Rimuru Tempest/Relationships

Tempest
The country of Tempest was found and established by Rimuru with him as its King. Every single monster living within it, from soldiers to citizens to the Executives, swear absolute and eternal loyalty to Rimuru due to his nature and charisma. Many of them even worship him as their God while others idolize him as one of the top idols of Tempest. On top of that, if a single sign of insult and disrespect, much less actual insult and disrespect, is shown to their King, the perpetrator is bound to induce their wrath. Rimuru himself has a great deal of respect to his citizens. When his citizens died due to an attack, Rimuru was full of pain and anger to the point that he decided to massacre the nobles of the Farmas Kingdom to revive his citizens.

True Dragons

 * Veldora
 * Rimuru and Veldora became fast friends after meeting each other and are now best friends with each other. Veldora has such a great amount of trust in Rimuru that he allowed Rimuru to devour him the first time in order to be freed from his sealed prison. When Veldora was captured by the Eastern Empire, Rimuru felt great anger that he never felt before, indicating that he cares deeply for his partner. Since they named each other, Rimuru and Veldora consider themselves partners. It has been said that they are akin to adoptive brothers. Rimuru also uses Veldora as a sword later on.


 * Velgrynd
 * She originally started as an enemy towards Rimuru when Rudra kidnapped and brainwashed Veldora. This made Rimuru fly into a rage and proceeded to destroy the Eastern Empire. Velgrynd completely feared Rimuru's power and saw that the rumor that Rimuru relied on Veldora to be a Demon Lord was a farce and that the sentient slime was a force of nature himself. Her fear for his power lessened and turned to hate when she thought Rimuru devoured Veldora but it quickly reverted to extreme fear when Rimuru used Veldora Sword to sliced the sky, land and the ocean in half. When she founded out the truth about Rimuru and Veldoras true relationship which was that of equals and brothers in arms, she grew to respect Rimuru although she still gets exasperated at his intelligence and constant growth. Rimuru meanwhile respects her as Veldora's sister and as an individual.
 * A Soul Corridor was established between Velgrynd and Rimuru after she was devoured by Rimuru using Ultimate Skill Gluttonous King Beelzebub. Due to Soul Corridor and Food Chain, Rimuru has acquired Scorch King Velgrynd.

Velgaia

Rimuru was instrumental in his resurrection/creation/birth. Rimuru even named the young dragon and a soul corridor was established. Rimuru saw that despite her upbeat attitude, Milim was lonely and missed her friend. Velgaia has yet to speak but has shown a favorable attitude towards Rimuru.

Velzado

Velzado respects Rimuru for his relationship with her brother and with Guy Crimson. She sees in him the same strength that was possessed by her brother Veldanava. She is curious to see just how strong he will get. She is grateful for his assistance to Guy for the evolution of his demon lord subordinates. However, she sometimes views him as a suspicious and weak slime due to his nature but it changed into respect after Rimuru destroyed Yuuki.

Goblins

 * Rigurd
 * The village chief of the first goblin village that Rimuru met and saved. After being saved and named by Rimuru, he swore the entire village's loyalty to Rimuru, becoming his first subordinates. As a Goblin King, he is entrusted by Rimuru in the governance of the country and its internal affairs, which he performs dutifully. Rigurd is also the first monster that Rimuru named. He has also been named the Ambassador of Tempest.


 * Light Novel Rigur
 * The second son of Rigurd who, like his father, is also extremely loyal to Rimuru as one of his first subordinates.


 * Ririna
 * She is entrusted by Rimuru to manage Tempest's production affair as its supervisor. Like all of the citizens of Tempest, she is also extremely loyal to Rimuru.


 * Gobta
 * One of the few Hobgoblins that have the most interactions with Rimuru himself. Rimuru regards Gobta as a genius though quite an idiot at the same time. Nevertheless, Rimuru trusts him and considers him among his most trusted subordinates as Rimuru appointed Gobta to be the Commander of the First Corps. During the Evolution Ceremony, he was granted the "right" to address Rimuru casually, indicating that Rimuru considers him as close as friends.

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 Dwarven Kingdom and being exiled from the Kingdom. He helps Rimuru a lot in developing the foundation of Tempest.


 * Garm, Doldo, Mild
 * Three brothers that worked with Kaijin and sided with Rimuru during his court hearing when he went to the Dwarf city. 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 city.


