Description
Yuna Hijirisawa, a second-year student from Kozu-shima, co-founded the school idol unit Sunny Passion with Mao Hiiragi to combat their island's population decline by boosting its profile through idol activities. Sunny Passion secured early prominence by winning the Love Live Tokyo regionals before Liella!'s formation and advancing to the tournament finals, an achievement that motivated Keke Tang to become a school idol in Japan.

She sports yellow-orange shoulder-length hair usually tied in a ponytail and green eyes. Her demeanor radiates cheerful, talkative energy, often revealing sharp teeth during broad smiles, blending warm friendliness with competitive spirit.

In Sunny Passion, Yuna embodies the "Sun" persona against Mao's "Sexy Night," with passion orange as their signature color. Their performances, including the debut song "HOT PASSION!!," prioritize high-energy vibrancy. Despite rivaling Liella!, Yuna supports its members—especially Kanon Shibuya—and publicly credited Liella!'s emotional influence during Sunny Passion’s Love Live victory interview, amplifying Liella!'s recognition.

As a mentor, she invited Liella! to Kozu-shima for a joint summer concert, co-building the stage with locals. There, she advised Kanon that loving to sing justifies being a school idol, stressing intrinsic motivation over external validation. She also critiqued Liella!'s over-reliance on Chisato Arashi’s choreography, urging individual enthusiasm and artistic autonomy for growth.

Yuna approaches rivalry as self-improvement fuel. After Sunny Passion’s unexpected Tokyo regionals loss to Wien Margarete—which she attributed partly to complacency despite full effort—she accepted defeat gracefully. Later, she and Mao explained to Kanon that competitions like Love Live push idols beyond solitary enjoyment, framing victory as collective advancement over mere rivalry.

She favors a "save the best for last" mindset, tackles challenges with pragmatic optimism, and prioritizes community impact—launching Kozu-shima concert series and leveraging Love Live successes to permanently link their island to the event’s legacy. This dedication springs from genuine hometown affection and securing its future through idol work.

Available personality assessments alternately categorize her as ESFJ (highlighting social harmony and structured empathy) or ESTP (emphasizing energetic adaptability and independence), both noting strong communication and observational skills.
