Kanata Ubuyashiki (産うぶ屋や敷しき かなた Ubuyashiki Kanata?) is the youngest daughter of Kagaya Ubuyashiki. She currently serves her older brother, the current head of the Ubuyashiki Household, Kiriya Ubuyashiki.
Kanata has pale, light skin and a set of large, dark eyes. Her hair is shaped into a blunt white bob haircut similar to the rest of her siblings. She adorns an elongated wisteria headpiece on the right side of her head as opposed to the left side like her brother.
During the Final Selection Arc, Kanata wore a purple, flower-patterned kimono and a green obi. She wears a black obi during the Infinity Castle Arc.
Giyu Tomioka (冨とみ岡おか 義ぎ勇ゆう Tomioka Giyū?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is a Demon Slayer of the Demon Slayer Corps and the current Water Hashira (水みず柱ばしら Mizu Bashira?).
Giyu had an older sister, Tsutako Tomioka, who died protecting him from a Demon on the day before her marriage. After that incident, he was left in the woods and discovered by the former Water Hashira, Sakonji Urokodaki and was taken under his wing and trained to be a Demon Slayer.
Giyu is also the close friend of Sabito, and was defended by him during the Final Selection, and became a Demon Slayer despite failing to kill a single Demon.
