Description
Rimuru Tempest began life as Satoru Mikami, a 37-year-old Japanese salaryman reborn as a slime after perishing protecting a colleague. Awakening in a fantasy world, Rimuru gained unique abilities to devour and mimic other beings. A pivotal bond formed with the sealed Storm Dragon Veldora; they exchanged names, with Rimuru promising freedom. This act named Rimuru Tempest and granted Veldora the surname Tempest. Rimuru later absorbed Veldora temporarily to analyze the sealing magic, marking the start of their shared journey.
Rimuru's natural form is a spherical or amorphous mass of translucent blue ooze, initially 40 cm in diameter, growing to roughly 80 cm after evolving into an Ultimate Slime. This form can adopt metallic or golden appearances, such as when using the Body Armor skill or evolving into a Demon Slime. By absorbing the deceased human Shizue Izawa, Rimuru gained a permanent humanoid form. This form evolved: starting as a child resembling age six or seven, progressing to nine after consuming the Orc Disaster, then to twelve or thirteen upon becoming a True Demon Lord, finally stabilizing as an androgynous adolescent resembling age fifteen or sixteen with silver-blue hair and golden eyes. Clothing varied, incorporating elements like a fur scarf, haori, or casual attire, reflecting stages of power and leadership. Rimuru is genderless, a creator decision, though Rimuru often uses male pronouns mentally due to Satoru Mikami's past life.
Rimuru's personality blends Satoru Mikami's human experiences with monster instincts. Appearing kind-hearted, diplomatic, and peace-loving, Rimuru often prioritizes negotiation over conflict and struggles to refuse requests for help—a trait carried over from corporate life. Underneath lies a shrewd, analytical mind capable of strategic planning and manipulation, including rewriting history or erasing memories to maintain a benevolent image. While generally easygoing and dedicated to creating a comfortable world, Rimuru exhibits ruthless pragmatism when enraged, resorting to intimidation, blackmail, or lethal force against threats to loved ones or Tempest. Leadership anxieties and self-doubt persist, sometimes leading Rimuru to agree to unfavorable diplomatic terms, though guidance from allies like King Gazel Dwargo fostered greater self-assurance.
Rimuru founded and rules the Jura Tempest Federation, starting as a village for goblins and direwolves before expanding into a nation for diverse monsters. Leadership stems from overwhelming power and a vision of coexistence, attracting allies like dwarves, lizardmen, and ogres—whom Rimuru named, causing their evolution into stronger forms such as Kijin. Naming creates a soul-level lineage, inadvertently granting power boosts to all named subordinates during Rimuru's ascension to True Demon Lord. The nation's growth drew attention from foreign powers, including human kingdoms and demon lords, necessitating complex political maneuvering.
In "The Slime Diaries," set during Tempest's peaceful development, Rimuru engages in slice-of-life activities. These include attempting to document adventures in a diary, participating in town meetings, handling paperwork (often humorously disrupted by subordinates like Shion), and introducing Japanese cultural practices. Rimuru oversees seasonal events and festivals, coordinating outfits for celebrations—including dresses chosen communally—and sharing traditions like cherry blossom viewing. Daily routines involve interacting with citizens, from patrolling with Benimaru to observing Goblin Riders or visiting craftsmen like Geld, highlighting Rimuru's role as an approachable leader invested in community wellbeing. These activities reinforce Tempest's unity and reveal Rimuru's lighter, whimsical side.
