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...
Can the training be handled
by just us active Hashira?
هل يمكن إدارة التّداريب من
طرفنا نحن الهاشيرا الحاليّين فقط؟
Sind wir aktiven Säulen denn genug,
um das Training durchzuführen?
¿Sera suficiente con que los Pilares
en activo lo llevemos a cabo?
¿Habrá suficientes instructores
con los Pilares actuales?
Pourra-t-on entraîner tout le monde
à nous seuls ?
Basteremo noi Pilastri 
attualmente in attività?
Só nós, os Hashira ativos, seremos 
suficientes para este treinamento?
А хватит ли действующих столпов
для масштабных занятий?
