A single slime reincarnated in another world after being stabbed by a random attacker. His name in his previous life was Satoru Mikami. He was a salaryman working for a major general contractor, but he died from a fatal wound sustained while shielding a junior colleague who was being attacked during a meeting to introduce the colleague's fiancé. His personality is generally gentle and virtuous. According to Veldora, his best friend and the one who named him, "Rimuru is basically serious, sincere, and hates lies, but in battles he cannot afford to lose, he will calmly execute any underhanded tactic necessary." He is the type to act as soon as he has an idea, incorporating events and food culture he experienced in Japan into the Jura Tempest Federation to promote the development of entertainment and culture. Since his past life as a human, he has been prone to taking on too much, and despite complaining, his caring nature makes him beloved by his subordinates and juniors. Originally a peaceful pacifist like a typical former Japanese citizen, since his awakening and evolution into a Demon Lord, he has also acquired the ruthlessness befitting a leader of a nation, viewing anyone who obstructs his ideals or goals as an enemy to be cut down (it could also be said he has learned to effectively utilize his hidden lonely side). Having spent a long time in the Jura Tempest Federation since reincarnating as a slime, his personality and values have shifted from "human" to a "monster friendly to humans." Because of his position as a low-level monster slime, many people look down on him. Even after becoming a Demon Lord, he is viewed with caution but often suffers from fatal misevaluations as "just a newcomer" or "a slime just riding on Veldora's coattails," leading to complete defeats for powerful characters who initially opposed him based on those assumptions. From Rimuru's perspective, since those who underestimate him and force unreasonable demands are essentially trying to take (his friends) away from him, he naturally shifts into a pattern of resisting and overcoming them with his full potential, making him paradoxically a bad match for such opponents. Because he lacks blood vessels and nerves, he does not bleed, cry, or feel pain. Since he doesn't need oxygen, he doesn't breathe, and since he has no metabolism, he doesn't get hungry. All his cells function as brain cells, nerves, and muscles, and the computational cells used for thinking take turns resting, so he does not need sleep. He has a gender-neutral appearance that can look like either a lovely beautiful girl or a youthful beautiful boy, characterized by long bluish-silver hair and golden eyes (*his hair is technically closer to the transparent/light blue of a slime). His appearance is so beautiful, by his own admission and others', that he still occasionally finds himself staring at his own reflection in a mirror. Perhaps because it has been a while since he became able to mimic a human form, his gestures have recently become cuter, as if influenced by his appearance. Voice: Sounds like a young girl or a boy before his voice breaks; the gap created by his slightly middle-aged man way of speaking from his past life enhances his cuteness. First person: I (casual, masculine) Second person: you (blunt) Gender is genderless.
