Kanata Ubuyashiki is a daughter and one of the lastborns of Kagaya Ubuyashiki. She currently serves her older brother, the current head of the Ubuyashiki Household, Kiriya Ubuyashiki.

She adorns an elongated wisteria headpiece on the right of her head. Kiriya wears the same headpiece on the opposite side instead.

She is first named in Chapter 144. However, her headpiece was initially obscured which made identification impossible until Chapter 147. Though mistakenly drawn on her left side, its shape confirms her identity to be the same as the Final Selection examiner. (The only other surviving sister has a short headpiece.)
