The Hashira, Sanemi and Iguro, along with their comrades head to an abandoned castle on top of a mountain for a mission, while Tanjiro is being treated at the Butterfly Mansion for the wounds he suffered at the Swordsmith Village. Later on, the Hashira gather at the Ubuyashiki Mansion to hold a Hashira meeting, where Muichiro reveals how the marks manifested. In an effort to strengthen the entire Demon Slayer Corps from the bottom up, the Hashira Training begins...
I finally get back from my mission,
and now we have to train.
،عدت أخيرًا من مهمّتي
.وعلينا الآن أن نتدرّب
Por fin vuelvo de la misión
Je rentre à peine de mission,
Eu finalmente voltei da minha 
missão e agora temos treinamento?
Я-то радовался, что задание позади,
но нет, пора на тренировку.
