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 after a demon attack.

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.

Sakonji Urokodaki starts training Tanjiro for Final Selection, the test for joining the unit. 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 captured demons have been imprisoned. Armed with two years worth of training from Sakonji Urokodaki, Tanjiro slashes demon after demon.

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.

Tanjiro is now clad in the uniform of the Demon Slayer Corps. He heads out for his first assignment. A town to the northwest where girls have been vanishing nightly.

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.

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.

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.

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."

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.

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.

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 desperately fights on, but he is overwhelmed by Kyogai's Blood Demon Art.

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…

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.

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.

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 the forest.

Tanjiro and Inosuke face off against the Father Spider Demon of Mt. Natagumo. Tanjiro attacks, 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.

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, challenges Giyu to a duel.

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.

Seeing Tanjiro try to protect Nezuko even as he collapses triggers memories of Rui’s own past. Once a sickly boy, he was turned into a demon by Muzan Kibutsuji. But after becoming a demon, his own parents tried to kill him.

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.

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 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.

Tanjiro, who’s undergoing rehabilitation training at the Butterfly Mansion, works hard to keep up his Total Concentration Breathing techniques all day long.
