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.
I failed to protect anything
that was important to me,
،فشلت في حماية كلّ ما هو عزيز عليّ
Nichts von dem, was mir teuer war,
konnte ich verteidigen.
Soy alguien que no pudo proteger
nada que considerase preciado
No logré proteger a aquellos
que más me importaban.
Je n’ai pas su protéger
ceux qui m’étaient chers,
मैं हर उस चीज़ को बचाने में
नाकाम रहा, जो मेरे लिए मायने रखती थी,
Non sono riuscito a proteggere niente 
di ciò che è per me importante.
Eu não fui capaz de proteger nada
que era importante para mim,
Я не смог защитить ничего
из того, чем дорожил.
