Tanjiro's wounds have healed, so he first visits the former Hashira, Uzui, to join the Hashira Training. Tanjiro's joy for the reunion with Uzui is short-lived, however, as he will now undergo basic training to boost his physical stamina.
Or I won't be able
to keep my promise to the Master!
!وإلاّ فلن أستطيع الوفاء بوعدي للمعلّم
Ich habe es Oyakata-sama versprochen!
Debo cumplir la promesa
que le hice al comandante general
o incumpliré la promesa al patrón.
J’ai fait une promesse
à maître Ubuyashiki !
Devo mantenere la promessa col capofamiglia!
Ou eu não vou conseguir manter 
minha promessa com o mestre!
Иначе мне не сдержать слово,
данное главе!
