Aira Harune debuted as a 14-year-old middle school student from Yokohama, characterized by notable clumsiness and frequent falls, traits shared with her protective father Hiroshi. Parental concerns stemming from a childhood ice-skating incident where her father caused her fall and exaggerated its severity led to restrictions on watching Prism Shows. Despite her physical awkwardness, she possessed a natural talent for fashion coordination and the unique ability to hear the "voices" of clothing, allowing her to intuitively create harmonious outfits. Her journey as a Prism Star began accidentally when Jun Takigawa scouted her during a shopping trip after witnessing her redesigning store mannequins. Thrust into her first Prism Show alongside Rizumu Amamiya with no prior performance experience, she performed the "Fresh Fruits Basket" Prism Jump guided by her connection to her outfit's "voice." This marked the start of her affiliation with the Pretty Top agency and her eventual formation of the unit MARs with Rizumu and Mion Takamine. Rigorous training saw her overcome her clumsiness, growing in confidence and skill across competitions like the Tiara Cup, Summer Queen Cup, and Crystal High Heel Cup. Key jumps she mastered included "Lovely Rainbow," "Heartful Splash," and team jumps like "MARs Phoenix." A central aspect of her character was her selflessness. During the Tiara Cup finals against Rizumu, she forfeited her competition outfit to Rizumu after their Prism Stones were stolen, opting to perform in everyday clothes to demonstrate authenticity, which ultimately won her the Pure Crystal Tiara. Her motivations evolved from initially seeking approval from her father and idolizing Shou for his designs at Prism Stone to prioritizing her friendships with Rizumu and Mion. She achieved the legendary "Aurora Rising Dream" jump at the Prism Queen Cup, symbolizing the culmination of collective dreams. In later years, as depicted in *Dear My Future*, she transitioned from performing at age 18 to become a fashion designer for Prism Stone, channeling her innate understanding of clothing into creating outfits for new Prism Stars. Her role in *All Star Selection: Prism Show Best Ten* involved mentoring Lala, a new Prism Show student, sharing her experiences and insights to guide the next generation, highlighting her continued dedication to helping others discover their potential through Prism Shows.
