Looking back on the precious smile Nezuko gave him as she saw him off, it breaks your heart to think of the tragedy that soon follows 😢.
A Kind-Hearted Boy and His Day in the Village
Arriving at the village, Tanjiro shows his characteristic kindness by helping out the locals. Blessed with an extraordinarily keen sense of smell, he even pinpoints the culprit behind a broken dish just by scent. As night falls, a villager insists that Tanjiro stay overnight. An old man named Saburo warns him that man-eating demons roam the mountain after dark. Tanjiro stays at Saburo’s house, but his mind remains filled with thoughts of his family.
The Onset of Tragedy and a Cruel Fate
Early the next morning, Tanjiro sets off for home. Along the mountain path, he suddenly catches the scent of blood, and a wave of dread washes over him. Arriving at the house, he is greeted by a sight beyond nightmare… His family has been brutally slaughtered in an attack by a Demon (Oni), leaving their home covered in blood and utterly devastated. Grief-stricken, Tanjiro desperately checks on his family and realizes that his sister Nezuko is still warm. Clinging to a single ray of hope, he carries Nezuko on his back and sprints down the mountain 😭.

Fateful Encounter with Giyu Tomioka

His desperate, tearful pleas convey the unbearable pain of losing his family and his ultimate refusal to lose his sister, too 😭💔.
Human Bond: Nezuko Awakens
