as monsters are usually more reliant on raw power and Intrinsic Skills. The Formhide Art that Hakurou taught Rimuru ended up saving his life when Hinata ambushed him.


 * Shion
 * Shion is the "Secretary" and bodyguard of Rimuru. They first met when she and her fellow ogres mistook Rimuru to be one of the masked majin responsible for the destruction of their home due to him being in human form and wearing Shizu's mask at the time. After Rimuru subdued them easily and showcased his overwhelming power, the ogres realized that he was not one of the masked majin and sought his forgiveness. Originally Shion and the ogres formed a temporary contract with Rimuru being his mercenaries in exchange for shelter in Tempest until the "Orc Invasion" was dealt with. After Rimuru named all six of them and later defeated the Orc Disaster, Shion and the ogres decided to become Rimuru's devoted servants.

Since then, she has become one of Rimuru's greatest fans and constantly competes with Shuna and others to be his number one servant. Rimuru genuinely cares for her and appreciates her, however her awful cooking and clumsy behavior makes him feel exasperated at times.

When Rimuru found out that Shion died from the invasion by the Kingdom of Falmuth's vanguard, he became depressed, heartbroken, aggravated and angry that his 'naive rules' got her and one hundred other Tempest citizens, among which were many children, killed by Falmuth and the Otherworld Trio. Although Rimuru notes that unlike the case of Shizu, Rimuru was not crying, which Rimuru attributed to truly having become a monster. When he heard that becoming a Demon Lord could potentially revive them, it became his sole purpose for becoming one and slaughtering the Falmuth Army. Since her revival, she obtained the Unique Skill Cook which makes her food taste good, although her bad prep work and the resulting weird texture of the food would still incur Rimuru's annoyance. She also competes with Shuna for who gets to hold Rimuru, even getting stretched apart in the clash much to his annoyance.


 * Shuna
 * One of Rimuru's most loyal servants. In their first encounter, when she and her kind thought that he was their enemy, she is the first to trust and defend him after seeing his power and a glimpse of his true character. She is entrusted by Rimuru to take the role of "Shrine Maiden Princess", which oversees the Server Division, the Fashion Research Division, and the Culinary Research Division, while occasionally also helping out Garm with magic equipment and taking over Shion's secretarial duties when Shion is busy with training the Yomigaeri or taking the role of Server for a meeting with an important guest that might be too difficult for her apprentice Haruna to handle.


 * Kurobe
 * Another of Rimuru's most loyal servants. Rimuru and Kurobe respect each other as Kurobe is loyal and grateful to his lord while Rimuru appreciates his blacksmith skills. The two have often chatted about making new armaments for Tempest based on Rimuru's ideas.

Orcs

 * Geld
 * Extremely loyal to Rimuru and has deep gratitude to him for adopting the orcs after Rimuru absorbed the Orc Disaster. He was astounded by Rimuru's generosity in allowing the Orcs to be a part of The Jura Forest Alliance. He took Benimaru's words to heart to spend the rest of his life in serving Rimuru as penance for his part in the Orc Lord's invasion. Geld is a hard worker but Rimuru thinks that Geld is overworking himself and constantly tells him to take more breaks.

Lizardmen / Dragonewts

 * Gabiru
 * Gabiru is one of many who serve under Rimuru. Their relationship started rocky since Gabiru looked down on Rimuru due to the fact he is a slime and even thought Gobta was the "true master" of the village. This changes when Rimuru saves Gabiru's life from Gelmud. After Gabiru's banishment from the Lizardman Tribe and deciding to serve under Rimuru, Gabiru started to slowly change. He has since swallowed his pride and learned not to look down on others, while taking things step by step and grows stronger, both in martial prowess and in character. Through he is initially clumsy, he genuinely works hard to improve himself while leading Rimuru's sky forces and helping Vesta in his research efforts, Rimuru eventually promotes Gabiru to be among his executives, which gave him his honor as a Lizardman back in his Fathers eyes, thus giving him more trust from Gabiru. He also got a new name from Rimuru despite him already having a name.

