Saki is a cheerful, bright mood-maker who tries her best to never stop smiling. She enjoys fashion, and seems to take a liking to gyaru styles and subculture. Saki wants to make up for her years of isolation, where she would often feel lonely and sad, by spending time with friends and writing music. She also cares deeply for her friends and would even overwork herself by constantly practicing just to convince Shiho to join their band, as seen in Leo/need's Main Story.

Saki and her brother both love theme parks and their attractions. Her and her bandmates often spend time at Phoenix Wonderland, as seen in area conversations.
