In the Taisho era of Japan, young Tanjiro Kamado's life is forever altered when he returns from a charcoal-selling excursion to find his family brutally slaughtered by a demon. Amidst the carnage, he discovers that his sister, Nezuko, has survived the attack, but at a terrible cost—she has been transformed into a demon herself. Grappling with this heart-wrenching reality, Tanjiro resolves to become a demon slayer, dedicating himself to the twin goals of restoring Nezuko's humanity and exacting vengeance upon the demon responsible for his family's massacre. Tanjiro's path is one of unimaginable challenges and hardships. As the sole breadwinner for his impoverished family following his father's death, he had shouldered the burden of supporting them while living a humble life in the remote mountains. The devastating loss of his loved ones and Nezuko's tragic fate fuel his determination to master the ways of the demon slayer. Joining forces with the enigmatic Demon Slayer Corps, Tanjiro embarks on a perilous journey, driven by an unwavering commitment to protect the remnants of Nezuko's humanity and rid the world of the malevolent demons that plague it. Through his trials and tribulations, he must confront not only the demons that lurk in the shadows but also the depths of his own grief, rage, and the unbreakable bonds of family.
