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...
However, as he himself seemed unable
to describe exactly how his mark appeared...
ولكن، بما أنّه هو بنفسه لا يبدو قادرًا
...على وصف كيف ظهرت العلامة بالضّبط
Doch schien er auch selbst nicht zu wissen,
Pero él tampoco conoce a ciencia cierta
la manera de que aparezca.
Él no parecía ser consciente
de cómo surgieron,
Tuttavia, lui stesso
No entanto, ele parece incapaz de descrever 
exatamente como a marca dele apareceu...
Однако юноше не удалось внятно
объяснить, каким образом она появилась.
