Let’s learn how to draw Rimuru “Mikami Satoru” Tempest from Tensei shitara Slime Datta Ken today!
Rimuru Tempest (リムル=テンペスト / 三上 悟) is the main protagonist of the That Time I Got Reincarnated as a Slime series. Rimuru was formerly Mikami Satoru, a 37-year-old salaryman, he was stabbed by a passing robber while protecting one of his co-workers and reincarnated in a new world as a slime, the lowest monster on the food chain. Now, he is one of the strongest Demon Lords, the founder and King of the monster country Tempest of the Great Jura Forest. He is shown in a few forms. Rimuru initially appears as a pure white-bodied slime. Upon becoming a Demon Slime, his body turns silver with streaks of gold. 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 human.
In human form, Rimuru has a bluish silver hair. He is often mistaken for a young girl due to the fact that the original form belonged to Shizue Izawa. He wears the anti-demon Shizu’s old mask to hide his demonic powers and he kept it as a memento from Shizu. Human form has no need for breathing, excretion, and reproductive organs. However, he can freely eat, taste, and drink. He wears a black fur coat and a scarf. Under the coat, he wears the kimono and pants with steel thread underwear. Throughout the story his human form evolves. After he became a True Demon Lord he change his race to Demon Slime. And after evolving further into an Ultimate Slime, he is appearing as gender-less 16-17 years old human with dangerously cute features. By simply willing it, Rimuru can generate clothes from his own mass and magic power.
Rimuru holds a great amount of knowledge regarding magic. He can freely change between material and spiritual bodies. At the beginning he is very easygoing, yet calculating, cautious and pacifist at heart. However after evolves, transformation and following events his personality is changing as well. He became more subtly malevolent with his intentions, his often pacifist nature became less dominant and he became more comfortable with killing or taking violent actions to protect the ones he cares about.
Step 1
As always all the blue and green lines are just construction lines and will be erased later so do not push on your pencil too much ^_^ I will try to be super efficient with the text so will only describe steps that require some explanation.
Make sure to leave enough free space on paper for next steps. You can see how much space you will need from the size of the paper on this picture.

Step 9
Lighten all the construction lines by “stamping” the kneaded eraser on the paper. Make sure to refer to the picture bellow as you need to ink only some parts of the construction lines.

Step 10
Wait till the ink is nice and dry and erase all the construction lines.

Step 11
To add colors, make sure to sketch the color outlines with the right color or pencil first.
If your goal is to become a real Mangaka and design your own manga characters make sure to try to draw Rimuru Tempest from memory several times. Always compare the drawing to the original and correct any mistakes you see. Do this till you are happy with the result. It doesn’t have to look exactly the same, don’t sweat the details. The point is that you get the main shapes right and that it looks good. This is the best way to build a huge library of manga shapes in your memory that you can use to draw and design your own manga characters ^-^.
Draw with passion! ^_^
