Ramiris ranks among the first-generation Demon Lords alongside Guy Crimson and Milim Nava, holding the third seat on the Octagram council. Originating millennia ago as ruler of the Elementals, her status solidified during a pivotal event where she intervened to halt the destructive rampage of the newly awakened True Demon Lord Milim Nava. This intervention caused her to absorb a fusion of evil Daemon magic and potent dragon aura, corrupting her into a unique Elemental and establishing her place within the original trio of Demon Lords who divided their roles: one seeking the Ultimate Skill, one living freely, and one judging the world.
She manifests in two distinct forms. Her frequently seen pixie form presents as a small, flat-chested fairy with golden eyes, blonde pigtails, and wings, often mistaken for an ordinary pixie due to her minimal presence. In stark contrast lies her true mature form, remembered by Veldora, as a beautiful woman—a state she rarely assumes.
Her personality blends a free-spirited, often oblivious nature with an impulsive streak, disregarding others' opinions and lacking typical Demon Lord dignity. She exhibits smugness regarding her dual status as Elemental Queen and Demon Lord. Underneath lies genuine kindness, prompting her to willingly aid those in true need. She reacts intensely to insults or underestimation, frequently throwing tantrums when mocked. Easily bribed with sweets due to her small size, she occasionally struggles with verbal communication after prolonged telepathy use, sometimes biting her tongue.
Her core power is labyrinth creation via the authority "Small World," generating isolated multidimensional spaces vastly larger inside than out. These labyrinths hold up to 100 customizable floors, restrict telepathy, and feature resurrection mechanics for wearers of special items. Maintenance requires external magicule sources, like Veldora's constant energy emissions, which can cause uncontrolled phenomena such as dense dryad forests. Additional powers include primitive magic to alter world laws, annihilation magic delivering instant death via black light, multiple layered barriers, and enhanced perception accelerating thought processing millions of times. As an ultimate skill user, she resists lower-tier abilities including magic, mind manipulation, spatial distortion, and existence erasure.
Her adult form dramatically expands capabilities to universe-level destructive potential, faster-than-light speed, and mid-godly regeneration—repairing body, mind, and soul if her core remains intact. This state also grants abstract existence as a spiritual life form, intangibility, and advanced information analysis. Maintaining it, however, is limited to single battles before reversion.
Key relationships define her: she mentors chosen heroes by bestowing divine protection, partners with Rimuru Tempest to manage the labyrinth in Tempest, and shares millennia-old ties with fellow Demon Lords Guy and Milim. Her subordinates include Beretta and Treyni, both granted physical forms by Rimuru.
Historically, Leon Cromwell defeated her before his own Demon Lord ascension when her spiritual manipulation backfired. She later aided his research into summoning otherworlders, concluding targeting specific individuals was impossible. She repurposed discarded elemental magic circuits from failed dwarf-elf projects to enhance her golems.
Her current responsibilities involve preserving world balance and overseeing labyrinth operations, often collaborating with Tempest's leadership. Despite her stature, she remains unaware of her negligible presence and continues acting as a self-proclaimed guardian of equilibrium.
