Description
Mimimi Utsukushisugi is the tenth girlfriend to enter into a relationship with Rentarou Aijo. She is a 16 or 17-year-old second-year student at Ohanamitsu University Affiliated High School, making her an upperclassman to Rentarou. Physically, she is a notably tall young woman with long, flowing blonde hair and narrow teal eyes with long eyelashes. Her forehead is particularly prominent.

Her name is a direct reflection of her character, as it incorporates the kanji for beauty multiple times and essentially means extremely beautiful. The repetition of the syllables mi also phonetically resembles the English phrase me, me, me, which aligns with her outwardly self-focused personality.

Mimimi possesses a very haughty and narcissistic personality, constantly praising her own beauty and expressing her self-love. She has absolute confidence in her appearance and a powerful sense of self-affirmation. She is so proud of her looks that she initially decides to give Rentarou a makeover, believing he needs to be more beautiful to be worthy of dating her. Her speech often has an ojou-sama or young lady quality, using phrases like desuwa, which she studied and adopted on her own to enhance her elegant aura.

Despite this seemingly superficial obsession, her motivation for beauty is rooted in a deep-seated philosophy of hard work and self-improvement. She is not a naturally flawless rich girl but rather someone who has built her beauty through relentless effort. Mimimi works a job delivering newspapers to earn money for expensive cosmetics and clothing, and she is frugal in other areas of her life to afford them. She has studied makeup, skincare, and even her manner of speaking to craft her beautiful image, firmly believing that beauty is not something one is born with but something one creates. This dedication extends to her physical fitness, as her delivery job has also made her exceptionally fast and agile.

While she is competitive, especially with those she considers her equal, she is also surprisingly gracious and able to recognize beauty in others. Her primary rival is Eiai Nano, whom she admits surpasses her in beauty. This admiration and rivalry stems from a past incident in junior high when Mimimi, after losing to Nano in a beauty contest, tried to befriend her only to be coldly rejected. This rejection festered into resentment, and when they reunite after Mimimi starts dating Rentarou, she challenges Nano to a competition where the loser must leave Rentarou's family. The conflict ultimately resolves when Nano apologizes, and they are able to become true friends. Beyond this, she values inner beauty as well; she was genuinely moved by Rentarou's kind and selfless actions, which made her recognize the beauty of his heart.

In the story, she serves as one of the many girlfriends in Rentarou's large family. Despite her narcissism, she is often one of the more level-headed and common-sense members of the group, sometimes taking on an elder sister-like role. Her key relationships include her close bond with Nano after their reconciliation, and a significant dynamic with Meme Kakure, a shy girl who hides her face. Mimimi helps Meme gain confidence and is deeply impressed by Meme's hidden beauty, often begging to know her secrets.

Mimimi shows some development as she becomes more integrated into the family. Her initial fear of rejection and her prickly pride soften as she forms genuine friendships with the other girlfriends, particularly Nano. Her love for Rentarou is demonstrated in her actions, such as when she refuses to perform a kissing scene in a school play, not because she dislikes kissing Rentarou, but because she wants their real first kiss to be special and not part of an act.

Her notable abilities include her incredible running speed and agility, honed from her newspaper delivery job. She is also an expert in all matters of beauty, from cosmetics and fashion to nutrition and skincare, and can enhance the beauty of others. Her beauty itself is portrayed as almost supernatural, capable of reflecting sunlight from her forehead and dazzling those who look at her. This ability to attract attention is so potent that she can use it as a tactical distraction, a technique she has perfected with Meme.
