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...

.غادر بعد أن سلّمته المفتاح
Er ist weg, als ich ihm
den Schlüssel gegeben hatte.
Se fue después de que le diera la llave.
Le he dado la llave y se ha ido.
Je lui ai remis la clé,
et il est parti…
मैंने उसे चाबी दे दी, इसलिए वह चला गया।
Gli ho dato la chiave e se n'è andato.
Eu entreguei a chave, então ele já foi.
