Ao Sorakado is a 16-year-old girl living on Torishirojima island, born September 20th. She stands 160 cm tall, weighs 46 kg, and her measurements are 85-59-86. With blue hair, pink eyes, and a slim build, she dresses casually for her active life or in shrine maiden attire during festivals. Her approachable, slightly tomboyish look enhances her friendly image. As a Sorakado family member, she serves as a shrine maiden, maintaining sacred mountain festivals and honoring ancestral traditions. She has an unconscious twin sister, Ai. Ao's driving motivation is to save Ai by retrieving lost memories through interactions with "Seven Shadow Butterflies," entities embodying human memories and secrets. Reading these memories exhausts her, causing spontaneous, frequent naps anywhere—a habit islanders accept as normal. Outgoing and sociable, Ao treats everyone equally. She works part-time at a local candy shop, where children affectionately call her "Master" or "Sensei." Assertive in groups, she often takes command like a scout leader, yet impulsive actions make her unsuited for management. Kind, competitive, and stubborn, she is easily swayed and cannot refuse requests. However, she deliberately avoids romantic topics and exhibits "closet pervert" traits: misinterpreting innocent remarks erotically, becoming flustered, and earning nicknames like "pink-brained" from friends. Her daily routine blends shrine duties, candy shop work, and ghost story discussions. She is accompanied by Inari, a fox-like creature understanding human speech, symbolizing their deep bond. Memory reading exposes her to diverse knowledge, sometimes including adult topics, which contributes to her misunderstandings. Her core narrative involves balancing her mission for Ai with island life. She loves blue Hawaii shaved ice and table tennis. Her interactions with island children showcase her nurturing side, while the exhaustion from memory reading underscores the physical and emotional toll of her quest.