Black Numbers

 * Diablo
 * The most fanatical in his loyalty, he is truly loyal to Rimuru and will spread calamity if ordered. He views Rimuru as his "God". With his aim being Rimuru's right-hand man, Diablo strives harder than anyone in Tempest to impress and prove his loyalty to Rimuru, such as forming the Black Numbers - the strongest Corps in Tempest. Rimuru also sees Diablo as one of his most trusted retainers and gets impressed by him many times due to the outrageous display of his loyalty and shrewd mind. Rimuru doesn't find out that he and Testarossa, Carrera, and Ultima are Primordials until later.


 * Testarossa
 * She was brought alongside the two other Primordial Daemons and all their main underlings to Tempest by Diablo as she was interested in seeing the master Diablo served. Finding Rimuru to be as interesting as Diablo advertised after Carrera's full-power intimidation didn't even make Rimuru flinch, she joined Tempest and was given a physical body and the name "Testarossa". She evolved into a Daemon Lord alongside Carrera and Ultima. Testarossa serves in the Black Numbers under Diablo but is also Tempest's Military Attaché, regularly taking post as the Ambassador to the Council of the West she competes with Ultima and Carrera for his attention..


 * Carrera
 * She was brought alongside the two other Primordial Daemons and all their main underlings to Tempest by Diablo as she was interested in seeing the master Diablo served. Finding Rimuru to be as interesting as Diablo advertised after her full-power intimidation didn't even make Rimuru flinch, she joined Tempest and was given a physical body and the name Carrera. She evolved into a Daemon Lord alongside Testarossa and Ultima. Carrera serves in the Black Numbers under Diablo but also serves in Tempest's Judicative Department as the Chief Justice.


 * Ultima
 * She was brought alongside the two other Primordial Daemons and all their main underlings to Tempest by Diablo as she was interested in seeing the master Diablo served. Finding Rimuru to be as interesting as Diablo advertised after Carrera's full-power intimidation didn't even make Rimuru flinch, she joined Tempest and was given a physical body and the name Ultima. She evolved into a Daemon Lord alongside Carrera and Testarossa. Ultima serves in the Black Numbers under Diablo but also serves in Tempest's Executive Department as the Attorney General.

Giants

 * Dagura, Ryura and Debura
 * Rimuru originally met Dagura and his brothers when their father, the Giant race Demon Lord Dagruel, sent them to Tempest in order to train. They originally picked a fight with someone because they thought that they were stronger than anyone in Rimuru City. However, they soon received a one-sided beating by Shion in Rimuru City's arena despite any of their magicule amount being higher than Shion's. Since then, Dagura and his brothers became Shion's students and worked under her.

Armed Nation of Dwargon

 * Gazel Dwargo
 * Rimuru first met Gazel during a trial set up by Vesta but already knew the truth. He exiled Rimuru and Kaijin from Dwargon. They didn't meet again until several months later. After testing whether or not Rimuru has evil intentions through a sword fight and learning that Rimuru like himself is a disciple of Hakurou in the way of the Sword, Gazel starts viewing himself as Rimuru's "senior" among Hakurou's disciples and convinces Rimuru to found his own nation and become an ally of Dwargon. They appear to be on good terms and good friends with each other.


 * Dolph
 * Dolph, the Captain of the Pegasus Knights, was sent to assist Tempest in the efforts to take down Charybdis. After the battle Dolph did not believe Rimuru's explanation that it got finished of by the Demon Lord Milim Nava as that seemed too absurd of an explanation to him, instead assuming that Rimuru was just hiding the fact that Tempest had some sort of secret weapon as a trump card that Rimuru didn't want to reveal. It was only when Rimuru later came to Dwargon for the state visit and explained the situation again with Gazel himself believing Rimuru's explanation that Dolph finally got convinced that Rimuru was speaking the truth before.

