Slime: Before Rimuru’s evolution, he was a round blue Slime.  After turning into a Demon Slime, his shape remained but the light blue color turned to silver with stripes of gold. One of the attributes of the body of a slime is its ability to mimic the shape and size of any creature (Manga: Chapter 1).

Human: Rimuru’s human form looks like Shizue Izawa, the human he absorbed. He has shiny blue hair that can look silver from time to time, golden eyes and pale skin. He is genderless but those who do not know him will refer to him as a young girl (Manga: Chapter 10).

Even though Rimuru can turn into a Human, none of the physical attributes or necessities of a human body is retained. It is just a morph. He doesn’t need to breathe, eat or drink and he cannot reproduce. He will often be seen enjoying food just for the pleasure of its taste.

He will most of the time be wearing a blue coat along with a white scarf. Under it is a kimono and pants. His clothes were designed and sewed by Shuna. He will also be seen with Shizue’s mask, a momentum of her death.

After evolving and acquiring the title of Demon Lord, his wardrobe will turn into a black overcoat and he will start to look a bit older. Overall, Rimuru is more Kawaii than handsome because of his small body. It is expected that he will turn into a heart-breaker after evolving some more.


A gentle soul always smiling and energetic. Rimuru is the type of person to always extend a helping hand to those in need. Leaving no one behind, he will go to great lengths to protect the weak and of course his friends.

He can be lazy and acts like he would prefer to avoid bothersome circumstances but at the same time, he is always the one to bring those circumstances to him willingly. It is because of this attitude and the fact that he will turn his back on no one that he gained so many powerful and trusted followers.

He can be insensitive at times and fails to read the situation and ends up throwing jokes and the worst moments.

He can’t stand to see someone suffer and gets enraged when the lives of those he loves which means most of his countrymen are in danger. He begins by trying to avoid taking the soul of another as much as possible but ends up killing 10,000 people in order to become a Demon Lord and revive those who died during Falmuth’s invasion of Tempest (Manga: Chapter 165). 

Rimurus’s greatest issue is his extreme anxiety. He thought that all his trusted friends would abandon him after he revealed to them his true identity as a human and an otherworlder.

Also, as a leader and a king, soon to become a reincarnated God, Rimuru is way too naive. He rushes into political decisions, believing that the other side has considered his best interest in the deal which is almost never the case. King Gazel was the one to highlight this problem to him and advised him to be more cautious (Manga: Chapter 76).

Rimuru doesn’t have faith in his strength and abilities. He always expects the enemy to be stronger and ends up carefully planning his battles while keeping his skill as a secret for surprise attacks.

Although his angelic face makes it hard to believe, Rimuru is quite shrewd. A quality he uses in making all his decisions. Among all his overpowered abilities, this one is one of the most effective. He survived his fight against Hinata Sakaguchi, thanks to his schemes (Manga: Chapter 121).

Rimuru was a human called Satoru Mikami. He was a salesman in his former life and lived normally and peacefully. One day, when his junior was making him meet his fiancé, an escaping thief stabbed him.  

As he was losing consciousness, a voice started resonating in his head asking him what he desired. Taking it as a dream or a delusion, he started asking for random stuff. He was getting cold and asked for this feeling to go away. He was in pain due to the wound and asked for the agony to disappear. 

He went on like this asking for other abilities. All the things that he asked for, got him to have the body of a slime in the world he was reincarnated in with all the skills that he demanded as he was fading away (Manga: Chapter 1).


Jura Tempest Federation


Great Sage / Raphael

Although Raphael is a skill, Rimuru talks and treats him as if he would be a friend. He is an indispensable partner that was with him from the moment he awakened in this new world. He started off as a mechanism and finally gained consciousness when, from his own free will, he integrated Degenerate in him in order to evolve.

Veldora Tempest


Veldora is Rimuru’s first acquaintance as well as his first friend after reincarnation. They became sworn brothers and share the same surname Tempest. A name that Veldora wears with overbearing pride. He ended up in his slimey form for a long time in order for Great Sage to analyze the prison he was in and free him.



It may be difficult to believe, but Rimuru and Ranga’s first meeting wasn’t the best. They started off as enemies. The direwolf clan was attacking the Goblin village that Rimuru accepted to protect. He ended up killing Ranga’s father in front of him. But it was that act that made all direwolf yield to him. Following the strong, Ranga became the most faithful servant of the slime (Manga: Chapter 37).


Gard Mjöllmile

Mjöllmile was in charge of acquiring the High Potions made in Tempest. He met him for the first time in the Kingdom of Ingraccia when Rimuru saved him from a Sky Dragons attack. He was in that Kingdom to sell Rimurus potions and upon learning each other’s identities they became business partners.

Masayuki Honjou

Masayuki is an Otherworlders just like Rimuru and he is also from Japan.

He came to Tempest to be one of Rimuru’s servants along with some of his kind. He ended up in charge of the village sky force. (Manga: Chapter 29)
