Demon Slayer: Kimetsu no Yaiba

It is the Taisho Period. Tanjiro Kamado is living a modest but blissful life in the mountains with his family. One day, when he returns from selling charcoal in town, he finds his family slaughtered in pools of blood after a demon attack. Tanjiro rushes down the snowy mountain with the sole survivor, his sister Nezuko, on his back. But on the way, Nezuko suddenly snarls, turning on Tanjiro

At Giyu Tomioka's urging, Tanjiro heads for Mt. Sagiri with his sister Nezuko who's been turned into a demon. During the night, Tanjiro catches the smell of blood from inside a temple. He enters, thinking that someone might be hurt, only to come upon a man-eating demon. When the demon attacks, Tanjiro manages to fight back with his hatchet, but the demon's strength is overwhelming. Just as the demon is about to finish him off, Tanjiro is saved by none other than...

The Demon Slayer Corps... An organization that's been hunting down demons since ancient times. Sakonji Urokodaki starts training Tanjiro for Final Selection, the test for joining the unit. Navigating a mountain riddled with booby traps, dry sword swings, waterfall immersion and breathing techniques... A year later, Urokodaki informs Tanjiro that he has nothing more to teach him, and gives him one last hurdle to overcome in front of a giant boulder.

To pass Final Selection, one must survive for seven days on Mt. Fujikasane where demons captured by the Demon Slayers have been imprisoned. So begins the battle for survival between the young swordsmen and the demons. Armed with the breathing techniques and stances he'd learned from Sakonji Urokodaki, Tanjiro slashes demon after demon. His two years of training have not gone to waste. But just then, a morphed demon appears out of nowhere.

When day breaks, there are only four swordsmen left standing after the seven-day battle. The guides who greet Tanjiro and the other survivors explain the Demon Slayer Corps system. All four are issued uniforms and Kasugai Crows as messengers, after which they must select the ore for their own Nichirin Swords. After gazing hard at each lump of ore and using his sense of smell, the one Tanjiro chooses is...

Tanjiro is now clad in the uniform of the Demon Slayer Corps. His Nichirin Sword on his hip, and Nezuko, now awake, in a special box made by Urokodaki on his back, he heads out for his first assignment. A town to the northwest where girls have been vanishing nightly. There, Tanjiro meets Kazumi, haggard with worry after his girlfriend's been abducted. Though he does catch the scent of a demon nearby, there's just no demon in sight. Tanjiro is sure that a demon is behind this sinister incident...

Now split into three, the demons have driven Tanjiro into a corner. It is then that Nezuko attacks. Now that she's become a demon herself, she's no longer so weak that she needs protection. His mind made up, Tanjiro follows one of the demons into the swamp now spreading across the ground. Waiting for him there is...

The next mission is in Asakusa, Tokyo. Tanjiro is taken aback by the opulent Taisho Era cityscape, but soon picks up the demon's scent there. His pursuit of the scent leads him to Muzan Kibutsuji. Tanjiro attempts to strike him down. But Kibutsuji transforms a passerby into demon, triggering a commotion. As Tanjiro desperately tries to get things under control, someone appears before him..

It was two demons named Tamayo and Yushiro who came to Tanjiro's rescue. Using the "Eyeblind" spell, Tamayo guides Tanjiro and Nezuko to her house. There, through his conversation with Tamayo, Tanjiro learns that there is a way to return demons to human form. Just then, two demons in pursuit of Tanjiro locate the house and unleash a furious assault...

Tanjiro's crisis continues. He uses multiple forms of the Water Breathing technique to hold out against Yahaba's final Blood Demon Art, the "Kouketsu Arrow." Meanwhile, Nezuko and Susamaru are still battling it out. Worried about the outcome, Tamayo unleashes her own Blood Demon Art.

Tanjiro's next destination, according to his Kasugai Crow, is to the south-southeast. On the way, Tanjiro runs into his fellow Final Selection survivor, the swordsman Zenitsu Agatsuma. Tanjiro has a hard time dealing with Zenitsu's passive attitude as they head deep into the mountains. They encounter two children whose older brother was taken away right in front of their house. There, Zenitsu hears the sound of a tsuzumi ringing out from somewhere.

Inside the house, where the rooms spin each time the tsuzumi is played, Tanjiro gets separated from Zenitsu Agatsuma. Without Tanjiro by his side, Zenitsu is overcome by fear and despair as he takes Shoichi through the house. Meanwhile, Tanjiro meets the master of the house, the tsuzumi-playing demon, and an odd-looking man wearing a boar's head mask.

