Personality & Character
Yuki is an easy-going and carefree woman, sometimes unsystematic as she has to be cooked for and woken up by her younger brother. Although, she will get serious and determined when needed. She is also very caring and often worries over her brother where she even cried greatly for Inaho, after he was shot on the left eye, under the initial assumption he was going to die. Yuki puts the people's safety above her own. (AZ: "The Children's Echelon")
Yuki is a slender woman of pale skin and brown eyes. Her hair is black and straight, reaching down to her back. She wears her soldier's uniform which consists of a white long-sleeved shirt, blue tie and pencil skirt.
Little is known about her past, besides her parents who passed away when she was only a child and Inaho was only a baby. Raised at a government foster facility, she never had the courage to tell her brother that her parents died in the First Orbital War and acted as a sisterly figure. Unfortunately for her, she was unprepared to the life of being a parental figure when she had to move out of the foster home and found it difficult to take care of her brother properly. Inaho was quick to learn and eventually became her caretaker.
She later became an instructor at the high school in Shinawara.
Inaho is Yuki's brother. They live together in an apartment after her brother got her thrown out of the orphanage they lived in and Inaho was soon quick to raise her. While her brother seems like a neat and organizing person, Yuki is a little lazy and carefree, although they get along well-enough in a home. She is also very caring towards Inaho, often worrying over him. Yuki later states that as Inaho's sister, she is one of the only people able to read his apparently unchanging expressions. She also made his signature bookmark and put it in his Sleipnir for him to find. It is similar to Asseylum's locket. It is implied that Inaho values it as he keeps it attached to his comm link and looks at it during times of doubt. One promise he wanted to make for his sister was to make rolled omelets as a way to remind her of the parents he never known.