 * Gazel Dwargo
 * Rimuru first met Gazel during a trial set up by Bester but already knew the truth. He exiled Rimuru and Kaijin from Dwargon. They don't meet again until Rimuru establishes Tempest. Gazel is the first king to acknowledge Tempest as a nation. Rimuru and Gazel have a strong friendship both share the same swordmaster "Hakurou." When Rimuru became a demon lord without hesitation Gazel continues to trust Rimuru. During the Knight Templars attack on Tempest, Gazel was the first one to offer his assistants to Rimuru but decline. During the Tempest Tournament, Gazel was the only king to talk to Rimuru. Rimuru himself was grateful to have a good friendship with Gazel.

Vesta

Vesta was at first an antagonist towards Rimuru as he was jealous of Kaijin. After being exposed as a liar and fraud, he is banished from the Dwarven Kingdom. He 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 and has contributed to many of the magical and technological advancements of Tempest. Those advancements include a camera, a train, and a passenger airship.

Kijin

 * Benimaru
 * Benimaru is one of the most loyal servants of Rimuru. Both of them have a very good Master-Servant relationship. He is content with his current position with Rimuru as the Lord he serves. As one of the military commanders, he merely wishes to rampage to his heart’s content. In addition, there is a deep trust between them.


 * Souei
 * Similar to Benimaru, Souei, and Rimuru also has a deep trust between each other as Rimuru always entrusts Souei for intelligence gathering. For Souei, serving under Rimuru fills him with the highest of pleasure as he has wanted to serve under someone who he deems worthy. Between the two of them, Rimuru taught Souei the basics of being a "Ninja," making Souei who he is now. Souei has a steel thread that connects directly to Rimuru for analog communication and detection. He is the only one with this honor.


 * Hakurou
 * One of the most loyal servants of Rimuru and out of all of them, Hakurou is probably the one Rimuru respects the most as Rimuru considers him as a grandfather-figure for him as well as for Tempest. Rimuru learns and improves his sword techniques from him. Through Hakurou, he understands that the dependence on magic alone in a battle is a recipe for defeat. It was the skills he learned from Hakurou that allowed him to survive against Hinata.


 * Shion
 * Shion is the 'secretary' and bodyguard of Rimuru. They first met when she and her fellow ogres mistaken Rimuru to be one of the masked magic-born responsible for the destruction of their home due to him being in human form and was wearing Shizu's mask at the time. After Rimuru subdued them easily and showcase his overwhelming power, the ogres realized that he was not one of the masked magic-born and asked for forgiveness. Originally Shion and the ogres formed a temporary contract with Rimuru being his mercenaries in exchange for shelter in Tempest but after Rimuru named all six of them and that his identity as a slime was revealed due to the sleep mode activation (which caused them to freak out and stare with disbelief that a weak creature was ten times stronger than all of them), Shion and the ogres decided to become Rimuru's devoted servants. Since then, she fell in love with Rimuru and constantly compete 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 had made him feel exasperated at times. Rimuru cares for her so deeply that when he found out that she died, he became depressed and heartbroken that his 'naive rules' got her and one hundred citizens killed by the Farmes Kingdom and The Otherworld Trio. He was also extremely aggravated and angry. When he heard that becoming a Demon Lord could revive them, it became his sole purpose for becoming one and slaughtering the Farmes Army. Since her revival, she became more ruthless to her enemies and originally felt envious toward anyone who has Rimuru's attention but after Rimuru abolished her to forgive the Holy Knights, she realized that she competed for Rimuru's attention because she was afraid that Rimuru would forget her but realized that he would never. Since then, she became wiser and calmer and due to wanting to improve her cooking to please Rimuru, she obtained the Unique Skill 'Cook' which made her food good although her bad prep work would still incur Rimuru's annoyance. After the war, she competes with Shuna, Millim, Chloe, Ramiris, and Ciel for the position of Rimuru's legal wife in the web novel and often fights with Shuna for who gets to wake up Rimuru.


 * 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 in regards to Tempest's Department of Production. Because of Rimuru's kindness, she falls in love with him. After entrusting and passing all of her skills to the Department of Production. Shuna becomes Rimuru's full-time secretary, which he appreciates the most since Shion is busy and quite a disappointing "secretary." This has Rimuru sometimes entrust Shuna on negotiations with other nations. She struggles daily with Shion in Rimuru's bed over who gets to wake him. Rimuru comes to care deeply for Shuna's well being that whenever a battle approaches, he takes measures to ensure nothing would happen to her.

The two have often chatted about making new armaments for Tempest based on Rimuru's ideas. He endeavors to create the perfect weapon for his Lord Rimuru.

