Rimuru Tempest

"Great Demon Lord" Rimuru Tempest 「"大魔王" リムル・テンペスト, "Dai Maō" Rimuru Tenpesuto」, formerly known as Satoru Mikami, is the main protagonist of Tensei Shitara Slime Datta Ken.

A partner and best friend of the True Dragon Veldora Tempest, Rimuru is the founder and King of the monster country Tempest. He is regarded as one of the strongest Demon Lord among the mighty Eight Star Demon Lords and also the only proper Great Demon Lord currently.

Personality
He has a kind heart and quirky personality. Even though he is quite laid back and wants to avoid troublesome situations as much as possible, he actually works very diligently when there is a task needed to be taken care of.

With the heart of a hardworking salaryman and a beloved senior co-worker, Rimuru has a hard time rejecting someone if they plead him to help, leading in him often ending up with more work than he can handle, which his boss from his previous life used to reprimand him for.

Being the very Satoru Mikami himself, he also believes himself to be a KY-person (Kuuki Yomenai) who makes jokes at the wrong time.

Rimuru tends to react very severely when there's a danger to his close ones, such as his countrymen, subordinates, (possibly due to the soul-link he shares with them), good friends, and students (he can't stand children suffering). One might say he overreacts to these cases, but it simply shows how deeply he cares for them, as a stark contrast with his usual cheerful self.

Unlike many other shounen protagonists, he has no problems with decimating any forces who dare to harm his subordinates and his country, regardless of their numbers, realizing full-well about the deed he's done.

After a mishap of subsides, Rimuru tends to quickly revert back to his laid back self and mentally (or even in actuality) scratches his head at the scenery he caused.

He is described as cautious and cunning by other fellow Demon Lords, unaware that it is simply a means of him trying to prevent troublesome situations from going out of hand. As he progresses through the story, he slowly becomes more and more like a actual Demon Lord, and as he adjusts to the rules of the new world and understands the capabilities of his subordinates, he begins to let them handle tough situations on their own instead of voluntarily diving in first to patch stuff up.

Slime
Rimuru initially appears as a pure white-bodied slime (blue in the Light Novel, Manga, and Anime), but upon becoming a Demon Slime, his body turns silver with streaks of gold.

As a slime, since his body is androgynous, anything he mimics takes on an androgynous form of the respective creatures, while still bearing huge resemblances to the individual creatures as well.

His mass also grew over time, allowing him to accommodate larger mimicry forms without using extra magic to compensate for the additional mass. Towards the beginning of the story, he only has enough mass to appear as a child, but by the time he becomes an Ultimate Slime, he has enough mass to appear as a 16-year-old.

Mimicry: Human
In this form, Rimuru possesses silver hair (blue in the Light Novel, Manga, and Anime). There are no visible sex characteristics; however, he is often mistaken for a young girl due to the fact that the original form belonged to Shizue Izawa. But when he wears the anti-demon mask he kept as a memento from Shizu, his speech pattern can also make him seem like a prepubescent boy to others.

Unlike Rimuru's other Mimics, his hair changes color to one similar to that of his original slime body. It is unknown if this is just for convenience's sake, but it may also be possible this is because he was once human before and has a special connection to the form.

Since his slime body is equal in mass to his human form, he fills this body with solid shape instead of black fog. Without the black fog, there is no additional magic consumption required to maintain the form. There is no discomfort when he assumes this form. If he uses the black fog, he can also assume the form of an adult.

His fine motor capabilities improve when he is in his human form, and he finds it easier to move in than his slime form. Even though it appears to be human, this form has no need for breathing, excretion, and reproductive organs. However, he can freely eat, taste, and drink.

In his human form, he wears a black fur coat and a scarf. Under the coat, he wears the kimono and pants that Shuna had made for him. He also wears the steel thread underwear he makes himself. He often wears Shizu's old mask to hide his demonic powers.

