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...
No, no, I would've sensed it
if there'd been any animosity!
لا، لا. كنتُ لأشعر بك لو كنتَ 
!تُضمر أيّ عداء
Nur weil ich wusste,
dass du’s nicht böse meinst!
No. Si hubiera sido un enemigo,
claro que me habría dado cuenta.
Me daría cuenta si tuvieras
intención de hacerme daño.
Non, j’aurais senti
si tu avais de mauvaises intentions.
नहीं, मुझे पता चाल जाता
अगर तुम मुझे क्षति पहुँचाना चाहते!
Ma no, ma no, me ne accorgo molto prima
se sento intenzioni ostili!
Não, não. Eu teria sentido 
se tivesse alguma animosidade.
Ерунда! Будь рядом враг,
я бы сразу вскочил!
