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...
He came without making a sound.
That's what a swordsman can do.
.أتى دون إحداث أيّ صوت
.هذا ما هو قادر عليه السّيّافون
Er ist hier lautlos hochgekommen …
Schwertkämpfer sind unglaublich …
Subió sin hacer ruidos.
Es un verdadero espadachín.
Ha venido sin hacer ruido.
Il est monté sans un bruit.
C’est un vrai pourfendeur.
वह बिना आवाज़ किए आया।
तलवारबाज़ यही कर सकता है।
È arrivato fin qui senza fare alcun rumore!
Ele veio sem fazer barulho. É 
isso que um espadachim pode fazer.
Поднялся беззвучно.
Настоящий мечник!