Since eating the Orc Disaster, his human form grew a bit. He now assumes the form of a pre-teen with feminine features. In this form, he is around 150 cm in height. In addition, he has obtained a devil transformation.

Upon becoming a True Demon Lord and changing his race change to Demon Slime, Rimuru has been depicted wearing a black overcoat. His nails also appear sharper and his overall human form appears slightly older.

Upon evolving further into an Ultimate Slime, Rimuru's human form ages to 16-17 years old. This form is described by Velgrynd as appearing gender-less (as she saw it nude upon creation) but with dangerously cute features. By simply willing it, Rimuru can generate clothes from his own mass and magic power.

Details
Using Great Sage, he can quickly read a book by copying it completely. Simultaneous utilization of Great Sage and Gluttony allow the high-speed copy and review of the magic books that he holds in his hands. With that, he can postpone checking the content of the book for a later time. Unfortunately, it is not possible to be able to use magic just by copying the books. But, taking and copying it, he’s able to make the index of the magic books that he wants. After this, it’s necessary for him to study them one by one. Taking that into consideration, it can be said that Rimuru holds a great amount of knowledge regarding magic as well as being speculated to be able to use most of the magic in those books, if not all of them.

After evolving into a Demon Slime, the ability to freely change between material and spiritual bodies was added. As a result of the evolution, his total magical energy greatly increased. Compared to the original amount, it was ten times as large.

He can use skills that don’t rely on magical energy such as raising his abilities using fighting spirit technique with Herculean Strength in addition.

Thanks to Hakurou’s guidance, his skills with the sword was improved.

He was able to analyze the Summoning Magic he first saw during the adventurer exam and acquired the skill to use them.

After fighting the Guardian of the Labyrinth, Rimuru has the ability to create golems. The abilities of the Golem can be added through the possession a spirit or a demon as Rimuru made them inhabit the Golem. The outward appearance of the golem is created according to his imagination.

Using Manas: Ciel, Rimuru can copy space manipulation techniques simply by seeing it, such as when he copied the Unique Skill Restrainer which belonged to Gozurl. Like this, Rimuru can also copy practically any other Skill or Magic as long as he has seen it.

After the fight with Yuuki, Rimuru gained the ability to use Instantaneous Movement which lets him travel across Space-Time at will. Using this ability, Rimuru was able to travel to his old world where he saved his past self Mikami Satoru from death. He was also able to return from the place beyond time where he was exiled to by Yuuki. The ability as described is the ability to reach the desired point instantly across space and time.

Transmigrant people from another world would retain half of their memories at best if they're lucky while Rimuru is a Transmigrant from another world but he retains all of his memories which showcase how strong his willpower.

Beretta is twice as strong as the Elemental Colossus who is stronger than the Sky Dragon, which is on Ifrit's level before Veldora's training. Can harm Orc Disaster Geld, who tanked a pinpointed version of Ranga's Death Storm. Became far stronger after absorbing Orc Disaster Geld and Charybdis, as well as training under Milim Nava) Gluttony will eventually become Planet level (Rimuru can integrate Gluttony with his clone that can grow large enough to devour a planet) | Continent level (Comparable to Leon Cromwell, whose fight against the Yellow Primordial would result to the destruction of El Dorado, a continent larger than Australia. Comparable to Carrera, the named Yellow Primordial, who can destroy the Great Jura Forest which is larger than El Dorado), Beelzebub will eventually become Planet level (Beelzebub, Lord of Gluttony is a combination of Gluttony and Merciless. Rimuru should be able to integrate Beelzebub into one of his clone that can grow large enough to devour a planet)

His speed should've improved significantly after training under Milim Nava), Massively Hypersonic+ with Black Lightning, Speed of Light with Megiddo (Can use over a thousand or so droplets of water as convex lenses which gather sunlight honing it into thin rays of light and refracting it against the mirrorlike droplets. This focuses all the light upon a single point, where it was then further condensed by the convex-lens droplets down below Rimuru before being channeled toward its target at the speed of light) | Relativistic+ (Comparable to Saint Hinata Sakaguchi who displayed incredible speed despite Rimuru's Mind Accelerate boosting his perception speed a million times, describing her to be comparable to Milim Nava.

