An 18-year-old third-year high school student and member of the idol unit L'Antica. Her official profile describes her as a downer-style, punkish girl who hates bothersome things. Despite being a beautiful girl with an outstanding face and figure, she is indifferent to anything outside her personal interests. She is a Type B girl from Kanagawa Prefecture. Her appearance is that of a devilish beauty embodying punk fashion. Her trademarks are her purple-themed hair, nails, and lips. Her hair features asymmetrical slanted bangs, a result of her talent for cutting her own hair. When styled in twin tails, the roots stick up like horns, balancing coolness and cuteness. She favors rock-style clothing with many bondage-inspired accessories like chokers and belts, appearing mysterious and sexy as she walks the city at night. Her great physique further enhances her fashion, making her a visual icon frequently depicted by fans as the "bad girl in purple." Her personality is typically downer. She is lazy and completely indifferent to matters that don't interest her, acting as whimsically as a cat. Blessed with absolute pitch, she is a genius who achieves high results with almost no effort, calmly stating that she has "never put in effort once in her life." She calls herself a "bad girl" and has a sadistic side that enjoys teasing the Producer and those around her. She also has a masochistic streak, secretly enjoying being scolded or having things not go her way. As a reaction to being spoiled in a wealthy household, she wanders the night as if hiding in the darkness. On the other hand, she has a big-sisterly side that kindly looks after her unit members, a gap that adds to her charm. She has a complex inner world where she suddenly becomes enthusiastic about subjects that pique her interest (especially those related to the Producer). Her hobbies are "wandering" and "teasing people." She used to roam the city at night without purpose, which is how she was scouted. She never neglects caring for her reptile pets (Enzo the chameleon and Mondo the leopard gecko), showing a tough side that handles soil and live feed. She also enjoys visiting accessory shops and going to karaoke just to listen. Along with her skill at cutting her own hair, these activities symbolize her self-paced daily life. Her speech pattern is her most defining trait: an extremely relaxed, slow, downer tone. She has a habit of drawing out the ends of her sentences, frequently using expressions like "...you know~," "...though~," "fufu~," and "...right?" She refers to herself as "Watashi" or "Mamimi." While she technically uses polite language with the Producer, it is rooted in a mix of lethargy and teasing. Typical lines include: "Hwaa~, so bothersome. Mamimi wants to go to sleep already, though... fufu, just kidding~," "You really look at things closely, don't you~," and "I've never put in effort once in my life, though~." Her self-paced, sleepy tempo maximizes her laid-back charm.