Kingdom of Blumund

 * Eren
 * Eren was one of the first humans Rimuru met in this world. Rimuru is grateful to her as she is the one who told him the "Tale of the Dragon Princess" which gave Rimuru the final clue for the ritual to revive Shion and the other fallen citizens of Tempest. She was also a bridgehead for making contact with her home country, Sorcerer's Dynasty Sarion.


 * Kaval and Gido
 * Kavel and Gido were two of the first humans Rimuru met in this world. After Kaval's Party escorted Rimuru to the Kingdom of Ingrassia and found lodging to stay the night, they let Rimuru stay the night alone in a room with Eren, who they are bodyguards for, proving that they have deep trust in Rimuru, though they might also be minding social status, as Rimuru was the head of Tempest and Eren was a ducal princess ,while Kaval and Gido themselves where just guards.


 * Fuze
 * He's a Guild Master of the Free Guild. Rimuru and Fuze have an interesting relationship, Rimuru saw that by forming a relationship with Fuze he can have better relationships with humans. While Fuze views it as a way to avoid a fight with a monster nation. While Fuze is skeptical about everything and does fear Rimuru due to immense power, even more, when Rimuru becomes a demon lord. Despite all the fears Rimuru himself trust Fuze even giving important information that Yuuki Kagurazaka was behind many major events.

City of the Forgotten Dragon

 * Milim Nava
 * After Rimuru defeated the Orc Lord, Milim became interested in him after seeing him in one of Clayman's recording crystal-balls. She immediately wanted to meet him. Despite the huge difference in power, Rimuru was able to somewhat tame the Demon Lord by feeding her Apito's Honey and learns to control Milim like how one disciplines a child or at least that's how it appears to Rimuru, as he wasn't aware of Milim's cunning side at the time yet. The two started to see each other as friends but Milim went further to declare that they were now "Besties" causing the Tempest citizens to cheer. Rimuru cares for Milim and was worried when he believed Clayman was controlling her. He began to view her in a new light when he realized that she had pretended to be under Clayman's sway to outsmart him in order to learn of his plans and co-conspirators. Rimuru is often overwhelmed by Milim's power and unpredictableness.

To Milim, Rimuru is her "only friend" which means that she doesn't even really view Guy and Ramiris as such, though that might possibly be due to them taking up more of a mother and father role for her. Before Rimuru became a Demon Lord, Milim offered him to become one via her recommendation, likely due to her past experiences with her pet dragon giving her the impression that she can't be there to protect those close to her all the time and that they need to obtain power themselves in order to live a safe life.

After Mariabell unleashed the Chaos Dragon that Milim had previously sealed, which was infact the soulless undead corpse of her pet dragon, Rimuru was able to resurrect the pet dragon via a simulated soul like what they use for the Dungeon Diving avatars, allowing Milim to reunite with her long-lost pet again, which then received the name of "Gaia" and participated together with Rimuru's group of four playmates in the avatar labyrinth diving, but as it was still relatively weak, it participated as itself instead of using an avatar.

Kingdom of Ingrassia

 * Shizue Izawa
 * Though she and Rimuru met each other not for long, they have developed quite a bond with each other after discovering themselves being fellow Japanese Otherworlders. Shizue had been prophesized to be Rimuru's "fated person" before he met her. With her having been absorbed by Rimuru, the prophecy came true. She requested to be absorbed by Rimuru and entrusted him with reminding Demon Lord Leon Cromwell of her existence, as well as with saving her students as she was dying after Rimuru saved her from being taken over by the Greater Elemental of Fire Ifrit. Rimuru swore to fulfill her final wishes. After absorbing Shizu, Rimuru's human form is similar to that of a younger Shizu, albeit with silver hair and golden eyes.