Stamina: Physically limitless, as a Slime he doesn't get tired or need to sleep.

Range: Tens of Kilometers | Tens of Kilometers

Standard Equipment: Anti-Magic Mask, Magic Coat, Katana, Demon Lord's Ring

Intelligence: Extraordinary Genius (Rimuru/Great Sage can analyze all non-concealed phenomenon, estimate the chances of him succeeding at any task, and record and accurately copy the contents of entire books to his mind within seconds. These books would have taken even experts of magic lifetimes to learn. Hence, his knowledge in the field of magic and magic science surpasses the expert and Rimuru is one of the smartest characters in his world. He understood the concept of how Magic Researcher, a complicated Golem built with spirit magic, works physically which is something that the best of mind of the Dwarfs and the elves couldn't do and had to give up on. The project was solved by the fairies and Ramiris, and Rimuru was able to make a much better improvement to Golem's concept with his creation that served as a basis for Beretta's body, with his methodology far outclassing what was made by the fairies. Under extreme pressure Rimuru with the help of Great Sage, calculated all the light position requirements for Megiddo's attack that required processing several hundred thousand floating water droplets as one of the main variables that he uses for it. From the creation of Megiddo, Rimuru created a new field of magic called physic magic. Great Sage can also predict the future from calculations alone) | Extraordinary Genius (Far smarter than before. Rimuru/Raphael's intelligence is beyond the realm of mortal intelligence and has the processing power to out-compute a quantum computer easily, and is more economic and precise than a supercomputer. Raphael is far more cunning and always gives Rimuru the best outcome in a given scenario. It’s capable of planning ahead of time and will warn Rimuru to the events that are taking place even if they're from unknown places)

When a certain amount of damage accumulates, the mimicry wears off. Afterward, there are no damage transfers to his slime body. Because the skill Mimicry utilizes Magic Essence to create a new body, the main body cannot be damaged. There are two restrictions on this skill. After Mimicry wears off, he is unable to transform for the next 3 minutes, and the other was that mimicking a demon/monster required a certain amount of magic essence. The amount of magic essence required is relatively insignificant, hence, it is not an issue, and there is no duration limit to the skill. The reason for black fog when mimicking into monsters is to compensate for the missing parts.

Fusion

He can use the skill『Fire State』 in his slime form, allowing his aura to turn into flames. His surface temperature increases to 1400 degrees Celsius and his body becomes a weapon.

Equipment
A magic mask left by Shizue Izawa. As its name implies, it suppresses demonic power. It also serves as a treasured memento of Shizue, as it is the only remaining possession of Shizue which Rimuru possesses. He received dark leather guards from Garm. It is made of glossy linen - first-class silk that feels wonderful to the touch. Putting the silk to his body, it immediately changes size to fit him. After mixing with his magic, it became as if a part of his body. Even in his adult form, the clothing grows appropriately. This clothing absorbs the aura of its wearer and can change its appearance. Rimuru’s clothing turned jet black to match his aura. Even if this clothing rips, as long as it absorbs his magical energy, it can repair itself. The materials used came from the previous Fanged Wolf leader. But, due to the wolf clan’s evolution, the fur had turned black. As an extra bonus, it seems that the fur had quite some magical energy stored in it. It has tremendous defense power. This attire happened to have become a magic item. It will always perfectly fit the one who wears it. In other words, even if Rimuru turns into his adult version, the clothing won’t rip. Rimuru equipped with a demon sword a Magic Swords a high-purity Demon Steel weapons inserted with high-purity magic stones/gems he created a sword using Bladed Storm Crystallization and Bladed Flame(Scorch): Crystallization from Void God Azathoth call The Sword Of Tempest.
