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...
It's never broken down
in all that time? That doll?
لم تُكسر تلك الدّمية طوال ذلك الوقت؟
Und diese ganze Zeit hat die Puppe
unbeschadet überstanden?
¿El muñeco no se ha descompuesto
en todo ese tiempo?
¿Y el autómata no se ha roto
en todo ese tiempo?
Et depuis tout ce temps,
l’automate ne s’est pas cassé ?
इतने समय में भी वह ख़राब नहीं हुआ?
वह पुतला?
E in tutto questo tempo
non si è mai rotta?
Esse boneco nunca quebrou 
em todos esses anos?
И за все эти годы боевая кукла
так и не сломалась?