 * Yuuki Kagurazaka
 * Yuuki is grateful to Rimuru for letting him read a lot of manga, saving the children from the S class, and bringing peace to the Jura Forest. Yuuki claims that he would back Rimuru if there was a conflict against the Church. However, after being ambushed by Hinata, both Rimuru and Raphael suspect Yuuki being the one who tipped Hinata off that he was a monster who killed Shizu but doesn't act on it unless they have more evidence.

S Class

 * Tiss
 * To Be Added.


 * Kenya Misaki
 * His second teacher in this world and the savior of his life.


 * Gale Gibson
 * His second teacher in this world and the savior of his life.


 * Ryota Sekiguchi
 * His second teacher in this world and the savior of his life.


 * Alice Rondo
 * Her second teacher in this world and the savior of her life. She develops a huge crush on him along with Chloe.


 * Chloe Aubert
 * One of the children that was entrusted by Shizu to Rimuru and later became one of Rimuru's first students. Initially, just like the rest of the children, Chloe was wary of him. However, as Rimuru made efforts to become closer to them and teach them properly, all of them became close and respect Rimuru greatly, calling him "Professor". Among those children, Chloe becomes the one with the most affection towards Rimuru as she falls in love with him, even declaring she loves him though Rimuru didn't take that seriously initially but cares for her greatly even stating he wish she said that to him if she was 18 or 20 years older from now. As time passes their bond continues to grow. Rimuru even decided to give his treasured mask to Chloe for the reason that it felt like the "most natural thing to do."

Holy Empire Ruberios

 * Hinata Sakaguchi
 * At first, she loathed Rimuru for the simple fact that he was a monster and his existence went against the teachings of the Church while also being fooled by the merchants from the Eastern Empire into believing that he had killed Shizu. Rimuru was wary of Hinata after learning about her, but also desired to meet her because she was Shizue's student.

She tried to ambush and kill Rimuru but failed when Rimuru faked his death in their fight. Even after learning the fact that Rimuru not only survived but was telling the truth to her about being a Reincarnated Otherworlder who did not murder Shizue, she regretted the situation where she neither managed to build good relations, nor eliminate the threat, but instead had given a bad first impression to Rimuru who survived and became much stronger.

During their second battle, it was revealed that their conflicts were all orchestrated by the Western Holy Church's Clerics of the Seven Luminaries and the string-pullers of the Eastern Merchants that sold Hinata false information. After the battle ended and three out of the seven Luminaries tried to make use of Rimuru's and Hinata's exhaustion to get rid of both of them, Hinata took an attack meant for Rimuru. Rimuru was able to block all their follow-up attacks and was about to counter-attack when Hinata's boss, the Demon Lord Luminous Valentine appeared and after some negotiations there was finally peace between Rimuru and Hinata.

When Hinata blocked an attack aimed at Chloe with her body, it triggered the activation of Chloe's Unique Skill Time Travel, which pulled Hinata's soul into Chloe's body who then traveled 2000 years into the past. During this time Chloe's talked a lot about Rimuru, causing Hinata to also develop feelings for him.

Farmenas' Administration

 * Youm Farmenas
 * Meeting Rimuru for the first time when Youm got conscripted to lead the "Frontier Expedition Force" and ran into Fuze's group that got chased by a Knight Spider and finally got rescued by the Gobta-led Goblin Riders, Youm was skeptical about the idea of Rimuru, a slime, leading a whole group of strong-looking Majin. But Youm, who was keenly aware of corruption and disregard of the common people by the nobles, quickly came to like the forthcoming Rimuru and the festive nature of Rimuru City, agreeing to join Rimuru's forces and participate in Rimuru's plan for Youm to take the credit for the defeat of the Orc Lord to improve relations between Tempest and humans.

