Tanjiro and Zenitsu head to Himejima's training site deep in the mountains and reunite with Inosuke and Murata. Tanjiro first starts the training by being hit by a waterfall but struggles with the coldness and weight of the water.
I never knew that boulders were this warm!
!لم أعلم أبدًا أنّ الجلاميد كانت بهذا الدّفء
No sabía que eran así de calientes.
No sabía que fueran tan calentitas.
J’ignorais que la roche réchauffait.
Sono sempre state così calde?
Nunca imaginei que rochas 
fossem ser tão quentinhas!
