Ayane is Suzu's rival, always being defeated by her and wanting to win at least once. Despite her appearance, she is actually 16 years old, and being underdeveloped she is also jealous of Suzu's sudden growth. 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 transport.
