Aoi Akane is a first-year student at Kamome Academy who projects a popular, cheerful image that masks deeper complexities. She has indigo hair and eyes, initially styling her hair in looped pigtails before wearing it down from Chapter 101 onward. She wears the standard school uniform but adopts distinct traditional attire with magenta flowers in her hair and a light teal coat while serving as a kannagi under No.6. Her childhood was troubled by parental deceit and persistent bullying, leading her to suppress emotions and craft a persona of perfection and approachability upon entering Kamome Academy. This facade earned her widespread admiration and the informal title of the school’s "queen of popularity," though she internally harbored resentment and loneliness. She maintains a close friendship with Nene Yashiro, regularly sharing supernatural rumors despite claiming to dislike scary stories. Her dynamic with childhood friend Akane Aoi is fraught; she consistently rejects his daily confessions, humorously citing that marriage would render her name "Aoi Aoi," though jealousy surfaces when he appears romantically involved with others. A turning point occurs when Akane confronts her artificiality, revealing he has always seen her genuine nature and loves her regardless, which fractures her facade and leads to implicit mutual acknowledgment of their feelings. She later gains the ability to perceive supernaturals like Hanako and No.6. Abducted by No.6, she agrees to become a kannagi, a role granting her control over insect swarms and a giant centipede. Sacrificed to extend Nene’s lifespan, she becomes trapped in the Far Shore, where her regret centers on never openly reciprocating Akane’s feelings. After being rescued, she demonstrates greater emotional openness. Additional traits include academic excellence, a concealed fear of lightning, and preferences for giraffes, winter nights, desserts, and solitary walks. Her name’s kanji translates to "red root hollyhock."
