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.
Nezuko Kamado
Zenitsu also protects Nezuko multiple times when she is in danger, evident during Zenitsu's first meeting with Inosuke Hashibira and the battle against Enmu in the train. Eventually Zenitsu and Nezuko would marry and start a family as evidenced by their descendants.
But Demon Slayer introduced Tanjiro's main love interest briefly, and she doesn't really return until the end of the season, when she is fighting against him. His love interest that develops as the story goes on is Kanao Tsuyuri and their romance is quite adorable.
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.
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.
Tanjiro is ready to do anything, even die, if it means saving his sister. It becomes clear that Tanjiro's only choice is to join the Demon Slayer Corps himself and despite the intense, dangerous training, he doesn't hesitate. He loves Nezuko more than he fears demons or even death.
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.
In the Modern World, Tanjiro and Kanao had descendants named Sumihiko Kamado and Kanata Kamado.
Shizuka is seen often teasing Sanemi and making him annoyed, nevertheless, the two had still created a strong bond and relationship with each other. Eventually, after knowing each other for a while, Shizuka finally ended up having the courage and confessed, leading to them getting married after awhile.
However, in the Demon Slayer manga Muzan reveals his motivation for attacking the Kamado family. It turns out that Muzan attacked the Kamado family and specifically turned Nezuko into a demon in an attempt to create a demon that would be able to withstand being in the sunlight.
It's implied that the characters from the original series have all since died and have been reincarnated in modern day Tokyo in the final chapter of the series, but two key characters confirm that Nezuko Kamado and Zenitsu Agatsuma eventually did have a family together as their great grandchildren, Yoshiteru and Toko ...
Appearance. Toko bears a great resemblance to her ancestor, Nezuko Kamado, having the same waist-length black hair parted to the left side of her forehead, though her hair tips are much darker than her ancestor's and are closer to an actual red color than Nezuko's orange.
Zenitsu's debt is estimated to be around 600,000 yen in modern currency. This massive amount of debt likely came from his 7 ex-girlfriends. Despite all of them being beautiful, they treated Zenitsu like a slave, tricked him as well as robbing him of his money.
During Hashira Training, Zenitsu receives word that Kaigaku had become a demon, and that Jigoro committed seppuku as atonement.
However, Nezuko has been fighting her instincts and hasn't consumed human flesh. That begs the question of her ability to survive. While most demons rely on consumption of human flesh for survival, Nezuko relies on sleeping for long and sustained periods of time in order to slowly regenerate her energy levels.
Yoriichi had lost his wife and unborn child to demons, and he had a fateful encounter with Muzan Kibutsuji, the Progenitor of Demons. Yoriichi defeated Muzan in an instant, but he had a question for him before eliminating him, which allowed Muzan to escape.
Tanjuro Kamado was the name of Tanjiro Kamado's father. He passed away before the event of the main story of the Demon Slayer. It is not mentioned how long Tanjuro had passed before the story, but in several flashback scenes, we can see him interacting with a younger Tanjiro.
While Tanjiro and Kanao have certainly kissed, the exact moment of their first kiss was never shown.
He unleashes another shockwave and blows Obanai Iguro and Sanemi Shinazugawa away, however, Tanjiro Kamado holds on but loses his left arm. Tanjiro loses his arm.
Unable to fight back, Doma realized he was tricked but it was too late. He was soon decapitated by the combined force of Kanao and Inosuke, avenging Shinobu and her family.
5 Hashiras who die in Demon Slayer, and how it happens.
Upon seeing her for the first time, Zenitsu falls in love with Nezuko at first sight. 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.
Giyu also states how he feels about Shinobu, saying he thinks she is both hardworking and serious, along with stating that she talks to him a lot and mentions she looks pale, implying he might be worried about it.
