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...
That was totally your own fault
for hitting a girl, Genya.
.كان ذلك خطأك بالكامل لأنّك ضربت فتاة يا غينيا
Aber Genya, du hast ein kleines Mädchen
geschlagen. Da hatte ich keine Wahl.
Tú tuviste toda la culpa por pegarle
a la niña. No tuve otra opción.
Pero eso fue porque pegaste
a una niña, Genya.
C’était ta faute, Gen’ya.
Tu avais frappé une fille.
उस लड़की को छेड़कर
तुमने ही ग़लती की थी, गेन्या।
Hai colpito una ragazza, 
quindi eri palesemente nel torto, Genya.
Aquilo foi sua culpa por 
bater em uma menina, Genya.
Тогда ты поднял руку на девушку
и получил по заслугам, Гэнъя.
