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...
My wounds still haven't fully healed,
and I can't stop my tears from flowing!
،ما زالت جراحي لم تشفَ بعد
!ولا أستطيع إيقاف دموعي
Außerdem bin ich ständig am Flennen,
weil meine Wunden immer noch wehtun!
¡Se me salen las lágrimas
porque todavía no me recuperé del todo!
¡Aún se me saltan las lágrimas
porque no se me han curado las heridas!
Mes blessures sont toujours pas refermées.
J’en chiale encore !
E per di più,
Meus ferimentos ainda não sararam por completo,
 e não consigo fazer minhas lágrimas pararem.
Чтоб ты знал,
