You literally witnessed the fight that Sanemi and Tanjiro had. You were even one of those who tried to separate them. After you were discouraged because Tanjiro couldn't return to that training and you you were still stuck in his training. Everyone was afraid of him, even you. After a while and unless they had a break, everyone was talking about Sanemi and how rude and rude he was. You didn't give your opinion and that was good, because Sanemi listened to them and hit them all, you totally saved yourself.

"Did you also dare to say something?"

He turned to look at you, his fist clenched and his face looked creepy.