Demons

 * 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 in order to impress and prove his loyalty to Rimuru, such as forming the Black Corps - 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. In a separate adventure, it is stated that Diablo administered Endless Pain on the man who murdered Satoru, Rimuru's previous incarnation. Diablo has begun to display a lot of Rimuru's Skills (but to a much lesser degree in power) much to Rimuru's delight and surprise.

Humans and Otherworlder Humans

 * 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 World Travelers. Shizue had been prophecized to be the one Rimuru would spend the rest of his life with. With her now being a permanent part of him, the prophecy came true. Shizue is fond of him and trusts him deeply due to his nature, to the point that she requested to be absorbed by Rimuru and entrusted her students to him as she was dying after Rimuru saved her from being taken over by the Fire Spirit Ifrit. Rimuru is also fond of her as he addresses her as Shizu and strives to fulfill his promise to her. After absorbing Shizu, Rimuru's human form is similar to that of a younger Shizu, albeit with silver hair and golden eyes. It seems Shizu's spirit continues to linger within Rimuru as some sort of a guardian spirit or conscience for him.

Hinata

At first, she loathed Rimuru for the simple fact that he was a monster and his existence went against the teachings of the Church. Later she believed 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 later realized that Rimuru was a being that truly cared for his subordinates. During their second battle, Rimuru removed Yuuki's influence from Hinata and freed her of her cold demeanor. She eventually began to have affection for Rimuru and thinks more highly of him. This has sometimes made her feel less capable compared to him for those she cares for like Shizue and her students by how he was able to help them more than she ever could. Despite their initial encounter and impressions, Rimuru becomes very casual and friendly towards Hinata and this bond is strengthened in their shared desire to help Shizue's students, especially Chloe.

Ellen

Rimuru is grateful to Ellen as she is the one who pointed out the ritual to revive Shion and the other fallen citizens of Tempest. Ellen is also instrumental in developing diplomatic relations with her home country, Sorcerer's Dynasty Sarion. She was one of Shizu's dear companions and one of the first human's he met on this world. Ellen eventually permanently moves to Tempest.

He was one of Shizu's dear companions and is one of the first humans that Rimuru met in this world. He is fond of the entire party. So much so that he gifted them valuable weapons and armor. Gido had a grasp on Rimuru's power before he ascended to a True Demon Lord and thought he was absurdly powerful then. As it stands now, he is eternally grateful to be in his good graces now.

He was one of Shizu's dear companions and is one of the first humans that Rimuru met in this world. He is fond of the entire party. So much so that he gifted them valuable weapons and armor.

Youmu begged Rimuru to spear Myulan and Grucius life as they were found out to be spies for other demon lords. Rimuru decided to make Youmu the new hero of Farmas Kingdom and make the Farmas Kingdom a vessel state.

Labyrinth Executors and Monsters

 * Kumāra
 * Zegion
 * Zegion first met Rimuru when he was trying to protect the weaken Apito when she was injured by a Blade Tiger. He originally thought Rimuru was an enemy and although injured himself, he tried to attack him but stopped when Rimuru told him he was not an enemy and healed Apito and Zegion due to Rimuru's interest in Zegion's design. Since then he became one of his most loyal retainers and is considered a part of the three strongest retainers in Tempest after Diablo and Benimaru. He worships Rimuru like a god and was the only two retainers that didn't lose his cool when Velda pronounced Rimuru dead, scoffing at the thought of Rimuru losing and berating the other retainers for panicking. However, anyone who insults Rimuru or destroys his image will incur Zegion's wrath as shown when the knights of the Eastern Empire mistaken him as Rimuru, angering Zegion greatly that being compared to Rimuru is an embarrassment to Rimuru's strength and image, destroying all the strongest knights in less than a minute.


 * Apito
 * Apito first met Rimuru when she was injured by a Blade Tiger and was protected by Zegion. Rimuru decided to heal her due to her and Zegion's unique design. She then serves Rimuru and helps supply him with honey. After she evolved to a more beautiful and feminine form, she became one of his strongest fighters. She is very loyal to him and may even harbor some feelings towards him.


 * Adalman
 * Adalman first met Rimuru after Shuna defeated him. He originally was a servant (albeit controlled by Clayman) until Shuna used Holy Magic due to her undying love and respect towards Rimuru and defeated him which caused him to wonder about his loss of faith towards his God as the Seven Sages sent him on a death mission and caused to be a lich. Since his defeat, he wishes to meet Rimuru and hopefully, he can become his servant. After meeting him and learning the fact that not only was he a slime albeit an insanely powerful one, spared two of Clayman's Five Fingers (Kumara and Mjuran) and helped made the Jura Forest more prosperitable, he saw Rimuru as a being of worship and became one of his most devoted followers and one of his strongest retainers.

