After reincarnation, he appeared as blue slime but later when he became a Demon Slime, his body is now of silver color and has streaks of gold. As he is a Slime he is androgynous, he mimics and takes on the form of respective creatures while still maintaining his individual stature.

He gains mass over time which allows him to mimic other firms without using extra magic. Initially, he only had enough mass to appear as a human child but every time he consumed an enemy stronger than him his size increased notably.

Rimuru has blue-silver hair in this form. There are no proper gender features, but he is mistaken for a young girl as his original form belonged to Shizue Izawa. He uses his anti-magic to keep this memento from Shizue and his pattern of speaking is like a prepubescent boy.

His hair resembles that of his original slime body, his human form and his slime body is equal in mass so Rimuru fills his body with solid shape instead of black fog. As he is not using the black fog he doesn’t require additional magic to maintain the form and there is no discomfort when he is in this form. His human form increases drastically when he is in his human form and he finds it easier to navigate around. This form is human but still, he doesn’t need to breathe or excrete, but he can eat, drink and taste freely.

He wears a black fur coat and a scarf in human form. Under that coat, he wears a kimono and pants made by Shuna. As an undergarment, he wears steel thread underwear that he made for himself, and to hide the monstrous aura he wears Shizue’s old mask.

After becoming a Demon Slime he is seen wearing a black overcoat. His fingernails have become sharper and his overall look is slightly older.


Rimuru Tempest Personality

Rimuru has a peculiar personality and a thoughtful heart. He always tries to avoid troubling situations as much as possible and he works very efficiently if there is a task to be taken care of.

As he was a hard-working salaryman and a cherished senior co-worker, Rimuru always helps anyone in need which often increases his workload.

Rimuru tends to react severely in conditions where his close ones are in danger such as his subordinates, countrymen (as his and their souls are linked) students, and good friends (as he cannot see children suffering). It can be said that he overreacts but it can be seen that he truly cares about them. 

He doesn’t shy back from destroying his enemies regardless of their numbers, who try to harm his subordinate and his country.

If a mishappening to his subsidies he quickly reverts back to his laid self and scratches his head at the scenery that he caused. 

Other demon lords describe him as cautious and cunning as they don’t know that he tries to avoid getting into troubling situations. As the story progresses he actually becomes a true demon lord and he bends the rules of the new world. He also understands the capabilities of his subordinates and allows them to handle tough situations by themselves.
