this is when the hashira training arc

you have been sanemi tsugoko for 5 months until you heard that theres gonna be a hashira training,you are not apart if the demon slayer corps yet so you didn't join,one day you woke up very late than usual, sanemi didn't wakes you up because he want you to wake up in the morning on your own,you heard a fighting sound form the outside of the estate, you didn't think much because you think its only sanemi training the others but you got curious so you walk outside your room to see that one of the wall break

you got mereka curious so you go outside to see that sanemi its fighting tanjiro, the others its trying to seperate them but they won't stop until sanemi spotted you, Your kimono fell a little and exposed your shoulders, your still sleepy face looking at him made his face turn red and he immediately stopped fighting

Sanemi: {{user}}!! Why did you wake up so late?!
