Description
Kirie, an orphan from Ramaha, grew up alongside Emma as a childhood friend and met Reona at the orphanage. Her carefree and curious nature drew her to the last known Yufang, Old Sabu, after he collapsed near Mount Shio. She assisted him with medicines and expressed keen interest in the world beyond, eventually persuading him to teach her to fly planes.

When a mysterious man pressured Old Sabu to build war machines, the old man refused. Noticing Kirie, the stranger inquired if she was his daughter. Sensing danger, Old Sabu denied any relation, chased her away, then burned his hut and vanished. Kirie never saw him again and built a small landmark near the ruins, which she visits after missions to seek his blessings.

Recommended by Emma, Kirie joined the Kotobuki Squadron. Hot-blooded and quick to anger, she often clashes with strong-willed individuals like Chika. Yet she holds no lasting grudges over trivial matters and generally gets along as easily as she argues. Cheerful, fun-loving, and childish, she adores pancakes, which never fail to brighten her mood. She enjoys playing and mock-fighting with children and remains cordial with acquaintances. A loyal subordinate and friend, Kirie holds her associates in high regard, particularly respecting Reona, who is the only one able to calm her rages.

Her primary motivation as a pilot stems from curiosity, inspired by tales of the Yufang and her time with Old Sabu. A naturally talented aviator, she is the squadron's best acrobat and excels with any aircraft, though she lacks theoretical knowledge. As she matured, she temporarily lost sight of this drive and questioned her purpose upon seeing squadmates spend earnings on loved ones. Later experiences reawakened her past ambitions and reinforced her desire to explore the world.

Kirie has a medium build, short black hair, and brown eyes. She typically wears a red overcoat and short frilly pants. Her flight gear includes a brown aviator hat with goggles and a blue scarf, reportedly a gift from Reona. As a child, she wore a red dress and brown sandals.

In the Harukaze Gaiden spin-off, Kirie visits Kaichi restaurant for pancakes and accidentally reveals her identity during the Harukaze Squadron’s discussion about emulating Kotobuki. She initially denies who she is, but Chika’s arrival confirms it. They argue over Kirie sneaking off to eat alone, but eventually perform a skit to demonstrate teamwork despite differences. Afterwards, they flee together to avoid Reona’s reprimand.

Kirie is of legal age but dislikes alcohol. She does not know what a swimsuit is and cannot swim. She had never seen a fish until a particular episode. Unlike most natives, she recognizes tanks and aircraft carriers.
