Description
Mimi Usa, a fictional character in *Kodomo no Jikan*, is a 10-year-old student in class 3-1, later 4-1, at Futatsubashi Elementary School. Standing 148 cm tall and weighing 42 kg with measurements B80-W68-H78, her zodiac sign is Capricorn.

Quiet and shy, Mimi was initially misunderstood by classmates as aloof, leading to social isolation. Her outcast status ended during a physical education class when she grouped with Rin Kokonoe and Kuro Kagami, forming their close friendship. Despite being the tallest, most physically developed, and academically strongest of the trio, Mimi retains significant childhood innocence and naivety regarding adult and sexual matters, often resulting in confusion or embarrassment when faced with innuendo.

Her background involves significant familial challenges. Her protective father moved away for work, removing key emotional support. Mimi experiences neglectful abuse from her mother, who shows clear preference for Mimi's older brother and displays indifference or blame towards Mimi. Her mother dismissed Mimi's report of being approached by a molester as Mimi's own fault and refused to assist with purchasing her first bra, forcing Mimi to endure the physical and social discomfort alone. Her mother also suggested Mimi stop attending cram school, unlike her brother. This environment fuels Mimi's intense self-consciousness about her intelligence, height, lack of athleticism, and physical development, leading to emotional fragility and depression.

Mimi grapples with establishing self-identity and finding her voice. Her lack of assertiveness makes her vulnerable to bullying and teasing. Teacher Daisuke Aoki becomes a significant protective figure, striving to shield her innocence from her friends' influences and darker realities like harassment. He posed as her brother to enable her participation in a magazine photo shoot; her published photo went unrecognized, even by Kuro. This event represented a step towards greater confidence.

Romantically, Mimi developed a secret crush on Reiji Kokonoe, Rin's cousin, after falling for him at first sight. Reiji recognized his younger self in her and advised her against succumbing to anger and hatred, encouraging her to maintain hope for finding understanding and love. Prompted by Rin, Mimi tearfully confessed her feelings, receiving Rin's unexpected blessing. Despite her deep affection, Mimi observes Reiji's complex emotional attachment to Rin, raising concerns for her friend's well-being, especially after witnessing Rin in a vulnerable state before they shared a moment of non-sexual intimacy.

Her friendships with Rin and Kuro, alongside Aoki's support, provide crucial emotional sustenance. However, her defining characteristics continue to cause her discomfort, making her journey towards self-acceptance ongoing and fraught with challenges related to her visibility and perceived differences.
