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...
but if I send them like this to the next Hashira,
they're gonna lay all the blame on me.
،لكن إن أرسلتهم هكذا للهاشيرا التّالي
.فسيضع كلّ اللّوم عليّ
aber wenn ich sie so auf die Säulen loslasse,
dann krieg ich von denen den Kopf gewaschen!
pero si los envío así con los otros,
a mí es a quien culparán.
pero si los envío al siguiente Pilar,
mais si je les envoie en l’état
chez les piliers,
Ma se li mando dal prossimo Pilastro 
in questo stato,
mas se eu mandar eles assim para os 
Hashira, vão colocar toda a culpa em mim.
но если я таких тюфяков отправлю к другим
столпам, то сам же крайним и окажусь.
แต่ขืนส่งเจ้าพวกนี้ให้เสาหลักคนต่อไปในสภาพนี้...
