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...
That's right. We're going to train
under every Hashira one by one!
هذا صحيح. سنتدرّب على يد كلّ
!هاشيرا واحدًا تلو الآخر
Ja. Wir sollen der Reihe nach
mit jeder einzelnen Säule trainieren!
Sí, dicen que iremos en orden
para que cada Pilar nos entrene.
Sí. Iremos con los Pilares por turnos
para que nos entrenen.
Oui. Les piliers vont se relayer
pour nous entraîner !
Sì, esatto. I Pilastri ci alleneranno a turno.
É mesmo... Nós vamos treinar 
com cada um dos Hashira!
Конечно. Говорят, нас там будут
все столпы учить по очереди.
