​Personality: Cold, sharp, practical, highly analytical, and maternal toward Milim (acting as a strict mother figure who forces Milim to do her homework and governance paperwork).
​Background Story: Ruled the Harpy nation of Fulbrozia. She was blackmailed by Clayman, who held an army of puppet parasites over her nation. She feigned compliance by backstabbing Carrion, but secretly worked to protect both Carrion and her own people. At Walpurgis, she helped reveal Clayman's scheme, stepped down as a Demon Lord due to her combat limitations compared to True Demon Lords, and took over the administrative rule of Milim's territory.

​Both Carrion and Frey were members of the "Ten Great Demon Lords." During the Walpurgis banquet, recognizing the overwhelming power difference between themselves and entities like Rimuru and Milim, they voluntarily abdicated their Demon Lord seats. They stepped down to become high commanders under Milim Nava's unified dragon kingdom.

When Milim Nava (under Clayman's brainwashing illusion) destroyed his capital, Carrion fought her one-on-one to draw the destruction away from his citizens.

   ​Background Story: In his pride, he was manipulated by Footman and Tear of the Moderate Harlequin Alliance into becoming the host body for the calamity monster Charybdis.

​3. Humanoid & Ancient Ancestral Races

​Elves & High Elves: Long-lived humanoids possessing acute affinity for spirit magic and high natural intelligence. High Elves (like Emperor Elmesia) are divine ancestors created directly by Twilight Valentine.
​Dwarves: Short, stocky, highly durable humanoids renowned for metalworking, magitech engineering, and weapon smithing. Their capital city-state is the Armed Nation of Dwargon.
​Giants: Ancient, massive humanoid beings descended from divine natural forces. Possessing extreme magic immunity and high physical density, they rule the western desert regions under Demon Lord Dagruel.
​Vampires: Immortal, blood-consuming spiritual-physical hybrids created by Twilight Valentine. They possess high longevity, natural charm abilities, and advanced holy/dark magic mastery, led by Demon Lord Luminas Valentine.

​2. Demi-Humans & Monster Races
​Goblins / Hobgoblins: Small, green-skinned, weak monsters living in tribal structures. Upon receiving names from Rimuru, males evolve into tall, muscular Hobgoblins, and females evolve into sleek, attractive Goblinas.
​Ogres / Kijin / Fair Oni: Horned humanoid warriors native to the Great Jura Forest. Known for physical strength and elemental affinity. Named Ogres evolve into Kijin (refined humanoids with small forehead horns) and can further evolve into Divine Oni or Spirit Oni.
​Orcs / High Orcs: Pig-like humanoids known for high physical stamina and labor capacity. Following the defeat of the Orc Disaster, Rimuru named the survivors, evolving them into High Orcs who serve as Tempest’s primary construction and heavy defense force.
​Lizardmen / Dragonewts: Amphibious reptilian humanoids dwelling in wetland environments. Upon receiving names, they evolve into Dragonewts—gaining dragon-like wings, retractable scales, enhanced magicule reserves, and the ability to alternate between full dragon and human forms.
​Direwolves / Star Wolves: Canine monster packs driven by hierarchy and alpha leadership. Under Ranga, their evolution progressed from Direwolves to Tempest Star Wolves, granting them black lightning manipulation and shadow-stepping capabilities.

1. Demonic & Spiritual Life-Forms
   ​Slimes: Viscous, non-cellular fluid organisms that do not require oxygen, food, or sleep to survive. They subsist entirely on ambient magicules, organic matter, and grass. While wild slimes are low-intelligence creatures, Rimuru evolved into a unique Demon Slime and ultimately an Ultimate Slime (Viscous Dragonoid Demon God)—a Fifth True Dragon equivalent.
   ​Demons (Akuma): Spiritual beings originating from the Underworld. They are divided into color lineages (Red, Black, White, Yellow, Purple, Blue, Green) led by the Primordials. Their evolutionary hierarchy spans: Lesser Demon → Greater Demon → Arch Demon → Demon Peer → Devil Lord.
   ​Angels (Tenshi): Beings of pure divine light created by Veldanava to maintain order. They lack individuality unless exposed to physical friction over centuries, which turns them into Fallen Angels or Phantoms.
   ​Phantoms & Cryptids: Transdimensional spiritual entities dwelling in foreign dimensions. Phantoms are corrupted/evolved Angels led by Feldway, while Cryptids are mindless, massive insectoid and beastial monsters born from wild energy.

Mechanics of Naming a Monster
​In the world of Tensura, naming a monster is a fundamental magicule-based process that alters the target's fundamental existence, soul strength, and evolutionary path.
​Soul Bond & Master-Servant Lineage: Naming creates a permanent spiritual corridor between the Namor (master) and the Namee (servant). The name acts as an anchor that stabilizes the monster’s soul and binds their identity.
​Evolution & Physical Reconstitution: When a monster receives a name, its soul density increases drastically, triggering an instantaneous or gradual biological evolution. Lower monsters often humanize or refine their physical structures (e.g., Goblins becoming Hobgoblins/Goblinas; Ogres becoming Kijin; Lizardmen becoming Dragonewts).
​Magicule Consumption & Risk: Naming consumes a massive amount of the namer's permanent magicule capacity. If a namer exhausts too many magicules, they risk a permanent drop in power, physical atrophy, or death. Rimuru bypassed this limitation because Great Sage / Raphael managed his magicule expenditure and safely borrowed excess magicules directly from Veldora Tempest's sealed reservoir.
​Naming via Family/Surname: Granting a shared family name (such as Rimuru granting the surname Tempest to Veldora) creates an equal-level soul lineage and mutual protection pact rather than a master-servant relationship, bestowing divine blessings (Divine Protection of the Storm) across an entire group or nation.

Tensura is the official shorthand name for That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken), a popular Japanese light novel series written by Fuse and illustrated by Mitz Vah. The series follows Satoru Mikami, a 37-year-old Japanese corporate worker who dies in Tokyo and is reborn in a high-fantasy magic world as a humble Slime. Taking the name Rimuru Tempest, he uses his unique cheat abilities—primarily Predator (later Beelzebuth) and Great Sage (later Raphael / Ciel)—to absorb powers, build a multi-species nation called the Jura-Tempest Federation, and eventually evolve into a True Demon Lord and a True Dragon-level entity.
