Main characters

Rimuru Tempest (リムル・テンペスト, Rimuru Tenpesuto)

Voiced by: Miho Okasaki (Rimuru), Takuma Terashima (Satoru) (Japanese); Brittney Karbowski (Rimuru), Jason Liebrecht (Satoru) (English)

Rimuru Tempest's background story begins in Japan, where he was originally a human named Satoru Mikami. One day, while meeting a colleague from work, he is stabbed and killed by a criminal. However, he is reincarnated into a fantasy world called the Central World as a slime monster with unique abilities compared to the most Otherworlders, who were instead brought into the Central World. He is genderless, being considered as both a male and a female. As a slime, Rimuru initially struggles to survive in this new world, but soon discovers that he has the power to absorb and mimic the abilities of any creature he consumes, eventually gaining an androgynous human form that resembles a younger version of Shizue Izawa. This allows him to gain new skills and become stronger. Rimuru eventually meets and befriends different monster races quickly gaining a reputation as a powerful and benevolent leader who strives to build a peaceful society for all races. He then establishes a nation called Jura Tempest Federation and becomes its ruler, promoting equality and justice among all its inhabitants. He also forms alliances with other powerful beings, including the Demon Lord Milim Nava, "The Destroyer", and the Storm Dragon, Veldora Tempest. Throughout his journey, Rimuru learns about the politics, conflicts of the fantasy world, and becomes a respected leader who is known for his wisdom, kindness, high intelligence, and strategic thinking. Despite facing many challenges and enemies, Rimuru remains determined to protect his friends and allies while achieving his goals. He eventually evolves into a Demon Lord and becomes a member of the Octagram after defeating rogue Demon Lord Clayman. He owns the center region of the Magic Continent.

Great Sage (大賢者, Dai-kenja) / Raphael (智慧之王（ラファエル）, Rafaeru)

Voiced by: Megumi Toyoguchi (Japanese); Mallorie Rodak (English)

Great Sage is one of Rimuru Tempest's most powerful abilities in the series. It is a "Unique Skill," which means it is a unique ability that Rimuru gained when he was first reincarnated as a slime. Great Sage is a type of artificial intelligence that exists within Rimuru's mind, and it serves as his personal advisor and assistant. Whenever Rimuru faces a problem or needs information, Great Sage is able to analyze the situation and provide suggestions and solutions. It has vast knowledge and expertise in various fields, including science, magic, history, and more. It also has the ability to communicate with Rimuru through telepathy, making it a valuable tool for him. This feature was possible because of a partition of the voice from "Words of the World", also known as "Voice of the World", upon Rimuru's reincarnation to help him. Great Sage's intelligence and analytical abilities are almost unparalleled, and it is able to perform complex calculations and simulations in seconds. It also has a vast database of information, which it can access at any time to provide Rimuru with the answers he needs. In addition, Great Sage has a wide range of other abilities, such as being able to manage Rimuru's skills and abilities, predict future events, and provide suggestions for strategic planning. After Rimuru became a Demon Lord, Great Sage evolves into Raphael.

Veldora Tempest (ヴェルドラ, Berudora)

Voiced by: Tomoaki Maeno (Japanese); Chris Rager (English)

One of the four original True Dragons, the "Storm Dragon", Veldora is a powerful dragon classified as a "Catastrophe-level" threat who was sealed away by a "Hero" in a cave for 300 years. When Veldora meets Rimuru, he was impressed by Rimuru's intelligence and confidence, especially being that he was a slime one of the lowest if not the lowest of the monster races the two then formed a strong bond giving each other names. Veldora then teaches him about the world and helps him to improve his skills and abilities. In turn, Rimuru helped Veldora by providing him with companionship and freeing him from the "Infinite Prison" by devouring him. He is soon released and given a human body. He also agreed to serve as a front for the defeat of Falmuth's army. Throughout the series, Rimuru and Veldora work together to achieve their goals and protect their friends. Veldora also provides Rimuru with valuable advice and assistance, using his immense power to aid him in battles against powerful enemies. Their relationship is a testament to the power of friendship and loyalty, and their bond remains strong even when they are separated for prolonged periods of time. Overall, Rimuru and Veldora's relationship is one of the major highlights of the series. He is also revealed to be the uncle of the Demon Lord Milim Nava. He later moves into the Dungeon, where he serves as its master.

Gobta (ゴブタ, Gobuta)

Voiced by: Asuna Tomari (Japanese); Ryan Reynolds (English)

Gobta is a small hobgoblin who serves Rimuru as the leader of goblin riders. Despite how younger, smaller, and dumber he looks than other hobgoblins, he unexpectedly holds great proficiency in sword-skills enough to take down a big monster. Hakuro noted Gobta has talent worth nurturing. He ends up being a comedy relief, but nevertheless a competent fighter, not only as a swordsman, but as a magic user as well.

Rigurd (リグルド, Rigurudo)

Voiced by: Kanehira Yamamoto (Japanese); Kent Williams (English)

Rigurd is the sub-leader of the goblins in Tempest. Rigurd tends to be the comic relief due to his loyalty to Rimuru making him act silly at times.

After defeat of the Orc Lord, he and the other ogres permanently swear their allegiance to Rimuru and are named; resulting in their evolution into Kijin, a rare type of ogre. Later, after pledging eternal allegiance to Rimiru, he was given the title of "Samurai General". He becomes immensely powerful after Rimuru becomes a Demon Lord, causing him to evolve into an Oni.
