Kanao is a girl of short stature with large eyes and long black hair tied into a side ponytail with a butterfly ornament similar to Shinobu. She wears the standard Demon Hunter uniform but with a long pleated skirt instead of a Hakama and white laced up boots. Kanao also wears a white cloak with a ornament attached on the side.
An indecisive and quiet girl. Due to her past, she doesn't do any good during her childhood like what her master said, admitting her to be so useless in making a decision. She flipped her coin, given by her older Kochou, to decide which fate she must foresee.
But her behavior has improved when she met Tanjiro Kamado, which she regained her human side for making her own decision and lived as free without waiting for anyone ordering her around.
She takes a special interest in Kamado. Thanks to his positive interaction she is slowly opening up. It is hinted at, in an extra chapter, that he will become her "special someone" (aka love interest).
Kanae took an interest in Tsuyuri when she saw her being led away as a slave on the bridge. Along with her sister Shinobu, they purchased Tsuyuri from her master and trained her within the Butterfly Estate. Kanae was the person who gave Tsuyuri the coin she uses to make decisions whenever she is indecisive. 
Shinobu was originally against taking Kanao in due to her indecisive nature. Initially, she saw her as a useless, if not dangerous, person. After Kanae's death, she was responsible for helping her and entrusted her with avenging Kanae's death while using herself as a decoy.
Her death caused her to show anger and want to take revenge to the person, Doma, who killed both her two lovable masters.
Much like Shinobu,Kano held strong resentment and hatred for the Upper Moon Two,Doma due to him having killed their Older Sister Kanae,this grudge became even deeper when Doma successfully defeated and ate her other Older Sister Shinobu during their duel,Kanao herself seemed to have become vindictive with her Grudge to the point that she took immense pleasure and satisfaction at calling Doma out on his inner "Emptiness" and non existent Emotions and insulted him cruelly by asking him why he was even born and why he continued to bother living due to not feeling any joy,satisfaction and fullfillment in any of his actions or accomplishments or feel any attachment,love or closeness with anyone and not feeling any rage,sorrow or regret when losing someone.
Kanao was revealed to have lived an impoverished lifestyle before she was taken in by Kanae and Shinobu. Her family was not able to feed or support her so she was sold off as a slave. She was purchased out of slavery by the Kochou sisters and was taken to the Butterfly Estate. Due to her traumatic past, she had social issues when it came to making decisions, such as not eating unless she was told to. Kanae gave her a coin and instructed her to flip it if she ever needs help making a decision in order to help her overcome her indecisiveness.
