Read the Demon Slayer Manga


Tanjiro Kamado becomes a demon slayer to avenge his family and protect his demon sister. Together with his allies, they face off against powerful demons and unlock new abilities. They also ally with Tamayo and Yushiro to develop a cure for Nezuko, which requires them to fight the most powerful demons. The story culminates in a final battle against Muzan, the most powerful demon, where they defeat the remaining Kizuki members and trap Muzan with a poison to reach him. Tanjiro fights against Muzan, who seeks to become the ultimate being.


The story takes place in Taishō era Japan, where a secret society, known as the Demon Slayer Corps, has been waging a secret war against demons for centuries. The demons are former humans who were turned into demons by Muzan Kibutsuji injecting them with his own blood, and they feed on humans and possess supernatural abilities such as super strength, powers that demons can obtain called “Blood Demon Art,” and regeneration. Demons can only be killed if they are decapitated with weapons crafted from an alloy known as Nichirin, injected with poison extracted from wisteria flowers, or exposed to sunlight.

The Demon Slayers, on the other hand, are entirely human, but they employ special elemental breathing techniques, known as “Breathing Styles,” which grant them superhuman strength and increased resistance, helping them fight against demons. The strongest Demon Slayers are known as the Hashira, and gain this rank through either killing a member of the Twelve Kizuki or killing fifty demons after ranking up multiple times.

Tanjiro Kamado is a kind-hearted and intelligent boy who lives with his family in the mountains. He became his family’s breadwinner after his father’s death, making trips to the nearby village to sell charcoal. One day, when he returns home, he discovers that his family was attacked and slaughtered by a demon. Tanjiro and his sister Neya, and Mitsuri Kanroji are killed in the process. In the final battle, Tanjiro and the remaining Hashira fight against Muzan, who has transformed into a monstrous form. Tanjiro, armed with his Hinokami Kagura and a newly crafted Nichirin sword, unleashes a powerful attack that cuts off Muzan’s head, finally defeating him and ending the war against the demons.

However, the victory comes at a heavy cost. Many members of the Demon Slayer Corps have lost their lives, including some of Tanjiro’s closest friends. Tanjiro himself is gravely injured and has sustained severe burns from using his Hinokami Kagura. Nezuko, who has finally been cured of her demon curse, uses her newly acquired Blood Demon Art to protect her brother from further harm. Tanjiro and his friends are taken to a hidden village for recovery, where they are aided by a new set of characters, including Kiriya Ubuyashiki, the younger brother of the late Kagaya, who takes over as the leader of the Demon Slayer Corps.

The story ends with Tanjiro and his friends returning to their normal lives, with the memories of their struggles and triumphs serving as a reminder of the sacrifices they made to protect humanity. The final scene shows Tanjiro and Nezuko visiting their family’s graves, where they reflect on the lessons they have learned and the bonds they have formed with their comrades in the Demon Slayer Corps.

Throughout the series, themes of family, love, and sacrifice are explored, as Tanjiro’s unwavering devotion to his sister and his determination to avenge his family drive him to become a hero in a world filled with darkness and despair. The story is also filled with action, humor, and heartwarming moments that make it a beloved and memorable anime for fans of all ages.
