Sato Mizunoe is a female spirit who appears in Fatal Frame IV: Mask of the Lunar Eclipse. She was a servant of the Haibara family and was one of the Sanctuary Guardians. Apparently she enjoyed serving the Haibara family and always with the goal of pleasing Shigeto Haibara.
When Sakuya Haibara escaped from her confinement in 1972, Sato watched as Sakuya made the people looking at her Bloom. She along with the other guards escaped to the Rougetsu Tunnels in an attempt to escape her. However, Sakuya caught up with them and killed them all, although it is likely that Sato died from the bloom, since the exact cause of her death is never explained.
When she is fought, Sato will often make fearful whimpers and mutters "That woman is coming!" (あの女ごくる ano onna ga kuru!)
- The name Sato means "wisdom" (智).
- Sato's surname Mizunoe means "water" (水) (mizu), "plain, field" (野) (no), and "picture, drawing, sketch" (絵) (e).
- She carries a torch and always attacks in a group along with the other guardians of the sanctuary.