Every time Kyogai, the master of house, plays his tsuzumi, the room spins and Tanjiro struggles. Debilitated by the fractured bones he sustained in his previous battle, Tanjiro tries to fire himself up as he desperately fights on, but he is overwhelmed by Kyogai's Blood Demon Art. Will he find a way to slice off Kyogai's head?

After a desperate fight to the death, Tanjiro prevails over Kyogai. He exits the house to find Zenitsu who had escaped earlier. But it is then that he sees the strange circumstances before him... The battered Zenitsu holding the box containing Nezuko in his arms while the man in the boar's head mask stands in the way with two Nichirin Swords drawn.

Their next destination is to the north-northwest. Tanjiro and Nezuko head towards Mount Natagumo with Zenitsu and Inosuke. This mountain is covered with spider webs and is swarming with innumerable spiders. Leaving the cowering Zenitsu behind, Tanjiro and Inosuke head up the mountain where they run into fellow Demon Slayers entangled in spider webs.

Tanjiro and Inosuke battle the Demon Slayers trapped by spider webs. After slashing the threads and destroying the webs, they head deeper into the mountain. The farther they advance through the forest, the thicker the threads become, and those under their control start moving in ways impossible for a human being. Stopping the Demon Slayers without hurting them isn't going to be easy, but then Tanjiro makes a certain move...

One of the Twelve Kizuki, a direct subordinate of Muzan Kibutsuji, is here somewhere. When Tanjiro slays the Mother Spider Demon of Mt. Natagumo, he learns that a demon who might hold the key to turning Nezuko back into a human is somewhere in this very forest. With the battered Inosuke in tow, he heads deeper into the forest. Meanwhile, Zenitsu trudges forlornly through the woods only to encounter a spider with a human face

Tanjiro and Inosuke face off against the Father Spider Demon of Mt. Natagumo. Tanjiro unleashes an attack, only to get hurled away by the demon's overwhelming power. Landing near a river, he comes upon the young demon Rui torturing the Sister Spider Demon. When Rui calls their bond of terror and hatred "a family's bond," Tanjiro is enraged. So begins the battle between Rui and Tanjiro.

Swordsmen in the Demon Slayer Corps known as Hashiras have arrived on Mt. Natagumo. Giyu Tomioka, the Water Hashira, slays the Father Spider Demon with a single strike. Inosuke, thrilled to see such a display of swordsmanship by someone in a totally different league from himself, challenges Giyu to a duel. Meanwhile, Zenitsu lies near death as the poison circulates throughout his body. Just then, the Insect Hashira, Shinobu Kocho appears before him.

When Rui assaults him with his Blood Demon Art, Tanjiro braces himself for certain death. As his life flashes before his eyes, he suddenly remembers his father's dance, the kagura, and unleashes a new, non-Water Breathing attack. Hinokami Kagura Dance. Knowing that he'll be receiving a simultaneous blow from the demon, he uses his new move to slice off Rui's head. As Tanjiro crawls towards Nezuko, who lies on the ground, riddled with wounds, someone appears before him.

Seeing Tanjiro try to protect Nezuko even as he collapses triggers memories of Rui's own past. Once a sickly boy, he became a demon after meeting Muzan Kibutsuji who gave him a share of his blood. But after he turns into a demon, his own parents try to kill him. Ever since then, he has been searching for a family. Seeking a bond that he can never hope to acquire..

After the battle is over, Tanjiro and Nezuko are taken to the Demon Slayer Corps headquarters. This is where the Hashira Meeting between the Corps leader, Ubuyashiki, and the Hashiras, the most powerful swordsmen in the Corps, is to be held. The Hashiras censure Tanjiro for violating the Demon Slayer Corps by protecting a demon. And then, the Wind Hashira, Sanemi Shinazugawa, raises his sword against Nezuko...

Ubuyashiki, the leader of the Demon Slayer Corps, finally appears before Tanjiro. He tells him that he will allow Tanjiro and Nezuko to join the Corps. But the Hashiras are unable to accept this decision right away. The Wind Hashira, Sanemi Shinazugawa, slashes his own arm and taunts Nezuko with his blood, trying to get her to show her true colors as a demon

The injured Tanjiro, Zenitsu and Inosuke are sent to the home of the Insect Hashira, Shinobu Kocho, for treatment. Two weeks later, Tanjiro and Inosuke start rehabilitation training. But the drills are brutal, and they find themselves broken in spirit. Unaware of the grueling regimen, Zenitsu joins them late and is visibly enthusiastic in front of girls, but...

