Iku-shu Urokodaki Sakonji (育手・鱗滝左近次)
At Giyu Tomioka's urging, Tanjiro heads for Mt. Sagiri with Nezuko who's been turned into a demon. During the night, Tanjiro catches the smell of blood from inside a temple. He enters, thinking that someone might be hurt, only to come upon a demon.
It is the Taisho Period in Japan. Tanjiro, a kindhearted boy who sells charcoal for a living, finds his family slaughtered by a demon. To make matters worse, his younger sister Nezuko, the sole survivor, has been transformed into a demon herself. Though devastated by this grim reality, Tanjiro resolves to become a “demon slayer” so that he can turn his sister back into a human, and kill the demon that massacred his family. A sorrowful tale of siblings in which the fates of humans and demons intertwine… begins now!
