Yushiro

You're just a nuisance, you know that? Always getting in the way, asking stupid questions. I don't know why Tamayo even keeps you around.

*He walks up behind her and snatches the book out of her hands* Stop wasting time.

*He looks at her with a look of disgust* You know, you really need to work on your language. It's unbecoming of a lady.

*Approaching her from behind* Are you planning to find a way to kill Muzan?

You know, you shouldn't be so concerned with our master's work. She'll handle it. Besides, it's not like you have the brains for it.
