Yuki Himezuru

Yuki Himezuru is a inhabitant of Planet Azure and the adoptive older sister of Hinata Himezuru.

Appearance
Yuki is an older woman with long orange hair tied into a ponytail, and brown eyes like her sister. She wears a yellowish-orange sweater shirt with light yellow jacket with folden sleeves with cross cuff links, jeans, and black slippers. At work, she wears a white doctors coat over her shirt.

At the pool, Yuki wore a black and yellow bikini, with the straps of the top half wrapping around her neck for stability.

Personality
Yuki is a very outgoing and optimistic person who shows some signs of perverseness. She doesn't seem to mind taking in outsiders in her home, and can be very spontaneous. However, she has shown to have a more serious and knowledgeable side to herself as well, and cares very much to the well-being of others. Her relationship with Tōya Kagari and Hinata Himezuru demonstrates this, as she adopted the both of them once she became old enough, having made a promise to them both that they would be a family in the future.

She is well aware of the existence of Unions, containing an incredible amount of knowledge about their biology and treatment. At work, Yuki is far more strict and takes a no-nonsense approach with her patients.

Early Life
When Yuki was 13 years-old, the serial killer known as Ripper escaped from his transport to his cell, and wound up in her household - he effortlessly murdered her parents as Yuki hid under their corpses. She was raised in the same orphanage as Hinata and Tōya Kagari. When she came of age, she left the orphanage and adopted the two of them. She rarely comes home to eat dinner with her family and is often working at the Neo Yokozaki City University Hospital as a doctor. She gets on fairly well with Mei Amanohokosaka, looking after her father who has spent the last 10 years in hospital.
