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...
You're summoning me, a demon...
...تستدعيني أنا، مع أنّي شيطانة
Ich, ein Teufel
¿Me invitan a mí, una demonio,
Pese a que soy un demonio,
Moi, un démon,
Vogliono che io, un demone,
Você está chamando um demônio, como eu,
Меня, демоницу…
в самое сердце их организации?
