Ginoza is a female of average height and a frail build in her 50's. She has unstyled mid-length brunette hair that is beginning to gray and green eyes. She constantly wears a blank expression so it is unknown if she is aware of others or her environment.
Her personality at present is unknown due to her illness; however, both her ex-husband and son worry about her.
- Sae suffers from a disease called Eustress Deficiency Syndrome. Since Sibyl does not acknowledge this illness, such people are confined to therapy facilities. However, the conditions there are so terrible that Ginoza makes arrangements for a drone clinic at her home.
Masaoka is her former husband and the biological father of their son, Nobuchika. It is possible that her illness played a role in their divorce or began after Masaoka was deemed a latent criminal. Masaoka feels great guilt about things and because of the way they have affected his family, he tells Sae that his life is now devoted to their son's happiness.
- The name Sae can mean "thread, silk" (紗 sa) and "branch" (枝 e).
- The surname Ginoza can mean "convenience" (宜 gi), "field, wilderness" (野 no) and "seat" (座 za).
