Sayuri has long light brownish grey hair and small figure. She has grey eyes. Her smile, rarely observed, is devastating. And if she is mad, things are gonna get wrong. Her usual faces is just plain emotionless.
Muranushi is a young woman who shows little expression and speaks in a monotone, a trait inherited from her mother. She has the strange behavior of serving an invisible "elderly customer" despite claiming to not believe in ghosts as she has never seen one. Though rarely shows, she can be quite scary when she's angry. Like the rest of her co-workers, she has developed a trauma over Miyakoshi's home-made chocolates. And most of the time she doesn't talk. She claims that she actually want to smile but is confused by the reactions made by others who saw her smile, so she usually avoids doing so.
Almost a year before the start of the series, she was forced to accept Miyakoshi's chocolates on Valentine's Day when she lost at Rock-Paper-Scissors.
When she was in elementary school, she smiled at a boy who bullied her, changing his personality drastically.

When Adachi accidentally blurted out saying he doesn't want to go out with her, it caused her deep misery to the point of getting extended sick leaves and causing ghosts to haunt Wagnaria. In Episode 9, Adachi finally confessed to her, and they went out officially. At first it was still unsure whether Adachi really likes her, or was forced to confess to end her sickness and protect Wagnaria. In the Final episode she and Adachi left Waganaria and both work at Adachi's Sushi restaurant and she lives at his place which shows their relationship has progressed.
