After selling charcoal in town, Tanjiro returns home to find his whole family dead. Only his sister Nezuko has survived -- but she’s changed.
Tanjiro departs for the mountains with Nezuko in tow. En route, he smells blood coming from inside a temple, where he stumbles upon a gruesome scene.
Under Sakonji, Tanjiro trains to become a member of the Demon Slayer Corps. But before he can join, he'll have to qualify for the Final Selection.
The Final Selection begins. Tanjiro and the other trainees must survive for seven days among demons trapped alive by Demon Slayer swordsmen.
Tanjiro is among the four survivors of the Final Selection. After acquiring a new sword, he receives orders for his first mission as a Demon Slayer.
For his first mission, Tanjiro heads northwest to a village where he meets Kazumi, whose lover has disappeared without a trace.
Tanjiro dives into a swamp realm to confront a swamp demon who's split into three, but the demon refuses to tell him anything about Muzan Kibutsuji.
For his next mission, Tanjiro heads to the bustling area of Asakusa, Tokyo to find the demon hiding among the crowds.
While taking refuge inside a home concealed by Yushiro's spell, Tanjiro protects those inside from demons sent by Muzan Kibutsuji.
Nezuko goes toe-to-toe with Susamaru and her deadly volley of temari balls, but Tamayo intervenes with her own spell before the battle intensifies.
Tanjiro travels south-southeast for his next mission. On the way, he encounters fellow swordsman and Final Selection survivor, Zenitsu Agatsuma.
As Zenitsu cowers in fear inside a mysterious rotating house, Tanjiro faces a drum-beating demon and an odd sword-wielding man wearing a boar mask.
With the house turning with each beat of the drum, an injured Tanjiro struggles against Kyogai’s overwhelming attack.
Now outside the cursed drum house, Tanjiro finds a beaten and bloody Zenitsu, and is confronted by the belligerent man wearing a boar's head mask.
Tanjiro travels north-northeast with Inosuke and Zenitsu on their next mission. They reach Natagumo Mountain, where a spider horde resides.
With their fellow Demon Slayers under the demon spider's control, Tanjiro and Inosuke must figure a way to subdue their comrades without harming them.
After facing the mother spider, Tanjiro learns of a demon under Muzan Kibutsuji's direct command who may hold the key to turning Nezuko back to human.
While taking on the enraged father spider demon with Inosuke, Tanjiro is flung far away, where he confronts the spider demon, Rui.
Giyu Tomioka, a top-ranked swordsman of the Demon Killing Corps, arrives. Outclassed and in awe of his skills, Inosuke challenges him to a duel.
Tanjiro prepares for the worst when faced with Rui’s spell. But then, the memory of his father dancing the Kagura inspires him to unleash a new move.
Seeing a heavily injured Tanjiro still try to defend Nezuko, Rui is reminded of the one thing he craves and doesn’t have: true family connection.
Tanjiro is dragged before a gathering of the Hashira, the most powerful of Demon Slayer Corps swordsmen, to face judgment.
Despite Ubuyashiki's decision to accept Tanjiro and Nezuko into the Corps, Sanemi tries to draw out Nezuko's demonic bloodthirst.
Tanjiro and other Corps members receive treatment at Shinobu's estate. Two weeks later, he and Inosuke begin training to rebuild their strength.
Tanjiro trains hard to maintain Total Concentration Breathing all day long. Fearing getting left behind, Zenitsu and Inosuke start training again too.
Muzan Kibutsuji summons the lower ranks of demons and gives the sole survivor a task. Tanjiro's Kasugai Crow appears with his new mission.
After a meeting of the nine Hashira, Flame Hashira Kyojuro Rengoku sets out for the Mugen Train to fulfill his next mission.
Tanjiro, Zenitsu and Inosuke meet up with Rengoku, who tells them that the train could come under attack at any moment.
Enmu has them trapped in their dreams, but can Tanjiro and the others awaken before the destruction of their spiritual core?
Tanjiro takes a drastic step to try to wake himself from his dream. Enmu's pawns are still unable to destroy the spiritual cores.
Inosuke, Nezuko, Zenitsu and Rengoku wake up and join Tanjiro in his battle to protect all 200 passengers asleep on the train.
Though deeply injured, Tanjiro breathes a sigh of relief when Rengoku brings him some good news — when suddenly, another enemy appears before them.