During the attack by the Kingdom of Falmuth, Youm and Grucius begged Rimuru to spare Mjurran who had casted an Anti-Magic Barrier in Rimuru City at the worst possible timing on Demon Lord Clayman's orders. Youm was in conflict because he was grateful to Rimuru but couldn't leave Mjurran alone, who he fell in love with, so when Rimuru seemingly decided to kill her, Youm chose to first run away with Mjurran and try to calm Rimuru down afterwards, but the issue ended up getting resolved when Rimuru reveals he only pretended to kill Mjurran to fool Clayman and explained to him that Clayman blackmailed Mjurran with Youm's own life. When asked why Rimuru saved Mjurran, one of the reasons Rimuru mentioned was needing Youm's help later, so he didn't want to astrange him with her death.

The "help" Rimuru wanted from Youm turned out being Youm participating in a scheme for Youm to eventually take the Falmuth's throne. Under Diablo's direction, the scheme succeeded and the Kingdom of Falmuth became the "Farmenas Kingdom" with Youm picking up the name of "Youm Farmenas" with Mjurran becoming the queen under the alias of "Mjur Farmenas". The reason is because behind the scenes, Youm was still Rimuru's vassal, the Farmenas Kingdom became a de-facto vassal nation of Tempest.


 * Mjurran / Mjur Farmanas
 * She holds respect for Rimuru not only as a leader but also as the person who gifted her with her freedom and a second chance at life.

Falmuth's Administration

 * Razen

Octagram

 * Leon Cromwell
 * Rimuru initially holds contempt towards Leon for his actions towards Shizu, but upon meeting him for the first time at Walpurgis, since Leon at least seemed to have instantly recognized Rimuru's human form's likeness to Shizue, he was willing to postpone the issue until they meet privately without all the other Demon Lords around, agreeing to Leon later sending him an invitation.

However before the invitation can even be sent, they reunite in Ruberios during Granbell's revolt. Leon and Rimuru are baited to attack each other but they see through the ruse, coming to a silent understanding while pretending to have a battle against each other while looking out for any hidden assailants. They end up too cautious, however, as the only hidden assailant ended up being Tear who is not much of a danger to either of them, with their inaction causing things to escalate, with Hinata dying and being sent to the past together with Chloe to become the Hero Chronoa 2000 years ago, after which the present-day Hero Chronoa, whose frozen body Yuuki tried to steal for his own purposes during the chaos, awoke from her slumber with the Manas Chronoa in control and a started attacking anyone in sight without regards for their identity. But with the help of Veldora and Leon, Rimuru is able to first fend off and eventually calm down the Manas Chronoa, and with Raphael's help combine the rampaging power into Chloe's new Ultimate Skill Yog-Sothoth, ending Chronoa's rampage. While Luminous who finished off Granbell on her end, helped to revive the dead body of Hinata after Rimuru extracts her consciousness from the Hero Chronoa's body back into her own. Leon on the other hand finally got reunited with his childhood friend Chloe who he had been looking for all this time.


 * Guy Crimson
 * Guy sees Rimuru as a fascinating curiosity because he managed to get Ramiris to help him against Clayman, is very close to the Storm Dragon Veldora, and managed to aquire an Ultimate Skill. Guy also likes the fact that Rimuru is known as someone who can come up with names, as the Demon Lords often had problems to come up with a name for their group, so after Walpurgis and Clayman's death, Guy friendily requested Rimuru to come up a name for their Demon Lord organisation after Clayman died, Carrion and Frey retired, and Rimuru joined, but implied that he would not take a "no" for an answer, so Rimuru came up with the organisation name "Octagram" which the members liked and was thus used as their new organisation name from that point onwards.

But Guy wasn't trusting Rimuru unconditionally, so in order to convey that, he sent Dino to Rimuru as a sort of "open spy" who does not intend to hide his job.