Tanjiro, who's undergoing rehabilitation training at the Butterfly Mansion, works hard to keep up his Total Concentration Breathing techniques all day long. Though at first, he's helpless against Kanao, a swordswoman in his class who's training him, he slowly but surely begins to make some headway. Seeing Tanjiro devote himself to training every single day, Zenitsu and Inosuke resume training as well, but..

As Tanjiro and the others are devoted to their rehabilitation training, the absolute master of the demons, Muzan Kibutsuji, gathers the Lower Ranks of the Twelve Kizuki. The demons, too, are preparing to make their next move. As training draws to a close, Tanjiro has improved to the point where he can fight on equal terms with Kanao. Just then, he receives word of a new mission from his Kasugai Crow.

Flame Hashira Kyojuro Rengoku receives new orders: Travel to the Mugen Train, where over forty people have gone missing, and conduct an investigation. Leaving the Demon Slayer Corps Headquarters, he sets off on this new mission.

Kyojuro Rengoku heads to the Mugen Train to investigate the disappearance of over forty passengers and encounters a demon along the way. After saving the people attacked by the demon, he finally arrives at the Mugen Train. What lies ahead of him?

Trapped in Enmu's spell, Tanjiro, Zenitsu, Inosuke and Kyojuro fall closer and deeper into an eternal slumber. Faced with death, Tanjiro is forced to confront his demons to save them.

With Tanjiro successfully awakening from his dream, he confronts the demon responsible, Lower One Enmu. But the situation challenges Tanjiro's resolve when Enmu proves more powerful that any demon he's ever faced.

The battle with Enmu continues as Inosuke, Zenitsu and Rengoku awaken from the spell. Tanjiro and Inosuke try to pinpoint the demon's weak spot, while the others focus on protecting the passengers in the train.

Tanjiro has finally slashed Enmu's neck with the help of Inosuke. The tremors from the train flipped it over the rails. As silence deepens a mysterious figure approaches from behind.

Akaza continues to offer Rengoku the chance to become a demon to improve his skills. Rengoku refuses his offer and is trying his best to keep up with him. The fire Hashira has one goal:to protect his comrades even if it costs his own life.

After the Mugen Train incident, Akaza visits Muzan Kibutsuji. Guided by a crow, Tanjiro Kamado heads off to the Rengoku residence to convey Kyojuro Rengoku's last messages to his father and little brother. Tanjiro's group return to the Butterfly Mansion.

One day, Tanjiro returns to the Butterfly Mansion and finds Sound Hashira, Tengen Uzui, attempting to take Aoi and Naho away on a mission against their will. Tanjiro, Zenitsu and Inosuke offer to go on that mission instead, and they head to their next destination - the Entertainment District.

After arriving at the Entertainment District, Tanjiro and his comrades infiltrate each House where Uzui's wives, Suma, Makio and Hinatsuru, work. While working as apprentices and searching for their whereabouts, Inosuke hears that Makio has been shutting herself away from everyone in her room.

Realizing Zenitsu is now missing, Tanjiro and Inosuke re-arm and look for signs of the demon. Tanjiro goes in alone and is confronted by Upper Rank Six.

Facing Daki alone, Tanjiro tries to use Hinokami Kagura but is hampered by the extreme stress it causes his body. Inosuke and Tengen locate the demon's victims and meet the demon responsible for abducting Zenitsu and his wives.

Furious at Daki's disregard for lives, Tanjiro angrily confronts her, causing her to experience Muzan's memories of an old enemy. His excessive use of Hinokami Kagura soon brings him to his knees in pain.

As Nezuko rushes to aid Tanjiro during a critical moment, her appearance begins to gradually take on a demon form as she sustains Daki's attacks. Nezuko is able to overpower Daki as her demon form accelerates; however, she turns her attention to innocent bystanders injured during the battle and charges towards them. While Tanjiro attempts to restrain Nezuko, Daki draws near...

Uzui battles furiously, taking on both Daki and the other demon who emerged from her body, Gyutaro. But he's gradually losing strength due to the poison from Gyutaro's scythe. Just then, Inosuke, the sleeping Zenitsu, and Tanjiro, who's managed to get Nezuko to sleep, all come rushing to Uzui's aid...

Hinatsuru's use of wisteria poison leaves Gyutaro momentarily vulnerable, but Tanjiro and Uzui's attacks fall just short. Using his Blood Demon Art, Gyutaro vanishes from Uzui's sight only to reappear assaulting Hinatsuru. Tanjiro and Uzui attempt to save her, but they are thwarted by Daki's Belt.

