Description
Mion Takamine is a Prism Star affiliated with Pretty Top and a core member of the idol group MARs. She possesses blonde hair, blue eyes, and a light complexion. Her hairstyle evolved from short, slightly wavy hair in *Aurora Dream* to a longer, stylized look accessorized with a headband in *Dear My Future*. Her fashion consistently features cool-style clothing in dark colors, documented through numerous specific coords across both series, including the "Ribbon Cool T-Shirt" for casual wear in *Aurora Dream* and the "MARs Shiny Purple Skirt" for group performances in *Dear My Future*.

Born on March 3, 1997, in Buenos Aires, Argentina, Mion moved to Tokyo, Japan, living alone due to her parents' frequent business trips. This isolation fostered a guarded personality, often leading her to mask emotions with a cold or manipulative exterior. She initially dismissed Prism Shows and refused collaboration until witnessing Aira Harune and Rizumu Amamiya's debut performance. Her entry into Pretty Top was dramatic, striding onstage to interrupt Aira's Tiara Cup victory with a solo showcase that asserted her superior skills. Assigned to form a duo with either Aira or Rizumu for the Summer Queen Cup, Mion tested both before selflessly withdrawing, recognizing their potent synergy as a pair.

Mion's emotional barriers started crumbling after MARs' Summer Queen Cup loss, where she broke down in tears acknowledging her powerlessness – her first display of vulnerability. She gradually bonded with Aira and Rizumu, exemplified when she abandoned a high-society dinner to join their sleepover, bringing macaroons and participating in heartfelt conversations, even admitting her crush on the adult Jun Takigawa. Her relationships evolved significantly: she developed respect for Aira's fashion talent despite initial blunt critiques, while her dynamic with Rizumu shifted from intentionally provoking arguments to mutual respect. Her romantic admiration for Jun waned over time, and interactions with Wataru, who openly admired her, became more playful and reciprocal.

In *Dear My Future*, set three years later, the 18–19 year old Mion rejoined MARs after Aira became Prism Queen. She expanded her career into acting, starring in the TV show "Magical Mion," and mentored newer idols like Prizmmy through vocal coaching. During the "Road to Symphonia" tournament, MARs was coerced into joining the Symphonia Syndicate following Aira's manipulation, forcing them to defeat rival groups under duress. They were freed when Puretty broke the Syndicate's control. Mion supported Rizumu during her marriage to Hibiki and defended Pretty Top's founder, Kyoko, against bribery allegations, though these were proven true. A vision of her future depicts her as Pretty Top's president, guiding new Prism Stars with Wataru's assistance.
