Why did Tanjiro stop Breathing? Tanjiro was too exhausted to perform the Hinokami Kagura and not suited for Water-Breathing, so he desperately combined the two Styles to save Hinatsuru from Gyutaro’s grasp. Breathing Styles are the cornerstone of the Demon Slayer Corps’ battle against Muzan Kibutsuji’s demons.
