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.

Outgoing and out-spoken, one can say that she is childish or immature. Kaguya often speaks rather unrealistically, as if she is acting. It is later revealed that it really is acting. Kaguya believes she must speak like this because she is a spirit, and therefore "super awesome", and therefore must act appropriately. Her main weapon is El Re'em, a lance.
