After Doma's demise, Kanao wears Shinobu's hair pin instead of Kanae's, as the latter was destroyed during the fighting. Furthermore she loses visibility in her right eye due to unleashing the final form of Flower Breathing, even though the eye is unaffected visually.
8 Kanao Tsuyuri - Demon Slayer
Kanao never spoke before being adopted into the Demon Slayer Corps and continued to have difficulty speaking after officially joining the other demon slayers. To help with her indecisiveness and other struggles, Kanao often flips a coin she received as a gift.
Kanao appears as one of the nearly twenty participants in the Final Selection, and is one of the five to survive. She says nothing in her appearances, merely gazing at a butterfly and ignoring the commotion around her.
Enhanced Vision: Kanao possesses extremely sharp eyesight, being able to accurately predict her opponent's next attack and movements by simply observing the subtle shifts of their muscles, joints and the slight movements of their eyes.
After returning to his human form, Tanjiro loses the ability to see from his right eye, the iris of which is now a dull pink-gray color and the pupil black rather than its original white.
The fuming rage that Tanjiro felt from seeing Daki destroy human lives helped him push past his limits while also making him bleed through his eyes in anger, resulting in his eye colors changing to bloodshot red.
Gyomei is blind, thus explaining the reason for the lack of pupils in his eyes. He was blinded due to a fever he had when he was a child.
1) Obanai. Obanai, without a doubt, has one of the most unique eyes in the entire series. His irises are of two different colors and this condition is called heterochromia. Obanai's eyes are quite appealing and the colors are beautiful as well.
Kanao is a dedicated demon slayer and a good friend to Tanjiro. She hardly ever speaks, even to Tanjiro. Instead, she flips coins to make her decisions for her, making her oddly similar to Two-Face from the Batman comics. She might have a few words for Tanjiro, though, with or without that coin.
Kanao Tsuyuri, Shinobu's adoptive sister, holds the rank of Tsuchinoto, one rank higher than the aforementioned Slayers. As a Tsuguko, she is expected to succeed her Hashira sister in the future.
After the battle, Kanao starts wearing Shinobu Kocho's hairpin instead of Kanae's as the latter is broken as a result of her combat, and she also loses the ability to see out of her right eye as she uses the final form of Breath of Flower to defeat the Upper Moon.
Later it is revealed that he married fellow slayer Kanao Tsuyuri. In the Modern World, Tanjiro and Kanao had descendants named Sumihiko Kamado and Kanata Kamado.
Kanao and Tanjiro would eventually marry and start a family, having two great-great-grandchildren by the names of Kanata Kamado and Sumihiko Kamado between them.
Kanao, on the other hand, is completely blind in her left eye. She used her final form during her fight with Doma, which allowed her to track the movements of the demon when he was in slow motion.
Kanae Kocho, the Flower Hashira, was Shinobu's elder sister and adoptive elder sister of Kanao Tsuyuri.
Post-Transformation
Sensing their despair, Doma offered a chance to him and turned both Gyutaro and Daki into demons.
The muzzle serves as a representation of Buddhist practices. First, it gags Nezuko, preventing her from speaking like a Buddhist monk's vow of silence, but it also is there to suppress her desire to eat humans. Through a Buddhist lens, Nezuko's muzzle is the symbol of a Buddhist monk.
Kanao's emotionless smile. Due to the abuse that Kanao suffered as a child by her parents, she completely repressed her emotions as a defense mechanism.
A Nisei (second-generation Japanese-Canadian), Kanao Inouye was born to immigrant parents in Kamloops, British Columbia.
Demon Slayer's adorable icon Nezuko has stolen fans' hearts for five key reasons, earning her the title “Best Girl” of the series.
Since she's the Love Hashira, it just makes sense for Mitsuri to be one of Demon Slayer's kindest and most compassionate characters. She always compliments the people around her, even if it's just mentally. She can also find everybody's best qualities.
The young Tanjiro is not only one of the greatest demon slayers, but thanks to his kind nature, he's also one of the most honorable characters of the series. Tanjiro not only showed selflessness and love towards his sister and the people he cared for but even showed kindness towards his demonic enemies.
Tengen Uzui
He is the fastest Hashira, and the second physically strongest. Obviously, then, Tengen Uzui is rather proud. He is demanding, fussy, boastful, and prone to selfishness. But he is also ultimately kind and caring, with great love for his three wives as well as the other Hashira.
He trained his mind and body with the hope that one day he could eradicate all demons. Gyomei is extremely emotional and caring and is always concerned for those around him. This could be the main reason why he is always crying in the Demon Slayer series.
