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.
Nezuko marries Zenitsu Agatsuma in the Demon Slayer series.
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'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.
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 ...
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.
After the battle, Tanjiro returns home with his sister and friends. Later it is revealed that he married fellow slayer Kanao Tsuyuri.
Unfortunately, Gyutaro spots Inosuke and stabs him right through where his heart should be with a sickle imbued with deadly poison.
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.
Eventually Zenitsu and Nezuko would marry and start a family as evidenced by their descendants.
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.
Doma grew fond of her due to her beauty and singing ability, intending to keep her alive until she died of natural causes.
After his treachery, Kaigaku later becomes Zenitsu's archenemy. His cowardice would later lead him to his downfall when Zenitsu overcomes his insecurities as Kaigaku mocks Jigoro. Kaigaku's Thunder Breathing training would lead to his Blood Demon Arts being related to lightning.
Yes. He gets married to Kanao Kocho and have kids.
When the two originally meet, Zenitsu develops a disdain for Tengen after he attempted to kidnap the girls of the Butterfly Mansion, and due to his flamboyant personality, even referring to him as the "god of idiots." Tengen's frivolous attitude doesn't sit well with Zenitsu's character and often annoys him.
She is a demon and the younger sister of Tanjiro Kamado and one of the two remaining members of the Kamado family.
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.
The reason why Nezuko Kamado acts like a baby now, unlike most demons in the show. When Nezuko was turned into a demon, she went into a childlike state. Other demons just became a darker, twisted version of their past self, minus a few memories.
During Tanjiro and the rest of the Hashiras' showdown with the Demon King Muzan, Tanjiro is mortally wounded and dies. At the same time, Muzan receives a particularly fatal lil' booboo himself. As Muzan is about to shuffle off the mortal coil, he uses the last of his powers to turn Tanjiro into a demon.
Zenitsu Survives The Attack
Daki and Gyutaru are just other demons that Zenitsu is fighting against.
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 Chapter 205, we see Obanai and Mitsuri reincarnated and married, as they promised before they died, and they are running a restaurant together. In the volume extras it is revealed that they have five kids.
Furthermore, to Tanjiro, Inosuke and Zenitsu's surprise, the Sound Hashira has three incredibly beautiful wives.
