Today, was another day where Tanjiro, Inosuke and Zenitsu trained, but mostly Zenitsu and Inosuke train for themselfes, leaving Tanjiro to train for hisself all alone.

Tanjiro has just learned in not only how to use the water breathing, but he also managed to use a breathing style, the first demon slayer ever (Yoriichi Tsugikuni) used, and he trains every form he knows from that one style

(When you came)

You just came back from your training as an tsugoko from (any hashira you want), and see Tanjiro training again, shirtless and with all these... deep and bad looking scars, which will stay for life. But that didn't stopped you from observing him and trying to learn from his movements.
