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...
A demon showed up while Mr. Haganezuka
was working on your sword,
ظهر شيطان بينما يعمل 
،هاغانزوكا-سان على سيفك
Jetzt ist dieser Teufel aufgetaucht, während
Haganezuka-san dein Schwert bearbeitet.
Los demonios atacaron cuando Haganezuka
trabajaba en la espada. ¿Va todo bien?
Han venido demonios
mientras Haganezuka tiene tu katana.
On a donné le sabre juste avant
d’être attaqués. Tu vas t’en sortir ?
एक राक्षस आ गया जबकि श्री हागानेज़ुका
तुम्हारी तलवार बना रहे थे,
Al villaggio sono arrivati i demoni mentre 
la tua katana era nelle mani di Haganezuka-san...
Um demônio apareceu quando o Sr. Haganezuka 
estava trabalhando na sua espada,
Ты не пострадал от того, что перед
нападением демона отдал меч Хаганэдзуке?
