Tanjiro encounters Mist Hashira Muichiro Tokito and Kotetsu, a boy from the village, arguing. Muichiro is demanding that a "certain key" be handed over to him from Kotetsu. Being unable to look on in silence, Tanjiro intervenes to speak on behalf of Kotetsu, however Muichiro refuses to listen.

But I have faith that someone
will surely finish the job for me.
.لكنّي أؤمن أنّ شخصًا ما سيُنهي عملي بكلّ تأكيد

कि कोई मेरा यह काम पूरा कर देगा।
Ma sono convinto
Mas eu sei que alguém vai 
terminar isso para mim.
