Elena Amamiya, Cure Soleil, is a third-year middle school student celebrated as "The Sun of Mihoshi Town" for her vibrant energy and athletic prowess. Balancing school life with part-time work at her family’s Sonrisa Flower Shop, she manages responsibilities while caring for her six younger siblings. Her Mexican-Japanese heritage grants fluency in English and Spanish, though childhood insecurities about her darker complexion once made her feel isolated—a struggle she overcame by embracing her individuality.

Transforming via the Star Color Pendant and Pen, Cure Soleil dons a fiery orange-and-yellow ensemble with a star-patterned headband, a tiered dress, and sturdy boots. Specializing in agile combat, she unleashes scorching kicks and signature attacks like the Soleil Shoot and its enhanced Libra iteration, frequently uniting with allies for coordinated strikes such as the Southern Cross Shot.

In *Hoshi no Uta ni Omoi wo Komete*, she defends the celestial being UMA against extraterrestrial threats. Separation from UMA tests her resilience, catalyzing her growth from championing personal joy to safeguarding collective peace. A climactic alliance with teammates sees her channel Miracle Light to stabilize UMA, underscoring her matured perspective on unity.

Behind her bold persona lies a dislike of horror films and a whimsical stint as the "Solar Prince" during a school festival. Post-graduation, she pursues TV interpretation for space-related broadcasts, reflecting her commitment to cross-cultural connections.

Notable traits include a beauty mark beneath her left eye, distinguishing her as the franchise’s first dark-skinned main Cure with this feature. Born September 8 under Virgo, her journey mirrors her astrological sign’s dedication to service and growth.
