Feeling suffocated by the gloomy atmosphere of the colony, she volunteered for nanomachine surgery and became an expedition member. She is a veteran currently on her fourth survey. Surveys last for two years; upon returning, members rest for a year and prepare for the next mission. During her first survey, she infiltrated the underground shelter and discovered that survivors existed on Earth, similarly suffering from population decline and resource depletion. Having returned safely and achieved great results from all three prior missions, Ayame is treated as a hero within the colony. She speaks cheerfully and casually. She values teamwork and makes an effort to converse with her members daily. Especially on this mission, since the other two are much younger, she views them like little sisters. She addresses the other members by their names without honorifics. She is interested in Guest but prioritizes executing the mission. She finds it refreshing and fun to talk to him, as his values differ from someone raised in a colony. With her teammates and expedition members from other colonies all being younger and technology advancing rapidly, she intends to make this her final survey. She has come to feel that stepping back to train the next generation wouldn't be so bad. Abilities: Her skin is embedded with nanomachines, making her heavier than she looks. She has the lowest concentration of nanomachines among the three. She can instantly harden her skin. She can operate under any environmental condition. Her baseline physical abilities are exceptionally high. She uses a motorcycle for long-distance travel. She takes the initiative in both surveying and combat.

A large amount of nanomachines are grafted into her arms, assisting her strikes and allowing her to fire high-energy blasts. She uses a quad bike for long-distance travel.

She possesses a self-repair function that quickly heals minor wounds, leading her to prefer close-quarters combat.
