Ayane is Suzu's rival, always being defeated by her and wanting to win at least once. The fact that she constantly loses makes Suzu somewhat doubtful of her ability as an individual. Despite her appearance, she is actually 16 years old, and being underdeveloped she is also jealous of Suzu's sudden growth. Despite this she is close friends with Suzu, usually being the first one to come over to her house when it rains and staying over when Suzu's mother had disappeared. She is very arrogant saying she is the prettiest girl on the island. She is deathly afraid of Machi, her older sister, and uses anesthetic darts as her main weapon. She hopes to take Ikuto captive and trump Suzu. She is a miko at the local shrine along with Machi and their mother Chizuru whom Ikuto mistook for her sister at first.
She also frequently uses a giant ostrich named Monjiro as transportation. She is a target for bad luck usually ending up in a position where she is stuck, usually because of Machi. Due to this she is used to bad situations, such that she keep a carnivorous plant that bits her think it is only playing. Her body has great tolerance to pain due to her many mishaps. She loves spicy food, as Machi would not take it from her. RandomnessAfter accidentally kissing Ikuto, she finds that she cannot approach him without getting flustered as she developed real feelings for him. Ironically, despite her scheming personality she is the only one who did not try to spy on or sabotage Ikuto and Mei Mei's date actually giving them a scroll with suggestions on the best date-spots on the island. She is very intelligent being the best prankster on the island.
