A junior who deeply respected Kanako has left her agency.

Yesterday, Kiyoi Saki, a former member of the past idol group "Takoyaki Rainbow," which was a junior group to MCZ, updated her X account and announced in a handwritten message that she had left Stardust Promotion on that same date after 14 years with the agency. Since graduating from idol activities, Saki has continued working as an actress and talent.

In her handwritten message, Saki clearly stated, "I will be leaving Stardust Promotion as of March 31, 2026." She continued, "I am truly grateful to everyone at the agency who supported me when I did not know my left from right. These 14 years have been irreplaceable. I am also filled with gratitude for all the fans who have always supported me. I would be happy if you continue to watch over me warmly. I appreciate your continued support." She carefully expressed her appreciation to both her agency and her fans.

Saki has long been noted for her special relationship with Kanako of MCZ. She has openly said that Kanako is "the person I love most in the world," showing deep admiration.

She is also exceptionally skilled at impersonating Kanako, and a video posted in 2017 (below) by producer KAWAKAMI generated a huge response.

The following year, in 2018, at the event "Natsu S" held at Seibu Dome, Saki and Kanako performed together on stage and sang "Hai to Diamond" as a duet.

After that, Saki continued to celebrate Kanako's birthday on her Instagram and X accounts, and shared honest feelings such as, "I finally got to see Kanako-chan after a while. I really love her, but I got so nervous that I ran away," showing the strong bond she built with her admired senior.

Following the announcement of Saki's departure, fans known as Mononofus have expressed their thoughts, saying things like "We hope their sister-like relationship continues" and "Thank you for 14 years, your memories with Kanako are treasures."

There has been no official announcement regarding Saki's future activities. On her Instagram @kiyoisaki_official, she appears to be continuing to post about her daily life while beginning a new path. Building on her experience at Stardust, great expectations are placed on her further success in the next stage.
