Description
Mao Hiiragi is a supporting character in the anime Love Live! Superstar!!. She comes from Kōzu-shima, a small island with which she maintains a deep and affectionate connection, thinking of her hometown as one big family. Alongside Yuna Hijirisawa, she co-founded the school idol group Sunny Passion, and the duo quickly became a powerful and well-known presence in the school idol world, even reaching the finals of the Love Live competition. Mao is a second-year student when first introduced, later advancing to third year and eventually graduating by the end of the second season.

Mao is outwardly calm, observant, and reserved, speaking less than her energetic partner Yuna. Despite her composed and cool demeanor, which has earned her the nickname Sexy Night of Sunny Passion due to her beauty and mature poise, she harbors a more emotional side. Yuna notes that Mao becomes very emotional when watching movies, a vulnerability that her partner finds endearing. Her life outside of being an idol is ordinary, and she believes she would have been a boring high school girl if not for school idols.

Her motivation for becoming a school idol is closely tied to Yuna. Mao describes Yuna as cheerful and energetic like the sun, always bringing her new surprises, and it was Yuna who inspired her to pursue this path. Together, they formed Sunny Passion with the goal of livening up the island they love. Within the group, Mao takes on the responsibilities of gathering information and coordinating the practice menu. She creates intense practice schedules and is strict about waking up early to train, and she and Yuna work together on costumes and songs. Despite her serious approach to practice, Mao also enjoys teasing Yuna, such as when she jokes about skipping ice cream for figure improvement.

In the story, Sunny Passion serves as a rival group that inspires Liella! from a distance. Keke Tang was inspired by Sunny Passion to move to Japan and become a school idol. Despite the rivalry, Mao is kind, friendly, and supportive toward Liella! members. She says she was initially drawn to them because they shone so brightly, and she saw them as people who could bring out the best in each other. Even after Sunny Passion is eliminated from the Love Live remote judging by Wien Margarete in the second season, Mao courageously gives advice to Liella! and later attends the national stadium to cheer for them. This supportive role continues throughout the series, showing her maturity and generosity.

Mao is notably tall, with a height of 169 cm, making her one of the tallest characters in the Love Live! franchise. She has long purple hair with pink highlights, side-swept bangs, purple eyes, and thick prominent eyebrows, which contribute to her distinctive appearance.

Developmentally, Mao remains a steadfast figure. Her arc does not involve major personal conflict but rather highlights her role as a seasoned senpai who gracefully transitions from rival to mentor and supporter. Her ability to balance a calm exterior with a hidden sentimental nature, and her dedication to both her partner and the larger school idol community, define her character. She demonstrates that strength can coexist with kindness, and that competition does not preclude genuine mutual respect.
