Kimetsu no Yaiba

Tanjiro Kamado lives a modest but happy life in the mountains, supporting his mother and younger siblings by selling charcoal. One winter night changes everything. Returning home after being delayed in the village, he finds his family slaughtered by a demon, with only his sister Nezuko still alive. She has been transformed into a demon herself, yet flashes of her human affection remain. Refusing to abandon her, Tanjiro sets out to learn how to fight the creatures responsible and search for a way to make Nezuko human again. His journey leads him into the Demon Slayer Corps, where every battle brings him closer to the truth behind his family's destruction.
