Human Form

Rimuru's facial features in human form are nearly identical to those of Shizu, but the long silver-blue hair and deep golden eyes give off an otherworldly divine beauty that sets the two apart. Rimuru can also occasionally be seen wearing Shizu's mask or donning draconic wings.

Rimuru's human form is that of an androgynous albeit girly 18 to 19 year old adolescent. The main outfit from this point consists of black pants and a black sleeveless long shirt accented with white boots and white stripes respectively. The arms have black detached long sleeves with golden ornaments at the top as well as a golden collar piece around the neck. The white rope-like belt has a metal loop at the back for the purpose of tying the scabbard of a sword. They can also occasionally be seen wearing a cloak over top of this outfit.

Additionally, Rimuru has been seen wearing a more casual version of this outfit with a more simple pair of overly baggy black pants and a white shirt.

Rimuru Tempest was originally a Japanese man named Satoru Mikami. After being killed during a robbery, he found himself reincarnated in a fantasy world as a slime monster.

Initially weak, he quickly acquired powerful abilities like "Predator," which allowed him to assimilate the skills of anything he consumed, and "Great Sage," an inner voice that acted as a guide and analyst. His first major step was befriending the Storm Dragon Veldora, who granted him the name "Rimuru Tempest."

Over time, he founded the Jura Tempest Federation, a nation for monsters, where he formed alliances with various races, including goblins, direwolves, ogres, and lizardmen. His goal was to create a place where monsters and other creatures could live in peace.

The turning point in his story was the human attack on his village. To avenge his friends and resurrect them, Rimuru evolved into a true Demon Lord, a process that gave him immense power and made him one of the strongest beings in the world. From that moment on, he acted not only as the leader of his nation but also as a prominent political and military player.
