Mimete serves as the second member of the Witches 5, operating under the Death Busters organization. She holds the lowest rank within the group at Level 40. Her civilian identity is Mimi Hanyu, a performing arts instructor at Mugen Academy who simultaneously pursues a career as a teen idol singer. This alias allows her to host concerts exclusively for students, like one celebrating the opening of the Mugen Academy Memorial Dome. Physically, she possesses short, wavy orange hair and lighter skin. Her attire features a black bra connected to a skirt adorned with orange stars and a black diamond. She wears a black necklace with a star pendant, an orange bracelet, orange underskirts, and yellow tights. Accessories include a pearl tiara with lilac gems and matching earrings. Her footwear consists of black sandals with diamond accents and white leg straps. Mimete's primary abilities center on charm-based magic. She employs her "Charm Buster" attack, projecting star-shaped sound waves or energy projectiles from her staff. Performing as Mimi Hanyu, she places concert audiences into trances to harvest their souls using a projected black star. She can summon and implant Daimon Eggs into humans, transforming them into Daimon monsters. Additional capabilities include floating in mid-air and executing rapid outfit changes. Her narrative arc begins when Kaolinite assigns the Witches 5 to eliminate the Sailor Guardians. Following Eudial's demise, Mimete assumes responsibility for soul collection. Using her idol persona, she lures fans into traps to steal their souls, an effort thwarted by Sailor Venus. Mimete retaliates by creating Daimons from three individuals, though the Sailor Guardians defeat them. During a confrontation, she directs a potent energy blast at Sailor Chibi Moon. This attack is countered jointly by Sailor Neptune’s "Deep Submerge" and Sailor Uranus’s "World Shaking," resulting in Mimete’s destruction. Kaolinite briefly resurrects Mimete and the other witches. Resurrected, Mimete isolates Sailor Venus, exploiting Minako Aino’s idol aspirations by coercing her into singing. This psychological manipulation causes Minako to question her commitment as a Sailor Guardian. The Outer Guardians intervene, and Sailor Neptune’s "Submarine Reflection" destroys Mimete and the Witches 5 permanently. Mimete exhibits a narcissistic and attention-seeking personality, prioritizing fame and personal desires over her duties. She relishes using magic and adopts a manipulative, seductive demeanor to achieve goals. Her fixation on celebrities often interferes with missions, and she displays cruelty toward rivals like Eudial. Her voice is described as "bimbo-like," aligning with her idol persona. She shares a specific rivalry with Sailor Venus, stemming from their conflicting ambitions—Mimete’s pursuit of idol stardom versus Minako’s dedication to guarding. This dynamic culminates in Mimete exploiting Minako’s doubts during their encounter in Act 34. Her name derives from mimetite, a yellow-orange mineral, reflecting her color scheme and thematic association with imitation through her alias.
