Hinaki Ubuyashiki

Hinaki Ubuyashiki is a minor character in Demon Slayer: Kimetsu no Yaiba. She is the eldest daughter of Kagaya Ubuyashiki (the leader/Oyakata of the Demon Slayer Corps) and Amane Ubuyashiki, and the oldest of their quintuplet children (which includes Nichika, Kiriya, Kuina, and Kanata).

She and her sister Nichika (the second oldest) often served as aides/assistants to their father, helping during meetings with the Hashira and carrying out duties with great commitment.

Hinaki is depicted as a young girl (around 8 years old) with pale skin, large purple eyes, and white shoulder-length hair in a blunt bob with bangs, typically adorned with a red ribbon on the right side. She wears a traditional dark blue kimono with purple floral patterns.

In personality, she is quiet, kind, highly dutiful, and described by her brother Kiriya as particularly smart and skilled.
