(To Tanjiro Kamado) "How can you feel sorry for something that's killed humans? I've never heard of anything so absurd. But if that was how my sister truly felt, then I must carry it on. If there's a way not to kill these pitiful demons, I have to keep trying to come up with it. Without ever extinguishing the smile my sister said she loved..."

(To herself, responding to a question Tanjiro Kamado asked in the past) "Yes, I'm angry, Tanjiro. I've always been angry. My parents were killed. My older sister was killed. And all my Tsuguko except Kanao were killed. If demons hadn't murdered those girls' families, they'd be living happily with them right now. It really makes me furious!"

(To herself, recollecting her childhood life) "I once believed that the road of happiness continued forever and ever into the distance. When it was destroyed, I realized for the first time that it lies upon a thin sheet of glass. And just as we were saved, there were those whose happiness that haven't yet been destroyed.
