Yuzuno Hironaka

Hironoka Yuzuno is Motomiya Mao's biological mother and the ex-wife of Motomiya Kaitou. She worked as a nurse.

Yuzuno is depicted as apathetic individual towards her family. She would often speak coldly and stingy to Mao. When she was younger, she was described by Kaitou as being the type of person who would not cry at a graduation ceremony. Back then, she always seemed to have money troubles and kept working to the point where she could not stand anymore. She easily believes other people and had put trust in others who easily took advantage of her.

Yuzuno is also a person who gets lonely very easily, as shown when she starts having an affair because her former husband Kaitou was so busy with work. Although she seems to have changed a little over the years, she still is a bit selfish and does not think much about her past actions when she doesn't ask Mao to forgive her for her actions, but instead asks her to come to live with her.

When she was in highschool and dated Motomiya Kaitou, she had shorter hair. Ten years ago, Hironaka Yuzuno had long hair that goes past her shoulders. She is often seen wearing a long-coat dress the has a low collar and a belt at her hips.

Hironaka Yuzuno currently has short hair, with bangs across her forehead. Her appearance looks a little older now, as she has small wrinkles around her eyes. She still seems to wear the same style of clothing as she did back then, but does not wear as much jewelry.
