Yoriichi Type Zero is destroyed at the end of Tanjiro's training, but a sword from over 300 years ago appears from inside. Kotetsu gives Tanjiro the sword, however it is badly rusted. At that moment, Haganezuka appears and takes the sword with him to perform a grueling whetting process handed down within his family line. Meanwhile the presence of demons are inching closer to the village...
This demon doesn't care about
being decapitated.
.لا يأبه هذا الشّيطان إن قطعنا عنقه
A estos demonios no les preocupa
que les cortemos la cabeza.
A estos les da igual
que les corten la cabeza,
Ils ne craignent pas
d’avoir la tête tranchée.
इस राक्षस को सिर कटवाने की परवाह नहीं है।
A questi demoni non importa di essere decapitati...
Este demônio não se 
importa em ser decapitado.
Попадания по ней
их нисколько не тревожат.