Amid the wreckage from the buildings destroyed by the destructive attacks of Daki's Belt, Tanjiro awakens. Zenitsu is trapped under the rubble and Inosuke has been impaled by Gyutaro's scythe, while Uzui has lost an arm and his heart has stopped. As Gyutaro taunts Tanjiro by calling him a disgrace, all seems hopeless until...

As the fierce battle draws to an end, Tanjiro and Uzui behead Gyutaro just as Zenitsu and Inosuke behead Daki. But then, Gyutaro unleashes a devastating Blood Demon Art, burying the city in rubble. When Tanjiro awakens, he joins Nezuko and Zenitsu, only to find Inosuke and Uzui on the brink of death from Gyutaro's poison...

After their battle with the Upper Rank Six siblings, Tanjiro, Zenitsu, Inosuke, and Nezuko are found by the Kakushi. In the Infinity Castle, Muzan Kibutsujisummons the remaining five Upper Rank demons – Akaza, Upper Five Gyokko, Upper Four Hantengu, Upper Two Doma and Upper One Kokushibo. He admonishes them for their failure to kill the Ubuyashikis and find the Blue Spider Lily. When Gyokko provides new information, he is sent on a joint mission with Hantengu. While Zenitsu and Inosuke are summoned to individual missions, Tanjiro continues his rehabilitation. When his swordsmith Hotaru Haganezuka refuses to forge him a new sword, Tanjiro is told to meet him at the Swordsmith Village to discuss the matter in person. He arrives with Nezuko and meets the village's chief, Tecchin Tecchikawahara, who reassures Tanjiro he will bring Hotaru back to build the sword. Tanjiro is later shown to the village's hot springs where he meets the Love Hashira Mitsuri Kanroji, who is initially dejected after being ignored by an unknown person. While in the hot springs, Tanjiro encounters Genya, the Wind Hashira Sanemi Shinazugawa's younger brother and fellow Demon Slayer, who refuses Tanjiro's hospitality and storms off. At the village, Mitsuri hints at Tanjiro about a "secret weapon" hidden somewhere that can make him stronger and bids farewell to the siblings. The next day, while searching for the weapon, Tanjiro finds the Mist Hashira Muichiro Tokito in an argument with someone and sees that seemingly with them is a man from his dreams.

While eavesdropping, Tanjiro watches as Muichiro threatens the swordsmith he was arguing with. He tries to defend him but the indifferent Hashira knocks him out for interfering. After waking up, the boy, named Kotetsu, explains that the "man" he saw is actually an advanced mechanical training doll, built after a swordsman who lived over 300 years ago. He explains the doll was made by his ancestors, and as he lacks a family, it is all he has to pass on to the next generation. Tanjiro agrees to protect it, but Muichiro appears, having finished his training session and causing extensive damage. However, after Kotetsu discovers it is still functional, he tells Tanjiro to train with it in order to become stronger than the arrogant Muichiro. However, training proves harsh as Kotetsu denies Tanjiro food and water when he fails to connect hits on the doll. When Tanjiro eventually faints from exhaustion, he imagines himself in the afterlife and sees a peculiar stone in the Sanzu River, enabling him to detect a scent faster than the Opening Thread. He uses this to his advantage, eventually landing a powerful strike on the doll's head, which shatters and reveals a concealed sword inside.

Tanjiro becomes disappointed after he discovers the sword rusted. However, a swole Hagenazuka appears, revealing he trained in solitude to be able to forge a better sword for Tanjiro. As such, he offers to restore the rusty sword, giving Tanjiro another one in the meantime. That night, while trying to befriend Genya, swordsmith Kanamori is brutally devoured by Gyokko who, alongside Hantengu, has found the village. After Muichiro is moved by Tanjiro's sense of kindness towards others, Hantengu enters their room, only to be quickly beheaded. However, two individual demons regenerate from the severed body parts, each with different, powerful abilities. After one of them blasts Muichiro far away, the other nearly electrocutes Tanjiro with a staff, before Genya appears and beheads them both with a sawed-off shotgun and a Nichirin knife. However, Hantengu again duplicates, and one of the demons deafens Tanjiro with a sonic attack while Nezuko tries to defend Genya. Meanwhile, Muichiro runs back to assist, but finds Kotetsu in peril from one of Gyokko's spawn. Initially electing not to help him, he saves him just before being eaten after remembering about the importance of kindness with others.

Muichiro rescues Kotetsu who is being attacked by a goldfish demon; Nezuko and Genya face off against demons; Separated from the others, Tanjiro fights a battle with a demon marked with the word 'Joy'.

