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...
The training by the currently active Hashira
will be even harsher than this!
سيكون التّدريب تحت الهاشيرا
!الحاليّين أصعب بكثير من هذا
Mit den aktiven Säulen zu trainieren,
wird euch noch mehr abverlangen!
El entrenamiento de los Pilares activos
que sigue después es aún peor.
El entrenamiento de los Pilares
actuales será más duro.
Les sessions avec les piliers
seront bien plus intenses.
Gli allenamenti con i Pilastri 
saranno ben più duri di questo!
O treinamento dos Hashira em atividade 
vai ser muito pior que isso.
Нынешние столпы
приготовили испытания куда сложнее!
การสั่งสอนจากเสาหลักตัวจริงมันโหดหินกว่านี้อีกนะ
