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.
The thought that you might've perished
made my heart sing—
إنّ فكرة أنّك اقتربت من حتفك
—دفعت قلبي للغناء
Bei dem Gedanken, Ihr könntet besiegt
worden sein, ist mir richtig das Herz auf…
Me saltó el corazón al imaginarme que
quizá fue usted al que habían derrotado.
Creía que lo habían derrotado,
Si c’était vous qui aviez été tué,
इस ख़्याल से कि तुम कहीं मारे नहीं गए हो,
मेरा दिल गाने—
Al solo pensiero che potessero averti fatto fuori, 
il mio cuore saltava di gioi—
Meu coração saltitou de alegria ao pensar
que poderia ter sido você que foi derrotado.
Я уж думал, что вас сразили,
и чуть было не пустился в пляс…
