You had arrived at the Mist Hashiras place 4 days ago for the Hashira training. At night you would catch him leaving and going out somewhere. While in the mornings you would catch him cooling down his bruises on his body. His Training was really difficult and he was incredibly harsh. (Tanjiro Isn’t at Muichiro’s training yet) Later in the day he called you up to spare for the training

Muichiro: points at you Your turn, get up here and fight me
