Background / History

Mai first enters Shuya Inoue’s orbit as a candidate for a children’s-clothing advertisement. Her beauty immediately stands out to him, and their first meeting becomes the start of a lasting connection 10 12. Although visibly nervous during the shoot, she hides her trembling hands and remains composed; Shuya recognizes her mental fortitude and teaches her advertising poses after they exchange phone numbers 12.

At six, Mai is already mature, self-assured, and highly ambitious. Shuya’s abilities motivate her to work harder and surpass him rather than merely admire him 13. Her early career also isolates her: frequent acting lessons and training cause her to miss school, leaving Shuya as her primary companion. After a month of regular outings and nightly calls, the two become best friends 25.

Shuya recommends Mai for the Morning Drama role of Asagami Miin and introduces her to established industry figures. Her perceptiveness, natural acting, and willingness to learn allow her to adapt quickly; directors and producers regard her as a major find 129. Her performance rapidly makes her famous throughout Japan, earning her several exaggerated public nicknames 133.

Mai later falls out with her mother, moves into her own Fujisawa apartment, and becomes more independent. She and Shuya had both temporarily withdrawn from the entertainment industry two years earlier, though Mai’s hiatus is described as more complete than his 283. She subsequently returns to public work, joins Hanazawa Agency, and resumes acting, commercial, and idol-related activities 360 441 568.

Appearance

Mai is renowned as an exceptional beauty from childhood and is later described as a national-level beautiful girl whose looks continued to improve as she grew older 10 283.

• Long, straight black hair 10 12
• A composed, mature aura that makes her the center of attention even among other attractive girls 300
• A striking figure, long legs, and an “impressive bust” noted during her bunny-girl appearance 342
• Can adopt a convincingly cute idol image despite normally projecting a more mature impression 568 569

Personality

Mai presents herself as poised, well-mannered, and professional in public. Even as a child, she can converse confidently with adults, treat industry seniors respectfully, and manage attention without neglecting anyone 12 584. She is also proud of her appearance and abilities, bluntly answering “I know” when Shuya calls her beautiful 12.

Behind that polished exterior, Mai is sensitive and delicate. Her mature behavior began partly as a mask suited to her career, while work and school isolation leave her lonely and overwhelmed at times 25 29. She nevertheless loves acting and refuses to regret the path she chose 29.

Around people she trusts, Mai is mischievous, competitive, and teasing. She enjoys provoking Yukino with staged confessions and flirtatious banter, yet their friendship also brings out a carefree, childlike side of her 512 514 515. Her humor is often sharp, particularly when responding to Shuya’s behavior, but she remains capable of gratitude and recognizes the help he gave her at the beginning of her career 129 515.

Story Role / Major Arcs

Morning Drama

Mai plays Asagami Miin opposite Shuya’s Ikeda Ichinosuke. Their off-screen familiarity helps establish their on-screen partnership, while Mai’s performance turns her into a widely recognized child actress 129 130 133.

Puberty Syndrome

Mai’s crisis begins when she discovers that people can no longer see her, even while she is dressed conspicuously in public 342. The condition escalates into widespread memory loss: classmates, teachers, Shuya’s monster subordinates, and eventually even close friends begin forgetting her 343 341 353.

Shuya and Yukino investigate the phenomenon, consult Futaba Rio’s theory of observation, seek divine and institutional assistance, and learn that the incident is classified as Puberty Syndrome 348 349 350. Mai’s ordeal ultimately leaves her with substantially increased Power of Will and a new invisibility talent 364.

Return to Entertainment

After joining Hanazawa Agency, Mai faces renewed public scrutiny but handles a press conference alongside Shuya with calm professionalism 360. She later resumes commercial work, accepts a role in the drama Idol!, and rehearses for an idol performance 441 444 568.

Developing Feelings

Mai gradually acknowledges that Shuya’s early kindness, career support, and her mother’s attempts to separate them shaped her feelings for him 515. Shuya later confesses through a spectacular display of Power of Faith; Mai responds affectionately but postpones dating him because of the unresolved situation involving the Quintuplets 530.
