But
It is implied in an extra chapter following the end of the Functional Recovery Training Arc that she may have had a crush on Tanjiro.
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.
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.
It's unclear if this means Inosuke is crushing on Tanjiro, but fans should consider that social ideas like gender and sexual orientation are foreign to the beast known as Inosuke.
She comes to care about both Tanjiro and Nezuko and is visibly concerned about them, even letting them rest at her estate so they are able to recover from their injuries. Tanjiro is visibly sad when he hears about Shinobu's death.
Furthermore, Tengen also declares that they must value their lives above all others as they are precious to him. After the events in the Entertainment District Arc, Tengen also becomes more friendly towards Tanjiro, Zenitsu, and Inosuke.
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.
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.
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.
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.
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.
Tanjiro and Kanao would eventually marry and start a family, having two great-grandchildren by the names of Kanata Kamado and Sumihiko Kamado between them.
Yae ( 八 や 重 え , Yae?) is a young woman who joins Giyu Tomioka on his travels in Giyu Tomioka's Story after her father Matazo transforms into a demon.
Aoi and Tanjiro seem to have formed a friendship. Tanjiro respects Aoi for her help and care while he, Inosuke, and Zenitsu resided at the Mansion. He also thanks her for her work and assistance, which she seems to appreciate.
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.
Many people brush off Inosuke as yet another tsundere, but that reasoning is only partially correct. As a child, he was abandoned by his mother and coincidentally, was adopted by boars.
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.
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.
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 .
Nezuko becoming a demon was technically planned in that she was another one of Muzan's experiments, but the type of demon she would become would surprise everyone.
In the eighth episode of the "Entertainment District" arc, Upper Six Gyutaro couldn't stop gushing over his man-crush on Tengen. The Sound Hashira, however, declared that if Gyutaro thinks Tengen is all that, he'd be blown away by some of his fellow Hashira.
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.
i know, though, some believe he loves hina (21) the most, because he had the most interaction with her in the manga and they have the most “husband-and-wife” feel. we also have to remember that suma (19) was tengen's first chosen wife—they both personally agreed to letting hina and makio (20) into their relationship.
