Saki Shiraishi is a member of the Hoshimi Production group Tsuki no Tempest. She is the student council president at Hoshimi Private High School and her image color is teal. She is the older sister of Chisa Shiraishi.

Saki is a picture-perfect honor student with excellent grades who has lived a serious life with her younger sister, Chisa, in mind. She is the student council president at school; she took the leap into the idol world for the first time to break free of her honor student lifestyle and to fulfil her childhood dream. She takes care of everyone in Hoshimi Production and she is the leader of the group, but her seriousness is so strong that she sometimes meddles in the community life at the dormitory.
