Description
Mimimi Utsukushisugi is the tenth girlfriend of Rentarou Aijou in 100 Girlfriends Who Really, Really, Really, Really, Really Love You. She is a second-year student at Ohananomitsu High School, attending class 2-2, and is a graduate of Mirei Middle School, where she was a classmate of Eiai Nano. Her birthday is March 3. She is tall with long, flowing blonde hair that was slightly adjusted toward a platinum tone for the rebroadcast of the first season, narrow teal eyes with long lashes, and a slender figure that others frequently take notice of.

Mimimi carries herself with extreme self-confidence and narcissism, constantly speaking about her own beauty and interpreting nearly any remark directed at her as a compliment. Her typical reaction to perceived praise is a smug, pleased demeanor accompanied by her signature lighthearted attitude, which even Rentarou has described as more cute than beautiful. Despite her vanity, she does care about dimensions of beauty that go beyond the surface. She recognizes inner beauty when she encounters it, and she becomes interested in Rentarou largely because she sees something beautiful in his character that she wants to help refine. She initially takes it upon herself to make Rentarou more outwardly beautiful, but her appreciation for him deepens over time.

Her motivation is rooted in a genuine obsession with beauty itself. She works hard to maintain her appearance, contrary to the assumption that she is simply a naturally beautiful rich girl. She earns her own money, is frugal when necessary, and invests significant effort into grooming and clothing in order to achieve the look she wants. She is competitive, especially with Eiai Nano, whom she acknowledges as superior to her in certain respects, and she does not shy away from rivalry over looks or status. At the same time, she has a strong independent streak and supports herself financially.

Within the story, Mimimi was introduced as one of the chaotic upperclassmen alongside Kusuri Yakuzen, and her antics initially bewildered the other characters. As the girlfriend cast grew larger and more eccentric, she gradually shifted into a role closer to a semi-straight person, often delivering polite and commonsense commentary in a composed, elegant manner while still maintaining her self-adoring demeanor. She is the second senior heroine of the series, after Kusuri.

Her key relationship is with Rentarou, whose inner goodness she learns to admire, and she becomes a devoted partner who wants to support him in return. She shares a significant history with Eiai Nano, having attended the same middle school, which adds both camaraderie and competitive tension to their interactions. With the rest of the Rentarou family, she remains graceful and occasionally bewildered by the chaos, but she fits into the group as someone who can both instigate and calm situations depending on the context.

In terms of development, Mimimi begins as a character defined almost entirely by surface-level vanity, but she gradually reveals a more complex personality. Her hardworking background, her ability to appreciate non-physical beauty, and her willingness to respect others' strengths all emerge as the narrative progresses. She retains her core narcissism as a comic trait, but it becomes tempered by genuine affection and loyalty toward her partner and the other girlfriends.

Her notable abilities include an extraordinary dedication to personal grooming and fashion, a keen eye for aesthetics, a strong work ethic that allows her to independently support her lifestyle, and the capacity to remain composed and speak with polite clarity even in absurd situations. She is also physically tall and naturally striking, which she leverages with full awareness. Her self-love, while exaggerated, gives her an unshakable confidence that does not waver even when she faces rivals or challenges.
