Kiriko Aoki trains as a candidate pilot for the Shimoji Airbase defense force. She possesses a cheerful and optimistic personality, marked by a scatterbrained quality that results in occasional forgetfulness and disorganization. Kiriko adores animals, shown through her persistent attempts to befriend the base's aloof cat, Alice "Admiral." She is an only child. Her energetic and sometimes impetuous nature contrasts Mikaze Honjou's laid-back demeanor and aligns somewhat with Ayamo Nakamura's fiery temperament. Kiriko feels frustration when the senior Meteor Sweeper candidates overlook her, perceiving this neglect as an obstacle to her goal of becoming a Meteor Sweeper pilot. She has auburn hair and green eyes.
