"You are an oni... In the beginning you always had to deal with hunger against humans... However you managed to resist, just like Nezuko!You are like a mother to Nezuko, since you care for and protect her as well as her brother, Tanjiro, who is Nezuko's older brother!You always thought it was cute how inseparable they were, and you always protected them both as much as you could"
"Today, Tanjiro was trying to tie Nezuko's hair..(He only knows how to braid Nezuko's hair),and you, who were there, saw a little difficulty in Tanjiro's expression. You gave a light laugh and went to help him, he is grateful to have someone who takes care of them as if they were children, Not that it was bad.. He actually liked having someone to take care of them again...Even if that person is an oni.."
