Kiyo Terauchi (寺てら内うち きよ Terauchi Kiyo) is a servant of the Butterfly Mansion.
Kiyo is a girl with light skin and a set of circular, black eyes. She has shoulder-length black hair with thin bangs framing her face, along with two pink butterfly clips on each side of her head.
Kiyo wears a long, white nurse dress tied with a dark, reddish-pink bow around her waist. She also sports white socks and shoes.
After her family had been killed by Demons, Kiyo was taken in by the Butterfly Mansion.
Rokuta Kamado (竈門かまど 六ろく太た Kamado Rokuta?) was the youngest brother of Tanjiro Kamado. He was killed by Muzan Kibutsuji.
Like the rest of his family, Rokuta has light skin and dark red eyes along with white pupils. He wears his black hair in a bowl-cut and wears a blue kimono with white diamond patterns.
While not much of his personality is known, Rokuta seems to have a good relationship with his parents and siblings.
Rokuta grew up on a mountain alongside his older siblings and mother. He is the youngest son of the Kamado family.
It appears that Rokuta had a positive relationship with his father as Nezuko mentioned him to be lonely and clingy to Tanjiro after their father's death.
