Yuki Kaizuka

Height: 168 cm

A warrant officer of the UFE (United Forces of Earth) and a pilot for the Mustang Platoon. She is a woman of average height with straight black hair that reaches her back and side bangs that ends right above her hazel eyes. She is mostly seen with her soldier's uniform which consists of a plain white dress shirt, a blue tie, and a navy blue pencil skirt.

Not much is known about her past except that her parents passed away when she was at a young age and her brother, Inaho, was only a baby. The two of them grew up at a government foster facility and later on began living together in an apartment. Unfortunately for Yuki, she was not prepared to raise her younger brother as a parental figure resulting in Inaho taking care of her instead. Currently, she is an instructor at Shinawara high school and is the pilot of the KG-7 Areion Terran Kataphrakt.

Being an easy-going and carefree woman, she often relies on her younger brother, Inaho, to take care of her who often has to wake her up and cook for her. However, she shows that she is able to be serious and focused on her goal when needed. Yuki is also a very caring person, often worrying about others and putting their safety above herself, especially when it comes to Inaho. She greatly cares for her younger brother and often worries about him.

Yuki shows that she is a skilled pilot when piloting the KG-7 Areion during the second Earth-Mars War.