Rengoku does everything he can to defeat the enemy without causing any civilian deaths.
Though severely injured, Tanjiro heads to Rengoku's family home to bring them the tragic news.
Now led by Hashira Tengen Uzui, Tanjiro and the others disguise themselves so they can get hired in the Yoshiwara district.
Inosuke decides to sneak into Makio's room. Meanwhile, Zenitsu hears a little girl crying and tries to help, when he feels an eerie presence behind him.
After his encounter with the powerful demon Daki, Zenitsu disappears. Uzui orders Tanjiro and Inosuke to leave Yoshiwara.
As Uzui searches for Hinatsuru, Tanjiro continues to struggles in his fight against Daki. He decides to attempt a new form of attack.
Tanjiro uses Hinokami Kagura breath to fight back, but Daki regains power when her obi sash escapes the demon's nest and returns to her.
With Nezuko in her demonic form, Tanjiro tries desperately to stop her from attacking an injured woman when Daki reappears, even angrier than before.
Tanjiro, Inosuke and the sleeping Zenitsu rush to Uzui's side, but he's growing weaker from the powerful poison to which he's been exposed.
Gyutaro evades Uzui and goes after Hinatsuru. Tanjiro and Uzui rush to save her, but Daki's obi blocks their way.
Tanjiro wakes up to find himself surrounded by burning debris, with Gyutaro laughing delightedly at his plight.
Despite his seeming defeat, Gyutaro is still able to unleash devastating damage upon the entire district. Tanjiro searches for his friends.
The first deaths of Upper Rank Demons in over a century cause a stir among the demons. Later, Tanjiro goes to Swordsmith Village to get a new sword.
After encountering the aloof Mist Hashira Muichiro Tokito, Tanjiro learns about a special mechanical doll that can be used for combat training.
Tanjiro and Kotetsu inspect the old sword that was inside the Yoriichi Type Zero and discover that it is rusted. Haganezuka offers to restore it.
Kotetsu begs Muichiro to save Haganezuka and Kanamori. Meanwhile, Tanjiro and the others battle the manifestations of Hantengu's emotions.
Mitsuri arrives at the village and finds the chief in a grisly life-or-death situation. Muichiro encounters a formidable enemy blocking his path.
Sensing that a fifth demon is hiding nearby, Tanjiro urges Genya to hunt it down while he and Nezuko contend with the other four foes.
A hateful enemy suddenly appears behind Tanjiro as he strikes the tiny demon. Gyokko enters the shack where Haganezuka is honing the ancient blade.
As he faces several fish demons, Muichiro suddenly recalls the tragedy of losing his parents as a child and the twin brother who treated him coldly.
Muichiro battles with the slippery Gyokko, who unleashes his true form and a terrifying attack. Tanjiro’s group struggles against the five-headed foe.
In a bid to rescue Nezuko and Genya, Mitsuri launches a nimble assault against the demon. Failing to land a decisive blow, she recalls her childhood.
With dawn rapidly approaching, Tanjiro is faced with a difficult dilemma: continue chasing Hantengu's main body, or protect Nezuko from the sun.
The Hashira hold a meeting at Ubuyashiki Mansion while Tanjiro recovers. Later, they devise a training plan for the entire Demon Slayer Corps.
Tanjiro visits Giyu and persistently asks him to train him. Reaching the limits of his patience, Giyu reveals why he refuses to train Tanjiro.
A recuperated Tanjiro heads to his first training course. After a joyful reunion with former Hashira Uzui, he joins in some strenuous exercises.
After arriving at Muichiro's residence, Tanjiro learns that his fellow swordsmen are disheartened by Muichiro's tough training and harsh words.
After doing some flexibility exercises with Mitsuri, Tanjiro goes to train with an angry Iguro, who aims to improve Tanjiro's precision with a sword.
Zenitsu and Tanjiro reunite with Inosuke and Murata at Himejima's training grounds, where they must face brutal tests of endurance and strength.
Tanjiro collapses in exhaustion after moving the boulder. Impressed by Tanjiro's attitude, Himejima opens up about how he raised orphans in a temple.
Kagaya finally comes face to face with Muzan Kibutsuji. Alerted to an attack, the Hashira and Tanjiro hurry toward the Ubuyashiki residence.
