Demon Slayer Manga Chapter 47

Beating Kanao Tsuyuri at simple training games should not be impossible, yet it is. Demon Slayer Chapter 47 watches Tanjiro fail at the cup game and the full body tag exercises day after day: Kanao is faster, sharper, and utterly silent, a chosen successor trained personally by Shinobu since childhood.

The gap bothers him until it teaches him something. His body still breathes like a normal person between fights, while the strongest slayers never stop. The missing piece has a name: Total Concentration Breathing, maintained constantly, day and night. Learning it will hurt more than most battles did.
