Yamai was originally one Spirit, but for some unknown reasons that may be related with her teleporting between dimensions sometime in the past; she was split into two bodies and minds. The original personality of Yamai is now gone, as well as what type of personality she used to have is unknown to the split Yamais. The Yamai Sisters have been well known to the people who knew about the existence of spirits because they often cause a major storm in an area, that occur every time they come to Earth.

Yuzuru often speaks in a robot-like speech pattern; when arguing with Kaguya, she always sneers at her and points out the flaw in Kaguya’s argument. She tells the point of comment before speaking the rest. For example, "Confirm; Shido". She also speaks in a third-person perspective sometimes.
