Yoshiteru Agatsuma and Toko Agatsuma are siblings that look very similar to Zenitsu and Nezuko respectively. Therefore, it is safe to assume that Zenitsu and Nezuko end up together and have kids in the future. This is proof that Zenitsu loved Nezuko and she too came to love him at some point in time.
Zenitsu Agatsuma
She apparently views Zenitsu as a "weird dandelion" and did not initially seem to reciprocate his feelings. Although the two are rarely seen interacting together, Zenitsu treats her with affection and care.
The pairing of Zenitsu and Nezuko is arguably the most popular canon ship in Demon Slayer. Zenitsu is naturally an affectionate person and easily drawn to beautiful women.
Eventually Zenitsu and Nezuko would marry and start a family as evidenced by their descendants.
This ship is one of the most well-known inside the fandom because of Zenitsu's clear attraction toward Nezuko. People ship them likely because they love his devotion to her and want Nezuko to reciprocate his feelings once she becomes a human again.
Nezuko Kamado
A few episodes later, Nezuko is 14 years old, however, physically, she has not aged since that faithful and tragic day, and that's something that will not change unless Tanjiro finds a cure.
Later it is revealed that he married fellow slayer Kanao Tsuyuri, In the Modern World, Tanjiro and Kano had Great-great-great grandsons named: Sumihiko Kamado and Kanata Kamado.
Nezuko most likely has those orange tips on her hair because of the demon blood in her. Tokitou, Inosuke and Kanao (as seen in the latest cover art featuring her) most likely has coloured tips on their hair most likely because of the influence of their particular Breath Styles.
Nezuko's Blood Demon Art, called Exploding Blood, allows her to ignite her blood into pink flames or even conjure it from thin air.
Nezuko apparently can use Sun Breathing to a certain extent as a member of the Kamado family, since she eventually becomes immune to sunlight. The fact that Tanjiro, who uses Sun Breathing, becomes immune to sunlight when Muzan turns him into a demon shows that Sun Breathing is the source of sun immunity for demons.
After embracing Tanjiro, Nezuko speaks as a demon for the first time in the manga, telling Tanjiro that she's happy and fine. While Nezuko's appearances from here through the rest of the series are sparse, fans are at least shown without a doubt that Nezuko is able to speak as a demon.
Kanao used the Final Form to defeat Doma, although it rendered her almost blind in her right eye. She later uses the technique once again to administer the demon antidote to Tanjiro.
It is confirmed in the Volume 23 extras that Inosuke and Aoi did eventually end up together and that they have two great-grandsons, one of which is Aoba.
She is a demon and the younger sister of Tanjiro Kamado and one of the two remaining members of the Kamado family.
Nezuko is physically 12, and chronologically 14 since she became a demon in age of 12, and it already past 2 years after that time.
While stuck physically at age 12 because of the whole demon thing, Nezuko is 14 chronologically.
Most importantly, Nezuko upholds a vow of silence by remaining mute throughout the series. 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.
[Demon Slayer] Finally, Giyu Tomioka and Shinobu Kocho Married_1.
Aoba Hashibira ( 嘴 はし 平 びら 青 あお 葉 ば , Hashibira Aoba?) is the great-grandson of Inosuke Hashibira and Aoi Kanzaki.
Inosuke Hashibira (嘴平伊之助) is a demon slayer of the demon slayer corps and one of the traveling companions of Tanjiro Kamado and a main protagonist in the Kimetsu no Yaiba: Demon Slayer series.
During his second encounter with Muzan Kibutsuji, he injures his right eye in the Infinity Castle. As the battle progresses, Tanjiro suddenly collapses and his wound begins to form a large mass over his right eye due to the poison inflicted on him by Muzan.
Appearance. Kanao is a youthful little girl that has large gentle eyes with irises that go from pink to lilac. She has long black hair tied with a butterfly pin fastened into a ponytail to the right side.
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.
Nezuko survives without eating humans because unlike other demons who need human flesh to get back their energy , nezuko gets back her energy sleeping . As we see in the anime she sleeps in the box Tanjiro carries on his back .
The now-iconic bamboo muzzle serves as a way of stopping Nezuko from using her teeth, and also keeps her from tasting human blood, which would cause her to lose control of herself.
