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 strongest will gather and give training...
...سيجتمع أشخاص أقوياء وسيدرّبوننا
Irgendwelche starken Kerle sollen
herkommen, um hier Arschtritte zu verteilen!
Que todos los tipos fuertes se juntarán
pa' entrenarnos.
Vamos a practicar con los más fuertes
Les balèzes
vont nous entraîner ensemble.
I più forti si riuniranno per allenarci!
Сильные мечники соберутся нас обучать.
เอาพวกที่แข็งแกร่งมารวมกันแล้วก็สั่งสอน...