During Granbell's rebellion, Guy came to Ruberios as well. Guy wanted to know from Diablo why he served Rimuru and stated that Rimuru's actions with the Council of the West were upsetting the balance of the world. Guy schemed to irreversibly ruin the efforts of Tempest to join the Western Nation Council by having Misery be summoned into the on-going Western Council session that was finalizing the agreement. However, it failed as Testarossa was present as Tempest's Ambassador, which prompted Misery to leave without doing anything as she was not willing to face her in battle. Guy ended up shocked as he learned from Diablo that not just Testarossa, i.e. Blanc, had joined Tempest, but also Violet and Jaune, now known as Ultima and Carrera. Guy started to wonder if Rimuru had to be insane in order to do something as daring as naming four Primordial Daemons.


 * Luminous
 * Luminous is conflicted in her feelings towards Rimuru, but still holds him in mostly positive regard. Despite their differing ideologies on how to handle their population, Luminous can get along with Rimuru himself quite well, but she also holds some jealousy over the fact that Rimuru takes so much of Chloe's attention. She is however grateful that Rimuru mostly holds "that damn lizard" at bay and prevents any new rampages from happening and is tactful enough to use his influence on Veldora to give her an opportunity to vent her frustration against Veldora directly without allowing him to fight back.


 * Dino
 * Dino, after getting kicked out from Dagruel's home, was sent by Guy to "openly spy" on Rimuru. Rimuru could not do anything about it, so he sent Dino to help with Ramiris research so he could at least be useful. He sees Tempest as a great place to loaf around but kept being shocked repeatedly by some of the absurd things that Tempest is creating, escpecially when learning about Rimuru naming multiple Primordial Daemons.


 * Dagruel
 * To Be Added.

Other Demon Lords

 * Clayman
 * Clayman was not too troubled by Rimuru ruining his plans of creating a puppet Demon Lord as Clayman received new opportunities from it as a consequence, like being able to sell Frey a favor, which he then used to make her help with trying to control Milim with a pendant called "Orb of Dominion" given to him by his creator Kagali, aka. former Demon Lord Kazlim. The plan seemingly succeeded after which Milim appared to be under Clayman's control who then made Milim attack Beast Kingdom Eurazania. Although she took some unexpected actions, overall succeeded, by pulverizing its capital city and Demon Lord Carrion being presumably dead.

Another opportunity for Clayman from Rimuru's victory over the Orc Lord was that he could set up a war with the Kingdom of Falmuth using his own backer's help in order to obtain enough souls to awaken into a True Demon Lord. The incitement was successful and the Kingdom of Falmuth began invading Tempest, while Clayman sacrificed Mjurran to further cause chaos and make the war more bloodthirsty, Clayman's plans ended up failing, supposedly due to the blood shed in the war causing the Storm Dragon 's seal to break, with Veldora supposedly annihilating all 20,000 Falmuth soldiers and knights, only to be pacified by Rimuru and the Champion Youm. Clayman was dismayed over the fact that no souls were left behind that he could use for his awakening.

Convinced that his awakening plan is still salvagable on the Eurazania side, he sends his "Middle Finger" subordinate Yamza to kill the Eurazania remnants, while heading to the Walpurgis that he himself convened. There it got revealed that Clayman was played by both Milim and Rimuru. Milim, in cahoots with Frey and later also Carrion, who was still alive, made Clayman believe that he really controlled Milim, but he did not at any point of time actually control her. On Rimuru's side, Rimuru only faked Mjurran's death to fool Clayman and Rimuru himself even awakened as a True Demon Lord and was the true culprit of the Falmuth army's deaths. Rimuru was also very angry about all of Clayman's actions surrounding both his own and Milim's side of the incident, not even including the grudges the Puppet Demon Lord plan entailed. Ultimately Rimuru, upon Raphael's suggestion, even helped Clayman to "pseudo-awaken" in order to replenish and gain more magicules from absorbing Clayman. Their final fight between Rimuru and Clayman was one-sided and Rimuru broke Clayman's will to fight, after which Rimuru used Beelzebuth to absorb Clayman along with his soul, not allowing him to use any of the tricks he learned from Kagali to escape, nor to return to the cycle of reincarnation, causing Clayman to irreversibly perish.