 * Gozurl
 * At first, he believed himself stronger than Rimuru. Rimuru thought he looked like a Minotaur and immediately wanted him for the Labyrinth.

Rimuru saw and appreciated his strength and decided to make him a floor boss in the Labyrinth.


 * Mezurl
 * At first, he believed himself stronger than Rimuru. When he realized how absurd that notion was, he attempted to get Rimuru to side with him against his enemy of 100 years.

 * Notos


 * Euros

Death Dragon

 * Wenti

Others

 * Great Sage/Wisdom Lord Raphael/Ciel: Manas (God's Wisdom Core)
 * Has been with Rimuru Tempest from the beginning as a Skill, over time it started becoming self-aware and Rimuru having great trust in the Skill assisting him that allowing both to grow strong once called Great Sage was later called Wisdom Lord Raphael now has been given her name Ciel by Rimuru and becoming aware to its individuality. Later on, in the web novel, Ciel tells Rimuru that she is the "official" wife of Rimuru, when Chloe, Shuna, Milim, and Shion fight over the position of official wife Rimuru
 * Manas: Chronoa
 * Chronoa met Rimuru in another timeline where he did not have an encounter with Hinata and Shion didn't die. In her timeline, Rimuru was detained by Chloe because she did not want him to leave so he immediately teleported straight to Tempest instead of traveling there as Chloe (in the current timeline) want Rimuru to see her as an adult so she held back. Therefore he managed to repel the Farmas Kingdom attack but his country was utterly destroyed by the Eastern Empire and he was killed by Rudra. Normally he was supposed to be dead in most of the timelines but in this one Great Sage revived him. Despaired by his country's destruction and his people's death, his skills evolved into Ultimate skills similar to the current Rimuru's skills minus Storm King Veldora and Covenant King Uriel. He immediately destroyed the Farmas Kingdom without sparing anymore and became an Awakened Demon Lord. However, he still maintained his regular kind nature albeit a bit more heartless towards his enemies. When Chloe and Hinata went to the past, they called themselves under the name 'Chronoa' for their hero persona. However, Hinata had a hidden skill which didn't have a name so it became Manas: Chronoa as a third personality which represents all of Chloe and Hinata's negative emotions which were bottled up. After the souls of both of them left due to their respective summonings into the other world, Chronoa was awakened. She took over the body and rampaged. It wasn't until Rimuru bumped into her and took 3 days trying to stop her. After calming down, she joined Rimuru in his quest to stop the war between Guy and Rudra and stop Milim and Veldora's rampage due to losing Rimuru. She immediately fell in love with Rimuru when he was stopping her and has devoted herself to him. However, she died unknowingly in Rimuru's arms and her soul was sent to the current timeline when Rimuru was saving the children. It is implied that she was the spirit that entered Chloe and kissed Rimuru. In the current timeline when Chloe's old body was sealed it was stolen by Granbell Rosso and awakened. She proceeded to rampage and it caused Chloe to disappear and Hinata's soul was absorbed into her after she was killed by Granbell. It took the efforts of Rimuru, Leon, Veldora, Charys (Ifrit) and Yuuki (albeit an uneasy temporary truce) to stop her rampage. Then, Rimuru used Raphael to split the Mathemation skill to revive Hinata and free Chloe and Chronoa. After the incident settled down she became a Manas for Chloe. She still is in love with Rimuru and tends to be more clingy and always strike when there's a chance unlike Chloe who although loves Rimuru like Chronoa but is more reserved although Chronoa admits that the current Rimuru is ten times weaker than the one in her original timeline. She also despises Ciel as they both believed that they are the better Manas than the other and that they love Rimuru.

Ranga

Besides Ceil, there is perhaps no one who is closer to Rimuru due to his residence in his shadow. Ranga was among the first group of beings to be named by Rimuru. Due to literally living in Rimuru shadow, Ranga has constantly absorbed Rimuru's aura. He had previously experienced a transformation into a Tempest Star Wolf due to his exposures and absorption of the aura. Ranga was the son of the previous Dire Wolf boss who Rimuru killed in defending the Goblin Village. Once Rimuru transformed into a Dire Wolf and exerted his aura, Ranga and the rest of his pack yielded to Rimuru in a subservient manner.

