Nichika Ubuyashiki is the second older daughter of Kagaya Ubuyashiki. Like the rest of her family, Nichika had large eyes with pale skin. She wore her short, white hair in a blunt bob with a fringe. Nichika wore a dark blue Hōmongi kimono with purple flowers as its pattern and a maroon obi with a cream yellow obiage and juban under everything. On the left side of her hair, she donned a yellow ribbon. Not much was known about her personality, but she does show a sense of loyalty for dying along with her twin sister when their father sacrificed himself to defeat Muzan.
