Rimuru Tempest

Newbie Demon Lord Rimuru Tempest. The king of Tempest.

Appearance
Rimuru appears as a silver slime with streaks of gold. As he possesses the skill Mimesis, he will appear in certain forms with distinguishable characteristics.

Fusion
He can use fire state in his slime form. Upon activating that skill, his aura becomes that of a flame. His facial temperature also raises to over 1400 degrees. It can be used as a weapon. The spider gives him white spots. As a centipede, he grows fangs. With the lizard he grows scales. As a giant bat he sprouted demon like wings. As the black wolf, he turned black and grew two horns. Horns like those of a unicorn. As a black snake, his body is covered in a gold pattern.

Mimesis: Human
In this form, Rimuru possesses silver hair. There is no sex, however, the features are more like that of a girl. Probably, because the original body was Shizu’s, his gene is nowhere to be seen. But, there are insanely cute features.

This form doesn’t use black fog, because the slime body is equal with the reaction speed. There is no discomfort. Also, because there no need for black fog, there is no need to consume magic power.

Due the fact there are limbs now, there are improvements in motor abilities, but it was a child. Still, It’s easier to move than slime. It is also possible for the mimicry to become adult.

This form has no excretion and reproductive organs, given there isn’t a need to excrete or reproduce. Since he doesn’t need to breathe, he doesn’t do it even as a human. He could create lungs if he wanted to, but since he doesn’t see a need to, he hasn’t made them. However, when wearing a mask he can pretend to breathe.

In his human form he wears a black fur coat. Under the coat he wears the kimono that Shuna had made for him. Underneath, he wears the pants he previously received. Also, steel thread underwear.

Since eating the Orc Disaster, his human form grew a bit. He was no longer a child, but a young girl. Around 150 cm in height. In addition, he obtained a devil transformation form.

Fusion

 * Flame Giant: His hair and eyes turn crimson.
 * Black Wolf: His hair turns black, with two cowlicks sticking out.
 * Black Snake: His eyes turn green and snake like. His hands and feet became covered in scales and he grows claws.
 * Giant Bat: He grows demon wings.

Abilities
Using Great Sage he can quickly read a book by copying it completely. Simultaneous utilization of Great Sage and gluttony, the high speed copy of the magic books that he holds in her hands. One 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 he wants. After this, it’s necessary for him to study it one by one.

After evolving into a demon slime, the ability to freely change between material and spiritual bodies was added. As the 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 and herculean strength.

Thanks to Hakurou’s guidance, he has gotten rather good with the sword.

Along with gluttony his stomach capacity has doubled.

Mimic
When a certain amount of damage accumulates, the mimicry wears off. Afterwards, there is no damage transfers to his slime body. It’s because the skill mimesis utilized magic essence to create a new body, which is why the main body cannot be damaged. There are two restrictions on this skill. After Mimesis wears off, he is unable to transform for the next 3 minutes, and the other was that mimicking a demon 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.

 * Kimono: It is a 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.
 * Wolf Outerwear: The materials used, came from the previous pack leader. But, due to the 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 he turns into his adult version, the clothing won’t rip.

History
Prologue: Mikami Satoru works at a major contracting firm and has never had a girlfriend. Ever. When meeting up with his junior, Tamura, Mikami takes a criminal’s blade aimed at Tamura. As he lays dying, his thoughts trigger the acquisition of six resistance skills and his two fundamental unique skills, Predator and Great Sage.

Empowerment Arc: He reincarnates as a slime, which takes some getting used to. As slimes don’t sleep and only have the sense of touch, he eats grass to pass the time. After 90 days of boredom, the skill Great Sage finally finishes integrating and things start to pick up. Turns out the Hipokte grass he ate out of boredom is material for high grade health restorative.

In the cave, he finally meets another life form, and slime meets dragon. The great Storm Dragon Veldora not only proves to be a bashful friend, but also teaches him how to perceive the surroundings via magical energy. Veldora also reminisces about the peerless beauty of a Hero that defeated him 300 years ago...the two friends also name each other. Veldora becomes Veldora Tempest, and our protagonist is Rimuru Tempest. To break the unbreakable Endless Prison, they agree to stake Veldora’s freedom on Rimuru’s unique skills, and Veldora gets stored in Predator’s 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. It was only after using the Great Sage’s mapping function that he succeeded, though. During the 30 days after meeting Veldora, Rimuru eats more grass and rocks, namely Hipokte grass and Demon ore, and develops some good 1v1 fighting skills.

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 meets a group of Goblins and gets invited to their village. Turns out the Goblins are being threatened by a pack of Fang Wolves. After hearing the situation from the village chief and being promised eternal loyalty, good natured Rimuru helps them, defeats the wolf pack’s leader, and somehow 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.

In the fantasy world, most monsters are nameless, with only high-magic power beings able to bestow names on others. When Rimuru realizes that there is no convienient way to get their attention beyond ‘Oi, you! No, not you, the one next to you, yes you!’ he names them all. The village chief becomes Rigurdo, the chief’s son Rigur, the new wolf leader Ranga, and let’s not forget goblin Gobuta, a natural boke. All the named monsters evolve, becoming stronger, but they no longer fit their clothes or their door frames, so Rimuru along with Gobuta, Rigur, and Ranga go to the Dwarf’s kingdom to acquire a clothes and a skilled house builder.

Rimuru, after some misunderstandings, helps out a masterful blacksmith, Kaijin, to fill his quota on swords per King’s request. When in doubt, ask Great Sage. Turns out the Demon ore Rimuru ate in the cave is a high class smithing material. In return, Kaijin promises to procure Rimuru a good blacksmith, and Rimuru offers to help Kaijin’s friends, three dwarf brothers very skilled at their crafts but bad at business. However, a certain Minister Bester ruins this, and Kaijin after delivering his quota must leave the country. The four dwarves, Rimuru and co. return to the village.

The dwarfs and goblins immediately start working on building housing. There’s unrest in Jura Forest, and some goblin tribes heard rumors of an odd village, so 500 more goblins join Rimuru’s team. As they begin to construct the new town, Rimuru meets three adventurers who are surveying the land in front of Veldora’s cave on the Freedom Association Branch in the small country Brumund’s behalf. The adventures are a happy bunch. A person accompanying the trio loses control of an inner flame demon shortly after meeting Rimuru, and it’s up to Rimuru to stop it. After settling the situation, Rimuru sends off the adventurer trio. Shizue, the flame demon’s retainer, is a World Traveller, originally from Japan. She was summoned by Demon Lord Leom Cromwell, and asks Rimuru to take up her revenge and become apart of his strength, which he accepts.

Rimuru can now transform into a human! A beautifully androgenous human, with an alterable age. Other key abilities include cloning, fire manipulation, and a unique skill Shapeshifter.
