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. According to Kotetsu, the key is used to operate a battle-type Mechanical Doll, Yoriichi Type Zero, that mimics the movement of a certain real-life swordsman...
But that's who you are, Tanjiro...
...ولكن هذه طبيعتك يا تانجيرو-سان
No quiero que ese Tanjiro
tan bondadoso muera.
Pero precisamente porque es así
no quiero que muera.
Mais c’est justement pour ça
que je ne veux pas que tu meures.
Mas é assim que você é, Tanjiro.
Но как раз поэтому я хочу,
чтобы вы жили!