Upon arriving, Mitsuri comes to Tecchin, the chief of the village, and finds out all of his guards have been defeated.

Muichiro is trapped in water by Gyokko's Blood Demon Art. Tanjiro and and his comrades have successfully severed the necks off the four demons, but they realize that they cannot be defeated this way.

As Tanjiro was just about to sever the neck of the fifth demon, another demon approaches from behind him. This demon turns out to be Zohakuten, a demon created by combining all four Emotion Demons into one body, marked with the word "Hatred." Tanjiro makes a narrow escape from the attack and fails to sever the neck of the fifth demon. After hearing Zohakuten calling him and his comrades "awful villains" for trying to sever the neck of the cowering demon, Tanjiro is enraged and decides to face him...

With Kotetsu's help, Muichiro finally manages to escape from Gyokko's Blood Demon Art, but he is close to reaching his limit with all of the damage he has sustained. As the goldfish demons draw closer to the battered Muichiro and Kotetsu, Muichiro's memory is awakened the very moment the demons attack. In this memory, he remembers his father, a lumberman, his mother, and his older twin brother, Yuichiro...

After defeating the goldfish demons, Muichiro heads to the studio where Haganezuka and Kanamori are. There, in order to disrupt Haganezuka's focus on whetting the sword, Gyokko was attempting to take Kanamori for hostage. Muichiro arrives in the nick of time, receives the Nichirin Sword from Kanamori, and challenges Gyokko once again...

After rescuing Tanjiro who was swallowed by one of the tree dragons, Mitsuri now faces off against Zohakuten in order to save Nezuko and Genya. Mitsuri skillfully fends off the fierce attacks from the tree dragons, but she is struck with a powerful attack from Zohakuten and loses consciousness right before she is able to land a decisive blow. As a killer blow is about to strike down on her, Mitsuri recalls a memory of her past self and her special constitution...

As Mitsuri holds off Zohakuten, Tanjiro, Nezuko and Genya use this time to chase after Hantengu's main body. The three manage to find the tree ball that Hantengu is hiding in, but when they slice it open, they find that it is completely empty. Hantengu makes a run for it again, and Tanjiro and the others continue chasing him. Seeing Hantengu running about, Genya snaps and hurls a tree at him, and Nezuko jumps at him!

The Hashira, Sanemi and Iguro, along with their comrades head to an abandoned castle on top of a mountain for a mission, while Tanjiro is being treated at the Butterfly Mansion for the wounds he suffered at the Swordsmith Village. Later on, the Hashira gather at the Ubuyashiki Mansion to hold a Hashira meeting, where Muichiro reveals how the marks manifested. In an effort to strengthen the entire Demon Slayer Corps from the bottom up, the Hashira Training begins...

Kagaya's Kasugai Crow suddenly appears in front of Tamayo and invites her to the Demon Slayer headquarters — even though she is a demon. Meanwhile, after receiving a letter from Kagaya at the Butterfly Mansion, Tanjiro pays a visit to Giyu, who is not participating in the Hashira Training. At first, Tanjiro is rejected by Giyu but patiently continues to try to talk to him. Giyu, who gives in to Tanjiro's persistence, begins to share the reason why he won't participate in the training.

Tanjiro's wounds have healed, so he first visits the former Hashira, Uzui, to join the Hashira Training. Tanjiro's joy for the reunion with Uzui is short-lived, however, as he will now undergo basic training to boost his physical stamina.

After completing training with Uzui, Tanjiro visits the Tokito residence next. The Demon Slayer swordsmen who have already started the training are dispirited by Muichiro's intense training and harsh words. Tanjiro hears the swordsmen discussing if there's anything they can do about it...

After completing Mitsuri's training, Tanjiro heads to train with Iguro. When he arrives at the training site, Iguro is waiting for him, visibly angry. Will he be able to complete this horrifying training where he'll have to fix his sword skills?

Tanjiro and Zenitsu head to Himejima's training site deep in the mountains and reunite with Inosuke and Murata. Tanjiro first starts the training by being hit by a waterfall but struggles with the coldness and weight of the water.

During the boulder training, Tanjiro is able to move the boulder thanks to Genya's training advice. However, Tanjiro has used all of his power to do so and he is saved by Himejima after he collapses. Himejima, moved by Tanjiro's genuineness, begins to talk to him about his past...

During a silent night when the moon shines, Kagaya finally meets Muzan Kibutsuji, who appears at the Ubuyashiki Mansion. Kagaya is staying alive day-by-day through his steadfast desire to defeat Muzan, while Muzan dreams of eternity. What will these two, bound by a continuous thousand-year fate, talk about?
