An Upper Rank Demon has been defeated for the first time in a hundred years by Uzui, Tanjiro and his comrades' effort. This news causes a ripple effect not only among the members of the Demon Slayer Corps, but also the Upper Rank Demons, who have been summoned by Muzan Kibutsuji. Meanwhile, Tanjiro is recovering at the Butterfly Mansion when he discovers that he has upset his swordsmith Haganezuka after chipping his sword and decides to head to the village where the swordsmiths live to talk to him in person.
and throughout my life, I was unable
to do what I was supposed to do.
وخلال حياتي، كنتُ عاجزًا عن فعل 
.ما وجب عليّ فعله
Dabei lief ich mein ganzes Leben lang
vor meinen eigenen Pflichten davon.
ni llevar a cabo nada de lo que debía
realizar en la vida.
No hice lo que debía hacer.
et j’ai failli dans toutes les tâches
qui m’incombaient.
और जीवनभर, मैं वह नहीं कर पाया
 जो मुझे करना चाहिए था।
Nella mia vita, non sono riuscito 
a compiere il mio dovere.
e pela minha vida fui
incapaz de fazer o que devia.
Не добился того…
чему посвятил свою жизнь.
