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...
Your demon form is advancing, so stop it!
!ستدخلين هيئة الشّيطان الكاملة، لذلك توقّفي
Sonst verwandelst du dich noch!
¡Eso acelera tu estado demoníaco!
Ça accélère la propagation.
तुम संपूर्ण राक्षस रूप से लोगी,
इसलिए रुक जाओ!
Rischi di diventare in tutto
 e per tutto un demone, fermati!
Você vai ficar em forma 
completa de demônio! Pare!
Не превращайся дальше!
