Since then, his goal has been to find a cure for her and turn her back into a human; to this end, he decides to become a Demon Slayer. He initially trains under Sakonji Urokodaki to learn the style; he later begins using his family's, based on the original breathing style,, eventually utilizing both to create a more sustainable fighting style.

Nezuko Kamado
See main article: Nezuko Kamado.
is the second child and oldest daughter of Tanjuro and Kie, who was turned into a demon during the massacre of her family and survived despite Muzan assuming that he failed to sire a sunlight-resistant demon. She serves as motivation and support for Tanjiro, who becomes a Demon Slayer to find a way to turn her back to normal. Though her mind was lost, she retains enough of her memories to keep herself from killing Tanjiro. After two years of hypnotic conditioning by Sakonji, Nezuko regards all humans as her family and will mercilessly attack any demons who threaten them. Instead of consuming human flesh, Nezuko regains energy from sleep, doing so for long periods of time after overexerting herself. Initially, she is unable to speak and wears a bamboo muzzle which Giyu Tomioka gave her to prevent her from biting others. The muzzle is later removed and she regains her speech, albeit broken due to not speaking for more than two years. Nezuko has the usual powers of demons, including regeneration, potent strength, and changing her physical structure, as well as a Blood Demon Art called that causes her blood to burn at will.

Nezuko's mind and humanity are eventually restored during the final battle against Muzan.
Zenitsu Agatsuma
is a cowardly boy who was forced to join the Demon Slayer Corps around the same time as Tanjiro in order to pay off his debts. He serves as comic relief, with his flighty personality serving as a contrast to Tanjiro's steadfast determination. He trained in the style with the former Thunder Hashira, but was only able to learn the first form; as a result, he often belittles himself despite being highly skilled. He has accompanied Tanjiro since joining him on a mission, partially out of his love for Nezuko, but also due to recognizing Tanjiro's honesty and kindness. His cowardly personality initially hinders him and he is only able to fight when unconscious or asleep, but he later learns to overcome his fears and take action when necessary. He wields a yellow sword with a lightning bolt design. He has a heightened sense of hearing, which allows him to distinguish a person's true character by the sound of their heartbeat and to track demons.

He is brash and prone to violence, and while appearing to be dim, has proven himself in battle. He normally hides his face behind a mask made from the head of his deceased boar mother, which he wears to honor her. When he first meets Tanjiro, he is initially hostile towards him, but they become friends as they fight together. He attends Final Selection at the same time as Tanjiro and Zenitsu and, unbeknownst to most, was the first to clear it.

Kanao Tsuyuri
is a girl who joined the Demon Slayer Corps at the same time as Tanjiro, Zenitsu, and Inosuke. She is the adoptive sister of Shinobu Kocho, the Insect Hashira, and is trained as her Tsuguko, a successor to a Hashira. She uses the style. Despite being a skilled fighter, she struggles to function without other's orders as a result of growing up in a poor, abusive household and being sold as a slave, leading her to shut off her emotions to cope. Even after Shinobu and Kanae rescued her and took her in, she would only act when ordered; Kanae gave her a coin to flip and use when she struggled to make decisions, which she relies on until Tanjiro befriends her and convinces her to stick to her intuition. Over time, she develops feelings for Tanjiro, to the point of risking her life to help save him when he is turned into a demon. She wields a light pink sword and possesses a heightened sense of sight that allows her to analyze and dodge attacks; after straining herself overusing this ability during her fight with Doma, it causes her to become blind in one eye. She is later revealed to have married Tanjiro, having two great-great-grandsons: Kanata and Sumihiko.
Genya Shinazugawa

He is harsh, independent, and obsessed with killing demons but mellows out later on when he fights alongside Tanjiro to save the Swordsmith Village. Unlike other Demon Slayers, he is unable to use breathing techniques or traditional sword fighting styles; instead he consumes parts of the demons he fights, which, through his special digestive system, allows him to temporarily gain their powers. How strong he becomes varies on the strength of the demon he devours, and this also makes him vulnerable to a demon's weaknesses. He wields a hand-held shotgun that fires special shot made with the same steel as the Demon Slayers' Nichirin sword, as well as a Nichirin wakizashi. He is the younger brother of Sanemi, the Wind Hashira, who shuns him but is unaware that he wants him to live a normal life.

She seeks to find a cure for demons, which requires the blood of higher demons, and enlists Tanjiro to help her, who offers some of Nezuko's blood and tries to get blood samples from members of the Twelve Kizuki. She is the only other demon besides Muzan who can create demons, but insists on only doing it for dying patients who have no other option and ensures they know the price of becoming a demon. After completing her research on a cure for Nezuko's condition, Tamayo sacrifices herself to lay an ambush on Muzan with Kagaya's help, poisoning him and weakening him enough to be killed.

He was later banished from the Demon Slayer Corps for his failure to kill Muzan and Michikatsu's betrayal.