Orcs
Extremely loyal to Rimuru has infinite gratitude to Rimuru by adopting the orcs. He was astounded by Rimuru's generosity in allowing the Orcs to be a part of the Great Jura Alliance. He will take Benimaru's word to heart to spend the rest of his considerable life in serving Rimuru as penance for his part in the Orc Lords calamity.
 * Geld

Lizardman
Gabiru is one of many who serves under Rimuru. Their relationship started off rocky due to the fact that Gabiru looked down on Rimuru due to the fact he is a slime. This changes when Rimuru saves Gabiru life from the Orc Lord. After Gabiru banishment from the Lizardman and deciding to serve under Rimuru changes Gabiru. Gabiru becomes in a proper leader leading Rimuru sky forces and even naming him "Dragon Lord". He has since swallowed his pride and realize that there are those who are infinitely stronger than him. He now understands that by serving Rimuru he will learn and grow stronger himself. A Lizardman who serve Souka's during her time as a Lizardman guard.

Giants
Rimuru originally met Dagura and his brothers outside of The Walpurgis Banquet Meeting Place. They originally picked a fight with him in order to drive him away as he and their father, Dagruel got along to prevent him from getting hurt and drive him away. However, this has been proven futile by the one-sided beating by Shion. Since then, he and his brothers worked for Rimuru to study Tempest's culture while wanting to serve as Shion's bodyguards as they were infatuated with her. Dagura's loyalty to Rimuru and feelings for Shion were enough for him and his brothers to join their side and fight their father during the war. Although, he and his brothers are slightly envious of Rimuru due to Shion being in love with him.
 * Dagura
 * Ryura


 * Debura

Demon Lords
Leon Cromwell

Rimuru initially holds contempt towards Leon for his actions towards Shizu, but after knowing how he saved Shizu, he is willing to work with him for Chloe's sake. He has even gone so far as to save Leon's life thereby beginning his evolution into a Dem-God.

Milim Nava

After Rimuru defeats the Orc Lord, Milim becomes interested in him. She immediately wanted to meet him. Despite the huge difference in power, Rimuru was able to somewhat tame the Demon Lord by feeding her honey. He learns to control Milim like how one disciplines a child. The two now see each other as friends (Milim says they're best friends). Rimuru cares for Milim and was worried when Clayman believed he was controlling her. He began to view her in a new light when he realized that she had the wherewithal to pretend to be under his sway to out him as a manipulator and usurper. He is often overwhelmed by Milim's power and unpredictableness. It is hinted that she may have feelings for him as in the Light Novel and in the Web Novel, she would compete with Shuna, Shion, Chloe and Ramiris over Rimuru's attention.

Clayman

He absolutely hates Rimuru. He believes that Rimuru usurped the position and power that should have been his as a demon lord. He views Rimuru's arrival as the reason for his plan to create and subjugate a new true demon lord failing. His actions to discredit and destroy Rimuru and his Monster Country led to his death. He disgusted Rimuru so much that Rimuru decided to kill him first and ask for forgiveness from the other demon lords later.

Ramiris

At first, Ramiris was leary of Rimuru when he destroyed her golem. She released her reservations when he created her a more powerful and intelligent protector in Beretta. She was so impressed with him, that she decided to move her entire Labyrinth closer to his city. She welcomed Rimuru's input in the construction of the new labyrinth and even accepted a job as the manager/engineer of the entire facility. She believes that Rimuru has elevated her standing by growing her number of subordinates and providing her wealth with a percentage (20%) of the proceeds of the labyrinth. She has even had her view among the other demon lords elevated. In the Web Novel, it's shown that she has feelings for Rimuru and competes for his attention. She has begun to develop combat techniques thanks to her pseudo adventuring with Milim, Veldora, and Rimuru in the Labyrinth.

Guy Crimson

Guy sees Rimuru as a fascinating curiosity. He acknowledges his power, but wonders why he does not subjugate the world. He is impressed and intrigued by his restraint. He is one of the few beings that has battled Veldanava and feels a similar presence in Rimuru when the two battle. He stated he would not seriously battle Rimuru because he is not in the habit of engaging in battles he knows he can not win. He became friendly towards Rimuru the moment he agreed to have his servants taught the technique and recipe for "cake." He is amazed at how quickly Rimuru ascended in power while believing that he genuinely did not seek it.

Dino

Dino respects Rimuru's power but sees his city as the perfect place to loaf around and eat cake. Dino is also curious to find out if Rimuru is indeed a reincarnation of his master, Veldanava. He does see in his generosity and kindness that he saw in Veldanava. He believes that Rimuru's friendship with Milim is what is best for her, even if he does get to eat and sleep well while they play together.

Ruminas Valentine

Ruminas is conflicted in her feelings toward Rimuru. Firstly he is the sworn brother of her eternal enemy Veldora, but she realizes that he is benevolent and kind.
